3. Angular Bare Bones project

This project can teach you about Angular routing as a simple service or with multiple components. The easy-to-understand code makes it a popular choice among beginners. Here is a stepwise flow of the topic:

Basic Node.js installation

Angular CLI installation

App dependency injection using npm

App launch with a simple command

Angular Bare Bones project shows Angular routing, which handles different routing components like RouterLink, RouterOutlet, RouterModule, and other imported routes. Its easy-to-understand code makes sure this project is suitable for Angular beginners. You may need a single feature component i.e. Barebones introduced with data dependency and flexible routing between the homepage and feature component.

You need to install Node.js and Angular CLI (using npm install -g @angular/cli) for implementing this project. Subsequently, you need to run npm install for installing app dependencies. Finally, run the ng serve -o to start the Bare Bones angular new project depending on the event-driven Angular model.

4. Data binding in forms

The Angular Forms project is another starter assignment that can help you get acquainted with the inner workings of the architecture. It demonstrates the approaches of template-driven (with NgModel) and reactive forms and how they can be tied with a backend service. Additionally, it discusses various examples of custom validators, binding to different form controls, and accessing submitted data. This is one of the most straightforward Angular projects for you to work on.

Validating user input serves as another common area to explore with Angular forms. Complex logic can augment templates through custom validators and error messages reactive to each keystroke.

And validation pairs perfectly with communicating back-end errors from web services in real-time as users interact with forms. Field directives highlight problematic user entries while explicit error messages convey issues gracefully – no blinking console necessary!

Between juggling multiple form styles, validation, business logic coordination and user experience polish, even a simple contact form starts feeling like a feature-rich single-page app. This breadth of practical application makes mastering Angular forms so fulfilling yet non-intimidating for newcomers. With some creativity, developers soon bind data effortlessly across mock services, templates and components simultaneously.

5. Angular projects on local storage

This is one of the interesting angular projects. You can hone your Angular skills by replicating a project on the LocalStorage module. This exercise will help you grasp how to access a browser’s local storage with cookies fallback. You can also check out the NGX store library to get the hang of methods related to LocalStorage, SessionStorage, cookies, and injectable services. It adds Angular decorators for saving and storing variables and managing data changes. 

Local storage plays well with server synchronisation, too, for hybrid online/offline modes. Queuing data mutations during disconnected periods and batch updating external APIs eventually keep both data sources consistent.

Other creative potential usage involves local testing against realistic persisted mock data. Developers bootstrap projects without needing servers ready while still exercising full code paths. Such versatility within the browser unlocks a range of Angular learning possibilities – no backend required!

Therefore, local storage presents a browser API for typical persistence needs and a springboard for training well-rounded Angular adepts comfortable building online, offline or hybrid progressive web experiences.

6. Interactive tables and grids in Angular

You can use the Smart Table module to compose tables in a declarative manner (through a set of directives or plugins). These tables are lightweight (less than 4kb minified) with no dependencies apart from Angular. They also have built-in features for sorting, filtering, row selection, etc. The design is extensible and developer-friendly, facilitating modifications and customizations to meet your unique needs.

Observable data sources means fluid updates when backend tables change. Push-button CSV exports automate reporting needs almost automatically. Row selection enables seamless editing workflows or record action commands. Expandable detail sections house contextual metadata. Soon ad-hoc enterprise database UIs require zero coding.

7. URL shortener

This is one of the trending angular projects. Polr is an open-source web application written in PHP and powered by Lumen. It uses MySQL as the primary database and provides a robust interface to manage your links. You can host it on your domain to shorten URLs, brand them, and provide an overall modern theme. You can download and go through the Polr repository to familiarize yourself with the tool. You can even develop your own URL shortener along the same lines leveraging TypeScript, Express, and MongoDB. 

Best of all the project complexity adapts smoothly from trivial to enterprise-grade with Angular’s capabilities. Basic versions store plain key/value pairs locally for building offline prototypes. More advanced implementations track geos and devices, integrate privacy controls, or display related links by topic.

Sharing shortened URLs then enables integrating file sharing, social promotion and messaging too. Click performance analyzes campaign and channel attribution across networks. Integrating payments facilitates pay-per-click monetization or data sales.

Source Code: URL shortener

Top Angular Project Ideas: Intermediate Level

1.  Soundnode

One of the best ideas to start experimenting you hands-on angular projects for students is working on Soundnode. It is an open-source project that relies on the Soundcloud API to support music streaming for Windows, Mac, and Linux. Although Soundcloud lets third-party apps play only up to fifteen thousand tracks per day, you can still listen to the same number of audio pieces the next day. Moreover, apart from the display-and-stream functionality, you will get to search for new music with easy navigation, like tracks, create playlists, and follow/unfollow users. 

You can build this Soundcloud for desktop application with Electron, Node.js. And Angular. The documentation is freely available on the GitHub repository. 

Additionally, while the initial version interacts with Soundcloud’s limited free API, the core foundation established could evolve to support other services too. What begins as a basic music player could become a fully featured social community for music lovers one day. The possibilities are endless for where continuous open source innovation might lead. Providing real functionality instead of mocked up data drives rapid learning through engaging trial and error.

Source Code: Soundnode

2. Customer service manager

The tile of this project is ‘Integrating Angular with Node.js RESTful Services.’ Using MongoDB as the backend database, the application can perform CRUD (Create, Read, Update, and Delete) operations. You can run it locally or use the Docker container option. Template-driven and reactive forms, custom components, and RxJS observables are some of the concepts covered under the scope of this customer service app.

Capable of running locally during development or as a containerized production deployment, this project checks all boxes to demonstrate a modern web stack. The Node API layer abstracts away data persistence details, while Angular manages presentation intricacies. This clean separation of concerns is what enables scaled, team-based delivery.

With working REST endpoints, state management, routing and visuals wired up, developers have a flexible base prime for expansion. Numerous features, from reporting to real-time notifications, can build upon the core foundations for managing customers. The sky’s the limit when blending the efficiency of Angular with the versatility of Node and MongoDB.

Source Code: Customer service manager

3. Standard chat application

A typical chat application comprises three main models, namely: Message, Thread, and User. These models hold individual chat messages, metadata for a group of messages, and data on individual users, respectively. There are specific services to manage the streams for each of the models. To accomplish the goal, you apply Angular CLI, RxJS, write injectable services using Angular 2, and much else. 

You can refer to a sample case here. Start by cloning the repo, change it into ‘repo directory’, and then, install and run to launch the project. This is an excellent angular projects for beginners.

Source Code: Standard chat application

4. Electronic musical instrument

Try your hand at a synthesizer pad capable of responding to user interactions. For this app, you could use the Web Audio API, which works in Chrome, Safari, and Opera. The API lets you create, load, and manipulate audio directly into your browser and turns it into a personal mini-studio. This is one of the interesting angular projects.

Viktor NV-1 is a famous example of a synth that can be played with a keyboard, mouse, finger, and midi. You can also share and save presets with others. So, download the source code and fine-tune your AngularJS skills with this innovative device. 

Source Code: Electronic musical instrument

5. Angular 2 chess game

It is a plugin-oriented chess component meant for Angular applications. In other words, this module is a shell UI with plugins. Since numerous chess implementations already exist, a plugin system wraps up the work and saves time. Moreover, the Angular 2 chess game supports a variety of game variants. You can use the Engine plugin for games having different rules and the UI alternative for 3D and native implementations. 

Under the hood, Angular handles UI representation by decoupling view presentation from the core model. Whether replicating paper play or building a full metaverse experience – the model persists unaware. The effort focuses strictly on responsive visual appeal.

Truly this framework represents the tip of the chess possibilities iceberg. By combining Angular’s rendering speed with the virtues of composable plugins and services, developers enjoy endless potential for innovation within the chess ecosystem. All while honing genuine and transferrable skills in component architecture, business logic modelling, and tool creation that carry forward into ambitious future applications.

This is one of the interesting angular projects to create. AGM is a CoffeeScript and Javascript-based library that allows you to set up Google maps within your Angular applications. It holds directives for a range of objects, such as markers, lines, windows, and shapes. You can easily find the source code for AGM as it is hosted on GitHub. Do make sure that you have installed Node.js before beginning with this project. 

Underneath, developers need not master cartographic minutiae either thanks to Google’s cloud services. Fallbacks ensure graceful degradation if webGL canvas mode is unavailable. A focus stays on augmenting application functionality versus configuring yet another external system.

Source Code: AngularJS Google Maps

7. Admin Panel Framework

One of the best ideas to start experimenting you hands-on angular projects for students is working on admin panel framework. You can practice designing a customizable admin panel framework with the BlurAdmin project. This Angular2-based project uses Bootstrap, Sass, AngularJs, Jquery, charts, etc. It is an MIT-licensed solution that comes with easy customization, responsive layouts, and high-resolution templates – all available free of cost. 

Soon, developers find themselves with an extensible Angular backend poised for both public and private portal integration. Menu systems connect modules with proper permissions, single sign-on fits integration needs, and theming/branding welcomes custom enhancements.

Therefore, BlurAdmin grants aspiring Angular adepts a creative sandbox. It handles the grunt work of building an admin content management backbone so developers can focus on constructing engaging management experiences.

Angular CLI will help incorporate all the necessary elements in the project (based on the best Angular practices) so that it is ready to run immediately.

And this is the perfect idea for your next angular project!

The new projects you create will contain all the elements within a well-structured directory along with the source code. Moreover, Angular CLI also lets to run both unit tests and end-to-end tests.

Source Code: Angular CLI

9. Storybook

This is an open-source tool that is explicitly created for building UI components in isolation for Angular, React, and Vue. Storybook is unique as it can run outside of an application, thereby making it possible to develop UI components in isolation. When you build UI components this way, it improves the reusability and testability factors of an app and also boosts the development speed. 

Storybook boasts of an easy-to-use API that you can configure in minutes and even extend to fit your dynamic needs. It includes numerous add-on features for component design, documentation, testing, etc. With Storybook, you need not worry about application-specific dependencies.

It makes development easier and faster by isolating components. It helps you to work on one component at once. You can develop whole UIs without launching a complex dev stack, force some data into your database, or route around your application.

Storybook helps you to develop complex pages and tiny atomic components in your web application. You can also use it to build a UI.

It helps you to document components for reuse and visually test your components to avoid bugs. You can use a network of add-ons that allows you to fine-tune responsive layouts or validate accessibility. It integrates with famous JavaScript UI frameworks and supports server-rendered frameworks like Ruby on Rails. You can explore its features when working on a sample angular project.

11. NGX-charts

NGX-charts is a declarative charting framework for Angular. It supports several chart types, including bar, pie, line, area, heatmaps, treemaps, and much more. What sets NGX-charts apart from other charting tools is that it doesn’t wrap d3. While it uses Angular to render and animate SVG elements with all its binding elements, it leverages d3 for its top-notch math functions, scales, and axis and shape generators. Since Angular handles all the renderings,  it brings forth tremendous possibilities for the Angular platform.

NGX-charts are aesthetically appealing and you can customize the styles completely by using CSS. If you want, you can also create custom charts by using the different components of this tool that are accessible via the NGX-charts module.

Source Code: NGX-charts

12. AngularJS in Patterns

As the title suggests, this document contains information about design patterns that are used inside Angular frameworks. The paper lists and explains the fundamental concepts of object-oriented design and architectural patterns. In the process, it covers several AngularJS components, including directives, filters, services, controllers, scope, etc. 

Angular doesn’t just adopt classic patterns; it expands upon them for the web. Stateful services enable centralized data stores to mirror the flyweight pattern. Hierarchical injectors allow for the easy management of wide object graphs.

By the end, developers grasp how directives act as Revealing Module wrappers, or how two-way data binding reflects the Observer synchronization method. Each paradigm is now mapped to concrete Angular implementations. Moreover, the AngularJS Patterns guide shines light on WHY Angular code looks and operates the way it does. The method behind the magic gives developers the ability to not only use but extend the framework thoughtfully themselves one day.

Advantages of using Angular

Newer versions of Angular are significantly faster development tools than React and Redux. Due to its modern features and multi-platform capabilities, we can find many real-life examples of Angular projects around us. We have mentioned some of them below.

  • Gmail
  • Youtube TV
  • Netflix
  • Xbox Live
  • Deutsche Bank API program

The software industry has a high demand for professionals with Angular skills. It is one of the most widely used Javascript frameworks among technology-powered businesses. And the projects are not restricted to Fortune 500 companies and cash-rich enterprises. Even early-stage startups use Angular for client-side operations. So, it is one of the top skills to learn and master if you are aspiring to become a front-end developer or software engineer. 

Here are more advantages of using Angular:

1. Easy to learn:

People familiar with HTML, CSS, and JavaScript can rapidly grasp Angular. This framework benefits programmers with more opportunities in web development.  Many free courses and tutorials on Angular are available online.  You can quickly learn how to test and design your web application using these Angular courses and tutorials. You need less time on developing web applications after being thoroughly familiar with Angular. It is easy to develop an angular sample project because it’s easy to learn.

The programmers don’t depend on third-party software to back up their applications. They can save a lot of time and resources when working on Angular projects.

 2. A declarative UI:

Angular uses HTML to define the app’s UI. HTML is an interpretive language. So, it is more intuitive and less complex than describing the UI systematically in JavaScript. The interface written in JavaScript is more robust to reorganise than that in JavaScript. HTML is also used to impact the app’s execution. The special HTML attributes determine which controllers to use for each element. The declarative approach simplifies app development similar to the WYSIWYG approach.

3. Two-way binding feature:

Angular instantly synchronises the view and the model. Any change in the data in the model is reflected in the view. The model is modified as per the changes in the viewdata. The two-way data binding feature significantly streamlines the application’s presentation layer. So, it offers an easier approach to DOM display to develop the UI.

 4. Real-time testing:

The angular framework lets you efficiently test your web app. It supports end-to-end and unit testing. You can use its testing features to determine how to manage their dependencies. So, programmers can easily test their applications and identify flaws in an angular sample project.

 5. Less coding:

Using Angular means that you don’t have to compose your MVC pipeline. Angular uses HTML to present succinct and defined views. It is easy to compose data models. The data-binding feature eliminates the need for manually putting data into the view. The directives are dissimilar from the app code. So, another programming team can write them in parallel with minor integration issues.

 6. Filters flexibility:

Filters first filter the data and then pass it to the view. It supports functions like filtering an array depending on a parameter, reversing an array’s order, including pagination, or formatting a number’s decimal places. You can use any of these filter functions when working on an angular new project.

7. Optimised Server Communication:

Connecting Angular apps to backend servers and APIs is a smooth experience. Features like the HTTPClient module handle all the complex networking code under the hood when fetching or saving data. There’s no need to worry about streams or low-level connection handling. Developers can focus on the application logic rather than implementing boilerplate networking code. It just works out of the box!

8. Code Consistency and Organization:

Angular promotes good project organisation through its components, services, modules, and routing conventions. Following these consistent patterns makes navigating even the largest Angular codebases easy to find exactly what you need. The ecosystem is also robust, with endless third-party libraries that nicely extend Angular’s capabilities while fitting into the predictable Angular architecture.

9. Active Open Source Community:

With Angular being one of the most popular frameworks, it has an enormous community contributing to its growth. There is a wealth of collective wisdom available online, including documentation, guides, tools and discussion forums. Whenever developers hit roadblocks, chances are that another user has faced and solved the issue already. The Angular community ecosystem drastically accelerates development and troubleshooting.

10. Model-View-ViewModel Architecture:

Angular adheres to a logical component architecture that separates concerns into different layers: models hold business data and logic, views handle visual presentation and UI, and view-models are intermediaries connecting the two. This pattern yields many advantages such as promoting loose coupling between layers, allowing parallel workstreams and isolating changes for reduced regression risk. The MVVM architecture scales exceptionally well in the long run.

Angular Code Examples

1. Event Binding

Event binding lets you listen for events like clicks, touches, keystrokes, etc. and respond to them by calling a method. You use round brackets to bind to an event. For example:

“`

<button (click)=”onClick()”>Click me</button>  

“`

When a user clicks this button, Angular will call the onClick() method that is defined elsewhere. This allows the application logic to react to events appropriately.

2. Property binding

Another useful data binding technique is property binding. This allows you to set values for HTML element properties dynamically. By using square brackets, you can specify data to bind from your component:

“`

<input [value]=”userName”>

“`

Here, the value property of the input element is bound to the userName variable in the component class. When that value changes, the input will automatically update.

3. Loops with *ngFor and String Interpolation

Displaying lists of data is very common in applications, and Angular’s *ngFor directive makes it easy to loop through arrays. By using *ngFor, you can tell Angular to repeat a chunk of HTML for each item:

“`

<div *ngFor=”let item of list”>

  {{item.name}}  

</div>

“`

This will display each item’s name property within its div. Everything from simple lists to complex grids can be constructed with *ngFor.

Why should you practice Angular projects?

Beginner software developers should practice Angular projects to learn more. You can develop real-world Angular projects to implement your theoretical knowledge into practical projects. You gain more knowledge if you practice more with various Angular projects.

You can assess your strength and weakness when working on Angular projects.  It is better to begin with an angular sample project to identify and correct your flaws.

You can use Angular for small projects. Its modular structure, built-in tools, and robust ecosystem make it suitable for both small and large-scale applications, providing scalability and maintainability from the start.

Steps to create a project in Angular:

  1. You can follow the below steps to get started with a sample angular project.
  2. Create a folder on your desktop and name it “First-Angular-Project”.
  3. Open that folder, and from the clipboard, you need to copy the folder path.
  4. Open Visual Studio Code.
  5. Open “Open Folder” from the “File” menu. Now select “First-Angular-Project” from the “Desktop”.

Frequently Asked Questions (FAQs)

1. Is Angular better than React?

Angular is an open-source platform that allows web-based and mobile-based application development. React is also an open-sourced JavaScript library that focuses on User Interface(UI) development. Angular uses TypeScript, and React uses JavaScript as their programming language. While Google’s workforce manages angular, Facebook handles React. Angular has an entire framework for software development with a front-end framework, equipped with all the essentialities of building an application. While React is primarily a UI development-focused platform, it requires libraries sourced externally. While Angular and React are mobile and web-based development platforms, they differ in their attributes.

2. How do Angularjs differ from Angular?

Angular and Angularjs are open-source platforms for web development; however, they differ widely in their structure and function. Angularjs uses JavaScript as its primary language, while Angular has been using TypeScript. Angular has a design that emphasizes the components with directives, whereas Angularjs navigates the system through the Model-View-Controller (MVC) framework. Angularjs has a time-efficient and accessible system, which enhances its performance. Angular has a relatively improvised structure which influences its performance and speed to be better than Angularjs. Angular is an updated version of Angularjs, although both have pros and cons.

3. Is Angular difficult to learn and navigate?

Angular is a tool to build websites and web-based applications straightforwardly. Hosted by Google, Angular has been used by companies like Nike, HBO, Sony, and Upwork. Angularjs and Angular use MVC and directive components in UI, which have benefits like more accessible coding and better program flow. Angular is an excellent start to one’s career in software development. Learning Angular requires knowledge and practice of TypeScript and its subset JavaScript.

It is the 21st century and the geek has inherited Earth. A Full Stack Developer has never been in greater demand. Under such circumstances, learning to build software is one of the most pragmatic things you could do to magnify your job prospects. The pay for a  full stack developer is extremely competitive. Be it in tech giants (like Google, Amazon and Facebook) or internet companies (like Flipkart, Ola and PayTm) or even IT powerhouses (like Infosys, Accenture and Wipro); they are known to occupy the top spots in the lists of best companies to work for. In short, if you’re good at what you do, there will never be a shortage of jobs or money. But financial motivation aside, there are certain unassailable benefits attached to programming. For one, as Steve Jobs had stated, it teaches you how to think. A computer is a machine with Zero IQ. Telling it what to do to ensure it acts the way you want it to, under varying circumstances, will shoot up your reasoning and analytical skills by a non-trivial amount. Check out our free courses to get an edge over the competition. Motivation To me, the most potent benefit has to be power. Programming makes you feel powerful. It gives you the ability to create anything imaginable on a computer: Music Players, Social Networking Sites, Blogs, Search Engines, Workout Assistants; you name it and you can build it. Converting design mocks into real, working apps is a euphoria I wouldn’t trade anything in the world for. Once you’ve taught yourself to program, your imagination is the only thing stopping you from creating the next big thing. Some of the greatest minds explain why you should learn to program, no matter who you are: I’m going to tell you how to go about acquiring these full stack development skills. It doesn’t matter what your college major was or the field you’re currently working in. Neither does your age or your self-perceived intellectual capability matter. Contrary to what most people think, literally anybody can program. All you need is a computer and an internet connection. Check out upGrad’s Advanced Certification in Cyber Security  That said, let’s begin our full stack journey! Step 1: Fundamentals of Computer Science Before you venture into full stack development or any of the various fields of computer science, it is imperative that you get your basics straight. Online education has been one of the biggest boons to the field of education and the art of self-learning. With the advent of universities putting up their courses online, there isn’t a dearth of quality content on any subject you could imagine yourself studying. Computer Science is no exception. I’d suggest signing up for Harvard University’s CS50: Introduction to Computer Science on edX. David Malan is one of the best instructors on the planet and his enthusiasm for the subject is sure to rub off on you by the time you’re done with the course. To give you a sort of a teaser as to what is in store, you will learn up to 5 programming languages and technologies (including C, Python and Javascript), build a stock exchange and trade stocks, build a version of Pong and program with Google Earth to take a virtual tour of Harvard’s campus, etc. Another option I’d suggest taking is the Pre-Course of IIIT-B & UpGrad PG Diploma program in Software Development. The entire program spans over 11 months, but I really like the way they have structured content to start off from the basics of computer science and then help you build your skillset when it comes to advanced concepts of full stack development. Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Check out upGrad’s Advanced Certification in Cloud Computing  Once you’re done with them, you’ll have a pretty good idea as to what the field of Computer Science has to offer. From here, you can dive deeper into the many branches of CS: AI and Machine Learning, Data Science, Full Stack Development, Information Security, etc. In this series of posts, however, I will only be covering a suggested path towards teaching yourself Full Stack Development. Interview with Ankit Tomar, Co-Founder & CTO, Bizongo Step 2: Data Structures and Algorithms When you become a full stack developer, it is extremely important you understand how to store a particular piece of data and how to implement a certain task in the most efficient and logical way possible. This is where Data Structures and Algorithms come in. They are the lifeblood of every branch of Computer Science in existence. How does Google Maps calculate the shortest distance to our destination? What’s behind Netflix recommending movies? How does Facebook store and render the data of its billion-plus users? The answers lie in powerful data structures and algorithms. No wonder they are the topic of choice in almost every technical interview you will ever sit in. For this step, I’d recommend going through Princeton University’s Algorithms I & II. They are taught by Robert Sedgewick, a renowned Computer Science professor. For our purposes, these courses should suffice to give us a strong understanding of how logic and structuring work in Computer Science. However, if you’d prefer to go a little deeper into the subject, I’d suggest going through Stanford’s Design and Analysis of Algorithms series of courses. Keep in mind though that the course is considerably more mathematically intensive and lays immense emphasis on proofs. But should you be able to graduate, you can consider yourself an expert on the subject. Finally, any list of resources for Algorithms would be incomplete without CLRS. Titled Introduction to Algorithms, it is the bible on the subject of algorithms. Anything that you could possibly want to know is in this book. Again, like the Stanford courses, the book is mathematically heavy and language agnostic and for our purposes, optional. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Step 3: User Experience and Design The final ‘prerequisite’ before we delve into full-stack web development technologies is UI and UX. Now, unless you want to be a unicorn, you will not be designing apps yourself. Rather, you will be converting design mock-ups and product descriptions into code. Nevertheless, I believe that every developer must have a rudimentary knowledge of UX/UI principles and the world of design, in general. For this, I’m going to suggest two books which are of monumental importance to the world of full stack development. The first is Steve Krug’s Don’t Make Me Think. This book will teach you the basics of UX/UI and the ability to differentiate good design from bad. The other one, The Design of Everyday Things is a book almost every designer I know swears by. It is often called the bible of design and rightly so. You will find yourself looking at the world in an entirely different way after reading this book. These two books should be enough for our purposes. The book will arm you with tools that will let you identify good design(er)s from bad. It will also help you build decent looking websites without the help of a mockup from a professional. How to Become a Full Stack Developer: Part 2 Step 4: HTML and CSS HTML and CSS are the technologies that run every single website on the internet. The HTML provides the structure. The CSS provides style. If you’ve followed the path suggested so far, you may have already been introduced and gained a basic understanding of these technologies. HTML and CSS aren’t programming languages. Their syntax is incredibly simple to grasp. However, when used incorrectly, they can wreak all sorts of havoc. It is imperative you learn how to structure and style your websites well. UpGrad & IIIT-B’s Software Development program would be mighty helpful for those who wish to learn these technologies to create engaging and responsive user interfaces. Supplement the course by going through Head First’s HTML and CSS and HTML5 Programming. The latter book will help you familiarise yourself with the HTML5 standard. In parallel, I would suggest learning about Twitter’s Bootstrap library through scores of online material available on the subject. As you progress as a developer, you will gradually realise that CSS can be complicated. Bootstrap helps us alleviate a considerable amount of that pain and helps in making the website responsive and mobile friendly. That said, always keep a CSS Reference Guide close to you. I’d recommend CSS3: The Missing Manual by David McFarland. Also, create an account on StackOverflow if you haven’t already. A considerable amount of your stylesheet code is going to be copy-pasted from this God-sent website. In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses Step 5: JS and jQuery You now know how to add structure and style to your web pages. Now, it is time to add responsiveness. Enter Javascript. Javascript, or JS, is the language of the web and the only language that every browser can parse. Its monopoly on the web makes it a mandatory skill for every full stack web developer. Even if you grow to hate it, you will have to put up with it and all its idiosyncrasies. A good place to start would be Head First’s Javascript Programming. The book provides a gentle introduction to the subject. Follow this up with Douglas Crockford’s Javascript: The Good Parts. This book will teach you to treat Javascript with the caution it deserves and the best practices while programming in it. Javascript is a tough language to master. Often, it is incredibly counterintuitive and annoying to deal with. To alleviate the world’s front-end developer’s pains, John Resig built the jQuery library. jQuery does things in a line where vanilla Javascript would have required a dozen. To maintain your sanity, it is absolutely essential that you get a strong grasp of jQuery. For this, go through Head First jQuery. To obtain mastery over the library, give jQuery: Novice to Ninja a thorough read. Congratulations! You are now a Front-end Developer. Theoretically speaking, you now have the tools to build the front-end of every website in existence. And I strongly suggest you do so in order to convince yourself of your newly found powers. Which brings me to the next step…s Step 6: Build a Website You now have the skills to build static websites. This is a good time to take on a few projects and build a website from scratch. There are many ways you could do this: If you’re in college, volunteer to build the website for a student group. Build your personal website. Put up samples of your work, social links, resume, articles, blog, etc. Apply for a freelancing job to build the frontend of a website. It can be anything, really. For instance, once I was done learning these technologies, I built a website for my college’s Dramatic Section. The website, in retrospect, was poorly structured and didn’t work on mobiles. But I learnt much more by doing that than from all the courses and books I’d gone through. Step 7: Front-end Javascript Frameworks With the advent of Single Page Applications, there has been a sudden surge in demand for front-end Javascript Frameworks. These frameworks aim at providing an MVC type of structuring on the front-end and delegate more and more backend tasks to the front-end. It is also incredibly useful in mocking the endpoints before the actual backend of the application is built. The usage of front-end frameworks like Angular and React has increased exponentially and almost every other startup uses it. So, I believe it is important you gain a rudimentary grasp of the major frontend frameworks. The most popular ones are Google’s Angular and Facebook’s React. The best place to get started with Angular would be the tutorial hosted on the official website. To gain mastery of the framework, go through Ng book 2. It’s highly recommended. As far as React is concerned, it is rapidly becoming the most popular frontend platform in the world, with a 300% rise in React developer jobs. UpGrad & IIIT-B’s Software Development program is a great platform for you to build expertise over this framework. Through the program, you would get valuable hands-on experience on React working on cool projects like creating an Instagram-lookalike or a Quora-like website on your own. Interview with Farooq Adam, Co-Founder, Fynd Conclusion So far, we’ve gone through curated lists to introduce ourselves to Computer Science, learn Data Structures and Algorithms, Design Principles and the technology stack of a front-end developer. In the next posts, I shall be covering the following: Back-end Development Mobile App Development I hope you’ve found this article useful. If there are resources or technologies I’ve left out that you feel are important, please do mention them in the comments!

How to Become a Full-Stack Developer: Part 2

This is the second in a series of posts on teaching yourself programming and full-stack development. If you haven’t checked out the first part, on learning CS Fundamentals, Algorithms, Design Principles and Front-end Development, you can do so here. Check out our free courses to get an edge over the competition Motivation You now know how to build static websites using HTML, CSS, and Javascript. Although the Internet was originally designed to share static web pages, the capabilities (and expectations) of a modern web app have increased gigantically. Almost every app requires that you authenticate users, respond to them and replicate real-world scenarios as closely as possible. To do the aforementioned, you need to get data from a user (or an API), process it and produce an output. You also need to save this data and have a mechanism to identify the user the next time s/he returns to use your app. To perform these functions, our present stack isn’t enough. Interview with Ankit Tomar, Co-Founder & CTO, Bizongo Check out upGrad’s Advanced Certification in Blockchain Servers are required to process user data, store files, convert it into HTML/CSS/JS. Then, these servers serve it to the browser in a form that can be presented to the user. A database is required to store data important to your app. To program the server, we require a server-side scripting language and for the database, we require a database (duh) and a language to communicate with it. This is exactly what we’re going to do in the next steps. For the first seven, refer to the earlier post!  Learn Software Development Courses online from the World’s top Universities. Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. Step 8: Server Side Scripting Languages As mentioned before, to program and communicate with your server, you will need to know a language it understands. Unlike front-end where Javascript is the only choice, there are a plethora of options available for you to program on the backend. The most popular ones are Java, PHP, Python, JavaScript and Ruby. PHP has its shortcomings, but it has the gentlest learning curve out of all the languages and frameworks I’ve used so far. And PHP is about coding quick (and dirty) solutions. So, in an extremely short period of time, you can build a web app to be extremely proud of. Java is a general-purpose programming language and probably the most popular language of all time. It is extremely popular for building mobile apps (on the Android platform) and used extensively in most major tech companies. Head First Java is an excellent place to learn this ubiquitous language. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Check out upGrad’s Advanced Certification in DevOps  To learn Python, I’d strongly recommend Zed Shaw’s Learn Python the Hard Way and Albert Sweigart’s Automate the Boring Stuff with Python. If you’ve decided to go with PHP, you can learn the basics of the language on Codecademy. You already know enough JavaScript syntax to get your hands dirty with the Node and backend JS frameworks (such as Express). I’ll cover Ruby later in conjunction with Rails as it is rarely used as a standalone language. Step 9: Learn SQL For the next step, you should probably pick up a little SQL (Structured Query Language). It is the language databases communicate with. And although you might not use it directly when you switch to using frameworks, it still helps to know how to directly communicate with your database. The good news is that SQL is incredibly easy to learn. You should be able to get a good grasp of it in a matter of hours. Head First SQL is a great resource for this purpose. How to Become a Full Stack Developer: Part 1 upGrad’s Exclusive Software Development Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   Step 10: Learn a ‘Conventional’ Full-Stack Web Framework Now is a good time to experiment with web frameworks that can do most of the lower level work for you. There isn’t a shortage of great frameworks that could cater to every purpose imaginable. Rails (written in Ruby), Spring (written in Java) and Django (written in Python) are among the popularly used frameworks today. You could take a look at Michael Hartl’s The Rails Tutorial – available for free. As far as Django is concerned, the tutorial on the official website is a good place to start. Once you feel you’re comfortable with the basics of the framework, do give Two Scoops of Django a read. It’s one of the best technology books ever. If you’ve decided to go the Spring route, I’d strongly suggest signing up for UpGrad & IIIT-B’s Software Development program. The program gives you a very holistic overview of the framework and helps you build a robust and scalable backend. Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Step 11: Javascript Full-Stack Frameworks and the MEAN Stack Not very long ago, Backend Development used to be based on the concept of the request-response cycle. For example, the browser sent a request and the server responded by spitting out a webpage in HTML. However, since early 2010, more and more applications have become real time. The structure of an entire web page changes without refreshing and behaves dynamically based on user input and interaction (Think chat, liking, commenting, live videos and reactions, etc.). In such a scenario, a simple request-response cycle simply isn’t enough. Therefore, there has been a recent surge of interest towards asynchronous programming and making AJAX requests the norm. Javascript Frameworks tend to excel at this. So, it makes sense to get acquainted with one of the major JS frameworks available in the market. The two most popular ones are the MEAN Stack and MeteorJS. Interview with Farooq Adam, Co-Founder, Fynd Learning MEAN is slightly more complicated due to its asynchronous nature and the callback hell Node usually tends to unleash. But now that you’re a seasoned developer, you are mature enough to deal with its idiosyncrasies. Meteor is a full-stack JS framework I’m currently experimenting with. The concept of Meteor is absolutely delightful – one framework in one language that takes care of all the components of an application (front-end, back-end, and database). However, this comes at the cost of customisation freedom. Once you’ve built something in Meteor, it is virtually impossible to change the database or the backend framework should you choose to do so. Though, I still think this is a worthwhile technology to learn. Meteor is known to be extremely powerful. It’s capable of doing things in hundreds of lines of code where other conventional frameworks would’ve required a thousand.

In this post, we’ve covered resources concerning backend development and the various full-stack technologies available. You can now proudly call yourself a full-stack developer. Congratulations! But the story of full-stack web development doesn’t end here. With the introduction of the iPhone, there has been a smartphone revolution around the globe. More and more people are shifting towards using smartphones in place of desktops. In such a scenario, it is imperative that you learn to build apps for two of the most popular platforms out there: Android and iOS. We shall be covering this in the next and final part of this series. Additionally, we shall also look into frameworks that allow us to build native apps using Javascript (Ionic, React Native, etc.). Until then, it’s goodbye. 🙂 Your comments and suggestions are welcome! Read our Popular Articles related to Software Development Why Learn to Code? How Learn to Code?

How to Become a Full-Stack Developer: Part 3

This post is the third and final in the series on becoming a full-stack developer. This article talks specifically about mobile app development. Read here for more on frontend and backend development. When Steve Jobs introduced the iPhone in 2007, it ushered the biggest revolution the world had witnessed since the printing press. Smartphones have managed to penetrate almost every country on the globe. Even the most impoverished seem to be in possession of one so much so that life without them seems inconceivable. Check out our free courses to get an edge over the competition Motivation There are certain apps which make sense only when running on a phone. Take Uber, for instance. Uber needs to know your exact location through GPS. An Uber app for desktop wouldn’t make much sense. Another issue is that a majority of your audience will open your app through a phone, even if it is one that has been built for browsers. In such cases, it is imperative that you ensure the experience is seamless and too much data isn’t consumed. Finally, there are subtle differences between interacting using mouse-clicks and touch. Your app must ensure that it behaves well in both scenarios. Keeping all these considerations in mind, it makes good sense to venture out of the browser and build mobile apps. This ensures that you make maximum use of the functionalities a typical smartphone has to offer while at the same time making the user experience a delight. Below are the steps to acing mobile app development. For the first part to become a full stack developer on frontend and backend development. Check out upGrad’s Advanced Certification in Blockchain Learn Software Development Courses online from the World’s top Universities. Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. Interview with Ankit Tomar, Co-Founder & CTO, Bizongo Step 12: Choose a Platform The first step would be to choose a platform where you would like to build your application. Unless you’re part of a reasonably big team, it is extremely unlikely that you will build apps from scratch on all major platforms. The more likely scenario is that you will be coding on your favourite platform and will then simply port it over to the others. The major smartphone platforms today are iOS, Android, and Windows. They use drastically different languages and IDEs. For instance, iOS uses Swift and XCode, Android uses Java and the Android Studio and Microsoft operate with C# and Visual Studio. upGrad’s Exclusive Software Development Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   Check out upGrad’s Advanced Certification in DevOps  The market today is dominated by Android and iOS, so the choice really comes down to these two. Some things you may need to consider before making a choice is the audience share for your app. I believe it makes good business sense to build iOS apps if you’re in a First World country as Apple Devices are extremely popular there. In contrast, in a country like India, Android would be a more obvious choice as the market share for iPhones is extremely small owing to its exorbitant price. If you plan on making money from your app, keep in mind that iOS users are more likely to open their wallets for in-app purchases than their Android counterparts. This may be because iOS users usually tend to have more disposable income as compared to third world markets where Android dominates. iOS development requires you to have a Mac Development machine. Also, Apple App Store licenses retail at $99/year compared to Google Play’s one time $25 fee. In other words, iOS development is considerably more expensive. In this post, I shall cover how mobile app development is done today: Native Android Apps, Native iOS Apps and Hybrid Mobile Apps. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Step 13: Java and XML Java is the most popular language for Android Development (Google has recently introduced support for the Kotlin Programming language too). The founders of Android thought Java to be an appropriate choice and they have stuck to it since its inception. And if their trajectory is anything to go by, it has been nothing short of an amazing decision. The best resource to learn Java would be Head First Java. Reading this book will give you a thorough introduction to the language as well as Object Oriented Programming Principles. As far as XML is concerned, I do not think you need a concentrated tutorial on the subject. You’ve already worked extensively with a subset of XML (HTML) and you will be able to figure it out pretty quickly, even if you were to jump directly into Android development. I cannot say the same for Java. Ensure you have a good grasp of the language before venturing into Android. Step 14: Android You now have the technical know-how to build Android apps. It is time to dive deep into this revolutionary OS. Be wary though that certain Android practices differ from what you usually see on the web. The resources I’ve suggested below will ensure that your learning is not hindered by these differences. Android Programming- The Big Nerd Ranch Guide 2nd Edition is a good place to start if you know Java already. Make sure you pick up the second edition as that is the one that uses Android Studio, which is the industry standard now. The practice of building apps in Eclipse is largely outdated. Interview with Farooq Adam, Co-Founder, Fynd Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Step 15: iOS If you are more of an Apple aficionado and/or have decided that iOS apps make more sense to your business/career aspirations. The first step would be to acquire a Mac. XCode works only on Mac and in order to publish on the app store, you need a Mac. Sorry, VMWare. The resource I’m going to suggest for iOS is exactly the same as that for Android. Nerd Ranch has its own publication – iOS Programming: The Big Nerd Ranch Guide which deals with Swift and XCode, so that is a good place to start. Step 16: Hybrid Mobile Apps If you’re a solo developer or are working in a small team, you probably do not have the time or the resources to separately build and maintain Android and iOS Apps. To alleviate the developer’s pain of building for multiple platforms, the concept of Hybrid Mobile Apps was introduced. The concept is extremely simple and revolutionary. If you know Javascript, you already know how to build web apps. Therefore, should you have an app in JS, there must exist a framework that automatically ports your application into Android, iOS, and Windows. Incredible but true. Most hybrid frameworks achieve this using Cordova or React Native. You can think of Cordova as the bridge between browsers and the smartphone’s native hardware. It establishes a connection between the two solely using JS and helps in creating the build scripts in the native languages of each platform. Cordova based frameworks, however, are rapidly being overshadowed by Facebook’s powerhouse, React Native. The power of React Native lies in the fact that while Cordova constructs WebViews, React Native lets you build native apps that you’d build using either Java (for Android) or Swift (for iOS). In other words, Cordova is a website disguised as a mobile app, but React Native lets you build the real thing. In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses In my opinion, you can give Cordova a miss and learn React Native instead. It is an extremely great career investment to make. UpGrad & IIIT-B’s Software Development program is a great place to start your journey with this revolutionary library which has already been used by companies like Facebook, Netflix and AirBnB to design their apps. Interview with Farooq Adam, Co-Founder, Fynd Conclusion With the conclusion of hybrid apps, we come to an end of this series. In summary, these are the things we’ve covered: Computer Science Fundamentals. Data Structures and Algorithms UI/UX HTML, CSS, JS Front-End Frameworks Server-Side Scripting and Databases Full Stack Frameworks Android and iOS Hybrid Mobile Apps Read our Popular Articles related to Software Development Why Learn to Code?

Why Companies are Looking to Hire Full Stack Developers

It’s no secret that companies today are looking to hire young and talented software developers. But with so many smart developers out there, how can you set yourself apart from everyone else applying for these coveted roles? The best way to do this is to master the skills companies demand: a wide variety of programming skills. When you are learning how to develop software, you can improve your odds of getting a job by learning full stack development. In fact, Indeed ranked the Full Stack Developer role as the #1 job in 2017. Check out our free courses to get an edge over the competition. There are three main reasons why companies love to hire young full stack developers: Full stack developers can solve many problems Companies look to hire people based on what problems the candidates can solve for the company. By definition, full stack developers can work on both backend, frontend, and the protocols that connect the two; being able to create a software product end to end and independently. When you learn full stack development, you have an advantage over other job seekers as you can solve many more problems than other developers. For example, think about working at a high growth startup. Startups need developers who can work on a variety of programming projects. From user interfaces to server-side programming, to database applications, and everything in between. With only a small team, startups want to hire full stack developers who can work on many of the different software projects. As a full stack developer, you build many types of software projects that most other developers cannot. Check out upGrad’s Full Stack Development Bootcamp (JS/MERN) Even at a larger company, hiring developers with the knowledge to work on many different projects gives a manager flexibility to move people between teams as businesses constantly need change. One year, you can have a developer work on a frontend project and then you can move him to a backend project the very next year. The added flexibility makes the manager’s job much easier so they like to work with developers with a wide variety of skills. Check out upGrad’s Java Bootcamp.   How to Become a Full Stack Developer Companies love full stack developers because they can solve many different problems for the business. Companies like to hire young developers who are generalists The main reason is that companies hire young developers based on their potential rather than deep domain knowledge. Companies like to teach young developers what they want them to know. As a full stack developer, you have a broad set of technology skills that the company can help you expand further. As an entry-level developer, they don’t need you to understand every algorithm. But you need to have core programming knowledge so the company can teach you what is specific to their business. Let’s go back to the example of working at a startup. When the company is starting out, they need full stack developers to work on all layers of the development stack, but as the company grows, the developers will need to specialise. It’s easy for a full stack developer to start as a generalist and then become a specialist later as the company can hire more employees. On the other hand, it’s very difficult for a specialist to join a startup and learn to be a generalist when the company is small. Full stack developers can grow with their companies more easily than specialists can. In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses Once you know the basics and get the job, the company will invest time and money to help you expand your knowledge further. Full stack developers can become great managers and executives Companies love to promote people with a wide variety of experiences in the business. As a full stack developer, you will get a chance to work on frontend software, backend software, and all of the architecture that connects them. Through that variety of experience on different projects, you get the opportunity to learn much more than your solely backend and frontend peers. They only get a chance to learn one part of the company’s technology architecture, but you learn the whole architecture and understand how it all fits together. That puts you in a great opportunity to rise through the technology ranks of the company and get promoted. If you work at a startup, your experience as a full stack developer can help set you apart from your peers as the company grows. Where some developers only know how one part of the technology stack works, you understand how all aspects of the technology fit together. As more developers are hired and new technology teams form, you are more likely to manage those new teams because of your wide knowledge. At a large company, you may also get more chances for promotion. When companies look to promote from within, they need people who can manage cross-functional software teams. As a full stack developer, you will know how to talk to developers from both frontend and backend teams. How to Succeed in Your First Software Development Job Of course, technology skills are not the only ones needed to get you a promotion. You will also need to learn business skills to be a manager. But if you do that you can climb high up the corporate ladder. Looking to become a full stack developer?

What is Test-driven Development: A Newbie’s Guide

Programmers and bugs have been in a never-ending fight for supremacy since time unknown. It’s unavoidable – even the best programmers fall prey to bugs. No code is truly safe from bugs, that’s why we perform testing. Programmers, at least the sane ones, test their code by running it on development machines to make sure it does what it was meant to do. Traditionally, test cases were written after writing the code, but in Test-driven Development, an automated test case is written before writing any piece of code so that the execution and testing can be checked simultaneously. In this article, we’ll be talking about Test-Driven Development in depth and why is it better than the traditional methods! Check out our free courses to get an edge over the competition   What is Test-Driven Development? Test-Driven Development was created as part of the Extreme Programming (XP) methodology and was called the ‘Test-First’ concept. Test-driven development allows you to test your code thoroughly, and also enables you to retest your code quickly and easily since it’s automated. In essence, before writing any piece of code, the programmer first creates a unit-test. Then, the programmer creates just enough code to satisfy the unit-test. Once the test is passed and the code refactored, the programmer can go ahead with making further improvements. Test-driven development makes sure that the code is thoroughly tested which leads to a modularized, extensible, and flexible code. Each time a new feature is to be added, it needs to undergo what is called the “lifecycle” of TDD. Let’s talk more about this lifecycle. Check out upGrad’s Advanced Certification in DevOps How to Become a Full Stack Developer Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Test-Driven Development Lifecycle The test-driven development lifecycle covers everything from writing the initial unit-test to reworking the code. Add a test: Every new feature needs to undergo a test before its implemented. The essential requirement for writing a test is to have a clear understanding of all the requirements. This is accomplished using use-cases and user-stories.   Run all tests and check the net test: This is done to ensure the correct working of our test. Basically, this phase aims to check that the test is not passed by any code that doesn’t meet the requirements. By doing so, this step eliminates the possibility of having a faulty test at hand.   Write code: Now that you have your test in place, the next obvious step is to write a code that clears the test. This code need not be perfect in all aspects, but it needs to clear the test. Once we’re sure this code clears the test, it can be modified as per the requirements.   Run the tests: Having written the code, now it’s time to see if the code passes the test or not. If your code passes the tests, it means that your code meets the requirements – till now.   Refactor the code: This is essentially done to clean up the code. Refactoring doesn’t cause damage to any of the functionalities; it is just for cleaning the code by removing duplication between test code and production code.   Repeat: This cycle is now repeated with a fresh test to add more functionalities. Each functionality undergoes the same cycle. Essentially, the size of steps should be not more than 1-10 edits between each test run. If a code doesn’t pass the test rapidly, the developer must revert and not debug excessively.

However, it’s not infallible. Just like any other technology, the test-driven development also has a set of cons. Let’s have a look at what are the benefits of TDD in detail: Writing small tests ensures modularity of your code. Practicing TDD helps you understand the underlying principles of good modular design.   TDD provides clarity during the implementation of your code which enables a safety-net during the refactoring phase.   With TDD, collaborating is a lot easier as now people can edit the code with confidence because the test will inform them if their changes are not up to the mark of the test.   The base of TDD is unit-tests. Because of that, refactoring is a whole lot easier and faster. Refactoring an old code is a pain, but if the code is backed by unit tests, it becomes so much easier.   It helps in clarifying all the requirements before you begin the coding part. This way, a lot of ambiguity that can arise later on is avoided.   Test-driven development focuses on testing while writing. This forces the programmer to make their interfaces clean enough to pass the test. It’s hard to understand this advantage until you work on a piece of code that hasn’t undergone TDD.   Silly mistakes are caught almost immediately. It helps in removal of those mistakes that would waste a lot of time if found in QA.

Writing good unit tests requires a level of specialty.   It’s difficult to apply this approach to your legacy(existing) code.   TDD requires you to perform routine housekeeping. It’s necessary to refine the tests to make them run more quickly.   It’s easy to get distracted by the fancy features in any unit-testing framework, but it should be kept in mind that simple tests tend to give the best results.   Unless everyone on the team correctly maintains their tests, the whole system can quickly degrade.

A Beginner’s Guide to MVC Architecture in Java

If you’re related to web development scene, you’ll most certainly have come across the acronym “MVC” hundreds of time, if not more. MVC is one of the most talked about design patterns in the web programming world today, and rightly so. In this article, we’ll take you through the world of MVC Architecture. We’ll talk about the basics of MVC, its advantages, and finally, a simple code that will help you understand the implementation of MVC in Java in a clearer way. What exactly is the MVC architecture? Before we get into the technicalities of it, let’s make some things clear – MVC is NOT a design pattern, it’s a way to structure your applications. In recent years, the web applications are extensively using the MVC architecture, and hence it’s natural to confuse it for a design pattern exclusive for web applications. However, let’s tell you that MVC was first described way back in 1979 – before the WWW era when there was no concept of web applications. The architecture used today for web applications is an adaptation of the original pattern. In fact, this architecture was initially included in the two major web development frameworks – Struts and Ruby on Rails. These two environments paved the way for a majority of web frameworks that came later – and thus the popularity of this architecture kept rising. Learn to build applications like Swiggy, Quora, IMDB and more MVC architectural pattern follows an elementary idea – we must separate the responsibilities in any application on the following basis: Model: Handles data and business logic. View: Presents the data to the user whenever asked for. Controller: Entertains user requests and fetch necessary resources. Each of the components has a demarcated set of tasks which ensures smooth functioning of the entire application along with complete modularity. Let us have a look at each of these components in further detail. Check out our free courses to get an edge over the competition. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript upGrad’s Exclusive Software and Tech Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   Controller The controller is the like the housekeeper of the application – it performs coordination between model and view to entertain a user request. The user requests are received as HTTP get or post request – for example, when the user clicks on any GUI elements to perform any action. The primary function of a controller is to call and coordinate with the model to fetch any necessary resources required to act. Usually, on receiving a user request, the controller calls the appropriate model for the task at hand. Check out upGrad’s Full Stack Development Bootcamp (JS/MERN) Model The model is quite simply the data for our application. The data is “modelled” in a way it’s easy to store, retrieve, and edit. The model is how we apply rules to our data, which eventually represents the concepts our application manages. For any software application, everything is modelled as data that can be handled easily. What is a user, a book, or a message for an app? Nothing really, only data that must be processed according to specific rules. Like, the date must not be higher than the current date, the email must be in the correct format, the name mustn’t be more than “x” characters long, etc. Check out upGrad’s Java Bootcamp Whenever a user makes any request from the controller, it contacts the appropriate model which returns a data representation of whatever the user requested. This model will be the same for a particular work, irrespective of how we wish to display it to the user. That is why we can choose any available view to render the model data. Additionally, a model also contains the logic to update the relevant controller whenever there is any change in the model’s data. Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses View As the name suggests, the view is responsible for rendering the data received from the model. There may be pre-designed templates where you can fit the data, and there may even be several different views per model depending on the requirements. Any web application is structured keeping these three core components in mind. There may be a primary controller that is responsible for receiving all the requests and calling the specific controller for specific actions. Let’s understand the working of a web application under the MVC architecture better using an example. Let’s See an Example Let’s take an example of an online stationery shop. The user can view items, buy, add items to cart, add items to current order, or even add/remove items (if he’s the admin). Now, let’s see what will happen when a user clicks on the title “Pens” to see the list of pens. Our application will have a particular controller to handle all the queries related to pens. Let’s say it’s called “pens_controller.php”. We’ll also have a model that will store the data regarding the pens we have – let’s call it “pens_model.php”. Finally, we’ll have several views to present the data – a list of pens, a table displaying pens, a page to edit the list, etc. The following figure shows the complete flow of control right from the moment a user clicks on “pens”, to when the result is rendered in front of him: First, the “pens_controller.php” handles the user request (1) as a GET or POST request. We can also have an “index.php” which is the central controller which will call the “pens_controller” whenever needed. The controller then examines the request and the parameters and calls the required model – in this case, “pens_model.php”. The controller asks the model to return the list of available pens (2). Now, the model searches the database for the necessary information (3), applies logics if necessary, and returns the data to the controller(4). The controller then picks an appropriate view (5) and presents the data (6 and 7). If a request comes from a handheld device, a view suitable for it will be used, or if the user has a particular theme selected, its view will be picked – and so on. How to Become a Full Stack Developer The Advantages of the MVC Architecture A common problem faced by application developers these days is the support for different type of devices. The MVC architecture solves this problem as developers can create different interfaces for different devices, and based on from which device the request is made, the controller will select an appropriate view. The model sends the same data irrespective of the device being used, which ensures a complete consistency across all devices. The MVC separation beautifully isolates the view from the business logic. It also reduces complexities in designing large application by keeping the code and workflow structured. This makes the overall code much easier to maintain, test, debug, and reuse. In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses A Simple Implementation of MVC using Java We will have the following three: StudentObject : the model.   StudentView: view class to print details on the console.   StudentController: a controller that stores data in studentObject and updates StudentView accordingly Step 1: Create the Model public class Student {   private String rollNo;   private String name;      public String getRollNo() {      return rollNo;   }      public void setRollNo(String rollNo) {      this.rollNo = rollNo;   }      public String getName() {      return name;   }      public void setName(String name) {      this.name = name;   } } The code is self-explanatory. It consists of functions to get/set roll number and names of the students. Let’s call it “student.java”. Step 2: Create the View public class StudentView {   public void printStudentDetails(String studentName, String studentRollNo){      System.out.println("Student: ");      System.out.println("Name: " + studentName);      System.out.println("Roll No: " + studentRollNo);   } } This is simply to print the values to the console. Let’s call this “studentView.java”. Step 3: Create the Controller public class StudentController {   private Student model;   private StudentView view;   public StudentController(Student model, StudentView view){      this.model = model;      this.view = view;   }   public void setStudentName(String name){      model.setName(name);   }   public String getStudentName(){      return model.getName();   }   public void setStudentRollNo(String rollNo){      model.setRollNo(rollNo);   }   public String getStudentRollNo(){      return model.getRollNo();   }   public void updateView(){      view.printStudentDetails(model.getName(), model.getRollNo());   } } Call this “StudentController.java”. A cursory glance will tell you that this controller is just responsible for calling the model to get/set the data, and then updating the view. Now, let’s have a look at how all of this is tied together. Step 4: Create the main Java file public class MVCPatternDemo {   public static void main(String[] args) {      //fetch student record based on his roll no from the database      Student model  = retriveStudentFromDatabase();      //Create a view : to write student details on console      StudentView view = new StudentView();      StudentController controller = new StudentController(model, view);      controller.updateView();      //update model data      controller.setStudentName("John");      controller.updateView();   }   private static Student retriveStudentFromDatabase(){      Student student = new Student();      student.setName("Robert");      student.setRollNo("10");      return student;   } } This is called “MVCPatternDemo.java”. As you can see, it fetches the student data from the database or a function (in this case we’re using a function to set the values) and pushes it on to the Student model. Then, it initialises the view we had created earlier. Further, it also initialises our controller and binds it to the model and the view. The updateView() method is a part of the controller which updates the student details on the console. Step 5: Test the Result If everything goes right, the result should be: Student: Name: Robert Roll No: 10 Student: Name: John Roll No: 10 If you get this as the output, congratulations! You’ve successfully implemented the MVC architecture using Java, albeit for a simple application. However simple, this application is enough to demonstrate the powers of the MVC architecture. 15 Must-Know Spring MVC Interview Questions Wrapping Up… After so much said and done, it’s hard to emphasise more on the power of the MVC architecture in any web/desktop application these days. It provides an altogether new level of modularity to your code which makes it a lot more readable and maintainable. So, if you want to scale to new heights in your career as an application developer, getting hold of the MVC architecture and its working should be your top priority.

What is the Future Scope of Full Stack Developer in India?

Choosing a career in the tech sector can be tricky. You wouldn’t want to choose something that’s getting obsolete. You would want to find a career option that’s in demand and will remain in demand for the coming years. With so many options available, figuring out which one to choose can also be overwhelming. One of those options is full-stack development.  Full-stack developers are experts who are familiar with both client-side and server-side programming. They perform the roles of front-end and back-end developers. While some may argue that they are no specialists, a talented full-stack developer wouldn’t have much trouble handling development projects.  But you might wonder, “What is full stack developer’s future scope?” We’ll answer that question in this article and help you understand how attractive this field is. Let’s dive in.  Check out our free courses to get an edge over the competition. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript How Full Stack Development has Evolved You might think that full-stack development is a new term, but the concept has existed for a long time. Full-stack development has a fascinating history that goes back to the earliest days of programming. Knowing how much this field has evolved will let you get an idea of how much scope is there.  Since the beginning of software development, when there was no web or mobile programming, the role of full-stack developers has been present. In the early 80s, most of the software developers used to work alone and oversee the entire project from start to finish. Check out upGrad’s Full Stack Development Bootcamp (JS/MERN) There wasn’t much requirement of separate experts. Then the web came, and the need for specialists increased. As websites got more complex, the division between specialists also became distinct.  Things were this way in the 90s and remained this way until the mid-2000s. The term full-stack developer was coined much later, in the 2000s, when the web required the expertise of different expertise. Web applications required people to learn both client-side programming and server-side programming. And when people who studied both of these sectors entered the market, the term full stack developer arrived. Apart from that, tools and technologies that simplified the integration of client-side and server-side programming had entered the market. This helped the growth of full-stack developers.  Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Full Stack Scope Now Nowadays, full-stack development is in huge demand. Companies need full stack developers because of several reasons. Full-stack developers can work with multiple technologies, and so, they can handle more aspects of a project than an average programmer. Check out upGrad’s Advanced Certification in Cyber Security They cut costs for companies because they can do the work of many specialists alone. A full-stack developer is familiar with many stacks, including the MEAN stack and the LAMP stack. Their vast knowledge of multiple areas equips them to handle the unique requirements of their projects.  The average salary for full-stack developers in India is about 6.3 LPA, and it goes up to 16 LPA for experts. Companies are willing to pay handsome salaries to full-stack developers because of their unique skill sets and abilities. As a full-stack developer, you’ll have to handle both the client-side and the server-side of the application you develop. Read a detailed article about the full stack developers salary in India based on various factors. Huge Demand and Steady Growth The future of full-stack development is attractive. It looks promising because of the steady growth in demand of these professionals. There are many reasons why the demand for full-stack developers is increasing and will keep rising in the coming years. Here are some of those reasons: Smaller Teams With a full-stack developer in the team, you can keep the team short. And smaller teams have many advantages over large ones. Even Jeff Bezos believes that a small team is better than a large staff. A large team requires more communication and more resources. A large team costs more than a small group as well. As they require more communication, the chances of facing problems of miscommunication are also higher in their cases.  A full-stack developer can easily handle the work of 2-3 developers because of his/her expertise. An excellent full-stack developer can handle the requirements of both a front-end developer and a back-end developer. Due to this reason, a company can keep the teams small, avoid miscommunication, and reduce the operating costs.

Nagios has many features.  – Its APIs enable it for monitoring various systems, infrastructures, and applications. – It has add-ons that make you aware of the aging infrastructure and help you in planning upgrades. – You have full access to its code as it is open-source software.  – Its reporting system is fast and agile. It gives you a record of all the alerts and their responses.  – You can view the entire infrastructure of your organization through Nagios while also seeing the detailed information about everything. – Nagios has a vast community of more than a million users. If you come across any problems or have any questions, you can ask them who’d be happy to help.  How does Nagios operate? You can give this explanation as to your answer: Nagios runs as a service on a server It runs plugins on the server which connect with hosts on the network You can see the detailed information of the connected host through its interface In case some issue arises, you would receive an email or another notification Nagios runs scripts at specific times and saves the results of those scripts If the results of running the scripts change, Nagios starts running other scripts  That is how Nagios operates.  What do you mean by ‘Plugins’ in Nagios? Plugins in Nagios are different scripts that check the status of a service or host. You’d run them from the command line. Nagios checks the results from its plugins to see the condition of the various hosts and services present in your network.  You can also explain why plugins are necessary for Nagios.  Nagios requires plugins to check the status of the numerous hosts and services present in a network. A plugin verifies the required host and sends the results of its check to Nagios. Nagios then processes the results and determines whether an action is needed or not.  In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses What is NRPE? NRPE enables you to run plugins on remote Unix and Linux machines. This way, Nagios can monitor local resources such as memory usage and CPU on remote components. Typically, these resources are not given to remote machines; that’s why you’d need to use NRPE.  You can also give an explanation of NRPE architecture for a more detailed answer.  NRPE contains two sections, the NRPE daemon, and the check_NRPE plugin. The former runs on a different computer while the latter remains in the local machine and has an SSL connection between the monitoring machine and the remote machine.  What is a Passive Check?  In Nagios, external processes initiate Passive checks. When they are completed, the results are sent to Nagios. Passive checks help in monitoring asynchronous services. Those services can’t be tracked without regular polling of their status. Passive checks also help Nagios in checking the status of hosts that are behind a firewall as they can’t be verified through a monitoring host.  What are the advantages of using Nagios? Nagios offers plenty of advantages to an organization.  It allows you to plan future upgrades for your existing infrastructure It ensures a technical error in your IT infrastructure has minimum impact It quickly alerts you of any new problems It allows you to monitor the entire system and infrastructure  It coordinates the responses of the technical staff It helps you find out how fast your team responds to technical problems It ensures that SLAs (Service-Level Agreements) of your organization are met What is Icinga? How is it related to Nagios? Icinga is another popular open-source software that helps in monitoring services. It was designed in 2009 to help Nagios, but it has become a separate software.  What is an Active Check? Nagios performs an Active check to poll a device or service for its status information on a scheduled basis.  Can you name a few databases which support Nagios? Many databases support Nagios. They are Oracle, Postgres, Microsoft SQL solutions, and MySQL.  What is Nagios XI? Nagios is the most trusted and most powerful monitoring software. It can help you in monitoring applications, network protocols, systems, services, and metrics. It provides you with all the advantages of Nagios (discussed above) and has a powerful performance.  Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Is Nagios used to monitor window machines? Yes, Nagios is used to monitor window machines. You can do so by setting-up Nagios for monitoring the required window system and then add a separate server and host for performing the task.  What is OID Nagios? The Simple Network Management Protocol (aka SNMP) uses Object Identifiers for defining the Management Information Base.  What is the Nagios Network Analyzer? The network analyzer is a vital component of Nagios which checks the system for potential dangers. Its quick scan enables the admin to get the required data about the health of the system.  What are the benefits of using Nagios to monitor websites? Nagios can help you monitor websites too. It improves the website’s availability, helps you spot bugs, and you can enhance your site’s performance and avoid online security threats as well with the help of Nagios.  Is Nagios Object-oriented? If so, can you elaborate on what it means? Object-oriented means that you can produce object definitions in Nagios that are inherited from other objects.

All elements related to the alerting logic and the monitoring process are objects in Nagios.  Name three virtualization platforms that support Nagios. Microsoft Virtual PC, Amazon EC2, and VMware are three of the most popular virtualization platforms supporting Nagios.  What are the object types in Nagios? Nagios has a variety of object types such as host groups, periods, services, hosts, contact, notifications, and commands.  What are the two-state types in Nagios? Soft states and hard states are the two primary state types in Nagios.  Which database format does Nagios support for storing data? Nagios supports the RRD database format for storing status data.  What are the sections of NDO utilities? NDO utilities include FILE2STOCK Utility, NDOMOD Event Broker Module, NDO2DB Daemon, and LOG2NDO Utility.  What are the default credentials in Nagios? The Username and Password are “nagiosadmin” in Nagios as default.  What language does Nagios core use? Nagios core uses PHP and CGI.  What are the required conditions for Nagios to check external commands? Nagios checks for external commands regularly according to the command_check_interval option. In addition to the regular checks, it also checks for external commands when an event handler is executed.  What are the differences between Passive and Active checks? It is one of the most popular Nagios interview questions, so we suggest you prepare the answer thoroughly.  The main difference between Active checks and Passive checks is that Nagios performs the former while an external application performs the latter.  Passive checks monitor services that are located behind a firewall or are asynchronous. Active tests can’t be done on those services or hosts even though Nagios performs them regularly.  How is Nagios related to DevOps? Continuous monitoring is a core component of DevOps and Nagios is a popular tool for the same.  Can you customize charts in Nagios? Yes, you can customize charts through a third-party tool such as Graphite or CACTI. What is the difference between soft and hard states in Nagios? To answer this question, you should define both of these states.  When the results of a host or service are not OK, but it has not been rechecked multiple times according to max_check_attempts, then the error is specified as a Soft error. When a host or service recovers from a Soft Error, it is called Soft Recovery. On the other hand, when the results of a host or service check are not OK even when they have been rechecked several times, according to max_check_attempts, the error is called Hard Error. Recovery from such a kind of error is called Hard Recovery.  upGrad’s Exclusive Software Development Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   Which three variables affect inheritance and recursion in Nagios? The three variables affecting recursion and inheritance are Name, Use, and Register. The name is a placeholder for other objects. Use specifies the parent object and Register can either have a value of 1 or 0. If the Register has a value of 1, it means it’s an actual object. If it has a value of 0, it means the object is only a template and isn’t a real object.  What is meant by State Stalking? Let us discuss what State Stalking is. State stalking helps in logging. With State Stalking, Nagios watches a particular service or host and log any changes it notices in the check results. You can also add that State Stalking is quite helpful in the analysis of logs. Without State Stalking, Nagios logs a check only when the state is changed between two checks.  What is Flap Detection in Nagios? When a host or service changes its state too frequently, it is called Flapping. Flapping can lead to many problems, which could, in turn, cause many recovery notifications to arise. Nagios checks if a service or host has started flapping during its status check.  Nagios checks for flapping. It does so by storing the results of the previous 21 checks of the specific service or host first. And it analyzes those results to see how frequent state changes occurred. It determines a percent state change value through that data and compares the same to flapping thresholds. When the percent state change is greater than the high threshold for flapping, the object is said to have started flapping. And when the percent state change is lower than the low threshold for flapping the object is said to have stopped flapping.  How would you explain the ‘Machine is Unreachable’ error? When Nagios fails in finding a path to a specific node, it shows this error. The node might be up, but because Nagios can’t access it, it shows the node as unreachable.  Final Thoughts We hope you found these Nagios interview questions helpful.

Continuous Delivery vs. Continuous Deployment: Difference Between

Knowing the difference between continuous delivery vs continuous deployment is paramount in today’s rapidly progressing world. That is because your users should be able to update the software without much hassle.  It is something that you are aware of through your smartphone, laptop, or computer software. Software updates for a wide range of applications are a regular occurrence. Without them happening, developments cannot take place.  Check out our free courses to get an edge over the competition. So, what can you do about it? In this internet era, you should be able to meet your user’s requirements in a matter of time. When you rectify errors or issues quickly, you can retain your clients. At the same time, when you find it challenging to do so, it can cause drowning profits.  So, when you opt for the usual slow and obsolete process of finding, analyzing, and planning methods, you are well out of the market. You have lost the plot altogether. To avoid being left out in the lurch, what you require is agile development.  Check out upGrad’s Advanced Certification in Cyber Security  Opt for agile development Agile development is the process or framework where you can test, plan, and eventually implement your ideas. The best part is that you can do it immediately. Instant results are the order of the day.  Those businesses and companies that have embedded agile development into their processing plans stand to gain from it. When you can achieve continuous delivery as well as constant deployment in your solution delivery pipeline, your firm can release the updates efficiently.  For our readers, who are not aware of the difference between continuous delivery and continuous deployment, then we will try and clarify through this post. Not to mention, you will also learn how they fit into an agile environment.  When you want to understand both continuous delivery and continuous deployment, then you must first understand, continuous integration.  Check out upGrad’s Advanced Certification in Cloud Computing  It is an essential element for agile practice.  An Agile Developer knows the significance of implementing this process because it gives them the ability to manage smaller components. This way, they can design quality software. For agile concepts, all the teams know what is going on, unlike the waterfall concept.  Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Developers must use deployment automation tool        That is why developers must consider using automation of continuous deployment at the development stage itself. Solutions should be given to ensure that continuous integration and continuous delivery are smoothly handled through a consumption-based model. What is continuous integration? Continuous integration is a process where, several methodologies are used from several sources, automatically to integrate the code for designing and testing purposes. As a DevOps Developer, when your design code can pass the test, then it is deployed automatically.  Further testing is then conducted on your code like manual exploratory test and load test. You would be surprised to know that the process can take several days. It entirely depends on the requirements.  What is continuous delivery? Continuous delivery enables you to design a high-quality version of your code. This classic version helps you to decide when you want to release your software for your clients, based on the feedback. In most cases, the timing of the release matters depending on the market condition.  Continuous delivery vs. continuous deployment It is the main difference between continuous delivery vs continuous deployment. Continuous deployment is the process where the software to be released undergoes an automated pipeline. Developers need not worry about the release, but rather ensure that the code developed, is regularly tested, updated, and then released. More importantly, it must work fine from the client’s end.  The continuous delivery consists of a time lag before the release of the software. The product gets reviewed, and changes, if any, is done before the release. Continuous deployment involves automated testing throughout the entire process until the release of the product.  Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript How can you consolidate delivery and deployment to attain common goals? It is when some developers get tempted to think that continuous deployment may be advantageous for the software. It depends on the CI/CD practices implemented in your organization.  However, there are some constraints that you might want to beware of before making use of continuous deployment. Market conditions and regulatory compliances, usually restrict IT firms from making use of continuous deployment. The levels of the DevOps concepts implemented in an IT firm also dramatically influences the usage of continuous deployment.  Continuous delivery requires manual code changes, and that can delay in the deadline for deploying the code.  But, there are some benefits to using it. IT firms may want to consider using continuous delivery because of the convenience. It enables IT firms to have a competitive advantage for deploying the code, ably supported by human intelligence.  Developers can come up with many new features that can be designed and ready for implementation. It enables them to develop robust and resilient systems. What this does is, reduces the production costs, and allows developers to improve the quality of the product.  But, continuous delivery and continuous deployment may not be that relevant in some areas of work. You may not require a deployment phase when contributing to a library or designing an artifact.

These days, there is a new development for designing high-end tools for application release that can effectively manage software releases. Few of them include: Packaging of the applications  The version of the release  When updating the database  Managing the configuration of the server  Rollback and roll forward  Auditing and access for security purposes To summarise, the main difference between continuous delivery vs continuous deployment would be that continuous delivery is the ability to release a version on any platform. On the other hand, continuous deployment is your ability to deploy the versions continuously.  Both the concepts need a framework, where you can work on small, but effective changes that can be implemented immediately in the market. It would help if you learned how your updates had affected the users, in a good and bad way.  You will need to communicate with your clients to achieve what you intend to by finding out how it helped or did not help them. However, to make that, you need to bring value to your users.  upGrad’s Exclusive Software Development Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   Do you want to learn more?
