Node.js Courses

Node.js is an open-source, back-end JavaScript environment that relies on the V8 engine (an engine developed for Chromium web browsers and Google Chrome) to execute code outside browsers. Developers can use JavaScript for server-side scripting and code command lines. It helps create networking tools and Web Servers using JavaScript. It is supported on Microsoft Windows 8.1, macOS, and Linux.

As Node.js helps create scalable tools and networks, it seems appealing to enterprise owners. It is a high-performance, super-fast, and lightweight web development framework that lets developers perform asynchronous programming. With this, developers are free to execute numerous actions simultaneously, a perk of being a serverless platform.

Node.js is known for its better scalability, optimized costs, and enhanced performance.

A team of web development experts can save a lot of time using ready-to-run and reusable node module components. However, it may not be the most sought-after platform or framework for all, but it has left behind other frameworks in terms of web traffic (for which everyone website owner cares). According to web technology survey reports, high-traffic websites use Node.js rather than other web development platforms such as Apache, Nginx, Microsoft IIS, Cloudflare server, and Lightspeed.

Node.js is one of the most suitable platforms for web development due to its flexibility and versatility. Further, it comes with different uses that most platforms do not offer.

Here are some of its popular uses.

• Browser Games- Browser games are one of the most exciting applications or outcomes of the real-time web. With these, players don't need to use complex programs such as Shockwave applet, JAVA, or Flash to play games. The games work efficiently in their browsers. Combining Node.js with HTML5 and Socket.io can create more impressive and rich browser games. Multiplayer games are also made using the same technology.
• Chat Rooms- These days, people use chatting platforms or social media to connect with friends or family. Keeping this in mind, developers use Node.js to create well-working chat rooms. In online games, independent chat rooms double the fun.
• Data Collection- Node.js can help collect large amounts of data efficiently. Massive information forms a bottleneck in a database as it is a blocked operation. Node, on the contrary, gets this data and sends it in form pieces to the backend. It ensures that data transfer takes place without damaging the system.
• MEAN Stack- The MEAN Stack is developed using JavaScript; hence worth some space here. MEAN Stack makes web development simple for a developer and also easy on the device. It can be combined with other modules too. For instance, Mongoose integrated with Node.js results in MongoDB. Interestingly, the letter N in the MEAN stands for Node.js.

Streaming- Many audio or video content files are uploaded on streaming platforms such as Facebook, Instagram, and Youtube. But they need to be processed to be available for viewers. The processing starts when it has been uploaded on the web. However, using Node.js, they can be processed and uploaded simultaneously. This publishes content fast and saves time.

As we know, Node.js is an open-source backend JavaScript environment where the JavaScript (JS) works on the server-side of the application. Because of this, JavaScript is used on both the Backend and Frontend.

Node.js applies to the chrome v8 engine, which converts JavaScript code into machine code.

Node.js working- Node uses the concept of threads while operating requests. It receives requests from the client-side and delivers the response. During this process, it handles the requests using a single thread. It works parallel and along the server to provide information to the clients. Node.js is considered a single-threaded event loop language as it can manage repetitive requests using a single thread without blocking it for a single request.

Node.js Working depends on two concepts:

Non-blocking I/O – This concept generally shows the working of Node.js with several requests without blocking one request thread. The I/O system communicates with external systems like databases and files. Node is not meant for video processing or calculations as a single thread cannot handle the work of the CPU.

Asynchronous – This concept means executing a call-back function. Node.js runs a call-back function when it receives responses from other databases or servers. These functions are executed when the work is completed. The reason is that Node.js uses an event-based architecture. A single thread sends a request to other systems, resolves it, and is available to take additional requests.
