As a newfangled piece of technology, NodeJS is a cutting-edge web server that generates vast attention, not only from start-ups but also from giant enterprises. NodeJS is considered an exceptional framework for the IT market because of the following factors:
- NodeJS is an open source cross-platform that is built on the V8 JavaScript runtime of Chrome.
- NodeJS is ideal for data-intensive, real-time applications, and it enables event-driven programming.
- NodeJS is also a super-fast JavaScript interpreter because it works on a non-blocking I/O model.
- Outperforming conventional web servers, NodeJS has been a viable option for Yahoo, eBay, and Walmart.
- NodeJS employs push technology.
- It is also a lightweight web server in terms of memory usage.
- NodeJS can be a good solution for data-dense, real-time web applications across multiple devices.
The following features of NodeJS are usually emphasized by developers:
- The super-fast web server: NodeJS operates at a very high speed by using a single-threaded event loop model to process all of its asynchronous I/O operations. Therefore, any major actions can be performed quickly with NodeJS, such as network connections, filesystems, and reading/writing to databases. NodeJS supports developers by allowing them to create quick and robust network applications and offers parallel connections to increase throughput.
- The JavaScript web server: The NodeJS suite is a JavaScript runtime environment, and developers can now write JavaScript not only in the browser but also on the server. When the browser code and the server code are created in a similar manner, it is convenient to transport data between the server and the client. NodeJS fills the gap between the frontend and backend skills, and full stack developers can use JavaScript for both. The fact that all NodeJS programs are made using JavaScript increases the effectiveness of the web development process.
- Real-time data streaming: NodeJS considers both HTTP requests and responses as data streams. Hence, when data comes in the form of streams, the overall processing time can be reduced because NodeJS can process files and upload files at the same time. Developers can choose NodeJS for real-time video or audio recording.
- Real-time web applications: Because NodeJS is very fast, it is obviously a winner for games and chat apps as well as any other multi-user real-time web apps. The synchronization process is fast and orderly due to the event-driven architecture of NodeJS, and the event loop of NodeJS through the web socket protocol handles the multi-user function.
- Node Package Manager (NPM): NodeJS is an open source suite with more than 60,000 modules in the NPM.
- A good solution for synchronization: NodeJS is very efficient in its ability to solve common network development problems because it manages asynchronous I/O very well with its single-threaded event loop. In order to handle many clients, all I/O tasks are undertaken together in NodeJS.
