The Importance of Node.js in the Responsive Web Era
Why Node.js is used widely by Modern Web Developers?
Asynchronous I/O Operations
Node.js further performs all I/O operations asynchronously through a single-treaded event look. The modern approach makes the Node.js application perform I/O operations by sending the asynchronous task to an event loop along with a call-back function. After sending the asynchronous task to the event loop, the application continues executing the remaining code. After completing the asynchronous operation, the event loop returns to the task, and executes the call-back function. In addition to consuming less memory, the feature enables Node.js to handle a large number of concurrent connections efficiently. The programmers can use the runtime environment to perform common tasks like reading or writing to the database, file system or network connections.
Complements Real-Time and Multi-User Requirements
In addition to using responsive web design, the developers nowadays need to build multi-user and real-time web applications. Node.js enables programmers to create complex gaming, chatting and communication applications without putting any extra time and effort. The developers can use websocket protocols to build real-time web applications. As a two-way communication channel between the client and web server, websockets can make the web server push data to the client in a faster and more efficient way without increasing the overhead of HTTP. At the same time, the developers can create multi-user applications by taking advantage of the even loop feature of Node.js.
Facilitates File Streaming
The web programmers can take advantage of the efficient I/O handling capacity to Node.js to reduce the amount of time required for streaming a file from the file system. They can use the runtime to read/write streams to both HTTP and websockets. Thus, they have can reduce the overall transcode audio or video processing time in a number of ways. For instance, a programmer can simply shift the stdout from the web server to a web browser through websockets, and allow the web page to display output to the user in real time.
