Features of Node.Js

Features of Node.js

Following are some of the important features that make Node.js the first choice of software architects.

·        Asynchronous and Event Driven − All APIs of Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.

·        Very Fast − Being built on Google Chrome's V8 JavaScript Engine, Node.js library is very fast in code execution.

·        Single Threaded but Highly Scalable − Node.js uses a single threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server.

·        No Buffering − Node.js applications never buffer any data. These applications simply output the data in chunks.

·        License − Node.js is released under the MIT License
