Node.JS Server on Ubuntu Server 20.04

Node.js® is a JavaScript runtime built on Chromes V8 JavaScript engine. As an asynchronous event-driven JavaScript runtime, Nodejs is designed to build scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

NodeJS Features:

• 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 Chromes V8 JavaScript Engine, Nodejs 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.
