NodeJs Javascript Server: an open source Javascript server

NodeJs (Node.js) is an open-source, cross-platform, server-side JavaScript runtime environment that runs on a JavaScript Engine (V8 engine) and executes JavaScript code outside a web browser, which was designed to build scalable network applications. NodeJs lets developers use JavaScript to write command line tools and for server-side scripting-running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, NodeJs represents a "JavaScript everywhere" paradigm, unifying web-application development around a single programming language, rather than different languages for server-side and client-side scripts.
Written in: C, C++, Javascript

Project Goals
  • NodeJs is primarily used for non-blocking, event-driven servers, due to its single-threaded nature
  • It's used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind
  • It does offer an asynchronous event-driven JavaScript server-side runtime
  • NodeJs is well suited for handling concurrent connections, making it an excellent framework to develop real-time as well as multi-user web apps
  • It doesn't support multi-threaded programming yet ; it is able to serve way more complicated applications than Ruby, but it's not suitable for performing long-running calculations or heavy load tasks
Project Features
  • Asynchronous and Event Driven
  • Single Threaded but Highly Scalable
  • No Buffering - NodeJs applications never buffer any data ; these applications simply output the data in chunks
  • Quick execution of code: Javascript is lighweight and fast
  • Cross-platform compatibility: NodeJS may be used on a variety of operating systems, being very portable
Project Design and Security
  • Very Fast, built on Google Chrome's V8 JavaScript Engine
  • Used for I/O bound Applications, Data Streaming Applications, Data Intensive Real-time Applications, JSON APIs based Applications, Single Page Applications
  • Code for large applications may be complex due to the asynchronous nature of NodeJs
  • New features are constantly being added to the V8 engine ; generally speaking, expect them to land on a future NodeJs release, although timing is unknown
  • NodeJs provides a simple way to list all dependencies and respective versions that ship with a specific binary through the process global object

Sample Configuration
// Once the NodeJs is installed, create a file named `app.js` containing the following code
// it will start a NodeJS sample app (Hello World) on port 8077 at
// to run this application type in a terminal: `node app.js` ; open in the browser:

const http = require('http');

const hostname = '';
const port = 8077;

const server = http.createServer((req, res) => {
	res.statusCode = 200;
	res.setHeader('Content-Type', 'text/plain');
	res.end('Hello World');

server.listen(port, hostname, () => {
	console.log(`Server running at http://${hostname}:${port}/`);
