A BRIEF INTRODUCTION

Node Runtime Environment

Node.js is an asynchronous event-driven JavaScript runtime (based on Chrome's V8) which 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.

Node.js is open source, works cross-platform and is usually used for developing server-side and networking applications which are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux. It also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent.

Top companies using Node.js:

NODE.JS ONLINE COMPILER

Node.js in your Browser!

The purpose of Node.js is to enable the execution of javaScript outside the browser environment. However, many developers want to try-out/experiment with versions of Node which is a painfull process as different versions need to be installed locally and maintained.

Don't worry we've got your back! Using the online Node.js compiler you can quickly code, collaborate, compile, run & share NodeJS code for free. The Node.js online compiler by codedamn is robust and feature-rich, running the latest LTS version NodeJS v14. Getting started is easy and fast since the editor shows sample boilerplate code. Feel free to add any packages you like by using the yarn package manager in the integrated terminal. For example,

damner@codedamn:~/code$ yarn add express

What is happening under the hood?

V8 is an independent C++ library that is used by Node or Chromium to run JavaScript code. V8 exposes an API that other code can use, so if you have your own C++ program, you can embed V8 in it and run a JavaScript program. That is how it is done by Node.js produces an environment to execute javaScript code.

CODEDAMN ONLINE COMPILERS

Codedamn Node.js Compiler

The codedamn online compiler utilizes the power of cloud computing to give you a fast and reliable coding experience. When you boot the online python compiler, a docker container is started on a remote linux computer. This docker container is already setup with Node.js v14 which can run your javaScript and check for any errors or problems. As your code is executed, the output / errors will show up on the integrated terminal of the online Node.js compiler.

To serve HTML through your node server running on process.env.PUBLIC_PORT, change the Content-Type header

const server = http.createServer((req, res) => {
	res.statusCode = 200
-       res.setHeader('Content-Type', 'text/plain')
+       res.setHeader('Content-Type', 'text/html')
	res.end('Hello from codedamn!')
})

Then you can send HTML like so:

res.end(`
<!DOCTYPE html>
<html>
	<head>
		<style>
			h1 {
				color: blue;
				font-family: verdana;
				font-size: 300%;
			}
			p  {
				color: red;
				font-family: courier;
				font-size: 160%;
			}
		</style>
	</head>
	<body>
		<h1>Hello from NodeJS!</h1>
		<p>Hello from Codedamn!</p>
	</body>
</html>
`)

Now, to execute your node.js code simply start the server and refresh the browser preview

damner@codedamn:~/code$ node index.js
Server running at http://localhost:1337/

🚨 Pro Tip!

Start your node server with nodemon to avoid re-starting it everytime you make a change. Install nodemon using

damner@codedamn:~/code$ yarn add nodemon

Start your server like so

damner@codedamn:~/code$ nodemon ./index.js
