To know if node is installed :

	node -v

Update modules using :

	npm install npm -g

Setting up a new project :

	npm init

This will make package.json, and make sure that index.js as the start point!

To make Node as a serverside framework, we have to use a web framework called Express.

To install Exrpess, simply type

	npm install express --save

It will show in package.json as a dependency.

It also helps to modularize the code and handle requests and responses.

An example of index.js will be

	var express = require('express');
	var app = express();
	
	app.use('/', (req, res) => {
			res.send('hello node');
	});
	
	app.listen(3000, () => {
			console.log('Listening on port 3000');
	});

By the way, require means that we are using the ‘express’ package.

Lastly, we just type

	node index.js

and we can see hello node in localhost::3000
