Explain the purpose of ExpressJS package?

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

Express is a light-weight web application framework to help organize our web application into a MVC architecture on the server side. We can use a variety of choices for your templating language like EJS, Jade.

Express.js basically helps you manage everything, from routes, to handling requests, response and views. An example of an Express.js routing is as follow:

var express = require('express')
var app = express()

// respond with "hello world" when a GET request is made to the homepage
app.get('/', function (req, res) {
  res.send('hello world')
})


Express.js is a framework built on top of Node.js that facilitates the management of the flow of data between server and routes in the server-side applications.

It is a lightweight and flexible framework that provides a wide range of features required for the web as well as mobile application development.

Express.js is developed on the middleware module of Node.js called connect. The connect module further makes use of http module to communicate with Node.js. Thus, if you are working with any of the connect based middleware modules, then you can easily integrate with Express.js.
