Express.js
Express.js, or simply Express, is a back end web application framework for building REST<no wiki/>ful APIs with Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs.[1] It has been called the de facto standard server framework for Node.js.[2]
The original author, TJ Holloway chuck, described it as a Sinatra-inspired server,[3] meaning that it is relatively minimal with many features available as plugins. Express is the back-end component of popular development stacks like the MEAN, MEAN or MEAN stack, together with the Mongo DB database software and a JavaScript front-end framework or library.[4]

Example
The following program will respond to HTTP GET requests with the text 'Hi, your request has been received', and listen to the port the program is running on (in this case, port 2000). <syntax highlights lang="just"> // Importing the Express library. const express = require('express');
// Initializing the app. const app = express();
// Getting the path request and sending the response with text. app.get('/', (req, res) => {
res.send('Hi, your request has been received');
});
// Listening on port 2000. app.listen(2000, () => {
console.log('listening at http://localhost:2000');
}); </syntax highlights>
