What is Express

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for building web and mobile applications. It facilitates the rapid development of Node-based web applications by providing a myriad of HTTP utility methods and middleware, making it easier to create APIs and handle requests and responses.

The framework is designed to be unopinionated, allowing developers to structure their applications in a way that suits their unique needs. This flexibility makes Express a popular choice among developers for creating RESTful APIs, single-page applications, and server-rendered websites.

Example of Express Application

const express = require('express'); const app = express(); app.get('/', (req, res) => { res.send('Hello World!'); }); app.listen(3000, () => { console.log('Server is running on port 3000'); });
