Understand Express JS in Just Half a Minute! #expressjs #quickguide

Express JS is a fast, unopinionated, minimalist web framework for Node.js. It allows you to build web applications and APIs quickly and easily.

To get started with Express, first install it using npm:

npm install express

Then, create a new Express app in a JavaScript file:

const express = require(‘express’);
const app = express();

Next, define routes for your app using HTTP methods like GET, POST, PUT, and DELETE:

app.get(‘/’, (req, res) => {
res.send(‘Hello World!’);
});

Finally, start your Express server:

app.listen(3000, () => {
console.log(‘Server is running on port 3000’);
});

That’s it! You now have a basic Express app up and running. You can further customize your app with middleware, routers, and other features provided by Express to build powerful web applications. Express is a popular choice for building web applications due to its simplicity, flexibility, and robustness.
