Lecture 285:- Setup the Express Router

As per the prompt, I assume that you are looking for help in setting up the Express Router. Here are the steps to set up the Express Router:

1. First, require the Express Router in your app.js file:

javascriptCopy code

const express = require('express'); const app = express(); const router = express.Router();

1. Next, define a route with the router:

javascriptCopy code

router.get('/', (req, res) => {  res.send('Hello World'); });

This defines a route for the home page ('/') and sends the response 'Hello World'.

1. Mount the router middleware in your application:

javascriptCopy code

app.use('/', router);

This tells Express to use the router middleware for all requests starting with /.

1. Finally, start the server:

javascriptCopy code

app.listen(3000, () => {  console.log('Server listening on port 3000'); });

This starts the server and listens for requests on port 3000.

With these steps, you have set up the Express Router in your application. You can define more routes in the same way by adding new routes to the router and mounting it using app.use().
