How to use Express JS Router In Express

Using Express JS

Through the Express JS Router, we will create a base URL, and then we can directly use the router to implement a nested URL through it. The express.Router() function is used to create a new router object. This function is used when you want to create a new router object in your program to handle requests.

Syntax:

express.Router( [options] )

Example: This example implements nested routing using Express JS Router

Javascript

// Server.js
const express = require('express');
const app = express();
const PORT = 3000;
const router = express.Router();
 
// Nested Route
router.get('/', (req, res) => {
    res.send("USER NESTED API IS Endpoint!");
})
 
// Another Nested Route
router.get('/api', (req, res) => {
    res.send("/API endpoint")
})
// Parent Route
app.use('/user', router);
app.listen(PORT, () => {
    console.log(`Server established at ${PORT}`);
})

Output:
