How do I set up routing in an Express.js API?

To set up routing in an Express.js API, you can use the express.Router() class to create modular route handlers.

Can you show me a basic example of using express.Router()?

Sure! Here's a simple example:

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

router.get('/users', (req, res) => {
    res.send('User list');
});

module.exports = router;

How do I integrate this router into my main app?

You can integrate it by requiring the router in your main app file and using it with app.use(). For example:

const usersRouter = require('./users');
app.use('/api', usersRouter);
