How do I split up my routes using Express.Router() into multiple files?

Question

I am trying to figure out how to split the routes in my routes.js file into multiple files. My current routes.js file looks like this:

const pullController = require('./controllers/pullController');
const userController = require('./controllers/userController');

const routes = require('express').Router();
routes.get('/openpullinfo', pullController.getOpenPullRequestInfo);
.
.
.
routes.post('/user', userController.createUser);

module.exports = routes;

I want to have a different routes file (i.e. userRoutes.js) for each controller because there are just too many routes in my single routes.js file and it's becoming unmanageable.

You can create a set of routes file (userRoutes.js, pullRoutes.js...). In these files, you can use the express.Router class to create modular, mountable route handlers. Then in the main file, you mount all your routers in your Express application.

Example :

• userRoutes.js

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

router.get('/', function (req, res) {

    res.send('Get users controller');
});

router.post('/', function (req, res) {

    res.send('Post user controller');
});

module.exports = router;

• server.js

const express = require("express");
const app = express();

app.use(express.urlencoded())
app.use(express.json())


const userRoutes = require('./userRoutes');

app.use('/users', userRoutes);

app.listen(80);

In the browser, http://localhost/users gives me the text Get users controller
