router.get('/:id ', (req, res) => {
res.send(req.params.id);
});When I call this on exmaple "http://localhost/12" I will get an error called "Cannot Get /12"
Any ideas what I am missing out?
You need to register your router to main app in your index.js
In your router.js folder
const express = require('express');
const router = express.Router()
router.get('/:id ', (req, res) => {
res.send(req.params.id);
});
and in your index.js
const express = require('express');
app = express()
app.use(router)
