Route

route

• create a folder in the root directory /src/route
• under this folder, create a file called todos.js

const express = require('express');
const router = express.Router();    //in each route, we cannot use app, but we use router object

router.get('/', (req,res)=>{
  res.send('show all todos');
})

module.exports = router;

use route

• in app.js, now we can import and use this route

//use routes
const bootcamps = require('./src/routes/todos');
app.use('/todos',todos);
