app.use(bodyParser.urlencoded({
    extended: true
}));
app.post('login', function(req, res) {
    var name = req.body.username;

const express = require('express');

const router = express.Router();

router.get('/', (req, res) => {

Here you just need to import routes and define middleware in your root file

Give your path of index.js file here I assume you have index.js file inside routes/index.js

const routes = require('./routes/index')

and use middleware like

app.use('/get', routes);

Now your URL looks like http://localhost:3000/get
