.route express code example

Example 1: express route parameters

app.get('/users/:userId/books/:bookId', function (req, res) {
  res.send(req.params)
})

Example 2: nodejs express routing

// You need to install the following packages
npm install --save mysql express
// And if you don't want to restart your server after every little change
npm install -g nodemon

Example 3: express() vs express.router()

var express = require('express');

var router = express.Router();

router.get('/', function(req, res) {
    res.send('GET handler for /dogs route.');
});

router.post('/', function(req, res) {
    res.send('POST handler for /dogs route.');
});

module.exports = router;
