9. Explanation of Routes A router maps HTTP requests to a callback. HTTP requests can be sent as GET/POST/PUT/DELETE, etc. URLs describe the location targeted. Node helps you map a HTTP GET request like: –http://localhost:8888/index To a request handler (callback) app.get('/index', function (req, res) {});

10. Creating a Simple Express Application var express = require('express'); var app = express(); app.get('/', function (req, res) { res.json({message:'hooray! welcome to our api! '}); }); app.listen(process.env.PORT || 8080);
