In Node.js terms, a route is a binding between a URI and function. The Express framework provides built-in support for routing. An express object instance contains functions named after each HTTP verb: get, post, put, and delete. They have the following syntax: function(uri, handler);. They are used to bind a handler function to a specific HTTP action executed over a URI. The handler function usually takes two arguments: request and response. Let's see it with a simple Hello route application:
var express = require('express');
var app = express();
app.get('/hello', function(request, response){
response.send('Hello route');
});
app.listen(3000);
Running this sample at localhost and accessing http://localhost:3000/hello will result in calling your handler function and it will respond saying Hello route, but routing...
