Include other files and call function from other class

Require another file 

Create a file called index.js and paste the following code

      var server = require("./server");

      server.start(router.route, handle);

Now create a new file name it server.js and paste the following code

      var http = require("http");

      var url = require("url");

      function start(route, handle) {

       function onRequest(request, response) {

        var pathname = url.parse(request.url).pathname;

        console.log("Request for  received.");

         }  

        http.createServer(onRequest).listen(8888);

       console.log("Server has started.");

       }

   exports.start = start;

Now run index.js

node index.js

The result wll be

"Server has started"

Now open your browser and type http://localhost:8888/

Now the server will respond with "Request for  received."
