basic HTTP JSON server using NodeJS. Ideal for backend data test for mobile or web UI

router.js

var test = require('./test');

function route(pathname){

  var data;

	pathname = pathname.substring(1, pathname.length);
	switch(pathname){
		case "somethingrandom" :
				data = {
					'something random' : 'true',
					'something truly random' : 'true'
				};
				break;
		case "test" :
				data = test.returnSomeData();
				break;
		
		default:
				data = {'error' : 'incorrect endpoint'};

	}

	return data;

}

module.exports.route = route;

server.js

//server.js

var http = require('http');
var router = require('./router'); //router file


function processIncomingRequest(req, res){
  
	console.log("INCOMING REQUEST: "+req.method+ " "+ req.url);

	var response = router.route(req.url);

	res.writeHead(200,{
		'Content-Type' : 'application/json',
		'Content-Length' : response.length
	});

	res.end(JSON.stringify(response) + "\n");
}

var server= http.createServer(processIncomingRequest);
server.listen(8080);

test.js

function returnSomeData(){
  var jsonData = {
		'item-1' : 'a table',
		'item-2' : 'a phone',
		'item-3' : 'a coffee mug',
		'item-4' : 'a mouse device',
		'item-5' : 'a sunglass',
		'item-6' : 'a necktie',
	};

	return jsonData;
}

module.exports.returnSomeData = returnSomeData;

in the above code snippet, to use it as a backend REST Endpoint, following needs to be done:

//1. create a new js file with a function that returns the JSON Data (Similar to test.js) and dont forget to module export the method that returns the json data

//2. in router.js add another case with the endpoint as the evaluating expression (like for localhost:8080/newEndpoint) the evaluating expression will be newEndpoint. Also dont forget to include you new js file vai require statement

//3. inside the case (like test in router.js), call the new function and assign the returning JSON to the variable 'data'

Thats it! you are done!!
