var express = require('express');
var app = express();

console.log("Registering endpoint: /");
app.get('/', function(req, res){
    res.send('hello ROOT world');
});

console.log("Registering endpoint: /stubbed");
app.get('/stubbed', function(req, res){
    res.send('hello STUBBED');
});

console.log("Registering endpoint: /testing");
app.get('/testing', function(req, res){
    res.send('this is a test endpoint');
});

console.log("Registering endpoint: /jsonendpoint");
app.get('/jsonendpoint', function(req, res){
    res.json({
        "mykey" : "myvalue", 
        "testy" : "something", 
        "exnum" : 123
    });
});

app.listen(3000);
