server.js

// ==============================================================================
// DEPENDENCIES
// Series of npm packages that we will use to give our server useful functionality
// ==============================================================================
var express = require("express");
var bodyParser = require("body-parser");
var handleBars = require('handlebars');
var exphbs = require("express-handlebars");

//Note that the mysql dependency handled in the database layer

// ==============================================================================
// EXPRESS CONFIGURATION
// This sets up the basic properties for our express server
// ==============================================================================

// Tells node that we are creating an "express" server
var app = express();

//Static directory to serve css etc
app.use(express.static('public'));



// Sets up the Express app to handle data parsing
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json({type:'application/vnd.api+json'}));


// ================================================================================
// Handlebars
// Templating Functions will be handled by handlebars
// I thought this was similar to Razor, but razor is really a scripting languate
// handleBards is really a template.  Comparable (a little) to partialViews
// But not really :-(
// ================================================================================
app.engine("handlebars", exphbs({ defaultLayout: "main" }));
app.set("view engine", "handlebars");



// ================================================================================
// ROUTER
// The below points our server to a series of "route" files.
// These routes give our server a "map" of how to respond when users visit or request data from various URLs.
// ================================================================================
var routes = require("./controllers/burgers_controller.js");
app.use(routes);


// =============================================================================
// LISTENER
// The below code effectively "starts" our server
// =============================================================================

// Sets an initial port. We"ll use this later in our listener
var PORT = process.env.PORT || 8082;

app.listen(PORT, function() {
  console.log("App listening on PORT: " + PORT);
});
