Module dependencies.

 
var

Built in modules

 
    http = require('http')
  , url = require('url')
  , querystring = require('querystring')
  , fs = require('fs')
  , spawn = require('child_process').spawn

My modules

 
  , bundles = require('./bundles')
  , engine = require('./lib/engine')
  , oauth2 = require('./lib/oauth2')

Other Dependencies

 
  , nconf = require('nconf')
  , director = require('director')
  , _ = require('underscore')._
  , cronJob = require("cron").CronJob
;

Use nconf to grab commandline params and read config.json

 
nconf.argv().file({ file: 'config.json' });

If --dev is passed use the development config section

 
var config = nconf.get('dev') ? nconf.get('development') : nconf.get('live');

Run little-spas as a service

 
if (nconf.get('service')) {

Specify output and error log files

 
	var	out = fs.openSync('./logs/spasout.log', 'a'),
		err = fs.openSync('./logs/spaserr.log', 'a');

Spawn the process

 
	var spasService = spawn('node', ['little-spas', nconf.get('dev') ? '--dev' : ''], {
		detached: true,
		stdio: [ 'ignore', out, err ]
	});
	
	spasService.unref();
	
	console.log("little-spas is listening on port " + config.port);
	
	process.exit();
	
} else {

Our Routes

 
	var router = new director.http.Router({

This is the return route for authentication services

 
		'/auth': {
			get: function() {
				if (_.has(querystring.parse((url.parse(this.req.url).query)), 'code')) {
					oauth2.saveCode ( this.res, querystring.parse((url.parse(this.req.url).query)).state.split(','), querystring.parse((url.parse(this.req.url).query)).code);
				}
			}
		},

This route needs to be removed and changed to a command line call. Anybody could revoke creds right now

 
		'/revoke/:cred': {
			get: function(cred) {
				oauth2.revoke ( this.res, cred );
			}
		},

A bundle is being requested

 
		'/bundle/:bid': {
	    	get: function(bid) { 
	    		engine.fulfill ( this.res, bid, bundles[bid], querystring.parse((url.parse(this.req.url).query)).callback );
	    	}
		}
	});

Schedule jobs defined in bundles

 
	_.each(bundles, function (bundle, bid) {
		_.each(bundle, function (api, key) {
			if (api.schedule) {
				new cronJob(api.schedule, function(){
		    		engine.refresh(api, key, bid, bundle);  
		    	}, null, true);
		    }
		});
	});

Create our server

 
	var server = http.createServer(function (req, res) {
		router.dispatch(req, res, function (err) {
			if (err) {
				res.writeHead(404);
				res.end();
			}
		});
	});
	
	server.listen(config.port);
