1. Develop and publish node.js apps to the cloud2. Simple CLI interface and built-in webserver3. Built-in ACS support4. Integrated with Titanium Studio5. It's Javascript but for the server!
Install Node.ACS
Node.ACS runs on top of node.jsStudio installs Node and NPM by defaultIf you don't, install it from http://nodejs.org/Run node -v to make sure you have it and then install ACS
node -v
sudo npm install -g acs
Login to Node.ACS
acs login
Create a new Node.ACS
acs new -my_app_name-
Starting your first Node.ACS
acs run
Viewing on the browser
Publishing first app
acs publish
acs publish --force
First app published
MVC Framework
Config.json{ "routes": [ { "path": "/", "callback": "application#index" } ], "filters": [ { "path": "/", "callback": "" } ], "websockets": [ { "event": "", "callback": ""} ]}
Callbacks are in filename#functionname formatDefault HTTP Method is GET. For post we need to add"method":"post"Web Sockets are a whole different talk. More info athttp://socket.io/
A simple Web Site
A simple Web Site(config.json)
{ "routes": [ { "path": "/", "callback": "application#index" }, { "path": "/home", "callback": "application#home" }, { "path": "/login", "method":"post", "callback": "application#login" }, { "path": "/logoff", "callback": "application#logoff" } ], "filters": [ { "path": "/home", "callback": "session_filter#validateSession" } ], "websockets": [ { "event": "", "callback": ""} ]}
Configure your app to tracksessions(app.js)
// initialize appfunction start(app, express) { //set favicon app.use(express.favicon(__dirname + '/public/images/favicon.ico')); //instantiate session management app.use(express.session({secret: '1234567890QWERTY'}));}
// release resourcesfunction stop() { }
There's more to sessions. See http://expressjs.com
A simple Web Site(application.js)
function index(req, res) { res.render('index', { title: 'Welcome to Node.ACS!' });}
function login(req, res) { var uid=req.body.uid; var pwd=req.body.pwd; var name=req.body.name;
if (uid==='appc' && pwd=='nodeacs'){ req.session.uid=uid; req.session.pwd=pwd; req.session.name=name; res.redirect('/home'); }else{ res.send(500, { error: 'something blew up' }); }}
function logoff(req, res) { req.session.uid=null; req.session.pwd=null; req.session.name=null; res.redirect('/'); }
function home(req, res) { res.render('home', { title: req.session.name });}
The Index View(index.ejs)
<!DOCTYPE html><html> <head> <title>Index</title> <link rel='stylesheet' href='/css/style.css' /> </head> <body> <h2>Node.ACS</h2> <form action="/login" method="post"> <div>Name<input type="text" name="name"/></div> <div>UID<input type="text" name="uid"/></div> <div>PWD<input type="password" name="pwd"/></div> <div><input type="submit" value="Go"></div> </form> </body></html>
The Home View(home.ejs)
<!DOCTYPE html><html> <head> <title><%= title %></title> <link rel='stylesheet' href='/css/style.css' /> </head> <body> <h2>Node.ACS</h2> <p>Welcome Home, <%= title %>!</p> <div><a href="/logoff">Log off</a></div> </body></html>
Validating sessions(session_filter.js)
function validateSession(req, res, next) { if(req.session.uid === null) { res.redirect('/'); } else { next(); }}

Creating a "catch-all" routeapp.get('/get/*',function(req,res){ urlParam=req.path.replace(/\/$/, "").split('/').pop(); // do what you want with your url parameter});
