This document discusses building websites using Node.ACS, which allows developing and publishing Node.js apps to the cloud. It provides an overview of Node.ACS and steps for installing, creating, and publishing a simple website using Node.ACS, including using an MVC framework and sessions. Examples of configuration files, controllers, and views are also included.

{
"routes":
[
{ "path": "/", "callback": "application#index" }
],
"filters":
[
{ "path": "/", "callback": "" }
],
"websockets":
[
{ "event": "", "callback": ""}
]
}
Callbacks are in filename#functionname format
Default HTTP Method is GET. For post we need to add
"method":"post"
Web Sockets are a whole different talk. More info at

Building websites with Node.ACS
- 2. About me 1. Have been using Titanium since late 2009 2. Former Titanium trainer in the Caribbean and Latin America 3. Currently work as Lead Developer Evangelist 4. Obsessed with cross-platform mobile develoment 5. Love Javascript hacking and technology startups 6. I'm a hacker in constant training
- 3. What is Node.ACS 1. Develop and publish node.js apps to the cloud 2. Simple CLI interface and built-in webserver 3. Built-in ACS support 4. Integrated with Titanium Studio 5. It's Javascript but for the server!
- 4. Install Node.ACS Node.ACS runs on top of node.js Studio installs Node and NPM by default If 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
- 9. Publishing first app acs publish acs publish --force
- 11. MVC Framework
- 12. Config.json { "routes": [ { "path": "/", "callback": "application#index" } ], "filters": [ { "path": "/", "callback": "" } ], "websockets": [ { "event": "", "callback": ""} ] } Callbacks are in filename#functionname format Default HTTP Method is GET. For post we need to add "method":"post" Web Sockets are a whole different talk. More info at http://socket.io/
- 14. 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": ""} ] }
- 15. Configure your app to track sessions (app.js) // initialize app function start(app, express) { //set favicon app.use(express.favicon(__dirname + '/public/images/favicon.ico')); //instantiate session management app.use(express.session({secret: '1234567890QWERTY'})); } // release resources function stop() { } There's more to sessions. See http://expressjs.com
- 16. 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 }); }
- 17. 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>
- 18. 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>
- 19. Validating sessions (session_filter.js) function validateSession(req, res, next) { if(req.session.uid === null) { res.redirect('/'); } else { next(); } }
- 22. Creating a "catch-all" route app.get('/get/*',function(req,res){ urlParam=req.path.replace(//$/, "").split('/').pop(); // do what you want with your url parameter });
