Appcelerator Cloud Services (ACS) as Instant Mobile Backend

• Easy to use

• Cross Platform (REST Api based)

• Predefined object models

• Custom Objects and Fields

• No Server Code Needed

The Good

• Custom Code

• Web Hosting

• Support of Custom URLs

• Can have extra overhead with the network and battery consumption

What’s Missing

Introducing Custom Cloud Services (Node.ACS)

• Complete Solution to your Mobile Backend

• JavaScript for both Client and Server

• Fully Integrated with ACS

Node.js + ACS

JS

• Use JavaScript to write Web Servers

• Based on Google’s V8 Engine

• Event-driven/None-blocking IO

• Lightweight and efficient

Node.js in a Nutshell

• Performance and Scalability

• Easy to Integrate Network Components

• JavaScript

Demo and Sample Code

Web Server

Sample web server to display your

app data stored in ACS

var user = { session:"",};api.login = function(req, res) {

if(user.session === ""){ ACS.Users.login({login: req.body.un,password: req.body.pw}, function(e) { if(e.success && e.success === true){

user.session = e.meta.session_id;}else{

res.redirect(version+'/index?msg='+e.message); } }, req, res); }else{ res.redirect(version+'/show'); }}

What’s wrong?

Websocket

A group chat app

based on websocket

websocket.message = function(data, socket) {socket.broadcast.emit('message', data);

};

Group Chat

// Received a message iosocket.on('message', function(message) {

// Display the message});

// User types a message$('#outgoingChatMessage').keypress(function(event) {

iosocket.emit('message', $('#outgoingChatMessage').val());}
