Why ?

Topics we will cover• Architecture

• Build the Backend

• Build the iOS app

• Summary

MongoDB• Open source

• High performance, high availability, automatic scaling

• Document database

DEMO MongoDB

Node.JS• A platform built on Google’s Open Source V8 engine

• event-driven, non-blocking I/O model

• JavaScript based

var http = require(‘http');http.createServer(function (req, res) {

res.writeHead(200, {'Content-Type': ‘text/plain'}); res.end('Hello World\n');

}).listen(1337, '127.0.0.1');

console.log('Server running at http://127.0.0.1:1337/');

Express• Express: Node.JS Web Application Framework

• npm install express

Routing

// respond with "Hello World!" on the homepage app.get('/', function (req, res) { res.send('Hello World!'); })

// accept POST request on the homepage app.post('/', function (req, res) { res.send('Got a POST request');})

// accept PUT request at /userapp.put('/user', function (req, res) { res.send('Got a PUT request at /user'); })

// accept DELETE request at /userapp.delete('/user', function (req, res) { res.send('Got a DELETE request at /user'); })

Mongoose• MongoDB object modeling framework

• npm install mongoose

DEMO Basic Car repository

EPAM ROAD

Rapid Objective-C Applications Development• Features

• Support for attributes (annotations), reflection

• Services (service locator pattern)

• Serialization (JSON, XML)

• Web Service client w/ zero-coding using attributes

• CocoaPods integration

Attributes

RF_ATTRIBUTE(RFSerializable)@interface RDCar : NSObject { … }

RF_ATTRIBUTE(RFWebServiceCall, method = @"GET", relativePath = @"/cars", prototypeClass=[RDCar class])- (id)carListWithSuccess:failure:;
