How can I go mobile?

Native aproach

iOS

Objective-C or Swift

Android

Java

Windows

C#

et cetera...

  • Cordova
  • PhoneGap

  • Onsen.io

Hybrid approach

  • Framework 7
  • Mobile Angular UI
  • Intel XDK
  • Sencha Touch
  • Kendo UI
  • Appium.io
  • Trigger.io

Hybrid handicaps

Slow

 

Feels like a webview

 

Complicated development

 

Problematic native functionalities

What is this

Ionic

thing?

Ionic is an open source

front-end SDK for developing

hybrid mobile apps with HTML5."

Performant!

Angular friendly!

Native focused!

Awesome CLI!

FUN! » play.ionic.io

Emerging Tech

Getting started

// Install the generator
$ npm install -g cordova ionic

// Start an app
$ ionic start myApp tabs

// Let's run it
$ cd myApp
$ ionic platform add ios
$ ionic build ios
$ ionic emulate ios

*Don't forget to install the android SDK

The project folder

Easy to be native

CSS:

headers, tabs, lists, inputs, buttons, icons, etc. 

JS:

gestures, events, popups, sliding menus, etc. 

And all this with ion- tags, attributes and AngularJS modules. The docs is great.

CLI is awesome!

$ ionic start myapp [template]

Named templates, local directories, github-codepen-plunker urls

Livereload works like a charm... Config it via the ionic.project file

$ ionic serve
$ ionic serve --lab
$ ionic platform ios android
$ ionic build android
$ ionic emulate/run [platform] --livereload --consolelogs

Try it on mobile

$ ionic resources --icon --splash
$ ionic package debug android
$ ionic upload
$ ionic share <EMAIL>

There is a great app called Ionic View:

There is much-much more:

$ ionic help

And the native stuff!

Cordova + Angular = ngCordova

$ bower install ngCordova

... angular.module('myApp', ['ngCordova']) ...


$ ionic plugin add cordova-plugin-camera

... module.controller('PictureCtrl', function($scope, $cordovaCamera) {
    ... $cordovaCamera.getPicture( ...

There is a big list of plugins and it's also easy to write one!

Let's

create

something!

Something simple

Let's create an app, where

we can vote for the meetup topics!

.. but useful .. 

.controller("SampleCtrl", function($scope, $firebaseObject, $firebaseArray) {
  
  var ref = new Firebase("https://scorching-torch-4715.firebaseio.com/sampleEntity");

  // download the data into a local object
  $scope.sampleData = $firebaseArray(ref);

Real time database in the cloud

Developed by Google

Works well with Angular

Dependencies, first of all

    // Ionic CSS
    link(href='//code.ionicframework.com/nightly/css/ionic.css', rel='stylesheet')  
    
    // Ionic bundle
    script(src='//code.ionicframework.com/nightly/js/ionic.bundle.js')
    
    // Angular
    script(src='https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js')
    
    // Firebase
    script(src='https://cdn.firebase.com/js/client/2.2.4/firebase.js')
    
    // Angular-fire
    script(src='https://cdn.firebase.com/libs/angularfire/1.1.1/angularfire.min.js')

We need:

Templates

 

Routing

 

and some logic

Check it on codepen.io

Go and publish

Can be useful: docs

$ cordova build --release android

$ keytool -genkey -v -keystore my-release-key.keystore -alias alias_name 
-keyalg RSA -keysize 2048 -validity 10000

$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore 
my-release-key.keystore HelloWorld-release-unsigned.apk alias_name

$ zipalign -v 4 HelloWorld-release-unsigned.apk HelloWorld.apk

Publish and enjoy!
