The document discusses Ionic 2, an SDK for developing hybrid mobile apps using web technologies. Ionic 2 aims to simplify app development and improve navigation capabilities. It leverages new web standards like ES6 and TypeScript to provide robust tooling and an easy setup process so developers can focus on building their apps. Ionic 2 pushes the limits of what's possible with the web and ensures the future remains bright for web technologies.

1. MOBILE APPS WITH THE WEB
Mike Hartington | @mhartington

2. BEFORE WE JUMP
INTO THINGS...

3. IONIC V1!
SDK for Developing Hybrid Apps
Focused on mobile apps first
Sass for easy customization
Angular for code structure

4. EMPOWERED DEVELOPERS
EVERYWHERE
Web Developers could now
participate in making apps!

5. THE STATS
34th most popular OSS project
(24,000+ stars on GitHub)
Meetup Groups around the world
Ionic apps top app store charts
Used everywhere from Fortune 50 co’s to
YC/TechStars companies

6. WAIT, THIS WHOLE
"WEB THING" AGAIN?

7. WE TRIED THIS
BEFORE AND WERE
NOT IMPRESSED

8. JS => NATIVE
FALL BACK TO
NATIVE

9. BUT THE WEB HAS GOTTEN
A LOT BETTER

10. IONIC 2
Pushing whats possible with the web

11. V2 GOALS
Simplicity
Navigation
Tooling
Make NG2 Easy

12. SIMPLICITY
Make it easy to understand HTML

13. CLASSES
<a class="button button-positive"></a>
<button type="button" class="btn btn-default"></button>
<a class="small expanded button" href="#"></a>

14. <div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">1</button>
<button type="button" class="btn btn-default">2</button>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown"
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Dropdown link</a></li>
<li><a href="#">Dropdown link</a></li>
</ul>
</div>
</div>

15. CSS CLASSES CAN GET
COMPLEX AND CLUTTERED

16. JUST USE RAW ELEMENTS
Easier to understand and less clutter

17. THE STYLES DON'T CHANGE
<ion-list>
<ion-list-header>
Action
</ion-list-header>
<ion-item>Terminator II</ion-item>
<ion-item>The Empire Strikes Back</ion-item>
<ion-item>Blade Runner</ion-item>
</ion-list>
but the markup becomes much clearer

18. EQUALLY EASY TO STYLE
AND EXTEND
ion-avatar{
border-radius: 30px;
}
ion-card{
width: 80%;
}

19. NAVIGATION
More robust and powerful

20. I NEED TO OPEN A
MODAL, THEN
NAVIGATE TO A
SUBVIEW
I WANT TO CREATE
A SUBVIEW IN A
SIDEMENU

21. V1'S ROUTING
.config(function($stateProvider){
$stateProvider
.state('firstpage', {
url:'/firstpage',
templateUrl: 'firstpage.html'
})
.state('secondpage', {
url:'/secondpage',
templateUrl: 'secondpage.html'
})
.state('thirdpage', {
url:'/thirdpage/:id',
templateUrl: 'thirdpage.html'
});
});
UI-Router

22. DOESN'T GIVE THE
FLEXIBILITY YOU WANT
Navigation: user experience
URLs don't offer that
Developers NEED to be in control

23. PUSH/POP/PARAMS
import SecondPage from '../secondpage';
export class FirstPage {
constructor(
public nav: NavController) {};
pushState() {
this.nav.push(SecondPage)
};
};

24. FULL CONTROL
Push pages on to the nav stack
Pop pages off the nav stack
Insert/Remove/Update
Create app history from nothing
Update the URL as an option

25. TOOLING FOR
EVERYONE
Building apps with new standards

26. JAVASCRIPT HAS CHANGED
ES6 brings many new features
Typescript builds on top of that
Tooling that IDEs can hook into
All of this, helping you to developer faster

27. ES6
Modular: Import what you need & and
gets rid of globals
Scoping: let defines a block-scoped
variable
Promises: Built into the language natively
Classes: Simpler syntax for building
objects

28. TYPESCRIPT
ES6 + Decorators + Types
Ionic 2 and NG2 built using TS
Optional Types for stricter coding
Code completion in your editor

29. ALL THESE NEW
FEATURES....
BUT HOW DO I START?

30. DON'T WORRY, IONIC'S
GOT YOUR BACK!

31. Ionic provides a TypeScript setup
You can just focus on writing your app
A build system handles everything else!
It "just works"™

32. SETUP
$ NPM INSTALL -G IONIC@BETA
$ IONIC START MYAPP --V2
$ CD MYAPP
$ IONIC SERVE

33. FINAL MESSAGE
Ionic 2 is really pushing what
we can do with the web
The future is looking great for web and
web technologies
Always bet on the web

34. THANK YOU!
