Wozu hilft es mir?

  • DOM Manipulations (jqLite)
  • History
  • Routing
  • Caching
  • Ajax/Promises

Modules

AngularJS basiert auf der Verwendung von Modulen

  • Macht den Code besser wart- und lesbar
  • Erleichtert die Wiederverwendung von Funktionalitäten
  • Definition von Abhängigkeiten anderer Module
  • Die Hauptanwendung ist ein Modul
            var app = angular.module('demo',[]);

Directives

  • Erweitern die Funktionalität von HTML Tags
  • Hilfe bei Interaktionen mit DOM Elementen
  • Markierung mittels Attribut, Element oder CSS Klasse
            
              <!Doctype html> <html ng-app="demo" > <head> <meta charset="UTF-8"> <title>Angular Demo</title> </head> <body> Name:
              <input type="text" ng-model="name">
              <div ng-repeat="dev in devs"></div>
              </body> </html>

Dependency Injections

  • Macht den Code besser wart- und lesbar
  • Erleichtert die Wiederverwendung von Funktionalitäten
  • Definition von Abhängigkeiten anderer Module
  • Die Hauptanwendung ist ein Modul
            var app = angular.module('demo',['ngRoute', 'ngAnimate']);

Expression

Einbindung von Werten in die Ansicht

  • Macht den Code besser wart- und lesbar
  • Erleichtert die Wiederverwendung von Funktionalitäten
  • Definition von Abhängigkeiten anderer Module
  • Die Hauptanwendung ist ein Modul
            
              <!Doctype html> <html ng-app="demo" > <head> <meta charset="UTF-8"> <title>Angular Demo</title> </head> <body> Name:
              <input type="text" ng-model="name">
              <ul ng-repeat="dev in devs">
                <li>{{dev.name}}</li>
              </ul>
              </body> </html>

Fragments

Hit the next arrow...

... to step through ...

... a fragmented slide.

This slide has fragments which are also stepped through in the notes window.

Fragment Styles

There's different types of fragments, like:

grow

shrink

fade-out

current-visible

highlight-red

highlight-blue

Transition Styles

You can select from different transitions, like: None - Fade - Slide - Convex - Concave - Zoom

Themes

reveal.js comes with a few themes built in: Black (default) - White - League - Sky - Beige - Simple Serif - Blood - Night - Moon - Solarized

Slide Backgrounds

Set data-background="#dddddd" on a slide to change the background color. All CSS color formats are supported.

Image Backgrounds

            <section data-background="image.png">

Tiled Backgrounds

            <section data-background="image.png" data-background-repeat="repeat" data-background-size="100px">

Video Backgrounds

              <section data-background-video="video.mp4,video.webm">

... and GIFs!

Background Transitions

Different background transitions are available via the backgroundTransition option. This one's called "zoom". 

          Reveal.configure({ backgroundTransition: 'zoom' })

Background Transitions

You can override background transitions per-slide. 

          <section data-background-transition="zoom">

Pretty Code

          function linkify( selector ) { if( supports3DTransforms ) { var nodes = document.querySelectorAll( selector ); for( var i = 0, len = nodes.length; i < len; i++ ) { var node = nodes[i]; if( !node.className ) { node.className += ' roll'; } } } }

Code syntax highlighting courtesy of highlight.js.

Marvelous List

Fantastic Ordered List

Clever Quotes

These guys come in two forms, inline: “The nice thing about standards is that there are so many to choose from” and block:

“For years there has been a theory that millions of monkeys typing at random on millions of typewriters would reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.”

Intergalactic Interconnections

You can link between slides internally, like this.

Speaker View

There's a speaker view. It includes a timer, preview of the upcoming slide as well as your speaker notes.

Press the S key to try it out.

Oh hey, these are some notes. They'll be hidden in your presentation, but you can see them if you open the speaker notes window (hit 's' on your keyboard).

Export to PDF

Presentations can be exported to PDF, here's an example:

Global State

Set data-state="something" on a slide and "something" will be added as a class to the document element when the slide is open. This lets you apply broader style changes, like switching the page background.

State Events

Additionally custom events can be triggered on a per slide basis by binding to the data-state name. 

          Reveal.addEventListener( 'customevent', function() { console.log( '"customevent" has fired' ); } );

Take a Moment

Press B or . on your keyboard to pause the presentation. This is helpful when you're on stage and want to take distracting slides off the screen.
