Um pouco de história antes...

Javascript

1995

Brendan Eich

XMLHttpRequest

1999

Internet Explorer 5

Utilizado para trazer informação do servidor para o cliente durante a execução do JavaScript.

JSON (Javascript Object Notation)

2001

Douglas Crockford

Padrão utilizado para guardar informações utilizando a sintaxe do Javascript. Pode ser colocado em um JSON: Objetos, Strings, Numbers e Booleanos.

AJAX

2005

Google Maps

Conjunto de tecnologias utilizadas para atualizar somente uma parte da página de acordo com as informações buscadas pelo XMLHttpRequest. Com o Ajax, outras características foram trocadas, como por exemplo a utilização de JSON ao invés de XML, WebSockets ao invés de HTTP.

jQuery

2006

John Resig

jQuery é uma biblioteca que foi e é bastante utilizada para a manipulação do HTML, pos abstrai e muito o tanto de código necessário.

NodeJS (v8)

2009

Ryan Dahl

  • Usa uma API não-bloqueante em uma thread.
  • Developers Web já utilizam Javascript
  • Baseado em Eventos(callbacks) pois já era utilizado com a DOM.

Arquitetura Cliente/Servidor

Arquitetura mais utilizada hoje em dia.

Além da Cliente/Servidor, qual outra arquitetura é utilizada hoje em dia?

Peer-to-Peer ( Torrent )

E porquê estamos falando de arquitetura Cliente/Servidor?

AngularJS

O que é AngularJS?

Framework open-source criado em 2010 por Miško Hevery e mantido atualmente pela Google. Com o AngularJS, o programador tem o poder de criar uma Arquitetura MVW* e seus próprios elementos HTML.

MVW* = Model-View-Whatever

Características Principais

  • Single Page Application
  • Modularização da Aplicação
  • Suporte a testes Unitários
  • Two Way Data-Binding
  • Directives

Vertical Slides

Slides can be nested inside of each other.

Use the Space key to navigate through all slides.

Basement Level 1

Nested slides are useful for adding additional detail underneath a high level horizontal slide.

Basement Level 2

That's it, time to go back up.

Slides

Not a coder? Not a problem. There's a fully-featured visual editor for authoring these, try it out at http://slides.com.

Point of View

Press ESC to enter the slide overview.

Hold down alt and click on any element to zoom in on it using zoom.js. Alt + click anywhere to zoom back out.

Touch Optimized

Presentations look great on touch devices, like mobile phones and tablets. Simply swipe through your slides.

Markdown support

Write content using inline or external Markdown. Instructions and more info available in the readme.

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';
      }
    }
  }
}

Marvelous List

  • No order here
  • Or here
  • Or here
  • Or here

Fantastic Ordered List

One is smaller than... Two is smaller than... Three!

Tabular Tables

Item Value Quantity Apples $1 7 Lemonade $2 18 Bread $3 2

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.
