Introduction to Polymer

The web components library

By Alberto Fernandez / @AlbertoFdzM

Polywhat?

According to Wikipedia, Polymer is:

(Greek: poly-, "many" + -mer, "parts") a large molecule, or macromolecule, composed of many repeated subunits.

Polymer is a library that allows to develop under web components standars taking to the present one of the many futures of the web development. Also it provides tools and simple forms to develop web components.

Advantages of Polymer against other Libraries / Frameworks

{{Fight GIF}}

One of the pros of Polymer over the other frameworks is that this one is based on Standars and tends to be simple, it is not a overcharged framework as Angular or Backbone providing a bunch of methods or modules, it is more like a library that tries to helps you with the develop of web components adding some extras.

A Simple Polymer Component

The simplest Polymer component is here to helps you understand how to start to develop Polymer Web Components.

Hello Polymer Example

hello-digitas.html 
<link rel="import" href="/lib/polymer/polymer.html">

<dom-module id="hello-digitas">
  <template>
    Hello Digitas!
  </template>

  <script>
    Polymer({
      is: 'hello-digitas'
    });
  </script>
</dom-module>

The easiest way to create a Polymer element is to create an html file with the same name that the element will have, in this case hello-digitas.html

Time to use it!

<!DOCTYPE html>
<html lang="en">
<head>


  <script src="/lib/polymer/webcomponents-lite.min.js"></script>

  <link rel="import" href="hello-digitas.html">
</head>
<body>


  <hello-digitas>
</body>
</html>

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';
      }
    }
  }
}

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.
