Collage is a Framework for Live Collages

Collage brings together many public APIs, along with a method of presenting media within a limitless two-dimesional space to create memorable and meaningful experiences. It's a mixture between Big Surface, Giant Quadtree, and a public API library.

Use

For plain JavaScript applications, use the dist/collage.js, which will inject the Collage module object to the global scope (i.e. it creates window.collage). You can also use this file as an AMD or CommonJS module. If you use bower, you can install collage with bower install collage.

Depending on which loaders you use, you will need to include these in your HTML doc, before starting the collage:

<!-- Youtube Iframe API -->
<script src="//www.youtube.com/iframe_api"></script>

<!-- Twitter API -->
<script src="//platform.twitter.com/widgets.js"></script>

<!-- Facebook API -->
<div id="fb-root"></div>
<script>
	(function(d, s, id) {
	  var js, fjs = d.getElementsByTagName(s)[0];
	  if (d.getElementById(id)) return;
	  js = d.createElement(s); js.id = id;
	  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
	  fjs.parentNode.insertBefore(js, fjs);
	}(document, 'script', 'facebook-jssdk'));
</script>

Content Sources

These are referred to as loaders in the codebase.

• Facebook (like boxes)
• Reddit (images and embeds)
• Youtube
• Flickr
• Google News
• Google Plus
• Twitter (currently broken due to auth changes)
• NY Times (requires a reverse-proxy due to lack of CORS headers)

Check the loader configurations for how to query them for content.

API

Collage extends Big Surface, all API methods that are available for Big Surface is also available for Collage. In the API collage refers to the module object and collageInstance refers to a Collage instance which is created via collage.create.

collage.create(container)

Constructor function which returns a new Collage instance. The container is the element which will contain the collage.

collageInstance.load(tagName, loaderName, loaderConfig)

Loads the media from the given loaderName according to the loaderConfig and assigns the loaded media to the tagName.

var collageInstance = collage.create(document.body);
collageInstance.load('some fb content', 'facebook', {
    minLikes: 200,
    query: 'popcorn'
}).then(function(){
	// Wait for the loading to be finished, then
	// start the collage (filling the center) and set the active tags
	collageInstance.start('some fb content');
	collageInstance.speed(8);
});

collageInstance.load(tagName, loaderMap)

Loads the media from the given loaderName : loaderConfig mapping and assigns the loaded media to the tagName.

var collageInstance = collage.create(document.body);

collageInstance.load('my content', {
  facebook: [
    {    
      minLikes: 200,
      query: 'popcorn'
    },
    {
      ids: ["110452248983275"]
    }
  ],
  twitter: [
    { query: 'popcorn' },
    { query: 'caramel' }
  ]
}).then(function(){
	// Wait for the loading to be finished, then
	// start the collage (filling the center) and set the active tags
	collageInstance.start('my content');
	collageInstance.speed(8);
});

collageInstance.start(opt_var_args)

Starts the transform loop of the collage (allows for movement) and optionally sets the active tags to the given arguments.

collageInstance.pause(opt_duration)

Brings the collage movement to a halt within the given time duration (or immediately if none provided).

collageInstance.resume(opt_duration)

Resumes collage movement to the state it was in previous to a pause call. If a duration is provided, the speed will tween to the limit within the given time period.

collageInstance.setActiveTags(var_args)

Sets the given tags as the 'active' tags which media for the collage will be pulled from.

collageInstance.add(tagNames, elements)

Adds the given element(s) to the given tag(s).

collageInstance.remove(tagNames, elements)

Removes the given element(s) from the given tag(s).

collageInstance.get(var_args)

Gets the elements for the given tag names.

collageInstance.showElement(element, left, top, show)

Inserts an element directly in the collage surface at left, top (in pixels). If show is set to true, the element is placed visibly, otherwise hidden.

collageInstance.loader

A map of available loaders which you can extend during run-time.

collageInstance.fill()

Fills the visible center of the screen with elements.

Loader Configuration Options

Loaders are where you get the content for the collage from. The content from the loaders are associated with one or more tags, which the collage will use to populate itself with.

Developing

This project uses boilerplate-gulp. Run 'gulp dev' to develop and have incremental builds, continuous testing, etc. Run 'gulp' to run regenerate the dist files.
