jQuery Based EchoNest API Plugin

Access the wonderful http://www.echonest.com/ API directly from Javascript through a simple yet expressive interface. Requires jQuery. jQuery/Underscore templates optional but you're going to be creating yourself a lot of work if you don't use it...

Introduction

You want artist images?

var echonest = new EchoNest("YOUR_API_KEY");
echonest.artist("Radiohead").images( function(imageCollection) {
	$('body').prepend( imageCollection.to_html('<img src="${url}">') );
});

Most collections received back from the plugin can either be access directly, converted to an array of strings or if you have jQuery templates installed, converted directly to a string of HTML (as in the above example). Accessing collections through jQuery templates can yield surprisingly concise and expressive code.

When converting collections to html you may pass in additional options to control the range of items converted. This is useful if you only want to return a small number of results:

var echonest = new EchoNest("YOUR_API_KEY");
echonest.artist("Radiohead").images( function(imageCollection) {
	$('body').prepend( imageCollection.to_html('<img src="${url}">', {start: 0, end: 5}) );
});

This will return only the first five results in the collection.

Audio too!

var echonest = new EchoNest("YOUR_API_KEY");
echonest.artist("Hybrid").audio( function(audioCollection) {
	$("body").append( audioCollection.to_html('<p>${artist} - ${length} long<br /><audio src="${url}" controls preload="none"></audio></p>') );
});

We can output audio directly into the browser using the HTML5 audio tag! Sexy!

Collections

Most queries to the EchoNest API result in collections. Collections can either be natively iterated using the jQuery templates, or particular records can be extracted using the .at(x) function. For example, lets get the second Radiohead biography (by their EchoNest ID). Templates conversion is normalised over all the different engines.

var echonest = new EchoNest("YOUR_API_KEY");
echonest.artist("ARH6W4X1187B99274F").biographies( function(biographyCollection) {
	$("#artistBiography").append( biographyCollection.at(1).to_html('<p>${text} <br/>by: <strong>${site} - <span class="license">${license_type}</span></strong></p>') );
});

By setting the .at(x) on a collection, any further calls to that collection will keep working with that record. To work with all records again, call .at(null)

Collections can be manually iterated over by calling .getData(). E.g.

$.each(biographyCollection.getData(), function(count, item) {
	// your code here
});

Ongoing Development

Development is ongoing, however the interface to the API is not expected to change. Tests and documentation coming soon.
