Ember-Data-Echonest

This addon provides an abstraction layer for accessing the Echo Nest V4 APIs via Ember-Data.

Requirements

This project is intended to work with Ember-Data 2.x, so if you wish to use it with a previous version, please file an issue. If there is enough interest, we can work on handling older versions as well. Better yet, we'd love you to submit a PR adding this functionality!

EDEN uses the BabelJS polyfill for additional ES6 features (such as includes), so please make sure you have enabled it in your app!

Obtaining an Echo Nest API Key

In order to use this addon, you must register for an Echo Nest API Key. If you see three keys on your profile (API/Consumer/Shared Secret), you can ignore the other two (deprecated) and use the API Key.

Note: API Keys are intended for non-commercial use. If you intend to make more money than simply covering your hosting costs, please contact Echo Nest for licensing. I also highly recommend reviewing their API Ground Rules.

Installation

ember install ember-data-echonest

Once you have installed the addon, you need to add your API Key to the ENV config. We highly recommend using ember-cli-dotenv to save your key to a .env file so that you don't have to upload it to your project repo. I've called mine ECHONEST_KEY, and you can view the demo app's config to see how I've injected the key.

Usage

The addon exposes a number of models, adapters, and serializers you can use to access data from the Echo Nest API. If a particular API is not supported, please review our issue list and create a new one if it has not yet been requested. Contributions especially welcome!

If you have not already, update your application to include the BabelJS Polyfill for new ES6 features such as includes:

//ember-cli-build.js
new EmberApp(defaults, {
    babel: {
      includePolyfill: true
    }
});

Methods

Each section below details the usage of a particular type of data provided by Echo Nest. Within these sections are specific methods used for retrieving that model type. In order to utilize these APIs, you must pass the name of the method you wish to use for your request:

this.store.query('echonest-genre', {
  method: 'list'
});

This parameter must be passed in order for Ember-Data-Echonest to know how to construct the proper request url.

Buckets

Many of the APIs have additional query params called buckets that allow you to specify additional information to be returned in the response. In order to use these buckets, you would pass a query param bucket to Ember-Data with an array of strings containing the names of each bucket to be included. Every model type has the same buckets available, unless otherwise noted.
