=============================================================================== Jah'Spotify Project

Introduction

Jah'Spotify is a Java wrapper built on top of the Spotify native APIs (libspotify) exposed both as an HTML5 UI and a JSON REST based API

Currently supports:

• retrieving library (all user playlists/folders)
• retrieve a playlist
• retrieve a folder (including/excluding sub-folders and playlists)
• retrieve an album
• retrieve a track
• retrieve an image
• add tracks to a queue (single queue currently supported)
• play tracks
• pause/skip functions
• dynamic playlist using echonest apis
• basic historical track list view
• very basic android app for remote control
• JSON reset based API
• web-ui based on JQuery Mobile

In addition, all the above functions are accessible over a JSON based RESTful API (provided by the services and web modules).

Note: Currently, JahSpotify relies on existing playlists created from Spotify - there is currently no option to add playlists/folders using the API or UI - it is being worked on ;)

To build

Jah'Spotify supports the Linux and Windows versions of libspotify (see below for more details on building on Windows).

Prerequisites

The following prerequisites are required in order to build Jah'Spotify

• libspotify
• Spotify API key
• OpenAL

Checking out the sources

To build the sources first check them out from git

git clone git://github.com/johanlindquist/jahspotify.git
cd jahspotify

Preparing Spotify API key and libraries

Next, you need to download and install libspotify & request an API key from Spotify. This can be done on the libspotify website or via your OS package provider (Homebrew for OS X for example)

Generate the key and download the C code version of it. Place this in a file called AppKey.h in the

native/src/main/native/inc

directory. You may want to place some #ifndef APPKEY statements in this to prevent linking problems.

Performing the build

Ensure that your JAVA_HOME environment variable points to the JDK (v1.6.x) you want to use.

export JAVA_HOME=<path/to/your/jdk>

Finally, execute the Maven build

mvn clean install

Building on Windows

Before compiling

1. Download MinGW and put the bin folder in your PATH.
2. Download the OpenAL SDK from and copy the include folder to the MinGW include folder and rename it to AL
3. The native pom.xml has a reference to a local LibSpotify folder. Change this to your own Spotify folder. You'll get an error that the api.h file can't be found if you don't.
4. Add a reference to your OpenAL installation folder

You can find the OpenAL SDK at:

http://connect.creativelabs.com/developer/Wiki/OpenAL%20SDK%20for%20Windows.aspx

Next, define the following environment properties:

JAHSPOTIFY_SPOTIFY_DIR=c:\path\to\spotify\installation\LibSpotify\
JAHSPOTIFY_OPENAL_DIR=c:\path\to\openal\installation\OpenAL 1.1 SDK\

Performing the build

To build, simply execute maven build

mvn clean install

Building on OX X

Depending on your

Running

Jah'Spotity will run both from within Maven (using Jetty) and in a web container such as Tomcat.

Prerequisites

Jah'Spotify uses MongoDB for storing the historical statistics and tracks played. This can be downloaded from MongoDB. As long as MongoDB is running when Jah'Spotify is started (and the connection does not require credentials), it should work.

Configuration

TDB

Running on Windows

For windows, you will need to download a few more dependencies:

• pthreads (http://sources.redhat.com/pthreads-win32/). pthreadGC2.dll needs to be in your path.
• Install the OpenAL SDK for Windows

Using Maven/Jetty

To run up the Jah'Spotify with Maven/Jetty

mvn jetty:run -Djahspotify.spotify.username=<your username> -Djahspotify.spotify.password=<your password>

NOTE: The username and password can also be specified in your Maven settings.xml

Using Tomcat

UI

To access the HTML5 UI of JahSpotify, simply point your browser to:

http://localhost:8080/jahspotify/index.html

REST API

Once running, Jah'Spotify exposes it's RESTful API

http://localhost:8080/jahspotify/system/status

All media can be retrieved using the Media Controller URL

http://localhost:8080/jahspotify/media/<URI>

Where the URI is any of the URIs specified below, in the more specialized controllers:
