Spotify-desktop-remote NPM

Spotify Desktop Remote

Control your Spotify Desktop app from a simple HTTP interface or with Socket.IO.

# Play a track:
curl http://localhost:3001/play/spotify:track:0FutrWIUM5Mg3434asiwkp

# Seek to the halfway mark of the song:
curl http://localhost:3001/seek/0.5

# Set the player volume:
curl http://localhost:3001/volume/0.8

# Play a playlist:
curl http://localhost:3001/play/spotify:album:2YJFLMyzzZ2k4mhfPSiOj2

# Pause the player:
curl http://localhost:3001/pause

# Stop the player:
curl http://localhost:3001/stop

// Keep everything in sync:
socket.on('player.change', function (playerStatus) {
  console.log('The current player status is', playerStatus);
});

// Play a track:
socket.emit('play', {uri: 'spotify:track:0FutrWIUM5Mg3434asiwkp'});

// Seek to the halfway mark of the song:
socket.emit('seek', 0.5);

// Set the player volume:
socket.emit('volume', 0.8);

// Play a playlist:
socket.emit('play', {uri: 'spotify:album:2YJFLMyzzZ2k4mhfPSiOj2'});

// Pause the player:
socket.emit('pause');

// Stop the player:
socket.emit('stop');

See the API reference for more details.

Requirements

node.js >= 0.10
A premium Spotify account, registered as a developer.

Installation

There are two parts to the app:

The HTTP Server that forwards commands to Spotify (src/server.coffee)
The Spotify Webapp (runs inside Spotify Desktop) that accepts commands from the server via Websockets (src/main.coffee and index.html)

# OS X/Linux users:
cd ~/Spotify

# Windows users:
# cd ~/My\ Documents/Spotify

git clone https://github.com/namuol/spotify-desktop-remote.git
cd spotify-desktop-remote

# Start the server on port 3001:
npm start

# Or run it on a different port:
# PORT=3002 npm start

# Finally, run spotify and open the app:
spotify -uri spotify:app:spotify-desktop-remote

# NOTE: You can also run the app by entering
# "spotify:app:spotify-desktop-remote" into Spotify's search bar.

# Now you can control the Spotify Desktop app by hitting the server:
curl http://localhost:3001/play/spotify:track:0FutrWIUM5Mg3434asiwkp
curl http://localhost:3001/volume/1

Socket.io

In order to use socket.io, include the following in your <head>:

<script type='application/javascript' src="http://localhost:3001/socket.io/socket.io.js"></script>

Then somewhere after that you can connect:

var socket = io.connect();
socket.on('player.change', function (playerStatus) {
  console.log('The current player status is', playerStatus);
});

`socket.on('player.change', callback(playerStatus))`

socket only

Subscribe to this event to be notified whenever anything about the player changes.

To poll for the status (with sockets or GET), see sync.

socket.on('player.change', function (playerStatus) {
  console.log('The current volume level is', playerStatus.volume)
});

Parameters:

callback(playerStatus) socket only A callback function that accepts a single argument as the player's current status.

`/sync`

`socket.emit('sync', callback(playerStatus))`

Perform no action; simply used to retrieve the current status of the player.

curl http://localhost:3001/sync

socket.emit('sync', function (playerStatus) {
  console.log('The current volume level is', playerStatus.volume);
});

Parameters:

callback(playerStatus) socket only A callback function that accepts a single argument as the player's current status.

`/play`

`socket.emit('play')`

Play the current track.

curl http://localhost:3001/play

socket.emit('play');
