Electron Media Service

This is an easy way to get OS level media integration cross-platform in Electron, it hooks into the following system API's.

| Platform | API | Requirements | |----------|-----|--------------| | darwin | MPRemoteCommandCenter and MPNowPlayingInfoCenter | macOS 10.12.1+ | | win32 Coming Soon | MediaTransportControls | Windows 10+ | | linux Coming Soon | DBus | Well... DBus :D |

All you have to do to get all this awesome for you is

import MediaService from 'electron-media-service';

const myService = new MediaService();

myService.startService();
myService.on('play', () => playSomething());
myService.on('pause', () => pauseSomething());
myService.setMetaData({
  title: 'Never Gonna Give You Up',
  // Other track meta data here
});

What does it look like?

Methods

myService.startService()

Starts the media service my registering the application with the system, no other methods or events will work until this method is called. It's a good idea to give users an option to not start the service as it can be annoying for some users especially on Windows 10.

myService.stopService()

Attempts to unregister the service from the system, sometimes a full relaunch is required to unregister an application but this method tries it's hardest.

myService.isStarted()

Returns Boolean, whether the service is started yet or not. If you forget whether you started it or not you can always call this method to check.

myService.setMetaData(meta)

• meta Object - The current tracks MetaData
  • title String - The title of the track
  • artist String - The name of the artist
  • album String - The name of the album
  • albumArt String - HTTP url to an image for the album art
  • state String - One of playing, paused or stopped
  • id Number - A unique ID for this track, can be randomly generated as it doesn't really affect anything
  • currentTime Number - Progress through the track in milliseconds
  • duration Number - Total length of the track in milliseconds

Events

myService.on('play')

Fired when the user or the system requests the track to start playing

myService.on('pause')

Fired when the user or the system requests the track to pause

myService.on('playPause')

Fired when the user or the system requests the track to toggle between playing and paused

myService.on('next')

Fired when the user or the system requests the player to skip to the next track

myService.on('previous')

Fired when the user or the system requests the player to skip back to the previous track

myService.on('seek')

Fired when the user or the system requests the player to seek through the track to the given time.

The target time will be given in milliseconds as the first argument to the event like so.

myService.on('seek', (to) => {
  console.log(`We should seek to ${to}ms`)
})

What happens on unsupported platforms?

We automatically give you a noop MediaService class, all methods do nothing and no events are ever fired. This allows you to not worry about supported platforms and just write code. Call whatever methods you want and nothing will break.
