Last.fm Export Stream

A readable object stream of a Last.fm user's scrobble history.

Installation

npm install lastfmexportstream --save

Options

• apiKey: (required) The Last.fm API key. If you don't have one, get one from Last.fm.
• user: (required) The Last.fm username.
• reverse: (optional, default: false) By default, scrobbles are fetched in chronological order, i.e. oldest scrobble first. If reverse: true the scrobbles will be fetched in reverse order, i.e. latest scrobble first.
• from: (optional) A UTC unix timestamp in milliseconds representing the date of the earliest scrobble you want. If this option is not present the stream will start from the first scrobble.
• to: (optional) A UTC unix timestamp in milliseconds representing the date of the latest scrobble you want. If this option is not present the stream will end with the latest scrobble.
• tracksPerRequest: (optional, default: 100, max: 200) The number of tracks to be fetched per request.
• requestsPerMinute: (optional, default: 60) The maximum number of Last.fm API requests per second.
• errorDelay: (optional, default: 10000) The number of milliseconds to wait until the next request if an error occurs.

Check progress

Use the .totalTracks and .trackCount properties to check the progress of the stream.

progress = ((stream.trackCount / stream.totalTracks) * 100) + '%';

Track format

• time: A UTC unix timestamp in milliseconds. Represents the time of the scrobble.
• *MBID: The MusicBrainz ID of the track, artist or album respectively, if available.

The rest is rather self explanatory.

  title: 'Inky Dinky Wang Dang Doo',
  album: 'The Golden Torch Revisited',
  trackMBID: '2c769602-4dfe-458d-b5e6-b0895d120830',
  artistMBID: '1af3791d-816f-4e36-b475-e40d29d1c25b',
  albumMBID: '' }

Example

var through = require('through2');

});

soma7soul
  .pipe(through.obj(function (track, enc, callback) {
