genius_lyrics: a Dart client for the Genius.com API based on LyricsGenius

genius_lyrics provides a simple interface to the song, artist, and lyrics data stored on Genius.com.

Read the API reference here.

Setup

Before using this package you'll need to sign up for a (free) account that authorizes access to the Genius API. The Genius account provides a accessToken that is required by the package. See the Usage section below for examples.

Usage

Import the package and initiate Genius:

import 'package:genius_lyrics/genius_lyrics.dart';
Genius genius = Genius(accessToken: 'YOUR_TOKEN');

Search for songs by a given artist:

Artist? artist = await genius.searchArtist(artistName: 'Eminem', maxSongs: 5, sort: SongsSorting.release_date);
if (artist != null) {
  for (var song in artist.songs) {
    print(song.title);
  }
}

By default, the searchArtist() only returns songs where the given artist is the primary artist. However, there may be instances where it is desirable to get all of the songs that the artist appears on. You can do this by setting the includeFeatures argument to true.

Artist? artist = await genius.searchArtist(artistName: 'Eminem', maxSongs: 5, includeFeatures: true);
if (artist != null) {
  for (var song in artist.songs) {
    print(song.title);
  }
}

Search for a single song by the same artist:

artist?.song(client: genius, songName: "No Love");
# or:
# Song? song = genius.searchSong(artist: 'Eminem', title: 'No Love'));
if (song != null) {
  print(song.lyrics);
}

Add the song to the artist object:

artist?.addSong(newSong: song!);

Save the artist's songs to a file:

artist?.saveLyrics(destPath: 'D:/Music/Eminme/Lyrics');

Searching for an album and saving it:

Album? album = (await genius.searchAlbum(name: 'The Off-Season', artist: 'J.Cole'));
album?.saveLyrics(destPath: 'D:/Desktop/test');

A complete example

import 'package:genius_lyrics/genius_lyrics.dart';

void main(List<String> args) async {
  Genius genius = Genius(
    accessToken: const String.fromEnvironment('GENIUS_TOKEN'),
  );

  Artist? artist = await genius.searchArtist(
    artistName: 'Eminem',
    maxSongs: 5,
    sort: SongsSorting.release_date,
    includeFeatures: true,
  );

  if (artist != null) {
    for (var song in artist.songs) {
      print(song.title);
    }
  }

  Album? album = (await genius.searchAlbum(name: 'The Off-Season', artist: 'J.Cole'));
  album?.saveLyrics(destPath: 'D:/Desktop/test');

  if (album != null) {
      print(album.tracks.length);
      for (var track in album.tracks) {
        print(track.title);
      }
  }

  Song? song = (await genius.searchSong(artist: 'J. Cole', title: 'KOD'));

  if (song != null) {
    print(song.lyrics);
  }
}

Environment Variables

To run this project test suit, you need to have your Genius token as an environment variable called GENIUS_TOKEN. You can set this in many ways.

If you have Flutter installed, you can run the test suit with:

flutter test --dart-define=GENIUS_TOKEN=<your token>

Also with Flutter, it's possible to create a .env file, as the .env.example, and run:

flutter test --dart-define-from-file=.env

If you don't have Flutter installed, or wish to run with Dart only, the command is a little more complex:

dart --define=GENIUS_TOKEN=<your token> test -c vm:source

It's also possible to add these configurations on your IDE configuration file. Here's an example for VS Code, on .vscode/launch.json:

{
  "configurations": [
    {
      "name": "Dart: Run all Tests",
      "type": "dart",
      "request": "launch",
      "vmAdditionalArgs": ["--define=GENIUS_TOKEN=<your token>"],
      "toolArgs": ["-c vm:source"],
      "program": "./test/"
    }
  ]
}
