musicbrainz-api

musicbrainz-api

A MusicBrainz-API-client for reading and submitting metadata

Features

• Access metadata from MusicBrainz
• Submit metadata
• Smart and adjustable throttling, like MusicBrainz, it allows a bursts of requests
• Build in TypeScript definitions

Before using this library

MusicBrainz asks that you identifying your application by filling in the 'User-Agent' Header. By passing appName, appVersion, appMail musicbrainz-api takes care of that.

Submitting metadata

If you plan to use this module for submitting metadata, please ensure you comply with the MusicBrainz Code of conduct/Bots.

Example

Import the module JavaScript example, how to import 'musicbrainz-api:

const MusicBrainzApi = require('musicbrainz-api').MusicBrainzApi;

const mbApi = new MusicBrainzApi({
  appName: 'my-app',
  appVersion: '0.1.0',
  appContactInfo: '[e-mail]'
});

In TypeScript you it would look like this:

import {MusicBrainzApi} from 'musicbrainz-api';

const mbApi = new MusicBrainzApi({
  appName: 'my-app',
  appVersion: '0.1.0',
  appContactInfo: '[e-mail]' // Or URL to application home page
});

The following configuration settings can be passed

import {MusicBrainzApi} from '../src/musicbrainz-api';

const config = {
  // MusicBrainz bot account username & password (optional)
  botAccount: { 
    username: 'myUserName_bot',
    password: 'myPassword' 
  },
  
  // API base URL, default: 'https://musicbrainz.org' (optional)
  baseUrl: 'https://musicbrainz.org',

  appName: 'my-app',
  appVersion: '0.1.0',

  // Optional, default: no proxy server
  proxy: {
    host: 'localhost',
    port: 8888
   },

  // Your e-mail address, required for submitting ISRCs
  appMail: string
}

const mbApi = new MusicbrainzApi(config);

Lookup MusicBrainz Entities

MusicBrainz API documentation: XML Web Service/Version 2 Lookups

Generic lookup function

Arguments:

• entity: 'artist' | 'label' | 'recording' | 'release' | 'release-group' | 'work' | 'area' | 'url'
• MBID (MusicBrainz identifier)

const artist = await mbApi.getEntity('artist', {query: 'ab2528d9-719f-4261-8098-21849222a0f2'});

Lookup area

const area = await mbApi.getArea({query: 'ab2528d9-719f-4261-8098-21849222a0f2'});

Lookup artist

Lookup an artist and include their releases, release-groups and aliases

const artist = await mbApi.getArtist({query: 'ab2528d9-719f-4261-8098-21849222a0f2'});

or use the browse API:

const artist = await mbApi.getArtist({artist: 'ab2528d9-719f-4261-8098-21849222a0f2'});

The second argument can be used to pass subqueries, which will return more (nested) information:

const artist = await mbApi.getArtist('ab2528d9-719f-4261-8098-21849222a0f2', ['releases', 'recordings', 'url-rels']);

Lookup recording

The second argument can be used to pass subqueries:

const artist = await mbApi.getRecording({query: '16afa384-174e-435e-bfa3-5591accda31c'}, ['artists', 'url-rels']);

Lookup release

const release = await mbApi.getRelease({query: '976e0677-a480-4a5e-a177-6a86c1900bbf'}, ['artists', 'url-rels']);

Lookup release-group

const releaseGroup = await mbApi.getReleaseGroup({query: '19099ea5-3600-4154-b482-2ec68815883e'});

Lookup work

const work = await mbApi.getWork({query: 'b2aa02f4-6c95-43be-a426-aedb9f9a3805'});

Search (query)

Implements XML Web Service/Version 2/Search.

There are different search fields depending on the entity.

Generic search function

Searches can be performed using the generic search function: query(entity: mb.EntityType, query: string | IFormData, offset?: number, limit?: number)

Arguments:

• Entity type, which can be one of:
  • artist: search fields
  • label: search fields
  • recording: search fields
  • release: search fields
  • release-group: search fields
  • work: search fields
  • area: search fields
  • url: search fields
• query {query: string, offset: number, limit: number}
  • query.query: supports the full Lucene Search syntax; you can find a detailed guide at Lucene Search Syntax. For example, you can set conditions while searching for a name with the AND operator.
  • query.offset: optional, return search results starting at a given offset. Used for paging through more than one page of results.
  • limit.query: optional, an integer value defining how many entries should be returned. Only values between 1 and 100 (both inclusive) are allowed. If not given, this defaults to 25.

For example, to find any recordings of 'We Will Rock You' by Queen:

const query = 'query="We Will Rock You" AND arid:0383dadf-2a4e-4d10-a46a-e9e041da8eb3';
const result = await mbApi.query<mb.IReleaseGroupList>('release-group', {query});

Example: search Île-de-France

 mbApi.search('area', 'Île-de-France');

Example: search release by barcode

Search a release with the barcode 602537479870:

 mbApi.search('release', {query: {barcode: 602537479870}});

Example: search by object

Same as previous example, but automatically serialize parameters to search query

 mbApi.search('release', 'barcode: 602537479870');

Entity specific search functions

The following entity specific search functions are available:

searchArtist(query: string | IFormData, offset?: number, limit?: number): Promise<mb.IArtistList>
searchReleaseGroup(query: string | IFormData, offset?: number, limit?: number): Promise<mb.IReleaseGroupList>`

Search artist:

const result = await mbApi.searchArtist({query: 'Stromae'});

Search release-group:

const result = await mbApi.searchReleaseGroup({query: 'Racine carrée'});

Search a combination of a release-group and an artist.

const result = await mbApi.searchReleaseGroup({artist: 'Racine carrée', releasegroup: 'Stromae'});

Submitting data via XML POST

Submitting data via XML POST may be done using personal MusicBrainz credentials.

Submit ISRC code using XML POST

Using the XML ISRC submission API.

const mbid_Formidable = '16afa384-174e-435e-bfa3-5591accda31c';
const isrc_Formidable = 'BET671300161';

const xmlMetadata = new XmlMetadata();
const xmlRecording = xmlMetadata.pushRecording(mbid_Formidable);
xmlRecording.isrcList.pushIsrc(isrc_Formidable);
await mbApi.post('recording', xmlMetadata);

Submitting data via user form-data

For all of the following function you need to use a dedicated bot account.

Submitting ISRC via post user form-data

Use with caution, and only on a test server, it may clear existing metadata as side effect.

const mbid_Formidable = '16afa384-174e-435e-bfa3-5591accda31c';
const isrc_Formidable = 'BET671300161';

    
const recording = await mbApi.getRecording(mbid_Formidable);

// Authentication the http-session against MusicBrainz (as defined in config.baseUrl)
const succeed = await mbApi.login();
assert.isTrue(succeed, 'Login successful');

// To submit the ISRC, the `recording.id` and `recording.title` are required
await mbApi.addIsrc(recording, isrc_Formidable);

Submit recording URL

const recording = await mbApi.getRecording('16afa384-174e-435e-bfa3-5591accda31c');

const succeed = await mbApi.login();
assert.isTrue(succeed, 'Login successful');

await mbApi.addUrlToRecording(recording, {
  linkTypeId: LinkType.stream_for_free,
  text: 'https://open.spotify.com/track/2AMysGXOe0zzZJMtH3Nizb'
});

Actually a Spotify-track-ID can be submitted easier:

const recording = await mbApi.getRecording('16afa384-174e-435e-bfa3-5591accda31c');

const succeed = await mbApi.login();
assert.isTrue(succeed, 'Login successful');
await mbApi.addSpotifyIdToRecording(recording, '2AMysGXOe0zzZJMtH3Nizb');

Compatibility

The JavaScript in runtime is compliant with ECMAScript 2017 (ES8). Requires Node.js® version 6 or higher.
