Features

• Access Metadata: Retrieve detailed metadata from the MusicBrainz database.
• Submit metadata: Easily submit new metadata to MusicBrainz.
• Smart throttling: Implements intelligent throttling, allowing bursts of requests while adhering to MusicBrainz rate limits.
• TypeScript Definitions: Fully typed with built-in TypeScript definitions for a seamless development experience.

Compatibility

Module: version 8 migrated from CommonJS to pure ECMAScript Module (ESM). The distributed JavaScript codebase is compliant with the ECMAScript 2020 (11th Edition) standard.

[!NOTE] See also CommonJS backward compatibility

Requirements

Getting Started

Identifying Your Application

MusicBrainz requires all API clients to identify their application. Ensure you set the User-Agent header by providing appName, appVersion, and appContactInfo when configuring the client. This library will automatically handle this for you.

Submitting metadata

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

Example Usage

Importing the Library

import { MusicBrainzApi } from 'musicbrainz-api';

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

Accessing MusicBrainz Data

The MusicBrainz API allows you to look up various entities. Here’s how to use the lookup function:

Lookup MusicBrainz Entities

Search (query)

Implements XML Web Service/Version 2/Search.

There are different search fields depending on the entity.

Search function

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

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.search('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');

Example: search artist by artist name

Search artist:

const result = await mbApi.search('artist', {query: 'Stromae'});

Example: search release-group by artist name

Search release-group:

const result = await mbApi.search('release-group', {query: 'Racine carrée'});

Example: search release-group by release-group and an artist

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

const result = await mbApi.search('release-group', {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 has side effect.

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

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

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

Cover Art Archive API

This library also supports the Cover Art Archive API.

Fetch Release Cover Art

import { CoverArtArchiveApi } from 'musicbrainz-api';

const coverArtArchiveApiClient = new CoverArtArchiveApi();

async function getReleaseCoverArt(releaseMbid, coverType = '') {
    try {
        const coverInfo = await coverArtArchiveApiClient.getReleaseCovers(releaseMbid, coverType);
        console.log(`Cover info for ${coverType || 'all covers'}`, coverInfo);
    } catch (error) {
        console.error(`Failed to fetch ${coverType || 'all covers'}:`, error);
    }
}

(async () => {
    const releaseMbid = 'your-release-mbid-here';  // Replace with actual MBID
    await getReleaseCoverArt(releaseMbid); // Get all covers
    await getReleaseCoverArt(releaseMbid, 'front'); // Get best front cover
    await getReleaseCoverArt(releaseMbid, 'back'); // Get best back cover
})();

Release Group Cover Art

import { CoverArtArchiveApi } from 'musicbrainz-api';

const coverArtArchiveApiClient = new CoverArtArchiveApi();

async function getCoverArt(releaseGroupMbid, coverType = '') {
    try {
        const coverInfo = await coverArtArchiveApiClient.getReleaseGroupCovers(releaseGroupMbid, coverType);
        console.log(`Cover info for ${coverType || 'all covers'}`, coverInfo);
    } catch (error) {
        console.error(`Failed to fetch ${coverType || 'all covers'}:`, error);
    }
}

(async () => {
    const releaseGroupMbid = 'your-release-group-mbid-here';  // Replace with actual MBID
    await getCoverArt(releaseGroupMbid); // Get all covers
    await getCoverArt(releaseGroupMbid, 'front'); // Get best front cover
    await getCoverArt(releaseGroupMbid, 'back'); // Get best back cover
})();

CommonJS backward compatibility

For legacy CommonJS projects needing to load the music-metadata ESM module, you can use the loadMusicMetadata function:

const { loadMusicBrainzApi } = require('musicbrainz-api');

(async () => {

    // Dynamically loads the ESM module in a CommonJS project
    const  {MusicBrainzApi} = await loadMusicBrainzApi();

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

    const releaseList = await mbApi.search('release', {query: {barcode: 602537479870}});
    for(const release of releaseList.releases) {
        console.log(release.title);
    }
})();

[!NOTE] The loadMusicMetadata function is experimental.
