API

subsonic-api supports all of the Subsonic API methods as documented here, up to API version 1.16.1 / Subsonic 6.1.4. Additionally, most of OpenSubsonic's new API methods are also supported. All methods return a promise that resolves to the JSON response from the server.

Additionally, the following methods are available:

interface SubsonicConfig {
  // The base URL of the Subsonic server, e.g., https://demo.navidrome.org.
  url: string;

  // The authentication details to use when connecting to the server.
  auth: {
    username: string;
    password: string;
  };

  // A salt to use when hashing the password
  salt?: string;

  // Whether to reuse generated salts. If not provided,
  // a random salt will be generated for each request.
  // Ignored if `salt` is provided.
  reuseSalt?: boolean;

  // Whether to use a POST requests instead of GET requests.
  // Only supported by OpenSubsonic compatible servers with the `formPost` extension.
  post?: boolean;

  // The fetch implementation to use. If not provided, the global fetch will be used.
