    A TypeScript SDK for Jellyfin.

    Warning: This project is under active development, so API changes may occur.


    npm i --save @thornbill/jellyfin-sdk


    yarn add @thornbill/jellyfin-sdk

    Supported Jellyfin Versions

    SDK Version Jellyfin Version
    0.5.0 10.8.x
    <0.5.0 10.7.x

    React Native

    The generated Axios client used in this library depends on URL and URLSearchParams to be available on the global scope. React Native only includes incomplete implementations for these classes, so a polyfill is required. React Native URL Polyfill seems like a good solution for this.


    // Create a new instance of the SDK
    const jellyfin = new Jellyfin({
        clientInfo: {
            name: 'My Client Application',
            version: '1.0.0'
        deviceInfo: {
            name: 'Device Name',
            id: 'unique-device-id'
    // Find a valid server by trying to connect using common protocols and ports.
    // Each server receives a score based on security, speed, and other criteria.
    const servers = await jellyfin.discovery.getRecommendedServerCandidates('');
    // A utility function for finding the best result is available.
    // If there is no "best" server, an error message should be displayed.
    const best = jellyfin.discovery.findBestServer(servers);
    // Create an API instance
    const api = jellyfin.createApi(best.address);
    // Each API endpoint is exposed via a getter on the SDK instance using
    // a shared Configuration and Axios instance. For example the /System APIs
    // are available as api.systemApi.
    // Fetch the public system info
    const info = await getSystemApi(api).getPublicSystemInfo();
    console.log('Info =>',;
    // Fetch the list of public users
    const users = await getUserApi(api).getPublicUsers();
    console.log('Users =>',;
    // A helper method for authentication has been added to the SDK because
    // the default method exposed in the generated Axios client is rather
    // cumbersome to use.
    const auth = await api.authenticateUserByName('demo', '');
    console.log('Auth =>',;
    // Authentication state is stored internally in the Api class, so now
    // requests that require authentication can be made normally
    const libraries = await getLibraryApi(api).getMediaFolders();
    console.log('Libraries =>',;
    // A helper method for logging out the current user has been added to the
    // SDK so the internal state is updated correctly.
    await api.logout();

    Breaking Changes


    • Build directory is now lib instead of dist. Any imports used that were previously in dist will need updated. #147
    • Duplicated exports were removed. Any imports may need updated if you referenced one of the duplicates. #148
    • API classes are no longer exposed via getters. Instead you need to call a function passing the Api instance as a parameter. For example: getSystemApi(api). While I do feel this is a slightly worse developer experience, it was a necessary change to support tree-shaking. #149
    • BaseItemKind is now included in the generated client. Imports will need updated. #187

    Roadmap to 1.0

    • [ ] More complete device profile generation utilities
    • [ ] Use custom generator templates for API versions
    • [ ] Automate OpenAPI spec updates using GitHub
      • [ ] Create branch tracking unstable Jellyfin builds
