Requires Node.js >= 24.0.0

Syno API

• DSM API (SYNO.DSM, SYNO.Core)
• File Station API (SYNO.FileStation)
• Download Station API (SYNO.DownloadStation)
• Audio Station API (SYNO.AudioStation)
• Video Station API (SYNO.VideoStation)
• Video Station DTV API (SYNO.DTV)
• Surveillance Station API (SYNO.SurveillanceStation)
• Synology Photos API (SYNO.Foto, SYNO.FotoTeam) - DSM 7.x only

For detailed parameters and response data, refer to the Synology Developer Tool page.

JavaScript / TypeScript

import { Syno } from 'syno';

const syno = new Syno({
    // Requests protocol: 'http' or 'https' (default: 'http')
    protocol: 'https',
    // DSM host: IP or domain name (default: 'localhost')
    host: 'localhost',
    // DSM port (default: 5000)
    port: 5001,
    // DSM User account (required)
    account: 'my_username',
    // DSM User password (required)
    passwd: 'my_password',
    // DSM API version (default: '7.2')
    apiVersion: '7.2',
});

All methods return Promises:

const info = await syno.fs.getInfo();

Or call a method dynamically:

const info = await syno.fs.call('getInfo', { folder_path: '/path' });

Examples

// DSM API - Provide DSM information
const dsmInfo = await syno.dsm.getInfo();

// File Station API - Provide File Station information
const fsInfo = await syno.fs.getInfo();

// File Station API - Enumerate files in a given folder
const files = await syno.fs.list({ folder_path: '/path/to/folder' });

// Download Station API - List download tasks
const tasks = await syno.dl.listTasks({ limit: 5, offset: 10 });

// Download Station API - Create a download task
await syno.dl.createTask({ uri: 'https://link' });

// Audio Station API - Search a song
const songs = await syno.as.searchSong({ title: 'my_title_song' });

// Video Station API - List movies
const movies = await syno.vs.listMovies({ limit: 5 });

// Video Station DTV API - List channels
const channels = await syno.dtv.listChannels({ limit: 5 });

// Surveillance Station API - Get camera information
const camera = await syno.ss.getInfoCamera({ cameraIds: 4 });

// Synology Photos API (DSM 7.x) - List albums
const albums = await syno.photo.listAlbums();

Migrating from 2.x to 3.x

Breaking changes

• Async/await only — All methods now return Promises. Callbacks are no longer supported.

  // Before (2.x)
  syno.fs.getInfo(function(err, data) { ... });
  // After (3.x)
  const data = await syno.fs.getInfo();

• Node.js 24+ required — Uses native fetch, no polyfills needed.
• Browser support removed — Node.js only. Browser bundles are no longer shipped.
• Default API version changed from 6.0.2 to 7.2.
• DSM 5.x support dropped — Only 6.x and 7.x definitions are included.
• ESM + CJS dual output — import { Syno } from 'syno' or const { Syno } = require('syno').
• TypeScript types included — No separate @types package needed.

Tips & Tricks

If you encounter certificate errors with https:

[ERROR] : Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE

Use the --ignore-certificate-errors flag:

$ syno fs getInfo --ignore-certificate-errors

Or set the environment variable:

export SYNO_IGNORE_CERTIFICATE_ERRORS=1

Or in code:

const syno = new Syno({
    ignoreCertificateErrors: true,
    // ...
});
