Full changelog

What's New

logOut() — Complete Telegram Session Termination

New method TelegramService.logOut() that calls Api.auth.LogOut() to fully terminate the session on Telegram servers.

What it does:

  • Terminates the MTProto session on Telegram's side
  • Session disappears from the user's "Active Sessions" in Telegram settings
  • Session string becomes invalid after logout
  • Graceful fallback: if remote logout fails, disconnects locally

Use case: Cloud/hosted MCP services that need to clean up Telegram sessions when a user disconnects their connector (e.g. via OAuth token revocation).

const telegram = new TelegramService(apiId, apiHash);
await telegram.connect();

// ... use the service ...

// Full logout (removes from Telegram "Active Sessions")
const success = await telegram.logOut();

// vs. soft disconnect (session remains valid for reconnect)
await telegram.disconnect();

Other improvements

  • getChatInfo now returns membersCount and description using GetFullChannel/GetFullChat API calls
  • downloadMediaAsBuffer — new method for serverless media download (returns Buffer instead of writing to disk)
  • MIME type detection — uses magic bytes (JPEG/PNG/GIF/WebP) instead of unreliable Telegram metadata
