TDLib Native

Why use this package?

• Fast. TDLib is a fastest way to interact with Telegram on NodeJS. It's written in C++ with optimized network stack and caching.

  API Type	Package	Method	Time
  TDLib	tdl	getChat	21ms
  Telegram API	telegram (gram.js)	messages.getChats	40ms
  Telegram Bot API	telegraf	getChat	30ms

• Better DX. Unlike tdl this package declarations use dictionary for methods instead of intersection type, making editor hints load almost immediate.

• Secure. The library has only 1 dependency - node-addon-api for building TDLib addon (and platform-dependent prebuilt tdlib)

📦 Installation

• Using npm

  npm i tdlib-native

• Using Yarn

  yarn add tdlib-native

• Using pnpm

  pnpm add tdlib-native

⚙️ Usage

This is raw wrapper of TDLib

import { Client, Authenticator } from "tdlib-native";
import { TDLibAddon } from "tdlib-native/addon";

async function init() {
  // Loading addon
  const adapter = await TDLibAddon.create();

  // Make TDLib shut up. Immediately
  Client.execute(adapter, "setLogVerbosityLevel", {
    new_verbosity_level: 0
  });

  const client = new Client(adapter);
  const authenticator = Authenticator.create(client)
    .tdlibParameters({
      /* options */
    })
    .token(process.env.TELEGRAM_BOT_TOKEN);

  // Start polling responses from TDLib
  client.start();
  await authenticator.authenticate();
  // client authorized as bot

  // Call any tdlib method
  await client.api.getOption({ name: "version" });
  // => Promise { _: "optionValueString", value: "1.8.22" }

  // or use a wrapper
  await client.tdlibOptions.get("version");
  // => Promise "1.8.22"

  // Subscribe to updates
  client.updates.subscribe(console.log);

  // Pause receiving updates. Will freeze method all running API calls
  // client.pause();
  // Resume pause
  // client.start();

  // Destroy
  await client.api.close({});
  client.destroy();
}

Usage with RxJS

// Observable will complete after client.destroy() call
const updates = new Observable(client.updates.toRxObserver());
