@passimx/archiver

Simple SDK for archiving Telegram bot events and chats using Telegraf.

Installation

npm install @passimx/archiver

Requirements

• Node.js >= 18 (uses native fetch)
• telegraf >= 4

Getting API Key

You can obtain an API key via Telegram bot:

@keep_chats_bot

Send command:

/verify <your_bot_token>

After verification you will receive your API key.

⚠️ Security recommendation

After connecting, it is strongly recommended to revoke your Telegram bot token via @BotFather:

👉 /revoke (в @BotFather)

This will invalidate the old token and protect your bot.

Usage

import { Telegraf } from 'telegraf';
import { Archiver } from '@passimx/archiver';

const bot = new Telegraf(process.env.BOT_TOKEN!);

const archiver = new Archiver({
  apiKey: 'YOUR_API_KEY',
  // endpoint is optional
});

// Start listening and sending events
archiver.listen(bot);

bot.start((ctx) => ctx.reply('Hello'));
bot.launch();

Export chat

const chat = await archiver.exportChat(123456);

console.log(chat);

What it does

• Forwards all incoming Telegram updates to your API
• Intercepts outgoing Telegram API calls (send*, edit*) by patching Telegraf internals
• Sends all events to your backend for storage or processing
• Provides chat export via API

API

new Archiver(options)

| Option | Type | Description | | -------- | ------ |-------------------------| | apiKey | string | Authorization key | | endpoint | string | API base URL (optional) |

If endpoint is not provided, a default value will be used.

archiver.listen(bot)

• incoming updates
• outgoing messages

archiver.exportChat(id)

Promise<ChatInterface | null>

Notes

• This library patches Telegraf internally
• Errors are logged to console
• Make sure your API is available and accepts requests
