🎯 What does this library do?

In countries like Iran where api.telegram.org is network-filtered, developers need a VPN or a foreign server to run their Telegram bots.

andro-cfw solves this with a simple trick: it deploys a Cloudflare Worker as a reverse proxy between your bot and Telegram:

Your Bot (Python / JS / PHP)  ←→  Cloudflare Worker (unfiltered)  ←→  api.telegram.org

Cloudflare's edge network is reachable from restricted regions even when Telegram's API is not, so your bot talks to the Worker and the Worker talks to Telegram.

📖 Complete Guide: 100% Serverless Telegram Bots on Cloudflare

You can run your Telegram bot 100% serverless on Cloudflare Edge with 24/7 uptime, ~5ms response latency, and zero server costs (using Cloudflare's free 100,000 requests/day tier).

---

Method A: Zero-Code 1-Command Serverless Bot (andro-cfw serverless)

Deploy a fully functional 24/7 serverless bot in under 30 seconds:

1. Run the deployment command:

   andro-cfw serverless
   

2. Enter your Telegram Bot Token from @BotFather when prompted:

   [andro-cfw] Enter your Telegram Bot Token from @BotFather: 7123456789:AAFgX...
   

3. Done! andro-cfw will deploy the Cloudflare Worker, configure the Webhook, and register it with Telegram automatically — with zero VPN required.

Built-in Serverless Commands:

• /start or /help — Welcome card with edge performance & latency metrics.
• /ping — Responds with pong 🏓 (< 5ms Edge Latency).
• /status — Displays live Cloudflare Worker status & health.
• /echo <text> — Echoes back any text message.

Method B: Full Custom TypeScript / JavaScript Worker Bot

If you want to build a full custom serverless bot with interactive buttons, database calls, or custom logic in JavaScript/TypeScript:

1. worker.ts Code:

export interface Env {
  BOT_TOKEN?: string;
}

const TELEGRAM_ORIGIN = "https://api.telegram.org";

export default {
  async fetch(request: Request, env: Env): Promise<Response> {
    const url = new URL(request.url);

    // 1. Webhook Update Handler (POST /webhook)
    if (request.method === "POST" && url.pathname.includes("/webhook")) {
      try {
        // Extract token from query parameter or Env
        const token = url.searchParams.get("token") || env.BOT_TOKEN;
        const update = (await request.json()) as any;

        if (update && update.message && update.message.text && token) {
          const chatId = update.message.chat.id;
          const text = update.message.text.trim();

          let replyText = "";

          // Custom Bot Command Logic
          if (text === "/start") {
            replyText = "👋 Hello! I am running 100% Serverless on Cloudflare Edge!";
          } else if (text === "/ping") {
            replyText = "🏓 Pong from Cloudflare Worker!";
          } else if (text.startsWith("/echo ")) {
            replyText = `📢 You said: ${text.slice(6)}`;
          } else {
            replyText = `🤖 Received your message: "${text}"`;
          }

          // Reply back to Telegram
          const replyUrl = `${TELEGRAM_ORIGIN}/bot${token}/sendMessage`;
          await fetch(replyUrl, {
            method: "POST",
            headers: { "Content-Type": "application/json" },
            body: JSON.stringify({
              chat_id: chatId,
              text: replyText,
              parse_mode: "Markdown",
            }),
          });
        }
      } catch (err) {
        console.error("Webhook processing error:", err);
      }
      return new Response("OK", { status: 200 });
    }

    // 2. Reverse Proxy Pass-through for local/external bots
    const targetUrl = TELEGRAM_ORIGIN + url.pathname + url.search;
    return fetch(targetUrl, {
      method: request.method,
      headers: request.headers,
      body: ["GET", "HEAD"].includes(request.method) ? undefined : request.body,
      // @ts-ignore
      duplex: "half",
    });
  },
};

Method C: Python Bot via 1-Line Patcher (andro_cfw.patch())

If you prefer writing your bot logic in Python using telebot, pyrogram, aiogram, or python-telegram-bot:

import telebot
import andro_cfw

# 1-Line Auto-Patcher: Routes 100% of Telegram API calls through Cloudflare Worker
session = andro_cfw.patch()

bot = telebot.TeleBot("YOUR_BOT_TOKEN_FROM_BOTFATHER")

@bot.message_handler(commands=["start", "help"])
def send_welcome(message):
    bot.reply_to(
        message,
        "🤖 **Hello from behind the filter!**\n\n"
        f"🌐 **Worker URL**: `{session.worker_url}`\n"
        "🔒 **Status**: Unfiltered & Running Smoothly!"
    )

if __name__ == "__main__":
    print(f"🚀 Bot starting behind Cloudflare Worker ({session.worker_url})...")
    bot.infinity_polling(timeout=20, long_polling_timeout=20)

---

Method D: PHP / External Webhook Backend Mode (FORWARD_WEBHOOK_URL)

If you have an existing PHP, Node.js, Python, or Go webhook bot hosted on your own server or cPanel, you can use Cloudflare Worker as a Webhook Filter Bypass:

1. In your Worker's wrangler.toml or Cloudflare Dashboard environment variables, set:

   [vars]
   FORWARD_WEBHOOK_URL = "https://your-server.com/my_bot_webhook.php"
   

2. Whenever Telegram sends a Webhook update to your Cloudflare Worker, Cloudflare automatically strips the network filter and forwards the payload straight to your PHP backend!

---

🐍 Framework Snippet Generator (andro-cfw snippet)

Generate copy-paste ready starter code for your framework:

# Print starter snippet for Telebot
andro-cfw snippet -f telebot

# Generate ready-to-run bot.py for Aiogram / Pyrogram / PTB / Hydrogram
andro-cfw snippet -f aiogram -o bot.py
andro-cfw snippet -f pyrogram -o bot.py
andro-cfw snippet -f hydrogram -o bot.py
andro-cfw snippet -f ptb -o bot.py

---

🔍 Worker Health & Latency Check (andro-cfw check)

Test live network connectivity, HTTP response code, and Keep-Alive latency (ms) across all deployed workers:

andro-cfw check

Output example:

  Worker [0]: account-1
    URL     : https://andro-cfw-12345678.workers.dev
    Status  : HTTP 200 OK (59.1 ms)
    Quota   : [available]

🔐 Security Notes

• cfw.session is encrypted with Fernet (AES-128-CBC + HMAC). Key stored in ~/.andro_cfw/key.
• Add cfw.session to .gitignore.
• The generated worker is a pure pass-through proxy: it does not log, store, or inspect bot tokens or updates.
