Telegram Bot with Cloudflare Worker

Welcome to the Telegram Bot project! This guide will walk you through creating and deploying a Telegram bot using Cloudflare Workers.

Features

• Webhook Management: Set and remove webhooks easily.
• Interactive Commands: Respond to user commands with inline buttons.
• Message Handling: Send, edit, and delete messages based on user interactions.

Prerequisites

• A Telegram account and a bot created using the BotFather.
• A Cloudflare account to host the worker.

Setup Instructions

Step 1: Create a Telegram Bot

1. Open Telegram and search for BotFather.
2. Start a chat and use the command /newbot to create a new bot.
3. Follow the prompts to set your bot's name and username.
4. After creation, you will receive a token. Save it for later.

Step 2: Create a Cloudflare Worker

1. Log in to your Cloudflare account.
2. Go to the Workers section and create a new worker.
3. Replace the default code with the code provided below.

Step 3: Update the Code

Replace the YOUR_TELEGRAM_BOT_TOKEN and your-cloudflare-worker-url.workers.dev placeholders in the code with your actual bot token and the Cloudflare Worker URL.

const TOKEN = 'YOUR_TELEGRAM_BOT_TOKEN'; // Ganti dengan token bot Anda
const API_URL = `https://api.telegram.org/bot${TOKEN}`;
const WEBHOOK_URL = 'https://your-cloudflare-worker-url.workers.dev'; // Ganti dengan URL Cloudflare Worker Anda

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});

// ... (rest of your code)

Step 4: Deploy the Webhook

To set the webhook for your bot, send a GET request to the following URL:

https://api.telegram.org/botYOUR_TELEGRAM_BOT_TOKEN/setWebhook?url=https://your-cloudflare-worker-url.workers.dev

You can use a tool like Postman or your browser to make this request.

Step 5: Test Your Bot

1. Open Telegram and start a chat with your bot.
2. Type /start to see the bot's response.
3. Interact with the buttons to test sending, editing, and deleting messages.
