# Keyboard Reset Bot

A minimal Telegram bot that removes reply keyboard buttons in Telegram group chats by sending a keyboard reset message.

## Features

- Works only in group chats and supergroups
- Single command: `/resetkeyboard`
- Admin-only authorization
- Automatically removes its confirmation message after 7 seconds
- Stateless (no database, no data storage)

## Setup

1. **Get a Bot Token**
   - Talk to [@BotFather](https://t.me/botfather) on Telegram
   - Create a new bot with `/newbot`
   - Copy the bot token

2. **Install Dependencies**
   ```bash
   npm install
   ```

3. **Configure Environment**
   - Copy `.env.example` to `.env`
   - Add your bot token:
     ```
     BOT_TOKEN=your_bot_token_here
     ```

4. **Run the Bot**
   ```bash
   npm start
   ```

## Usage

1. Add the bot to your Telegram group
2. Grant the bot "Read messages" permission (and optionally "Delete messages" for cleanup)
3. An admin can use `/resetkeyboard` to remove all reply keyboards in the group

## Requirements

- Node.js 14+ (ES modules support)
- Bot permissions: "Read messages" (required), "Delete messages" (optional)

## How It Works

When an admin sends `/resetkeyboard` in a group:
1. The bot verifies the user is an administrator
2. Sends a message with `ReplyKeyboardRemove` (selective: false)
3. This resets reply keyboards for all users who receive the message
4. The bot deletes its own message after 7 seconds

## Notes

- The bot ignores private chats
- Only group administrators can use the command
- The bot is stateless and does not store any data
- If another bot sends a keyboard after reset, it will appear again (expected behavior)
