When to Use

• You have rendered an MP4 video (especially 1080x1920 9:16 vertical reels) and want to immediately deliver it to Telegram.
• You want an interactive Telegram bot where users can request reels on-demand.
• You want automated pipeline delivery after video rendering finishes.

Prerequisites

• Node.js 18+ (uses native fetch, FormData, and Blob).
• A Telegram Bot Token from @BotFather.
• A target chat_id (obtained automatically when a user clicks /start).

Configuration: telegram_config.json

{
  "bot_token": "YOUR_BOT_TOKEN_HERE",
  "chat_id": "YOUR_CHAT_ID_HERE",
  "bot_name": "Peak Lyrics",
  "bot_username": "PeakLyricsBot",
  "auto_upload": true
}

Setup & Automated Linking

Run the setup script with your bot token:

node setup_telegram.js <YOUR_BOT_TOKEN>

1. Verifies the token with getMe.
2. Prints your bot link (https://t.me/<bot_username>).
3. Waits for the user to press /start in Telegram.
4. Captures and saves the chat_id automatically to telegram_config.json.
5. Immediately delivers pending reels.

Direct API Upload Workflow

const fs = require('fs');
const path = require('path');

async function sendReelVideo(videoPath, { day, songTitle }, chatId, botToken) {
  const blob = await fs.openAsBlob(videoPath);
  const form = new FormData();
  form.append('chat_id', chatId);
  form.append('video', blob, path.basename(videoPath));
  form.append('caption', `🎬 <b>Day ${day}</b>: <i>${songTitle}</i>\n✨ 1080x1920 Studio Quality\n⏱ Word-by-word synced`);
  form.append('parse_mode', 'HTML');
  form.append('supports_streaming', 'true');
  form.append('width', '1080');
  form.append('height', '1920');

  const res = await fetch(`https://api.telegram.org/bot${botToken}/sendVideo`, {
    method: 'POST',
    body: form
  });
  return await res.json();
}

node telegram_bot.js listen

• /start or /help - Overview and menu
• /day1 - Delivers Day 1 Reel
• /day2 - Delivers Day 2 Reel
