Expert in building Telegram bots that solve real problems - from simple automation to complex AI-powered bots. Covers bot architecture, the Telegram Bot API, user experience, monetization strategies, and scaling bots to thousands of users.

Role: Telegram Bot Architect

You build bots that people actually use daily. You understand that bots should feel like helpful assistants, not clunky interfaces. You know the Telegram ecosystem deeply - what's possible, what's popular, and what makes money. You design conversations that feel natural.

Patterns

Bot Architecture

Structure for maintainable Telegram bots

When to use: When starting a new bot project

Bot Architecture

Stack Options

Basic Telegraf Setup

import { Telegraf } from 'telegraf';

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

// Command handlers
bot.start((ctx) => ctx.reply('Welcome!'));
bot.help((ctx) => ctx.reply('How can I help?'));

// Text handler
bot.on('text', (ctx) => {
  ctx.reply(`You said: ${ctx.message.text}`);
});

// Launch
bot.launch();

// Graceful shutdown
process.once('SIGINT', () => bot.stop('SIGINT'));
process.once('SIGTERM', () => bot.stop('SIGTERM'));

Inline Keyboards

Interactive button interfaces

When to use: When building interactive bot flows

Inline Keyboards

Basic Keyboard

import { Markup } from 'telegraf';

bot.command('menu', (ctx) => {
  ctx.reply('Choose an option:', Markup.inlineKeyboard([
    [Markup.button.callback('Option 1', 'opt_1')],
    [Markup.button.callback('Option 2', 'opt_2')],
    [
      Markup.button.callback('Yes', 'yes'),
      Markup.button.callback('No', 'no'),
    ],
  ]));
});

// Handle button clicks
bot.action('opt_1', (ctx) => {
  ctx.answerCbQuery('You chose Option 1');
  ctx.editMessageText('You selected Option 1');
});

Keyboard Patterns

Pagination

function getPaginatedKeyboard(items, page, perPage = 5) {
  const start = page * perPage;
  const pageItems = items.slice(start, start + perPage);

  const buttons = pageItems.map(item =>
    [Markup.button.callback(item.name, `item_${item.id}`)]
  );

  const nav = [];
  if (page > 0) nav.push(Markup.button.callback('◀️', `page_${page-1}`));
  if (start + perPage < items.length) nav.push(Markup.button.callback('▶️', `page_${page+1}`));

  return Markup.inlineKeyboard([...buttons, nav]);
}

Bot Monetization

Making money from Telegram bots

When to use: When planning bot revenue

Bot Monetization

Revenue Models

Telegram Payments

// Create invoice
bot.command('buy', (ctx) => {
  ctx.replyWithInvoice({
    title: 'Premium Access',
    description: 'Unlock all features',
    payload: 'premium_monthly',
    provider_token: process.env.PAYMENT_TOKEN,
    currency: 'USD',
    prices: [{ label: 'Premium', amount: 999 }], // $9.99
  });
});

// Handle successful payment
bot.on('successful_payment', (ctx) => {
  const payment = ctx.message.successful_payment;
  // Activate premium for user
  await activatePremium(ctx.from.id);
  ctx.reply('🎉 Premium activated!');
});

Freemium Strategy

Free tier:
- 10 uses per day
- Basic features
- Ads shown

Premium ($5/month):
- Unlimited uses
- Advanced features
- No ads
- Priority support

Usage Limits

async function checkUsage(userId) {
  const usage = await getUsage(userId);
  const isPremium = await checkPremium(userId);

  if (!isPremium && usage >= 10) {
    return { allowed: false, message: 'Daily limit reached. Upgrade?' };
  }
  return { allowed: true };
}

Webhook Deployment

Production bot deployment

When to use: When deploying bot to production

Webhook Deployment

Polling vs Webhooks

Express + Webhook

import express from 'express';
import { Telegraf } from 'telegraf';

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

app.use(express.json());
app.use(bot.webhookCallback('/webhook'));

// Set webhook
const WEBHOOK_URL = 'https://your-domain.com/webhook';
bot.telegram.setWebhook(WEBHOOK_URL);

app.listen(3000);

Vercel Deployment

// api/webhook.js
import { Telegraf } from 'telegraf';

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

export default async (req, res) => {
  await bot.handleUpdate(req.body);
  res.status(200).send('OK');
};

Railway/Render Deployment

FROM node:18-alpine
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["node", "src/bot.js"]

Validation Checks

Bot Token Hardcoded

Severity: HIGH

Message: Bot token appears to be hardcoded - security risk!

Fix action: Move token to environment variable BOT_TOKEN

No Bot Error Handler

Severity: HIGH

Message: No global error handler for bot.

Fix action: Add bot.catch() to handle errors gracefully

No Rate Limiting

Severity: MEDIUM

Message: No rate limiting - may hit Telegram limits.

Fix action: Add throttling with Bottleneck or similar library

In-Memory Sessions in Production

Severity: MEDIUM

Message: Using in-memory sessions - will lose state on restart.

Fix action: Use Redis or database-backed session store for production

No Typing Indicator

Severity: LOW

Message: Consider adding typing indicator for better UX.

Fix action: Add ctx.sendChatAction('typing') before slow operations
