Patterns

Bot Architecture

Structure for maintainable Telegram bots

When to use: When starting a new bot project

## Bot Architecture

### Stack Options
| Language | Library | Best For |
|----------|---------|----------|
| Node.js | telegraf | Most projects |
| Node.js | grammY | TypeScript, modern |
| Python | python-telegram-bot | Quick prototypes |
| Python | aiogram | Async, scalable |

### 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'));

### Project Structure

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
| Pattern | Use Case |
|---------|----------|
| Single column | Simple menus |
| Multi column | Yes/No, pagination |
| Grid | Category selection |
| URL buttons | Links, payments |

### 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
| Model | Example | Complexity |
|-------|---------|------------|
| Freemium | Free basic, paid premium | Medium |
| Subscription | Monthly access | Medium |
| Per-use | Pay per action | Low |
| Ads | Sponsored messages | Low |
| Affiliate | Product recommendations | Low |

### 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 }; }

Anti-Patterns

❌ Blocking Operations

Why bad: Telegram has timeout limits. Users think bot is dead. Poor experience. Requests pile up.

Instead: Acknowledge immediately. Process in background. Send update when done. Use typing indicator.

❌ No Error Handling

Why bad: Users get no response. Bot appears broken. Debugging nightmare. Lost trust.

Instead: Global error handler. Graceful error messages. Log errors for debugging. Rate limiting.

❌ Spammy Bot

Why bad: Users block the bot. Telegram may ban. Annoying experience. Low retention.

Instead: Respect user attention. Consolidate messages. Allow notification control. Quality over quantity.
