Telegram Bot Builder

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.

Bot Architecture

Stack Options

Basic Telegraf Setup

```javascript 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

```python

Inline Keyboards

Basic Keyboard

```javascript 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

```javascript

Bot Monetization

Revenue Models

Telegram Payments

```javascript // 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.
