Patterns
Mini App Setup
Getting started with Telegram Mini Apps
When to use: When starting a new Mini App
## Mini App Setup
### Basic Structure
<!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <script src="https://telegram.org/js/telegram-web-app.js"></script> </head> <body> <script> const tg = window.Telegram.WebApp; tg.ready(); tg.expand();
// User data const user = tg.initDataUnsafe.user; console.log(user.first_name, user.id); </script> </body> </html>
### React Setup
// hooks/useTelegram.js export function useTelegram() { const tg = window.Telegram?.WebApp;
return { tg, user: tg?.initDataUnsafe?.user, queryId: tg?.initDataUnsafe?.query_id, expand: () => tg?.expand(), close: () => tg?.close(), ready: () => tg?.ready(), }; }
// App.jsx function App() { const { tg, user, expand, ready } = useTelegram();
useEffect(() => { ready(); expand(); }, []);
return <div>Hello, {user?.first_name}</div>; }
### Bot Integration
// Bot sends Mini App bot.command('app', (ctx) => { ctx.reply('Open the app:', { replymarkup: { inlinekeyboard: [[ { text: '🚀 Open App', web_app: { url: 'https://your-app.com'; } } ]] } }); });
TON Connect Integration
Wallet connection for TON blockchain
When to use: When building Web3 Mini Apps
## TON Connect Integration
### Setup
npm install @tonconnect/ui-react
### React Integration
import { TonConnectUIProvider, TonConnectButton } from '@tonconnect/ui-react';
// Wrap app function App() { return ( <TonConnectUIProvider manifestUrl="https://your-app.com/tonconnect-manifest.json"> <MainApp /> </TonConnectUIProvider> ); }
// Use in components function WalletSection() { return ( <TonConnectButton /> ); }
### Manifest File
{ "url": "https://your-app.com", "name": "Your Mini App", "iconUrl": "https://your-app.com/icon.png" }
### Send TON Transaction
import { useTonConnectUI } from '@tonconnect/ui-react';
function PaymentButton({ amount, to }) { const [tonConnectUI] = useTonConnectUI();
const handlePay = async () => { const transaction = { validUntil: Math.floor(Date.now() / 1000) + 60, messages: [{ address: to, amount: (amount * 1e9).toString(), // TON to nanoton }] };
await tonConnectUI.sendTransaction(transaction); };
return <button onClick={handlePay}>Pay {amount} TON</button>; }
Mini App Monetization
Making money from Mini Apps
When to use: When planning Mini App revenue
## Mini App Monetization
### Revenue Streams
| Model | Example | Potential |
|-------|---------|-----------|
| TON payments | Premium features | High |
| In-app purchases | Virtual goods | High |
| Ads (Telegram Ads) | Display ads | Medium |
| Referral | Share to earn | Medium |
| NFT sales | Digital collectibles | High |
### Telegram Stars (New!)
// In your bot bot.command('premium', (ctx) => { ctx.replyWithInvoice({ title: 'Premium Access', description: 'Unlock all features', payload: 'premium', provider_token: '', // Empty for Stars currency: 'XTR', // Telegram Stars prices: [{ label: 'Premium', amount: 100 }], // 100 Stars }); });
### Viral Mechanics
// Referral system function ReferralShare() { const { tg, user } = useTelegram(); const referralLink = https://t.me/yourbot?start=ref${user.id};
const share = () => { tg.openTelegramLink( https://t.me/share/url?url=${encodeURIComponent(referralLink)}&text=Check this out! ); };
return <button onClick={share}>Invite Friends (+10 coins)</button>; }
### Gamification for Retention
- Daily rewards
- Streak bonuses
- Leaderboards
- Achievement badges
- Referral bonuses
Anti-Patterns
❌ Ignoring Telegram Theme
Why bad: Feels foreign in Telegram. Bad user experience. Jarring transitions. Users don't trust it.
Instead: Use tg.themeParams. Match Telegram colors. Use native-feeling UI. Test in both light/dark.
❌ Desktop-First Mini App
Why bad: 95% of Telegram is mobile. Touch targets too small. Doesn't fit in Telegram UI. Scrolling issues.
Instead: Mobile-first always. Test on real phones. Touch-friendly buttons. Fit within Telegram frame.
❌ No Loading States
Why bad: Users think it's broken. Poor perceived performance. High exit rate. Confusion.
Instead: Show skeleton UI. Loading indicators. Progressive loading. Optimistic updates.
