How to Build Telegram Mini Apps with the TWA SDK in 2026
The @twa-dev/sdkis the official TypeScript SDK for Telegram Web Apps. It exposes the full Telegram WebApp API — init data, theming, haptic feedback, viewport controls, and payment integration — in a typed, tree-shakeable package. Here's how we set it up on every project.
1. Install @twa-dev/sdk
Add the SDK to your React or Vite project. It works with Next.js, React, and vanilla TypeScript.
npm install @twa-dev/sdk # or yarn add @twa-dev/sdk
2. Initialize the WebApp in React
Call WebApp.ready() as early as possible — ideally in your app entry point — to signal Telegram that your mini app has loaded and hide the loading indicator.
import WebApp from '@twa-dev/sdk';
// In your root component or _app.tsx
useEffect(() => {
WebApp.ready();
WebApp.expand(); // Full-screen mode
}, []);3. Access Telegram User Data
The SDK exposes the authenticated Telegram user without any OAuth flow. Validate the init data on your backend using HMAC-SHA256 before trusting it.
import WebApp from '@twa-dev/sdk';
const user = WebApp.initDataUnsafe?.user;
// { id, first_name, last_name, username, photo_url }
// Always validate on backend:
// HMAC-SHA256(data_check_string, secret_key)
// where secret_key = HMAC-SHA256(bot_token, "WebAppData")4. TON Connect 2.0 Integration
For Web3 mini apps, combine @twa-dev/sdk with @tonconnect/ui-react to let users connect their TON wallet (Tonkeeper, MyTonWallet) directly inside Telegram.
import { TonConnectButton } from '@tonconnect/ui-react';
import { TonConnectUIProvider } from '@tonconnect/ui-react';
// Wrap your app
<TonConnectUIProvider manifestUrl="https://yourapp.com/tonconnect-manifest.json">
<App />
</TonConnectUIProvider>
// Then in any component
<TonConnectButton />5. Telegram Stars & Payment Integration
Telegram Mini Apps support native in-app purchases via Telegram Stars and Stripe/payment provider webhooks. Use the WebApp API to open the invoice and handle the payment result.
import WebApp from '@twa-dev/sdk';
// Open a payment invoice (URL generated by your backend via Bot API)
WebApp.openInvoice(invoiceUrl, (status) => {
if (status === 'paid') {
// unlock feature, mint token, etc.
}
});Common @twa-dev/sdk Issues & Fixes
- → "WebApp is not defined" — The SDK only works inside Telegram. Use
typeof window !== 'undefined'guards for SSR builds. - → Init data validation fails — Check that your bot token matches the one the mini app was launched from. Tokens are environment-specific.
- → @twa-dev/sdk deprecated warnings in 2025 — The SDK merged into the official
@telegram-apps/sdkpackage. For new projects use@telegram-apps/sdk-react. - → Blank screen on Android — Set viewport meta tag:
<meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover">
