Step-by-step guide

Telegram Mini Apps (TMA) are web applications that run inside the Telegram app. They are built using web technologies, including HTML, CSS, and JavaScript. TMAs can be used to create apps and games.

Create your Mini App​

  1. To connect your Mini App to Telegram, add the SDK script telegram-web-app.js using this code:
<script src="https://telegram.org/js/telegram-web-app.js"></script>
tip

It's best to disable caching using HTTP response headers. To ensure caching is disabled, configure these headers in your server responses:

Cache-Control: no-store, must-revalidate
Pragma: no-cache
Expires: 0

  1. Once the script is loaded, the window.Telegram.WebApp object becomes available. Learn more about creating a Mini App using telegram-web-app.js.

  2. You can also use the @twa-dev/sdk npm package:

npm install @twa-dev/sdk

See the Modern TMA example for @twa-dev/sdk in this guide.

  1. Once your Mini App is deployed, continue with Setting up a bot for the Mini App.
