Building Blocks for Telegram Web Apps
This repo provides an npm package for building Web App for your Telegram bot. It simply re-exports the API provided by Telegram's JS module which you must still script-tag include.
The advantage of this package is that is bundles up TypeScript types, which may
make it easier to set up the project. In addition, it will allow you to properly
scope access to window.Telegram, rather than relying on the global scope.
Installation
You need to include the CDN script from Telegram. Add this to your main HTML
file in the <head> tag:
<script src="https://telegram.org/js/telegram-web-app.js"></script>You can then use this package in your application by running
npm install @grammyjs/web-appIn turn, you can import from it:
import { WebApp } from "@grammyjs/web-app";
console.log(WebApp.initData);
// same as
console.log(window.Telegram.WebApp.initData);Once your application is ready to be displayed, you should call ready().
WebApp.ready();Consult
the offical Telegram docs for Web Apps
to see what else is available through WebApp.
