Telegram Bot for Cloudflare Workers

A Telegram bot framework running entirely on Cloudflare Workers, with Workers AI wired up so bots can answer using Gemini and Gemma.

The problem

Run a useful Telegram bot without a persistent server while keeping webhook handling, shared types and the companion web application deployable together.

Architecture

grammY handles Telegram updates inside a Cloudflare Worker.
A Svelte 5 web application provides the browser-facing interface.
Shared packages keep types and helpers consistent across both deployments.

Highlights

Separate development and production Worker bindings
Webhook authentication and automated deployment
Workers AI and web-search integrations for bot responses
