Telegram Bot & Mini App with Kotlin Multiplatform (KMP)

This is a simple Telegram Bot and Mini App project built using Kotlin Multiplatform (KMP). It demonstrates how to create a cross-platform application where the client-side Mini App runs in Telegram using WebAssembly (WASM) and the backend logic is handled by a Ktor server.

Features

• Cross-Platform: Built with Kotlin Multiplatform, allowing code sharing between the client (WASM) and server (JVM).
• Telegram Bot Integration: A simple Telegram bot that can interact with users.
• Telegram Mini App: A web-based application running within Telegram, built with Kotlin/WASM.
• Ktor Backend: Uses the Ktor framework for handling server-side logic and potentially API endpoints for the Mini App.

Tech Stack

• Kotlin Multiplatform (KMP): The foundation for building cross-platform applications.
• Kotlin: The primary programming language.
• Telegram Bot API: Used to interact with the Telegram Bot platform.
• WebAssembly (WASM): Enables the client-side Mini App to run in Telegram.
• Ktor: A powerful and lightweight asynchronous framework for creating the backend server.
• Gradle: The build automation system.

How to run

• Create a new telegram bot using Telegram Bot Father. give it a name and copy the token.
• Use ngrok to create an https domain for the web app locally.
