Telegram Casino Mini App (Demo)

This repository contains a small Telegram Mini App (web app) — frontend and a simple backend — for demo / testing only.
It uses a virtual currency (TestCredits). Do not use for real money gambling.

What's included

• frontend/ — static Web App (HTML, CSS, JS) that works inside Telegram's Web App container.
• backend/ — simple Node/Express server storing per-user balances in db.json.

Quick start (local)

Frontend (static)

Open frontend/index.html in a browser for local testing. For Telegram integration, you must serve it over HTTPS and register URL with BotFather.

Backend (Node)

cd backend
npm install
node server.js

By default the backend listens on port 4000.

Deploy quickly

Frontend (fast)

• Use Vercel or Netlify: create a new project, point the repo or upload the frontend folder, and deploy.
• Or serve the frontend folder from any static host (must be HTTPS).

Backend (fast)

• Use Render (free tier) or Railway:
  • Push backend to GitHub.
  • Create a new Web Service on Render, connect the repo, set npm start as the start command.

Registering Mini App with Telegram

1. Create a bot with @BotFather:
   • /newbot to create a bot; BotFather will return a bot token.
2. Register your Web App / Mini App:
   • Use BotFather commands to create a main Mini App or set the domain. You can use /newapp and follow instructions, or /setdomain to link the domain for the web widget (see Telegram docs).
   • Official docs: https://core.telegram.org/bots/webapps and https://core.telegram.org/widgets/login

Using inside Telegram

• Once the Mini App is registered and the domain/URL set, users can open it from your bot's profile or a menu button.
• The Web App receives initData from Telegram (user info). For server-backed accounts, use that initData to identify users on your backend.

Notes & Safety

• This is a demo. No real-money payments integrated.
• Be careful when allowing "cheater" options; only for development/testing.
