delcard_games

An online card game platform for playing with friends — fully client-side, no server required.

Players connect directly peer-to-peer via PeerJS. The host is the source of truth: they validate actions, update game state, and broadcast it to all players.

Stack

• SvelteKit + TypeScript
• Tailwind CSS v4
• PeerJS (WebRTC P2P)

Getting started

npm install
npm run dev

Type-check:

npm run check

Deploy (Netlify)

This project is configured with @sveltejs/adapter-netlify.

• Build command: npm run build
• Publish directory: build (defined in netlify.toml)

Adding a game

The engine is designed so each game is a self-contained GameDefinition object — no framework knowledge needed.

See docs/engine.md for the full guide.
