• ✅ Docker + Docker Compose configuration to run both together

---

📦 Project Structure

./            → Haskell Scotty app (with Dockerfile)
/web-client        → Vite + React app (with Dockerfile)
docker-compose.yml → top-level orchestration

1️⃣ Clone the repository:

git clone https://github.com/claeusdev/l-lang
cd l-lang

2️⃣ Build and start everything:

docker compose up --build

✅ This will:

• Build the server from the Haskell Dockerfile.

• Build the client from the React Dockerfile.

• Expose:

  • Server → http://localhost:3000
  • Client (Vite dev server) → http://localhost:5173
