Frontend (codify-frontend/.env.local):

DATABASE_URL="mongodb://localhost:27017/codify"
NEXTAUTH_SECRET="your-secret-key-here"
NEXTAUTH_URL="http://localhost:3000"
EXECUTION_SERVER_URL="http://localhost:8080"
NEXT_PUBLIC_WS_SERVER_URL="ws://localhost:8080"

Execution Server (codify-execution-server/.env):

PORT=8080
HOST=0.0.0.0
FRONTEND_URL=http://localhost:3000
MAX_CONCURRENT_EXECUTIONS=10
EXECUTION_TIMEOUT_MAX=30
CODE_SIZE_LIMIT=51200
RATE_LIMIT_POINTS=50
RATE_LIMIT_DURATION=60

Running the Application

Start both services in separate terminals:

Terminal 1 - Execution Server:

cd codify-execution-server
npm run dev
