Development

# Install dependencies
pnpm install

# Build all packages
pnpm build

# Watch mode (all packages in parallel)
pnpm dev

# Type checking
pnpm typecheck

# Run tests
pnpm test

Publishing

Each package publishes independently to forge.nasty.sh:

# From package directory
cd core && pnpm publish
cd client && pnpm publish
cd server && pnpm publish

Or use CI/CD workflow (recommended):

git push origin master  # Triggers publish.yml workflow
