Project Structure

Top-level layout

• client/: frontend application
• server/: backend application
• shared/: shared TypeScript contracts, permissions, and utility types
• Dockerfile: production container build
• docker-entrypoint.sh: migration-aware startup script

Frontend rules

• Organize code by domain under src/modules.
• Keep app-shell concerns in src/app.
• Keep reusable UI primitives in src/components.
• Theme state and brand tokens belong in src/theme.
• PDF screen components must remain separate from API-rendered document templates.

Backend rules

• Organize domain modules under src/modules/<domain>.
• Keep HTTP routers thin; place business logic in services.
• Centralize Prisma access, auth middleware, and file storage utilities in src/lib.
• Store persistence-related constants under src/config.
• Serve the built frontend from the API layer in production.

Shared package rules

• Place cross-app DTOs, permission keys, enums, and document interfaces in shared/src.
• Keep shared code free of runtime framework dependencies.

Adding a new domain

1. Add backend routes, service, and repository/module files under server/src/modules/<domain>.
2. Add Prisma models and a migration if the module needs persistence.
3. Add permission keys in shared/src/auth.
4. Add frontend route/module under client/src/modules/<domain>.
5. Register navigation and route guards through the app shell without refactoring existing modules.
