fullstack-conventions

You can enforce consistent API response shapes by applying full-stack coding conventions that mandate a standard structure like `{ data, error, meta }` across frontend and backend boundaries. This prevents fragmented implementations and keeps services aligned.

The best way to standardize React component states is to enforce conventions requiring functional React components with typed props and explicit loading, error, and empty states. This ensures consistent user experiences across feature development and bugfixes.

You ensure deterministic test coverage by following existing project test utilities and patterns to cover both happy and error paths for each API endpoint. Additionally, test user-visible frontend behavior to maintain robust engineering practices.

To validate API boundaries and keep controllers thin, enforce conventions that require validating inputs at the API layer, returning proper HTTP status codes, and avoiding internal error leakage. This maintains clean service-layer logic.

Yes, this approach works for database migrations and API contract updates by ensuring all agents follow shared patterns for migrations and service-layer logic. It maintains consistency across frontend React and backend TypeScript services during feature development.

Full-stack implementations become fragmented when multiple agents build features without enforced team-wide coding conventions for TypeScript, API boundaries, and testing. Applying a shared convention standard ensures alignment on API contracts and response shapes.
