Engineering & Coding Standards

1. TypeScript & Type Safety​

  • Enable strict mode (strict: true) in sconfig.json.
  • Avoid using ny; prefer explicit interfaces, unions, or unknown with type guards.
  • Share core types across frontend and backend when applicable.

2. Backend (Moleculer.js & Node.js)​

  • Service Isolation: Keep Moleculer service actions idempotent and lightweight.
  • Error Handling: Throw standardized MoleculerClientError or custom application errors with actionable error codes.
  • Database Transactions: Wrap multi-table operations in Prisma $transaction blocks.

3. Frontend (React & Redux Toolkit)​

  • Use functional components with typed props.
  • Group state management by domain module using Redux Toolkit slices and Sagas.
  • Avoid prop drilling; use dedicated component selectors.
