Answer
Use modular structure, proper state management, facades, smart/dumb components, DRY architecture, consistent naming, and unit-tested services/components for long-term maintainability.
Quick Answer
Angular maintainability: apply consistent architecture (Core/Shared/Feature modules or standalone components), use smart/dumb component pattern, keep components small (split when >300 lines), lazy load all feature routes, use TypeScript strictly (strict mode), write tests for services and critical components, document with JSDoc, and enforce standards via ESLint + Angular-specific lint rules.
