Optimize module imports by marking `DatabaseModule` and `CryptoModule` as global. Remove explicit imports from other modules to reduce duplication and improve maintainability. Update environment variable limits for image and GIF sizes in production.
Add `@MaxLength` validations to limit string field lengths in multiple DTOs, ensuring consistent data validation and integrity. Integrate `CreateApiKeyDto` in the API keys controller for improved type safety.
Refactor multiple modules to improve dependency management by adding missing imports (e.g., `AuthModule`, `CryptoModule`) and ensuring essential services and repositories are exported. Update Dockerfile for better build and runtime efficiency, improve CORS handling, and enhance validation with updates to DTOs. Include package.json refinements for dependency organization.
Introduce repository pattern across multiple services, including `favorites`, `tags`, `sessions`, `reports`, `auth`, and more. Decouple crypto functionalities into modular services like `HashingService`, `JwtService`, and `EncryptionService`. Improve testability and maintainability by simplifying dependencies and consolidating utility logic.
Integrate `Logger` for consistent logging in services like `reports`, `categories`, `users`, `contents`, and more. Introduce caching capabilities with `CacheInterceptor` and manual cache clearing logic for categories, users, and contents. Add request throttling to critical auth endpoints for enhanced rate limiting.
Added unit tests for the `api-keys`, `auth`, `categories`, `contents`, `favorites`, `media`, and `purge` services to improve test coverage and ensure core functionality integrity.
Added a dedicated ApiKeysModule to manage API keys. Includes functionality to create, list, revoke, and validate keys, leveraging cryptographic hashing and database support. Integrated with authentication guards for security.
