Documenting a Generic Resource Controller
This document describes the functionalities and structure of a general NestJS controller managing resources within an application.
Purpose:
- Acts as the main point of interaction between the API and the service layer for a specific resource.
- Handles incoming API requests related to CRUD operations (Create, Read, Update, Delete) and other resource-specific actions.
- Provides methods for fetching, filtering, searching, creating, updating, and deleting resource data.
Key Elements:
- Path: Defined using decorators like
@Get,@Post, etc., specifying the API endpoint URLs. - API Documentation: Uses decorators like
@ApiTags,@ApiQuery,@ApiBearerAuthand@ApiPropertyto generate Swagger documentation with authentication. - Service Injection: Injected with the service class responsible for business logic and data access.
- Methods:
- Each method corresponds to a specific API endpoint and performs data retrieval, creation, update, or deletion.
- Methods often use request, query, and body parameters to access data from the client.
- May implement pagination and search functionality depending on resource requirements.
Benefits:
- Promotes separation of concerns between controllers and services.
- Improves API clarity and maintainability with clear endpoint definitions and documentation.
- Simplifies service implementation by providing a defined interface for interaction.
Additional Notes:
- The specific resource name, methods, and functionalities will vary depending on your application's needs.
- Consider adding comments to explain the purpose of each method and its interaction with the service layer.
- This is a generic overview, and you might need to adjust it to reflect the specific structure and methods of your controller.
