# OpenAPI & Documentation

## **Priority: P2 (MAINTENANCE)**

Automated API documentation and OpenAPI standards.

## Workflow

1. **Enable the Swagger plugin** in `nest-cli.json` to auto-generate `@ApiProperty` from DTOs.
2. **Annotate controllers** with `@ApiTags`, `@ApiResponse`, and auth decorators.
3. **Create generic wrappers** for paginated and polymorphic responses.
4. **Generate separate docs** for public vs internal audiences.

## Setup

See [implementation examples](references/example.md) for `nest-cli.json` plugin config and Swagger bootstrap.

## Response Documentation

- **Strictness**: Every controller method must have `@ApiResponse({ status: 200, type: UserDto })`.
- **Generic Wrappers**: Define `ApiPaginatedResponse<T>` decorators using `ApiExtraModels` + `getSchemaPath()` to handle generics properly.

## Advanced Patterns

- **Polymorphism**: Use `@ApiExtraModels` and `getSchemaPath` for `oneOf`/`anyOf` union types.
- **File Uploads**: Use `@ApiConsumes('multipart/form-data')` with explicit `@ApiBody` schema.
- **Authentication**: Use `@ApiBearerAuth()` or `@ApiSecurity('api-key')` matching `DocumentBuilder` config.
- **Enums**: Force named enums: `@ApiProperty({ enum: MyEnum, enumName: 'MyEnum' })`.

## Operation Grouping

- **Tags**: Mandatory `@ApiTags('domains')` on every Controller.
- **Multiple Docs**: Generate separate docs for different audiences (Public vs Internal).

See [implementation examples](references/example.md)

## Anti-Patterns

- **No missing @ApiResponse**: Every controller method must declare its response type and status code.
- **No /docs in production**: Disable Swagger in production to prevent API schema exposure.
- **No manual @ApiProperty everywhere**: Use the Nest CLI Swagger plugin to auto-generate from DTOs.
