Global Headers for all Controllers (nestJs swagger)

Question

Is there a way to globally add required headers to all endpoints / controllers in NestJS?

There is a controller bound decorator @ApiHeader. Is there a way to apply this to all endpoints?

Answer 1

Shortest way I have found is to do the following:

export function Headers() {
  return applyDecorators(
    ApiHeader({
      name: 'header1',
      description: "description"
    }),
    ApiHeader({
      name: 'header2',
      description: "description"
    }),
    ApiHeader({
      name: 'header3',
      description: "description"
    })
  );
}

@Headers()
@Controller('some-controller')
export class ContactsController {}
