Request Swagger 용

export class PagingDTO {
  @Property({ apiProperty: { type: 'number', minimum: 1, default: 1 } })
  page?: number;

  @Property({ apiProperty: { type: 'number', minimum: 20, default: 20 } })
  limit?: number;

  constructor(page: number, limit: number) {
    this.page = page;
    this.limit = limit;
  }

  public getSkipTake(): SkipTake {
    const take = Number(this.limit) || 20;
    const skip = (Number(this.page) - 1) * take;

    return { skip, take };
  }
}

Response 데이터 전처리 용

export class PaginationDTO<T extends object> {
  @Property({ apiProperty: { isArray: true } })
  data: T[];

  @Property({ apiProperty: { type: PagingMetaDTO } })
  paging: PagingMetaDTO;

  constructor(data: T[], { paging, count }: PagingMetaDTOInterface) {
    this.data = data;
    this.paging = new PagingMetaDTO({ paging, count });
  }
}

미들웨어 적용

app.use(PaginationMiddleware);

Paging Params Decorator

async function example(@Paging() paging: PagingDTO) {}
