How do I return only the required fields in NestJs?

I'm trying to get all the records from the table.

controller:

  @Get('types')
  async getTypes(): Promise<PageTypeRO[]> {
      return this.pageService.findTypes();
  };

service:

 async findTypes(): Promise<PageTypeRO[]> {
     return await this.pageTypePropsRepository.find();
 }

interface (RO):

export interface PageTypeRO {
    readonly id: number
}

I expect to get an array with objects in which only the "id" field, but teach all the fields from the table.

You have to set columns you want to get, To make it work for you, you should edit FindTypes function:

async findTypes(): Promise<PageTypeRO[]> {
    return await this.pageTypePropsRepository.find({ select: ["id"] });
}
