1 - Create an entity

export interface ICar {
  uuid?: number | string | undefined;
  name: string;
  releaseYear: number;
}

export class CarEntity implements ICar {
  @Id()
  uuid = undefined;
  name: string = "";
  releaseYear: string = "";

  constructor(obj: IDevice) {
    Object.assign(this, obj);
  }

  get getCarNameAndReleaseYear() {
    return `${this.name} - ${this.releaseYear} `;
  }
}

• 2 create an instance of Repository

let repo = new Repository<CarEntity>("endoint", CarEntity);

• 3 now you have access to the following methods

  save(postObj: T): Observable<T>;
  update(updateObj?: T): Observable<T>;
  delete(id: string | number): Observable<T>;
  getByParams(params: { key: string; value: string | number }[]): Observable<T>;
  getAll(): Observable<T[]>;
  paginatedQuery(
    paginatedQuery: PaginatedQuery | any,
    subUrl?: string
  ): Observable<T[]>;
  get(id: number | string): Observable<T>;

• Example :

const car = new CarEntity({
  uuid: "9876-udikz-sdae-7897",
  name: "Ferrari",
  releaseYear: 2016,
});

repo.save(car).subscribe((car: CarEntity) => {});

const updateCar = new CarEntity({
  uuid: "9876-udikz-sdae-7897",
  name: "Ferrari",
  releaseYear: 2018, // updated value
});

repo.update(car).subscribe((car: CarEntity) => {});
