  // ...

  /** Basic usage */
  @Cacheable()
  public getCategories() {
    return this.httpService.get('my-url');
  }

  /** Specifing a TTL: 1 second */
  @Cacheable({ ttl: 1000 })
  public getCategories() {
    return this.httpService.get('my-url');
  }

  /** Custom key */
  @Cacheable({ key: 'categories-list' })
  public getCategories() {
    return this.httpService.get('my-url');
  }

  /** Custom function key */
  @Cacheable({ key: (args: any[]) => {
    return 'categories-page-' + args[0]; // args[0] is the first method argument. Here it is `page`.
  } })
  public getCategories(page: number, other: string) {
    return this.httpService.get('my-url', { page, other });
  }
