MobX: pattern for updating data when other data changes?

example.js

class Store {
  constructor() {
    reaction(
      () => [this.filter, this.limit, this.order],
      () => this.getItems()
    );
    this.getItems();
  }
  
  @observable filter = '';
  @observable order = '';
  @observable limit = '';

  @observable items = [];

  @action async getItems() {
    const items = await api.getItems(this.filter, this.order, this.limit);
    this.items = items;
  }
}
