Class NGXS 中状态的基于对象实例

Question

It is not recommended to add Class based object instances to your state because this can lead to undefined behavior in the future.

例如

//== This is NOT recommended:
ctx.setState((state: Todo[]) => state.concat(new Todo(action.title)));

//== This is recommended
state.concat({ title: action.title, isCompleted: false })

为什么不建议使用 new 创建 class 实例？

Answer 1

因为那些创建的对象有多个属性，比如函数、构造函数，也许还有私有属性等等 ... 您也不想保存这些属性！

你的待办事项中应该有导出功能-class:

interface TodoModel {
  /* your properties you want to take care of! */
}

class Todo implements TodoModel {
  export(): TodoModel {
  }

  import(model: TodoModel) {
  }
}
