我最近开始学习如何使用 Mobx 来管理我的应用程序的状态，最近我遇到了以下错误:

Object literal may only specify known properties, and "data" does not exist in type "AnnotatiosMap<this, never>".

每当我想将我的类的属性设为私有(private)时，就会发生这种情况。但是，如果它是 public 或 protected，则不会出现此问题。

这是我的一小段代码:

import { makeObservable, observable } from "mobx";

class Base {
  private data: string[];

  constructor() {
    this.data = [];

    makeObservable(this, {
      data: observable,
    });
  }

  public getData = (): string[] => {
    return this.data;
  };

}

export default new Base();

我应该怎么做才能将我的属性(property)设为私有(private)但仍受到监视？

祝你有美好的一天!

最佳答案

From the docs :

By default TypeScript will not allow you to annotate private fields. This can be overcome by explicitly passing the relevant private fields as generic argument, like this: makeObservable<MyStore, "privateField" | "privateField2">(this, { privateField: observable, privateField2: observable })
