成员应在所有私有实例之前声明

Question

private userSubject$: BehaviorSubject<UserModel> = new BehaviorSubject<UserModel>(null);
userChanged$: Observable<UserModel> = this.userSubject$.asObservable();

它说：

Member userChanged$ should be declared before all private instance field definitions.eslint@typescript-eslint/member-ordering

我喜欢这条规则。但是如何在不禁用此规则的情况下使用上述代码？

如果我要更改订单，那么它会显示：

Property 'userSubject$' is used before its initialization.

Answer 1

您可以将初始化移动到构造函数中：

userChanged$: Observable<UserModel>;

private userSubject$: BehaviorSubject<UserModel>;

constructor() {
    this.userSubject$ = new BehaviorSubject<UserModel>(null);
    this.userChanged$ = this.userSubject$.asObservable();
}

成员应在所有私有实例之前声明

Member should be declared before all private instance
