Question

我正在尝试为具有工厂功能（称为“新”）的外部库编写TS定义。问题在于，在接口中添加一个名为“ new”的函数是指构造函数的类型。

有什么办法可以逃脱新关键字或使这种类型正常工作？

export interface Container {

  //This is what I want, except as a regular function, not the constructor
  new<T>(TConstructor: new () => T, locals?: object): T;

}

Answer 1

添加一对引号就足够了：

export interface Container {

  //This is what I want, except as a regular function, not the constructor
  'new'<T>(TConstructor: new () => T, locals?: object): T;

}

Answer 2

您只需引用方法标识符：

export interface Container {

  'new'<T>(TConstructor: new () => T, locals?: object): T;

}

declare let o: Container;
o.new(null!)
