How to define type in a array of context in react

Question

I have a context:

export const templateContext = createContext({
  isButtonDisable: true,
  setIsButtonDisable: (p: boolean) => {},
  isSubmitReady: <boolean>false,
  setIsSubmitReady: () => {},
  buttonShow: false,
  handleButtonShow: (val: boolean) => {},
  steps:  [] ,
  handleSteps: (val: never) => {},
});

I am not understanding How can I define the type of array in this context. especially the steps array. That array also contains object

Answer 1

您需要首先为您的对象添加类型，例如：

type MyContext = {
  isButtonDisable: boolean;
  setIsButtonDisable: (p: boolean) => {};
  // and so on //
  steps: String[];
};

如果数组很复杂，您也应该为其创建一个单独的类型。例如，您的数组包含一个Step对象数组：

type Step = {
  id: string;
  value: number;
};

所以现在你可以修改你的MyContext：

type MyContext = {
  isButtonDisable: boolean;
  setIsButtonDisable: (p: boolean) => {};
  // and so on //
  steps: Step[];
};
