javascript - React PropTypes 导入类。 Prop 类型无效

Question

我有几个在许多组件中使用的大型对象，因此我为每个大型对象创建了一个 proptypes 文件，如下所示:

PropTypes/PropLargeObject.js 

其中包含 从“prop-types”导入 PropTypes；

const PropLargeObject =
    PropTypes.shape({
        id: PropTypes.number.isRequired, 
        name: PropTypes.string.isRequired,
        items: PropTypes.ArrayOf(PropTypes.Shape({
            itemId: PropTypes.number.isRequired,
            itemName: PropTypes.string.isRequired 
        }))
    });

export default PropLargeObject;

我在组件中使用该对象，如下所示:

import {PropLargeObject} from "./PropTypes/PropLargeObject";

Component.propTypes = {
    LargeObject: {PropLargeObject}
}

它向我发出警告 Prop 类型“PropLargeObject”无效，它必须是一个函数，通常来自 React.PropTypes。我在这里做错了什么？

Answer 1

删除不必要的花括号:

import PropLargeObject from "./PropTypes/PropLargeObject"; // PropLargeObject is the default export

Component.propTypes = {
    LargeObject: PropLargeObject // PropLargeObject is a PropTypes.shape function. Don't wrap with an object
}

您甚至可以将其短路一点:

import LargeObject from "./PropTypes/PropLargeObject"; // you can assign whatever name you want to default imports

Component.propTypes = {
    LargeObject
}
