TypeScript和React-子类型? [英] TypeScript and React - children type?

问题描述

我有一个非常简单的功能组件，如下所示:

I have a very simple functional component as follows:

import * as React from 'react';

export interface AuxProps  { 
    children: React.ReactNode
 }


const aux = (props: AuxProps) => props.children;

export default aux;

另一个组件:

import * as React from "react";

export interface LayoutProps  { 
   children: React.ReactNode
}

const layout = (props: LayoutProps) => (
    <Aux>
        <div>Toolbar, SideDrawer, Backdrop</div>
        <main>
            {props.children}
        </main>
    <Aux/>
);

export default layout;

我不断遇到以下错误:

[ts] JSX元素类型'ReactNode'不是JSX元素的构造函数. 类型'undefined'不能分配给'ElementClass'类型. [2605]

[ts] JSX element type 'ReactNode' is not a constructor function for JSX elements. Type 'undefined' is not assignable to type 'ElementClass'. [2605]

如何正确输入?

推荐答案

只需children: React.ReactNode
