属性“儿童"的类型缺失 [英] Property 'children' is missing in type

问题描述

我正在尝试使用 babel-loader 和 ts-loader.

I am trying to setup Storybook with Typescript using babel-loader and ts-loader.

除了在 React 组件中使用 children 之外，一切正常:

Everything works fine except using children in a React component:

[tsl] ERROR in .../stories/index.stories.tsx(8,56)
      TS2769: No overload matches this call.
      Property 'children' is missing in type '{ title: string; }' but required in type 'Props'.

这是 .storybook/main.js 文件:

module.exports = {
  addons: [
    "@storybook/addon-knobs",
  ],
  stories: ["../packages/**/*.stories.tsx"],
  webpackFinal: async config => {
    config.module.rules.push({
      test: /\.(ts|tsx)$/,
      exclude: /node_modules/,
      use: [
        {
          loader: require.resolve('ts-loader')
        },
        {
          loader: require.resolve('babel-loader'),
          options: {
            presets: [
              "@babel/preset-env",
              "@babel/preset-react"
            ]
          }
        }
      ],
    });

    config.resolve.extensions.push('.ts', '.tsx');

    return config;
  }
};

这是 index.stories.tsx 文件:

import React from "react";

import Collapsible from "../src";

export default {
  title: "Collapsible"
};

const content = <span>Content</span>;

export const simpleCollapsible = () => (
  <Collapsible title="Collapsible">{content}</Collapsible>
);

这是可折叠的实现:

import React, { ReactNode, useState } from "react";
import styled, { ThemeProvider } from "styled-components";
import {
  BorderProps,
  ColorProps,
  FlexboxProps,
  LayoutProps,
  SpaceProps,
  TypographyProps
} from "styled-system";
import Theme from "@atw/theme";

import { KeyboardArrowDown } from "@styled-icons/material";

import Box from '~/box';
import Button from '~/button';

interface Props
  extends BorderProps,
    ColorProps,
    FlexboxProps,
    LayoutProps,
    SpaceProps,
    TypographyProps {
  children: ReactNode;
  title: string;
}

const Collapsible = ({ children, title, ...rest }: Props) => {
  const [isCollapsed, setIsCollapsed] = useState(false);

  const handleCollapse = () => {
    setIsCollapsed(!isCollapsed);
  };

  return (
    <ThemeProvider theme={Theme}>
      <Button
        border="none"
        padding={0}
        marginBottom={2}
        width={1}
        textAlign="start"
        onClick={handleCollapse}
        {...rest}
      >
        <IconBox isCollapsed={isCollapsed}>
          <KeyboardArrowDown size="24px" />
        </IconBox>
        {title}
      </Button>
      {!isCollapsed && (
        <Box display="flex" flexDirection="column">
          {children}
        </Box>
      )}
    </ThemeProvider>
  );
};

export default Collapsible;

是不是我做错了什么?

推荐答案

一种可能的解决方案是利用功能组件中的默认子级机制，React.FC，它允许您在不显式包含的情况下挂载子级它们作为您的类型定义中的道具.对于您的情况，可以通过应用以下更改来实现:

One possible solution is to leverage the default children mechanism in functional components, React.FC, which lets you mount children without explicitly include them as a prop in your type definition. For your case this is achievable by applying the following changes:

interface Props
  extends BorderProps,
    ColorProps,
    FlexboxProps,
    LayoutProps,
    SpaceProps,
    TypographyProps {
  title: string;
}

const Collapsible: React.FC<Props> = ({ children, title, ...rest }) => {
  ...
};

为此工作沙箱
