React-样式的组件，道具和打字稿

Question

我研究了样式化的组件，并尝试了网站上的示例，但我也想使用打字稿。

我在这里有一个简单的例子

import React from 'react';
import './App.css';
import styled from 'styled-components';

interface IProps{
  primary: boolean
}

const App:React.FC<IProps> = ({primary}) => {
  return (
    <div className="App">
      <h1>Styled Components</h1>

      <Button>Normal</Button>
      <Button primary>Primary</Button>
    </div>
  );
}

const Button = styled.button`
  background: ${props => props.primary ? 'red' : 'white'};
  color: ${props => props.primary ? 'white' : 'red'};
  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border: 1px solid green;
  border-radius: 3px;
`

export default App;

但是我在主要道具上遇到了错误

我收到错误消息

Property 'primary' does not exist on type 'ThemedStyledProps<Pick<DetailedHTMLProps<ButtonHTMLAttributes<HTMLButtonElement>, HTMLButtonElement>, "form" | ... 264 more ... | "onTransitionEndCapture"> & { ...; }, any>'

我可以将带样式的组件与打字稿一起使用

Answer 1

将带样式的组件与打字稿一起使用：

const Button = styled.button<{ primary?: boolean }>`

完整代码：

import * as React from 'react';
import styled from 'styled-components';

interface IProps{
  primary?: boolean
}

const App:React.FC<IProps> = () => {
  return (
    <div className="App">
      <h1>Styled Components</h1>
      <Button>Normal</Button>
      <Button primary>Primary</Button>
    </div>
  );
}

const Button = styled.button<{ primary?: boolean }>`
  background: ${props => props.primary ? 'red' : 'white'};
  color: ${props => props.primary ? 'white' : 'red'};
  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border: 1px solid green;
  border-radius: 3px;
`

export default App;

Answer 2

我从我的项目中准备了一个示例

Wrapper.ts(styled-component)

import styled from 'styled-components';

interface Props {
    height: number;
}

export const Wrapper = styled.div<Props>`
    padding: 5%;
    height: ${(props) => props.height}%;
`;

index.tsx

import React, { FunctionComponent } from 'react';
import { Wrapper } from './Wrapper';

interface Props {
    className?: string;
    title: string;
    height: number;
}

export const MainBoardList: FunctionComponent<Props> = ({ className, title, height }) => (
    <Wrapper height={height} className={className}>
        {title}
    </Wrapper>
);

1. 您可以将接口/类型从“index.tsx”导入到“Wrapper.ts”以重复使用。

2. 否则你可以像这样指定类型

   export const Wrapper = styled.div<{height:number}>`
