反作用中重用顺风组件的简单方法

Question

我是一个使用顺风css在反应。我想知道如何简单地重用顺风按钮样式，以及在哪里保存该文件？

   export default function App() {
      return (
        <div className="App">
            <button
              // className='btn-indigo'
              className="py-2 px-4 bg-green-500 text-white font-semibold rounded-lg shadow-md hover:bg-green-700 focus:outline-none focus:ring-2 focus:ring-green-400 focus:ring-opacity-75"
            >
              Button1
            </button>

            <button
              // className='btn-indigo'
              className="py-2 px-4 bg-green-500 text-white font-semibold rounded-lg shadow-md hover:bg-green-700 focus:outline-none focus:ring-2 focus:ring-green-400 focus:ring-opacity-75"
            >
              Button2
            </button>
      }

Answer 1

您可以使用@apply指令：

// do this in your CSS file

.my-btn {
  @apply py-2 px-4 bg-green-500 text-white font-semibold rounded-lg shadow-md hover:bg-green-700 focus:outline-none focus:ring-2 focus:ring-green-400 focus:ring-opacity-75;
}

然后在你的JSX代码中：

<button className="my-btn">Foo</button>

此外，您还可以创建一个简单的组件文件：

// src/components/MyButton.jsx

const MyButton = ({ children }) => <button className="py-2 px-4 bg-green-500 text-white font-semibold rounded-lg shadow-md hover:bg-green-700 focus:outline-none focus:ring-2 focus:ring-green-400 focus:ring-opacity-75">{children}</button>

export default MyButton

在应用程序文件中：

import MyButton from './components/MyButton'

// ...

<MyButton>foo</MyButton>
<MyButton>bar</MyButton>

如果您也想传递其他道具，则需要修改MyButton。尽管如此，我还是建议使用像造型-部件或情感这样的CSS库。还有一些特定于尾风的替代方案可能会让你感兴趣：twin.macro、特风、X风。

最简单的方法--只需将类存储在字符串中。

const myBtn = "py-2 px-4 bg-green-500 text-white font-semibold rounded-lg shadow-md hover:bg-green-700 focus:outline-none focus:ring-2 focus:ring-green-400 focus:ring-opacity-75"

// ...

<button className={`${myBtn} some-other-class-specific-to-foo`}>Foo</button>
<button className={myBtn}>Bar</button>

您还可以使用像类名和clsx这样的库来组合字符串。

我正在使用TypeScript共享我的一个实现。

您可以了解如何使用顺风重用任何组件。实现、命名和注释通常都是固执己见的。

// src/components/atoms/Button.tsx
import {DefaultComponent} from '$types/common';
import {NoopFn, classNames} from '@utils';
import {ReactElement} from 'react';

type ButtonUse = `primary` | `secondary` | `destructive`;
type ButtonSize = `xs` | `sm` | `md`;
type ButtonType = `button` | `submit`;

type ButtonProps = DefaultComponent & {
  size?: ButtonSize;
  type?: ButtonType;
  use?: ButtonUse;
};

const BUTTON_SIZE: {[key in ButtonSize]: string} = {
  md: `text-base px-4 py-2`,
  sm: `text-sm px-3 py-2 leading-4`,
  xs: `text-xs px-2.5 py-1.5`,
};

const BUTTON_COLOR: {[key in ButtonUse]: string} = {
  destructive: `text-white bg-red-600 hover:bg-red-700`,
  primary: `text-white bg-indigo-600 hover:bg-indigo-700`,
  secondary: ``,
};

export const Button = (props: ButtonProps): ReactElement => {
  const {
    className = ``,
    children,
    use = `primary`,
    size = `xs`,
    type = `button`,
    onClick = NoopFn,
  } = props;
  return (
    <button
      {...{onClick, type}}
      className={classNames(
        `inline-flex items-center border border-transparent font-medium rounded shadow-sm focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-indigo-500 justify-center`,
        BUTTON_SIZE[size],
        BUTTON_COLOR[use],
        className,
      )}>
      {children}
    </button>
  );
};
