React Styled-组件3按钮尺寸

Question

什么是最好的方式有3种风格类型的基础上的道具？

 const Button = styled.button`
   background: teal;
   border-radius: 8px;
   color: white;
   height: ${props => props.small ? 40 : 60}px;
   width: ${props => props.small ? 60 : 120}px;
`;

class Application extends React.Component {
  render() {
    return (
      <div>
        <Button small>Click Me</Button>
        <Button>Click Me</Button>
        <Button large>Click Me</Button>
      </div>
    )
  }
}

下面是我使用的一个选项的缩略示例。

/* import separate css file from styles.js */
import * as Styles from './styles';

/* concat styles based on props */
const ButtonBase = styled.button`
  ${Styles.buttonbase};
  ${props => Styles[props.size]};
  ${props => Styles[props.variant]};
`;

const Button = ({ size, variant, ...rest }) => (
  <ButtonBase
    size={size}
    variant={variant}
    {...rest}
    ...

在样式文件中（为了简洁，去掉了css）

import { css } from 'styled-components';

/* styles common to all buttons */
export const buttonbase = css`...`;

/* theme variants */
export const primary = css`...`;
export const secondary = css`...`;
export const tertiary = css`...`;

/* size variants */
export const small = css`...`;
export const medium = css`...`;
export const large = css`...`;
