The two most popular CSS-in-JS libraries, styled-components and Emotion, don’t support Preact out of the box. However there is an easy workaround.
Add these aliases to your webpack.config.js file:
module.exports = {
resolve: {
alias: {
react: 'preact/compat',
'react-dom/test-utils': 'preact/test-utils',
'react-dom': 'preact/compat',
},
},
};Adding these aliases allows you to use other libraries intended for React too!
And if you’re using Storybook, you’ll need to add the same alias to your .storybook/main.js file:
module.exports = {
stories: ['../app/javascript/**/story.tsx'],
webpackFinal: async config => {
config.resolve.alias = Object.assign({}, config.resolve.alias, {
react: "preact/compat",
'react-dom': 'preact/compat'
})
return config;
},
};After this you can install your preferred package:
npm i @emotion/styled
# OR
npm i styled-componentsAnd use either styled-components or Emotion without any problems:
import styled from '@emotion/styled';
// OR
import styled from 'styled-components';
export const Container = styled.div`
background-color: pink;
