Use Twin with Next + Styled Components

🔥 View the Next + Styled Components + Tailwind Twin starter for usage examples

Getting started

1. Install the dependencies

After creating your next app:

npm install --save twin.macro styled-components

Yarn instructions

yarn add twin.macro styled-components

2. Enable babel macros and configure styled-components

// In .babelrc
{
  "presets": [
    "next/babel"
  ],
  "plugins": [
    "babel-plugin-macros",
    [
      "styled-components",
      {
        "ssr": true
      }
    ]
  ]
}

3. Add the global styles

Projects using Twin also use the Tailwind preflight base styles to smooth over cross-browser inconsistencies.

Twin adds the preflight base styles with the GlobalStyles import which you can add in pages/_app.js:

// page/_app.js
import React from 'react'
import { GlobalStyles } from 'twin.macro'

const App = ({ Component, pageProps }) => (
  <>
    <GlobalStyles />
    <Component {...pageProps} />
  </>
)

export default App

GlobalStyles also includes some @keyframes so the animate-xxx classes have animations. But if you’re not using the animate classes then you can avoid adding the extra keyframes.

4. Add the recommended config

Twin’s recommended config can be added in a couple of different places.

a) In your package.json:

// package.json
"babelMacros": {
    "twin": {
      "config": "tailwind.config.js",
      "preset": "styled-components",
      "debugProp": true,
      "debugPlugins": false,
      "debug": false,
    }
},

b) Or in a new file named babel-plugin-macros.config.js placed in your project root:

// babel-plugin-macros.config.js
module.exports = {
  twin: {
    config: 'tailwind.config.js',
    preset: 'styled-components',
    debugProp: true,
    debugPlugins: false,
    debug: false,
  },
}

5. Complete the TypeScript support (optional)

Twin comes with types for every import except the css and styled imports.

6. Add the server stylesheet (optional)

To avoid the ugly Flash Of Unstyled Content (FOUC), add a server stylesheet in pages/_document.js that gets read by Next.js:

// pages/_document.js
import Document from 'next/document'
import { ServerStyleSheet } from 'styled-components'

export default class MyDocument extends Document {
  static async getInitialProps(ctx) {
    const sheet = new ServerStyleSheet()
    const originalRenderPage = ctx.renderPage
    try {
      ctx.renderPage = () =>
        originalRenderPage({
          enhanceApp: App => props => sheet.collectStyles(<App {...props} />),
        })
      const initialProps = await Document.getInitialProps(ctx)

      return {
        ...initialProps,
        styles: (
          <>
            {initialProps.styles}
            {sheet.getStyleElement()}
          </>
        ),
      }
    } finally {
      sheet.seal()
    }
  }
}

Note: Adding styles within this file won’t work like you would expect, take a look at this issue for a work around.

Options

Name	Type	Default	Description
config	string	"tailwind.config.js"	The path to your Tailwind config
preset	string	"emotion"	The css-in-js library behind the scenes - also supports 'styled-components' and 'goober'
hasSuggestions	boolean	true	Display class suggestions when a class can't be found
debugPlugins	boolean	false	Display generated class information in your terminal from your plugins
debugProp	boolean	false	Add a prop to your elements in development so you can see the original tailwind classes, eg: <div data-tw="bg-black" />
debug	boolean	false	Display information in your terminal about the Tailwind class conversions

If twin’s default styled and css imports need to be adjusted, you can do so with the following config:

{
  styled: { import: "default", from: "styled-components" },
  css: { import: "css", from: "styled-components/macro" }
}

Note: Make sure you remove the preset option as that value disables the styled + css options.
