stailwc (speedy tailwind compiler)

This is an experimental SWC transpiler to bring compile time tailwind macros to SWC (and nextjs) a-la twin macro. The goal is to give the same great compile-time ergonomics and flexibility while performing considerably better than babel-based alternatives. Supports both emotion and styled-components for CSS-in-JS, and many build systems such as SWC, nextjs, Vite, etc.

Getting started

> npm add -D stailwc
> yarn add -D stailwc
> pnpm add -D stailwc

To get started with NextJS, place the following in your next.config.js. For other framworks / tools, please see the examples.

next.config.js

const stailwc = require("stailwc/install");

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  experimental: {
    swcPlugins: [
      stailwc({
        engine: "emotion", // or "styled-components"
      }),
    ],
  },
  compiler: {
    emotion: true,
    // or
    styledComponents: true,
  },
};

module.exports = nextConfig;

Optionally, you can also include the tailwind normalizer + forms plugin by including the <TailwindStyle /> component. Please see the relevant examples.

_document.tsx

import { TailwindStyle } from "stailwc";

export default function App({ Component, pageProps }) {
  return (
    <>
      <TailwindStyle />
      <Component {...pageProps} />
    </>
  );
}

Types

There is one step you need to take to get types working. You need to add stailwc.d.ts to the root of your source folder.

Usage

The `tw` tag

You can interact with stailwc in two ways. The first is through the tw JSW attribute, and the second is via the tw template tag.

import { useState } from "react";

export const ColorButton = () => {
  const [clicked, setClicked] = useState(0);
  return (
    <button
      tw="p-1 m-4 text-green bg-white hover:(bg-gray text-yellow md:text-red) border-3"
      css={clicked % 2 == 0 ? tw`border-green` : tw`border-blue`}
      onClick={() => setClicked(clicked + 1)}
    >
      Clicked {clicked} times
    </button>
  );
};

Component syntax

You can also create styled components using the tw template tag. This will automatically create the correct syntax for both emotion and styled-components.

export const StyledButton = tw.button`p-1 m-4 text-green bg-white hover:(bg-gray text-yellow md:text-red) border-3`;
export const ShadowButton = tw(StyledButton)`shadow-lg`;

Examples

There are examples available for both emotion and styled-components. You can run them by cloning the repo and running yarn followed by yarn dev in the example directory. You will need to stailwc first.
