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 performance and flexibility while performing considerably better than babel-based alternatives (about 11x faster in my experience, proper benchmarks coming soon!)

🚨 We currently only support NextJS 12.2.5

Getting started

> yarn add stailwc

Currently the setup process is a little bit convoluted, but it will be cleaned up in the future, once we determine the best way to package this. Place the following in your next.config.js:


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

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  experimental: {
    swcPlugins: [stailwc()],
  compiler: {
    emotion: true,

module.exports = nextConfig;

Optionally, you can also include the tailwind normalizer.


import { Html, Head, Main, NextScript } from "next/document";

export default function Document() {
  return (
          href="[email protected]/src/css/preflight.css"
        <Main />
        <NextScript />

Now get hacking!


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 (
      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


Next currently doesn’t support the SWC error handler meaning that errors are logged only to the command line, and not shown visually on the screen. This will be supported down the line (see here: vercel/next.js#39779).
