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. Supports both emotion and styled-components.

Compatibility Chart

We are currently testing against the following versions:

| stailwc | NextJS | Emotion | Styled Components | | ------- | ------ | ------- | ----------------- | | latest | 13.0.1 | 11.10.5 | 5.3.6 |

Feature Chart

| Feature | Emotion | Styled Components | | ------------------------------- | -------------- | ----------------- | | tw jsx attribute | ✅ | ✅ | | tw template tag | ✅ | ✅ | | tw component syntax | ✅¹ | ✅ | | tw component extension syntax | ✅¹ | ✅ | | Global styles | ✅² | ⛔³ | | plugin parameter suggestions | ✅ | ✅ |

1. Currently emotion requires a dummy import at the top of the file due to a swc bug. This will be fixed in the future.
2. Due to the same issue, a dummy import is required at the top of the for emotion. This will be fixed in the future.
3. Due to the same issue, styled-components global css does not work.

Getting started

```bash

npm add -D stailwc yarn add -D 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:

next.config.js

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

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

module.exports = nextConfig; ```

Optionally, you can also include the tailwind normalizer + forms plugin by including the <TailwindStyle /> component. This is currently not possible with styled-components, but will be once issue #22 is resolved.

_document.tsx

```tsx import { TailwindStyle } from "stailwc";

// currently needed due to a swc bug // === import { css, Global } from "@emotion/react"; css; Global; // ===

export default function App({ Component, pageProps }) { return ( <> ); } ```

Now get hacking!

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.

```tsx import { useState } from "react";

export const ColorButton = () => { const [clicked, setClicked] = useState(0); return ( border-green : twborder-blue} onClick={() => setClicked(clicked + 1)} > Clicked {clicked} times ); }; ```

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.

```tsx // currently needed with emotion due to a swc bug // === import _styled from "@emotion/styled"; _styled; // ===

export const StyledButton = tw.buttonp-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.
