Introduction

Stylify is a library that uses CSS-like selectors to generate optimized utility-first CSS based on what you write.

• ✅ CSS-like selectors
• ✅ No framework to study
• ✅ Less time spent in docs
• ✅ Mangled & Extremely small CSS
• ✅ No CSS purge needed
• ✅ Components, Variables, Custom selectors
• ✅ It can generate multiple CSS bundles

Also we have a page about what problems Stylify CSS solves and why you should give it a try!

Next.js setup

The easiest way to Setup the Next.js is using CLI:

• Run yarn create next-app
• Select your project name

This way you will get the default Next.js application skeleton.

Stylify CSS integration

Install the @stylify/unplugin package using NPM or Yarn:

yarn add @stylify/unplugin
npm i @stylify/unplugin

Open the next.config.js and copy the following content into it:

const { stylifyWebpack } = require('@stylify/unplugin');

const stylifyPlugin = (dev) => stylifyWebpack({
	dev: dev,
	bundles: [{
		// Generate CSS from all js files
		files: ['./pages/**/*.js'],
		outputFile: './styles/stylify.css',
	}]
});

module.exports = {
	reactStrictMode: true,
	webpack: (config, { dev }) => {
		// Add Stylify CSS Webpack plugin
		config.plugins.push(stylifyPlugin(dev));
		return config;
	}
}

The last step, open the pages/_app.js and add the path to stylify.css:

// ...
import '../styles/stylify.css';

function MyApp({ Component, pageProps }) {
	return <Component {...pageProps} />
}

export default MyApp;

Styling the website

If you copy the code below into the pages/index.js and run yarn dev you will get a styled Hello World! text:

export default function Home() {
	return <div className="color:blue">Hello World!</div>;
}

Stylify watches any change in the js files and generates CSS into the styles/stylify.css. If you add a selector like font-size:24px the CSS will be automatically updated 🎉.

Go ahead and try Stylify CSS directly on Stackblitz.com 💡.

Components

Templates bloated with utility selectors are hard to read. Stylify allows you to define components directly in files, where they are used through content options (expects javascript object without brackets) or in the compiler config.

/*
stylify-components
	container: 'max-width:800px margin:0_auto'
/stylify-components
*/
export default function Home() {
	return (
		<div className="container">
			<div className="color:blue">Hello World!</div>
		</div>
	)
}

Variables

It’s a good practice to avoid hardcoded values in the selectors. Variables can be defined in the same way as components:

/*
stylify-variables
	blue: 'steelblue',
	containerWidth: '800px'
/stylify-variables

stylify-components
	container: 'max-width:$containerWidth margin:0_auto'
/stylify-components
*/
export default function Home() {
	return (
		<div className="container">
			<div className="color:$blue">Hello World!</div>
		</div>
	)
}

The production build

When we run the production build using yarn build + yarn start, the JSX markup will be mangled into this:

export default function Home() {
	return (
		<div className="a">
			<div className="b">Hello World!</div>
		</div>
	)
}

The CSS is shortened too:

:root {
	--blue: #4682b4;
	--containerWidth: 800px
}
.b {color: #4682b4}
.a,.c { max-width: 800px }
.a,.d { margin: 0 auto }

Configure anything you need

The examples above don’t include everything Stylify CSS can do:

• You can map nested files in the template
• Style custom selectors
• Define custom screens
• Add your macros like ml:20px for margin-left
