Style your React.js website faster with Stylify CSS

Stylify + React.js + Vite.js. Style your React.js website faster with Stylify. Don't study selectors and syntax. Use pure CSS syntax and get generated CSS with advanced optimization for production.

For easier start, you can checkout the Stylify Stackblitz playground 🎮.

💎 Stylify Introduction

Stylify generates CSS dynamically based on what you write. The syntax is similar to css property:value. Defined utilities are combined with components selectors and in production minified to bare minimum like .color\:red,.button {color:red} to ._zx, ._ga{color:red}.

Stylify allows you to get very small bundles, generate additional lazyloaded CSS chunks and style the page by writting HTML and selectors 🤟.

🚀 React.js Setup

The easiest way to Setup the React.js is using cli:

Run yarn create vite app
Select react or react-ts
Then cd app

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

🔌 Stylify Integration

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

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

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

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { vitePlugin } from '@stylify/unplugin';

const stylifyPlugin = vitePlugin({
    transformIncludeFilter: (id) => {
        // Process only js, jsx, ts, tsx,
        return id.endsWith('js') || id.endsWith('ts') || id.endsWith('tsx') || id.endsWith('jsx');
    },
    bundles: [{
        // Create only one bundle for whole project => stylify.css
        outputFile: './src/stylify.css',
        files: ['./src/**/*.js', './src/**/*.ts', './src/**/*.jsx', './src/**/*.tsx'],
    }],
    extend: {
        bundler: {
            compiler: {
                selectorsAreas: [
                    // To find class attributes
                    '(?:^|\\s+)className="([^"]+)"',
                    '(?:^|\\s+)className=\'([^\']+)\'',
                    '(?:^|\\s+)className=\\{`((?:.|\n)+)`\\}'
                ]
            }
        }
    }
});

export default defineConfig({
    plugins: [stylifyPlugin, react()]
});

The last step, open the src/main.jsx and add path to stylify.css:

// ...
import './stylify.css'

Styling the website

If yout copy the code bellow into the src/App.jsx and run yarn dev you will get a styled Hello World! 🎉 text:

export default function App() {
    return (
        <div className="text-align:center margin-top:100px font-size:42px">
            Hello World! 🎉
        </div>
    );
}

Stylify watches any change in the files that matches mask in the bundle files and generates css into the src/stylify.css.

If you add for example color:blue the CSS will be automatically updated 🎉.

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

Components

To avoid bloated templates with utilities, you can use 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',
  title: 'text-align:center margin-top:100px font-size:42px'
/stylify-components
*/
export default function App() {
    return (
        <div class="container">
            <div className="title">Hello World! 🎉</div>
        </div>
    );
}

Variables

If you like clean code, you also want avoid hardcoded values in selectors. Variables can be defined the same way as components:

/*
stylify-variables
  titleFontSize: '42px',
  containerWidth: '800px'
/stylify-variables

stylify-components
  container: 'max-width:$containerWidth margin:0__auto',
  title: 'text-align:center margin-top:100px font-size:$titleFontSize'
/stylify-components
*/
export default function App() {
    return (
        <div class="container">
            <div className="title">Hello World! 🎉</div>
        </div>
    );
}

Building for production

If you run yarn build + yarn preview, the jsx markup will be mangled to this:

export default function App() {
    return (
        <div class="_7tcrv">
            <div className="_88io">Hello World! 🎉</div>
        </div>
    );
}

The css is shortened too:

:root {--titleFontSize: 42px;--containerWidth: 800px;}
._bcda8,._7tcrv{max-width:800px}
._m0vnad,._7tcrv{margin:0 auto}
._1vegb8,._88io{text-align:center}
._jimir,._88io{margin-top:100px}
._qe393,._88io{font-size:42px}
