    Aesthetic - CSS-in-JS Style Engine

    Build Status npm version npm deps

    A low-level, high-performance, atomic-based CSS-in-JS solution. Can be used stand-alone but has been designed to power additional abstractions or APIs.

    import { createClientEngine } from '@aesthetic/style';
    // Instantiate a client side (DOM) engine
    const engine = createClientEngine();
    // Render a style decleration into individual atomic class names
    const className = engine.renderRule({
    	margin: 0,
    	textAlign: 'center',
    	color: 'var(--color)',
    	backgroundColor: 'transparent',
    	border: '2px solid #eee',
    	':hover': {
    		borderColor: '#fff',
    	'@media': {
    		'(max-width: 600px)': {
    			display: 'block',
    	'@variants': {
    		'size:small': {
    			fontSize: 14,
    			padding: '4px 10px',
    		'size:default': {
    			fontSize: 16,
    			padding: '6px 12px',
    		'size:large': {
    			fontSize: 18,
    			padding: '8px 14px',
    className.result; // -> a b c d e f g
    className.variants; // -> [h i, j k, l m]
