Aesthetic - Core API

Unifies a design system and a CSS-in-JS engine into a powerful framework agnostic API.

import { Aesthetic } from '@aesthetic/core';
import dayTheme from './design/system/dayTheme';
import nightTheme from './design/system/nightTheme';

const aesthetic = new Aesthetic({
    defaultUnit: 'px',
    deterministicClasses: false,
});

// Register a theme (provided by the design system)
aesthetic.registerDefaultTheme('day', dayTheme);

// Register a theme that has global styles
aesthetic.registerTheme('night', nightTheme, (css) => ({
    '@root': css.mixin('root', {
        backgroundColor: css.var('palette-neutral-bg-base'),
        height: '100%',
    }),
}));

// Create a component style sheet
const styleSheet = aesthetic.createStyleSheet((css) => ({
    button: {
        textAlign: 'center',
        display: 'inline-block',
        padding: css.var('spacing-df'),
    },
}));

// Render the style sheet into the document
const classNames = aesthetic.renderStyleSheet(styleSheet);

Though the core API is framework agnostic and can be used stand-alone, it's encouraged to use a framework integration package for better ergonomics.
