Basic usage

Using postcss JavaScript API

const postcss = require('postcss');
const cssJanus = require('postcss-janus');

postcss( [ cssJanus(options) ] );

Using postcss-loader in Webpack

rules: [
    {
        test: /\.css$/,
        use: [
            { loader: 'style-loader' },
            { loader: 'css-loader' },
            {
                loader: 'postcss-loader',
                options: {
                    ident: 'postcss',
                    plugins: () => [ require('postcss-janus')(options) ]
                }
            }
        ]
    }
]

Options

Directives

Directives should be added as comments before a CSS rule block or a property, e.g:

/* @ruleDirective */
.example {
    /* @propertyDirective */
    color: white;
}

If you do not use PostCSS, add it according to official docs and set this plugin in settings.
