Postcss only one :root

A PostCSS plugin to remove all instances of “:root” but one from a stylesheet.

This plugin is very basic. It removes all instances of :root except for the first it encounters from a processed stylesheet (if present). I built this as I used automatical localised imports for my Webpack scss files, which occured in duplicate references to the :root selector variables.

Otherwise, you probably have no use for this plugin. You should run this plugin after running [postcss-custom-properties]

Installation

npm install --save postcss-only-one-root

Example

variables.scss

:root {
    --color-blue: blue;
}

file.a.scss

@import "./variables";
.something-1 {
    color: var(--color-blue);
}

file.b.scss

@import "./variables";
.something-2 {
    color: var(--color-blue);
}

Output

:root {
    color-blue: blue
}
.something-1 {
    color: blue;
    color: var(--color-blue);
}
.something-2 {
    color:blue;
    color: var(--color-blue);
}

Usage

See the PostCSS documentation for examples on how to use this plugin in different environments. This plugin takes no options.
