postcss-style-docs

PostCSS plugin for dynamically adding documentation to styles.

The postcss-style-docs pluin will walk through your input CSS and create a map of styles to documentation blocks as a message output.

/**
 * @docs
 * This is a documentation block for the .foo class
 * it can be multiple lines
 */
.foo {
  /* Input example */
}

.foo {
  /* Output example */
}

Usage

Step 1: Install plugin:

npm install --save-dev postcss postcss-style-docs

Step 2: The postcss-style-docs plugin works best when manually calling postcss.process which enables users to get data out of the plugin:

import postcss from 'postcss';
import { getDocs, styleDocsPlugin } from './lib/cjs/index';

const inputCSS = `
/**
 * @docs
 * We're doing something really fancy and our users are going
 * to love it.
 */
.something-fancy {
  color: tomato;
}

/** @docs Make it pop */
.something-fancy--pop {
  background: papayawhip;
}
`;

const { css, messages } = await postcss([
  styleDocsPlugin()
]).process(inputCSS, { from: undefined });

const docs = getDocs(messages);

console.log(docs.size); // 2
console.log(docs.get('.something-fancy')); // 'We're doing something really fancy and our users are going to love it'
console.log(docs.get('.something-fancy--pop')); // 'Make it pop'
