Upgrade to PostCSS 8

The PostCSS 7’ `postcss.plugin` method has been deprecated in favour of manually created function returning an object containing various event handling functions like `Once`, `Declaration`, `Rule` and many more. ```patch - module.exports = postcss.plugin('postcss-dark-theme-class', (opts = {}) => { - checkOpts(opts) - return (root, result) => { root.walkAtRules(atrule => { … }) - } - }) ``` ```patch + module.exports = (opts = {}) => { + checkOpts(opts) + return { + postcssPlugin: 'postcss-dark-theme-class', + Once (root, { result }) { root.walkAtRules(atrule => { … }) + } + } + } + module.exports.postcss = true ``` https://evilmartians.com/chronicles/postcss-8-plugin-migration
