preact-cli-postcss

Removes default postcss config and instead will use postcss.config.js

Install it via npm:

npm install preact-cli-postcss

yarn:

yarn add preact-cli-postcss --dev

And include in your project by creating a preact.config.js

const preactCliPostCSS = require('preact-cli-postcss');

export default function (config, env, helpers) {
	preactCliPostCSS(config, helpers);
}
