remix-postcss

Use your PostCSS Config in Remix

---

Install

# npm
npm install remix-postcss
npm install postcss --dev

# yarn
yarn add remix-postcss
yarn add -D postcss

---

Informations

This Package will read out all PostCSS-Config file types from your Remix-App Root dirctory. (!!! Currently only plugins are used !!!)

Since we're reprocessing the Files again and again there will be duplicate rules because they have been reprocessed. Due to this we've added postcss-discard-duplicates as a default Plugin. If this conflicts with your PostCSS-Config read further down about configuring remix-postcss.

Usage

- Global processing

This Package is a bit special in how it works, but it's easy to setup

/app/entry.server.tsx

import { remixPostcss } from "remix-postcss";

...

export default function handleRequest(
  request: Request,
  responseStatusCode: number,
  responseHeaders: Headers,
  remixContext: EntryContext
) {
  remixPostcss(remixContext);
  ...

- Options

remixPostcss(remixContext, {
  /**
   * Disables the "postcss-discard-duplicates" PostCSS Plugin
   */
  disableDiscardDuplicates: false, // default: false
});

And you're finished!

How it works

• Reads all Modules from the Remix Context
• Takes their exported links
• Runs those Files through PostCSS and saves them again
