Adding TailwindCSS to Svelte components in a Django app

This is a follow-up guide for how to add Tailwind styles to your Svelte components in your Django app. You can also read part one which is about how to add the Svelte components to your Django app in the first place.

We essentially use Rollup for that Svelte setup, so we need to make sure that our Tailwind classes are detected within the Svelte files and the resulting CSS is injected in the JS files generated for the Svelte components.

The short version

cd mysite/svelte
pnpm i -D tailwindcss postcss rollup-plugin-postcss autoprefixer

The rollup.config.js file:

const postcss = require('rollup-plugin-postcss');

// ...
{
  plugins: [
    postcss({
      plugins: {
        'tailwindcss/nesting': {},
        tailwindcss: {},
        autoprefixer: {},
      },
    }),
    // ... Svelte
  ],
}
// ...

Got that info from the Tailwind docs, which also include instructions on how to integrate with SCSS, etc., but no instructions for Rollup specifically.
