Using Svelte Add

The easiest way to set up Tailwind CSS inside of an existing SvelteKit project is with svelte-add.

terminal
npx svelte-add@latest tailwindcss

You’re done! πŸ˜„

This creates a app.postcss file which is imported inside the root layout.

src/routes/+layout.svelte
<script>
	import '../app.postcss'
</script>

<slot />

Automatic Class Sorting With Prettier

Make sure you have the Prettier extension installed and it’s the default formatter in your VS Code settings.

settings.json
"editor.formatOnSave": true,
"editor.defaultFormatter": "esbenp.prettier-vscode"

Skip this step if you have prettier in your project.

terminal
npm i -D prettier prettier-plugin-svelte

Install the Prettier plugin for Tailwind CSS.

terminal
npm i -D prettier-plugin-tailwindcss

After you save it should sort the classes.

routes/+page.svelte
<!-- Before -->
<button class="text-white px-4 sm:px-8 py-2 sm:py-3 bg-sky-700 hover:bg-sky-800">
  ...
</button>

<!-- After -->
<button class="bg-sky-700 px-4 py-2 text-white hover:bg-sky-800 sm:px-8 sm:py-3">
  ...
</button>
