Astro

Integrating Vanilla Extract with Astro is done with the help of the Vite plugin.

Installation

bash

npm install @vanilla-extract/css
npm install @vanilla-extract/vite-plugin --save-dev

Setup

Add Vanilla Extract Vite plugin to the Astro configuration:

import { defineConfig } from 'astro/config';
import { vanillaExtractPlugin } from '@vanilla-extract/vite-plugin';

// https://astro.build/config
export default defineConfig({
  vite: {
    plugins: [vanillaExtractPlugin()]
  }
});

You'll then be able to use style and other APIs in .css.ts files.

// button.css.ts

import { style } from '@vanilla-extract/css';

export const button = style({
  padding: '0.5rem 1rem',
  border: 'none',
  borderRadius: '0.25rem',
  color: 'white',
  background: '#333'
});

And now you can reference styles in your Astro component:

tsx

//  Button.astro

---
import { button } from './button.css'
---

<button class={button}>Click Me!</button>

Configuration
