Changelog

[0.24.0] - 2024-01-02

Fixed

• Fix regression in previous implementation that increased memory usage per extraction, leading to slower performance over time

Added

Add patterns to config.staticCss

Changed

• Boost style extraction performance by moving more work away from postcss
• Using a hashing strategy, the compiler only computes styles/classname once per style object and prop-value-condition pair
• Fix the special [*] rule which used to generate the same rule for every breakpoints, which is not what most people need (it's still possible by explicitly using responsive: true).

const card = defineRecipe({
  className: 'card',
  base: { color: 'white' },
  variants: {
    size: {
      small: { fontSize: '14px' },
      large: { fontSize: '18px' },
    },
    visual: {
      primary: { backgroundColor: 'blue' },
      secondary: { backgroundColor: 'gray' },
    },
  },
})

export default defineConfig({
  // ...
  staticCss: {
    recipes: {
      card: ['*'], // this

      // was equivalent to:
      card: [
        // notice how `responsive: true` was implicitly added
        { size: ['*'], responsive: true },
        { visual: ['*'], responsive: true },
      ],

      //   will now correctly be equivalent to:
      card: [{ size: ['*'] }, { visual: ['*'] }],
    },
  },
})

Here's the diff in the generated CSS:

  @layer _base {
    .card {
      color: var(--colors-white);
