@weapp-tailwindcss/postcss

The /syntax, /transform, and /plugin subpaths separate syntax helpers, CSS transformations, and PostCSS generation orchestration. Existing root exports remain available.

This package is the CSS processing core of weapp-tailwindcss. It handles PostCSS AST transforms, selector compatibility, platform differences, and Tailwind output post-processing for mini programs.

Repeated CSS Comparisons

For repeated comparisons against one CSS string, createCssRuleMatcher(baseCss) provides contains(css) and filter(css) with reusable, lazy comparison indexes. It preserves the semantics of containsCssAfterMinify and filterExistingCssRules. Create a new matcher when the base CSS changes; release it after the batch.

Native compiler

The isolated @weapp-tailwindcss/postcss/native entry provides compileNativeCss(css, options) for CSS-to-native style translation. It returns rules, variables, and warnings. React Native manifest IDs, Tailwind generation, and runtime integration remain in @weapp-tailwindcss/react-native; importing its /runtime entry does not load this compiler.

Experimental transforms

Experimental LightningCSS selector transforms live under @weapp-tailwindcss/postcss/experimental/lightningcss. They are not exported from the stable root. The @weapp-tailwindcss/experimental/lightningcss facade loads the LightningCSS engine; the PostCSS subpath itself only imports its types. The optional peer is needed only by consumers of these experimental types.
