Part of the StyleX SWC Plugin workspace
A high-performance CSS value parser (~28 k lines) providing comprehensive
parsing and validation for CSS properties, types, and at-rules. This was already
an independent crate before the monorepo refactor; it is now a clean leaf with
no internal dependencies beyond stylex-macros.
- Full CSS type coverage: colors, lengths, angles, calc expressions, transform functions, easing, filters, and more
- Flexible parser combinator system (
FlexParser,FlexCombinators) with backtracking support for composable, zero-copy parsing - Media query parsing and transformation with "last media query wins" semantics
via
last_media_query_wins_transform
- Layer: 2 — Domain Leaves
- Depends on:
stylex-macros - Depended on by:
stylex-css,stylex-transform
