v2.0.0

Major Changes

• #123 f26409e Thanks @tenphi! - Unified hash-based class names across RSC, SSR, and client. Same cache key now produces the same class name in all environments, enabling cross-environment style deduplication. Replaces the heavy SSRCacheState transfer with a lightweight class-name-list via window.__TASTY__.

  SSR/RSC fixes included:

  • Fix missing tokens on pages without RSC-rendered tasty components. The globalThis.__tasty_rsc_internals_emitted__ flag leaked across requests in the same Node.js process; internals (tokens, @property, @font-face, @counter-style) are now emitted exclusively by the SSR collector.
  • Fix duplicate global CSS when RSC and SSR paths both emit internals in Next.js App Router. The SSR collector now skips internals already emitted by the RSC inline-style path.
  • Fix CSS class name collisions during client-side navigation in Next.js App Router. RSC inline styles used sequential counters (r0, r1, …) that reset on every request; replaced with content-based hashing (djb2) so identical content always maps to the same name.
  • Auto-skip global CSS injection on client when <style data-tasty-ssr> is detected, eliminating the need for typeof window === 'undefined' guards in configure() calls.

  Internal SSR API changes (not part of the public API):

  • SSRCacheState type removed — replaced by plain string[] class lists.
  • ServerStyleCollector.getCacheState() replaced by getRenderedClassNames().
  • window.__TASTY_SSR_CACHE__ replaced by window.__TASTY__.
  • hydrateTastyCache() deprecated in favor of hydrateTastyClasses() (the old function still works as a compat shim).
  • Class name format changed from t{number} to t{base36hash}.

Minor Changes

• #119 af8bf8a Thanks @tenphi! - Add presets and globalStyles options to configure(). presets is a shorthand for generateTypographyTokens() that merges generated tokens under explicit tokens. globalStyles is a Record<string, Styles> that applies Tasty styles to arbitrary CSS selectors across all rendering modes. Both options are also available in plugins and zero-runtime config. Typography preset fields now accept state maps for responsive/theme-aware values.

Patch Changes

• #119 8a7a342 Thanks @tenphi! - Derive TastyZeroConfig from TastyConfig via Omit to keep the two types in sync automatically. This also widens TastyZeroConfig to accept colorSpace, properties, and boolean values in replaceTokens — options that were previously only available in the runtime config.

• #123 841767c Thanks @tenphi! - Fix overlapping and duplicate CSS selectors produced by the condition simplifier.

  • Fix overlapping selectors when default and custom-state token values coincide but other state values differ.
  • Fix overlapping selectors for compound state tokens by adding consensus resolution and making inner OR branches exclusive during CSS materialization.
  • Fix complementary factoring for compound state conditions, eliminating duplicate selectors when token values match across state combinations.
  • Eliminate duplicate token CSS rules when multiple states map to the same value. Tokens now generate a single rule instead of redundant duplicates. Also fixes absorption law so A | (A & B) correctly simplifies to A regardless of condition complexity.

• #119 a642337 Thanks @tenphi! - Change default letterSpacing in typography presets from '0' to 'normal'. The previous default could override inherited letter-spacing; 'normal' matches the browser default.
