Three weeks ago, we open-sourced StyleX. Since then, we've been diligently fixing bugs and making improvements. Here are some of the highlights:


  • The amount of JavaScript generated after compilation has been further reduced.
  • Added support for some previously missing CSS properties to the ESLint plugin.
  • Added support for using variables in stylex.keyframes.
  • Removed the code for style injection from the production runtime, reducing the size of the runtime by over 50%.
  • Added Flow and TypeScript types for the Rollup Plugin.
  • Added the option to use CSS Layers in all bundler plugins.
  • TypeScript will now auto-complete style property names.
  • Bundler plugins will now skip files that don't contain StyleX, resulting in faster build times.

Bug Fixes

  • Fixed a bug where the ESLint plugin was sometimes unable to resolve local constants used for Media Queries and Pseudo Classes.
  • Resolved a bug where the runtime injection of styles in dev mode would sometimes fail.
  • Addressed a bug where styles injected at runtime during development would sometimes suffer from specificity conflicts.
  • The TypeScript types for Theme will now correctly throw an error when applying a theme for the wrong VarGroup.

In addition to these, we've made other improvements to the types and documentation. I want to extend my gratitude to all the contributors for their pull requests. ♥️

Happy New Year!
