Creating a place to centralize our broader plans for 2026, consolidate open ideas and discussions, and taskify progress towards v1.0.0. See also (#1355)

Conveniences

One of the common complaints about StyleX is that it leans verbose certain use cases. These are ideas to address that.

• [experiment] Inline styles #1357
• stylex.props → sx() transform #1359
• npx create-stylex-app #1395
• [babel-plugin] Soft validation for disallowed properties #1423

Features

• [feature] stylex.env to provide constants and utility functions to StyleX #1358
• [babel-plugin] Create a set of custom "logical" property functions #1232
• [Fixes / Enhancements] defineConsts improvements #1174
• Create experimental APIs for nested defineVars, defineConsts, and createTheme APIs #1363
• [Feature] Bring back stylex.attrs for non-react frameworks. #1365
• [Feature] Consider bringing back a fixed stylex.include API #1366

Website + docs

Most of the docs need an overhaul, and the examples should be updated to use the unplugin whenever possible, or require a general update (as with NextJS). Doc improvements are especially important to support LLM readiness.

• [docs] Improve the StyleX playground #732
• [docs] Redesign the StyleX website #1361
• [docs] Add LLM context files #1256
• Documentation improvements:
  • [docs] Add docs for processStylexRules to API section #1061
  • Update the NextJS example and documentation #1364

CSS bundling improvements

Improvements and optimizations to CSS bundling and build process

• Post-process generated CSS to remove unused variables and inline constants #717
• CSS normalization (dedupe rules, group at-rules) (nice to have)
• Performance improvements to application-order #1482
• Baseline CSS resets and overrides

Dev tools

• [feat] StyleX Dev Tools Extension #1401 (and possibly VS Code extension)
• ESLint improvements (valid-styles, sort keys, stylelint integration)
  • [eslint-plugin] Integrate Stylelint into valid-styles #1203
  • [eslint-plugin] sort keys rule should sort object keys when applying fix #787
• Library codemods for migration from other frameworks

React Strict DOM

• Native polyfills (via RSD)
  • stylex.when.* APIs
  • inline styles functions
  • stylex.include if we decide to bring it back
