What's Changed

✨ New

  • react-x/no-unused-props: improved prop usage detection. Props parameters with default values (ex: function Component(props: Props = defaultProps)) are now unwrapped and analyzed, props aliased to a local variable (ex: const alias = props) are tracked through the alias, and template literals without substitutions (ex: props[`foo`]) are recognized as static prop keys. (#2021)

🐞 Fixes

  • react-x/no-unused-props: a component whose used prop keys cannot be fully determined (ex: it passes the whole props object to another function) now marks all of its declared props as used, so a props declaration shared with another fully analyzable component is no longer reported as unused. (#2021)
  • react-x/set-state-in-effect: ref-derived values that reach the setState argument through assignment statements (rather than the declaration initializer) are now recognized; only writes that lexically precede the use and live in the use's own function or an ancestor count. (#2027)
  • react-x/set-state-in-effect: parameters of a helper invoked from the effect setup are now treated as ref-derived when the call-site argument is ref-derived, matched per call site by parameter definition. (#2027)
  • react-x/set-state-in-effect: a .current read rooted at a function parameter is now recognized as a ref read (ex: setReferenceElement(anchor?.current) where anchor is a RefObject prop); previously only parameters named ref or ending in Ref were recognized. (#2027)
  • react-x/no-unused-class-component-members: public methods (including function-valued properties) of an exported class component are no longer reported as unused, as they may be part of the component's imperative API invoked by consumers through refs. Data fields, private/protected members, and members of non-exported classes are still reported. (#2024)

🏗️ Internal

  • Ordered message ids by first usage and unified default/suggestion message id naming across react-dom, react-jsx, react-web-api, and react-x rules. (#2022)
