What's Changed

🐞 Fixes

• react-x/no-missing-key: elements with a spread attribute are no longer reported as missing key. (#2086)

• react-jsx/no-useless-fragment: fragments with a spread attribute are no longer reported. (#2086)

• react-dom/no-dangerously-set-innerhtml-with-children: empty expression containers ({} and comments) no longer count as children. (#2086)

• react-dom/no-script-url: namespaced attributes such as xlink:href are now checked for javascript: URLs. (#2086)

• react-dom/no-void-elements-with-children: comment-only/empty containers and newline-only formatting whitespace no longer count as children. (#2086)

• react-web-api/no-leaked-event-listener: cyclic alias chains no longer cause infinite recursion when resolving a signal option. (#2085)

• children supplied through a statically resolvable computed key in a createElement props object is now detected. (#2086)

  Affected rules:

  • react-jsx/no-children-prop
  • react-jsx/no-children-prop-with-children

🪄 Improvements

• JSX and createElement rules no longer resolve spread props, since a spread's contents are unknown; only direct attributes and properties are inspected. (#2086)

  Affected rules:

  • react-x/no-missing-key
  • react-jsx/no-children-prop
  • react-jsx/no-children-prop-with-children
  • react-jsx/no-useless-fragment
  • react-dom/no-dangerously-set-innerhtml
  • react-dom/no-dangerously-set-innerhtml-with-children
  • react-dom/no-missing-button-type
  • react-dom/no-missing-iframe-sandbox
  • react-dom/no-string-style-prop
  • react-dom/no-unsafe-iframe-sandbox
  • react-dom/no-unsafe-target-blank
  • react-dom/no-void-elements-with-children

🏗️ Internal

• @eslint-react/jsx / @eslint-react/ast: rewrote the jsx module around direct-attribute descriptors and parseCreateElementCall (dropping its @eslint-react/var and ts-pattern dependencies and spread-property resolution), added Extract.getJSXName, and made getChildren return meaningful children. (#2086)

• @eslint-react/var: added resolveOriginChain, isProvenanceEqual, and hasDefault, expanded resolveObjectType and createImportLookup (isModuleBinding replaces hasNamespace), made isValueEqual identity-only, and removed resolveBindingTarget/BindingTarget. (#2085)

• Rules now use the shared callee, JSX-name, and resolution helpers and unwrap AssignmentPattern defaults inline; react-x/no-unknown-property also caches its lookups per React version. No behavior change. (#2085, #2086)

  Affected rules:

  • react-x/globals
  • react-x/immutability
  • react-x/no-array-index-key
  • react-x/no-unknown-property
  • react-x/no-unused-props
  • react-x/purity
  • react-x/set-state-in-effect
  • react-x/unstable-exhaustive-deps
  • react-jsx/no-namespace
  • react-dom/no-find-dom-node
  • react-dom/no-flush-sync
  • react-dom/no-hydrate
  • react-dom/no-render
  • react-dom/no-render-return-value
  • react-dom/no-use-form-state
