Release v5.24.0 (2026-10-04) · Rel1cx/eslint-react

What's Changed

react-x/set-state-in-effect: more value shapes are recognized as ref-derived setState arguments: interpolations in template literals (ex: setData(`${ref.current}`)), tagged templates (both the quasi and a ref-derived tag), object and array literals (ex: setData({ value: ref.current })), and spreads (ex: setData({ ...ref.current })) — previously these fell through to the default case and were reported. (#1988)

@local/eff: added predicate combinators and type guards synced with effect, and migrated call sites across the workspace to them. (#1989)
react-x/set-state-in-effect, react-x/set-state-in-render, and react-x/use-memo: reworked to the fact-based implementation pattern — fact collection (collect.ts), provenance resolution (origins.ts), and violation inference (effects.ts) are now separate modules, with lib.ts replaced by a pure-AST helpers.ts; set-state-in-effect again classifies a hook name configured as both additionalStateHooks and additionalEffectHooks as a state hook first. (#1983, #1985, #1986)
react-x/use-state: aligned the nested-expression collectors' visitor keys to callee-first order, matching eslint-visitor-keys; no behavior change. (#1988)
Migrated package unit tests to the shared @local/testkit helpers. (#1987)
Renamed message ids to kebab-case across all plugins. (#1984)
Bumped fumadocs-core and fumadocs-ui to 16.15.18, fumadocs-mdx to 15.4.6, lucide-react to 1.50.0, and @types/node to 26.6.4.
