What version of Oxlint are you using?

latest (main branch, commit 553e638)

What command did you run?

oxlint -c .oxlintrc.json

What does your .oxlintrc.json (or oxlint.config.ts) config file look like?

{
  "plugins": ["react"],
  "rules": {
    "react-hooks/exhaustive-deps": "warn"
  }
}

What happened?

When property reads like obj.a and obj.b occur inside an IIFE (Immediately Invoked Function Expression) within a hook callback, oxlint incorrectly reports obj as a missing dependency and obj.a / obj.b as unnecessary. ESLint's react-hooks/exhaustive-deps does not report any error for the same code.

Reproduction:

import { useMemo } from 'react';

function MyComponent({ obj, flag }: { obj: { a: string; b: string }; flag: boolean }) {
  return useMemo(() => {
    return (() => {
      return flag ? obj.a : obj.b;
    })();
  }, [obj.a, obj.b, flag]);
}

oxlint output:

⚠ React Hook useMemo has a missing dependency: 'obj'.
  Either include it or remove the dependency array.
⚠ React Hook useMemo has an unnecessary dependency: 'obj.a'.
  Either exclude it or remove the dependency array.
⚠ React Hook useMemo has an unnecessary dependency: 'obj.b'.
  Either exclude it or remove the dependency array.

Expected: No warnings. [obj.a, obj.b, flag] is the correct dependency array.

The same issue also applies to function expression IIFEs:

function MyComponent({ obj }) {
  return useMemo(() => {
    return (function() {
      return obj.a;
    })();
  }, [obj.a]);
}
