Summary

Fixes #20204.

Dependency array parsing crashes when it encounters optional-chained function calls, e.g. props?.attribute.method().

Given:

useEffect(() => {}, [someObject?.optionalField.method()]);

Expected:

  • React Hook useEffect has a complex expression in the dependency array. Extract it to a separate variable so it can be statically checked.

Actual:

  • Cannot read property 'type' of undefined
  • No lint errors are displayed due to linter crash

Test Plan

Unit tests:

  • Added missing test for checking function call as dependency: [props.method()]
  • Added test validating fix. Contains optional-chained function call: [props?.attribute.method()]

Regression:

  • Linted 164 repositories before and after the fix. The only change was that the previously crashing file was no more crashing. Every other lint warning was as before.

I tried installing version 0.0.0-experimental-7b84dbd16 from npm, which is supposed to contain this fix, but looks like it doesn't. Did CI fail to pick correct commit or do I misunderstand something?

You can see for yourself in https://registry.npmjs.org/eslint-plugin-react-hooks/-/eslint-plugin-react-hooks-0.0.0-7b84dbd16.tgz, compiled file package/cjs/eslint-plugin-react-hooks.development.js does not contain these changes.

Isn’t 7b84d an earlier commit? Wait another day for a release.

Oh, sorry, I must've confused something while comparing hashes in my head. Thanks!
