Investigation Results — Closing as Premature

I investigated this fully. The upgrade to ESLint v10 cannot succeed yet due to an unresolved upstream issue.

Root Cause

ESLint v10 removed context.getFilename() (deprecated since v8). The copy of eslint-plugin-react bundled inside eslint-config-next still calls contextOrFilename.getFilename() in lib/util/version.js:31, causing a hard crash:

TypeError: Error while loading rule 'react/display-name': contextOrFilename.getFilename is not a function

Upstream Status

Package	Version	Status
eslint-plugin-react	7.37.5 (latest)	No eslint v10 support — peerDeps cap at ^9.7
eslint-config-next	16.2.2 (latest)	Bundles eslint-plugin-react@^7.37.0, no v10-compatible version available

The fix exists in two open/draft PRs on jsx-eslint/eslint-plugin-react:

• #3972 (DRAFT, "Changes requested"): changes context.getFilename() → context.filename in version.js and jsx-filename-extension.js — this is the actual runtime fix needed
• #3979 (Open): follow-up that only updates CI config and peerDep declaration — does not include the runtime fix

Neither PR has been merged or released. The vercel/next.js issue tracker is tracking this at #89764 (still open).

Why npm overrides Won't Help

The crash comes from eslint-config-next's own nested copy of the plugin (eslint-config-next/node_modules/eslint-plugin-react). Even forcing a top-level override would leave the nested copy intact. A proper fix requires eslint-config-next itself to be updated once the upstream plugin ships a patched release.

Recommendation

Close this PR and re-open once eslint-plugin-react >= 7.37.6 (or a new minor) ships with the context.filename fix and eslint-config-next picks it up. Track upstream at:

• Update types and RuleContext deprecations jsx-eslint/eslint-plugin-react#3972
• [ESLint v10]: TypeError: contextOrFilename.getFilename is not a function when running ESLint v10 vercel/next.js#89764

[jonathanperis]

Closing as premature — see investigation comment above. Will need to reopen once eslint-plugin-react ships eslint v10 support and eslint-config-next picks it up.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
