Summary

This PR upgrades ESLint from v9.39.3 to v10.0.1, accompanied by a follow-up fix commit (abb2d90) that works around a compatibility issue with eslint-plugin-react in ESLint v10.

Overall: LGTM with one minor observation.

---

eslint.config.ts — Fix Commit (abb2d90)

+ { settings: { react: { version: "19" } } },

Correct approach. ESLint v10 removed the deprecated context.getFilename() API. eslint-plugin-react's React version auto-detection relies on this API, causing a crash during linting. Setting an explicit version: "19" bypasses the auto-detection entirely.

This is the correct workaround as documented in the Next.js issue #89764. Once eslint-plugin-react releases a fix for the removed API, this setting can remain in place (it's a valid explicit config anyway).

---

package.json — Dependency Bump

- "eslint": "9.39.3",
+ "eslint": "10.0.1",

Clean, straightforward version bump. No issues here.

---

pnpm-lock.yaml — Notable Changes

The lock file updates are consistent with the version bump. A few notable observations:

Node.js engine requirement tightened:
ESLint v10's internal packages (e.g., @eslint/config-array, @eslint/core, @eslint/plugin-kit) now require ^20.19.0 || ^22.13.0 || >=24 instead of ^18.18.0 || ^20.9.0 || >=21.1.0. This is more restrictive but aligns with the project's Node.js 24 requirement in package.json — no issue here.

Removed legacy package @eslint/eslintrc:
ESLint v10 drops the legacy eslintrc-style config compatibility shim entirely. Since this project uses the flat config format (eslint.config.ts), this is expected and correct.

Removed @eslint/js:
ESLint v10 has reorganized its internal structure; @eslint/js is no longer listed as a separate dependency in the lock file (it's now bundled). This is an internal ESLint change with no impact on usage.

New: eslint-visitor-keys@5.0.1 and @types/esrecurse@4.3.1:
These are new transitive additions from ESLint v10. Both are expected and benign.

acorn updated from 8.15.0 → 8.16.0: Minor patch bump, expected.

No Issues Found

• No security concerns
• No missing tests (this is a pure dependency upgrade)
• The eslint-plugin-react crash workaround is correct and well-documented in the commit message with a reference link
• All peer dependency resolutions in the lock file look correct (eslint-config-next, eslint-config-prettier, eslint-plugin-simple-import-sort all resolve against ESLint 10)
