🔴 ESLint 10 drops legacy .eslintrc config format used by this project

Upgrading ESLint from v8 to v10 will break all linting in this project. The repository uses .eslintrc (legacy JSON configuration) at the root and in examples/webhooks-nextjs/.eslintrc, but ESLint 10 completely removed support for the legacy eslintrc configuration system.

Root Cause and Impact

ESLint 9 deprecated the legacy config system (.eslintrc.* files), and ESLint 10 removed it entirely. This project relies on multiple legacy-only features:

  • .eslintrc JSON config files (.eslintrc:1-30 and examples/webhooks-nextjs/.eslintrc:1-14)
  • The env key ("env": { "browser": true, "node": true }) at .eslintrc:8-11
  • The extends key with string-based config names at .eslintrc:3-7
  • The plugins key as a string array at .eslintrc:2
  • eslint-config-standard (package.json:31) which is designed for the legacy config system and has no flat config equivalent

After this upgrade, running eslint (e.g., via pnpm lint in any package) will fail because ESLint 10 won't recognize or load .eslintrc files at all. The project needs to be migrated to the flat config format (eslint.config.js) before upgrading to ESLint 10.

Impact: All linting commands (turbo lint, package-level eslint invocations) will fail.

Prompt for agents
The ESLint upgrade from v8 to v10 cannot be done as a simple version bump. ESLint 10 removed support for the legacy .eslintrc configuration format that this project uses. Before upgrading, you need to:

1. Convert .eslintrc (root) and examples/webhooks-nextjs/.eslintrc to flat config format (eslint.config.js or eslint.config.mjs)
2. Replace the `env` key with `languageOptions.globals` using the `globals` npm package
3. Replace `extends` with direct imports of config objects
4. Replace `plugins` string array with imported plugin objects
5. Replace `eslint-config-standard` (package.json line 31) with a flat-config-compatible alternative (e.g., `neostandard` or manually replicate the rules)
6. Verify all other eslint plugins/configs in devDependencies (eslint-config-turbo, eslint-plugin-import, etc.) have flat config support

Alternatively, revert this change and keep eslint at ^8.56.0 until the config migration is done.

🚩 Peer dependency conflicts with eslint-config-standard and eslint-config-next

Beyond the .eslintrc format incompatibility reported as a bug, two ESLint config packages in package.json declare peer dependencies that explicitly exclude ESLint 10:

  • eslint-config-standard@17.1.0 requires eslint: ^8.0.1 (lockfile confirms this)
  • eslint-config-next@15.4.6 requires eslint: ^7.23.0 || ^8.0.0 || ^9.0.0 (lockfile confirms this)

pnpm's autoInstallPeers: true setting allowed the lockfile to resolve without errors, but these packages may exhibit runtime issues or missing/broken rules when paired with ESLint 10. Even if the flat config migration is done, these specific package versions would need to be upgraded to versions that officially support ESLint 10.

🚩 Several other devDependencies may also be incompatible with ESLint 10

Beyond the core .eslintrc incompatibility, several other devDependencies in package.json are likely incompatible with ESLint 10:

  • eslint-config-standard (package.json:31): This package is designed for the legacy config system and has been effectively abandoned in favor of neostandard. It declares eslint peer dependency as ^8.0.1.
  • eslint-config-turbo (package.json:32): v2 may not support ESLint 10's flat config.
  • eslint-plugin-import (package.json:33): Historically slow to adopt new ESLint versions; eslint-plugin-import v2 may not declare ESLint 10 as a supported peer.
  • @typescript-eslint/eslint-plugin and @typescript-eslint/parser (package.json:26-27): At ^8.0.0, these should support flat config, but compatibility with ESLint 10 specifically depends on the minor version resolved.

These would likely produce peer dependency warnings or runtime errors even if the config format issue were resolved.

🚩 Node.js engine requirement mismatch with ESLint 10.4.0

The lockfile shows eslint@10.4.0 requires engines: {node: ^20.19.0 || ^22.13.0 || >=24}, but the current environment runs Node.js v20.18.1 (as seen from the error output). Node 20.18.1 does not satisfy ^20.19.0. Depending on CI node version and whether strict engine checks are enabled in pnpm (engine-strict), this could cause installation failures in CI or developer environments. Worth verifying what Node version CI uses.

🚩 No other package.json or config changes accompany this major version bump

This PR only changes the eslint version specifier in the root package.json. A major version bump from v8 to v10 (skipping v9) typically requires accompanying changes: migrating .eslintrc to eslint.config.*, updating incompatible shared configs/plugins, and potentially adjusting lint scripts that use deprecated CLI flags (e.g. eslint -f unix in packages/livekit-rtc/package.json). The absence of these changes suggests this may have been an automated dependency update (e.g. Renovate — renovate.json exists in the repo) that wasn't reviewed for breaking changes.
