🔴 eslint-config-next v16 requires ESLint >=9.0.0 but project pins ESLint ^8.56.0

Upgrading eslint-config-next from ^15.0.0 to ^16.0.0 introduces an unmet peer dependency. All versions of eslint-config-next@16.x require eslint >= 9.0.0, but the project specifies "eslint": "^8.56.0" which resolves to 8.57.1 in the lockfile.

Peer dependency mismatch details

The npm info output confirms every eslint-config-next@16.x release declares { eslint: '>=9.0.0' } as a peer dependency. The project's package.json:28 specifies "eslint": "^8.56.0" and the lockfile confirms it resolves to 8.57.1.

This mismatch can cause:

  • pnpm install warnings or errors about unmet peer dependencies (depending on pnpm strictness settings)
  • Runtime lint failures or unexpected behavior since eslint-config-next@16 is designed for ESLint 9's flat config system, which is fundamentally different from ESLint 8's .eslintrc-based configuration
  • The project has no ESLint config files (no .eslintrc* or eslint.config.* found), so the actual linting setup may already be broken or unused at the root level

Impact: The lint script (turbo lint) may fail or produce incorrect results when eslint-config-next@16 is loaded with ESLint 8.

Prompt for agents 
In package.json, the eslint-config-next dependency was bumped to ^16.0.0 which requires eslint >=9.0.0, but the eslint dependency on line 28 is still ^8.56.0. Either:
1. Revert eslint-config-next back to ^15.0.0 (line 29), OR
2. Upgrade eslint from ^8.56.0 to ^9.0.0 (line 28) AND migrate the ESLint configuration to ESLint 9's flat config format (eslint.config.js/eslint.config.mjs). Also check that all other eslint plugins and configs (eslint-config-standard, eslint-config-turbo, eslint-plugin-import, etc.) are compatible with ESLint 9.
