Eslint with monorepo

Question

Hello, I have an eslint-config package (packages/eslint-config) with a base file that contains the base of the eslint configs. I have a nextjs config that takes my base config. When I use my config in my nextjs app (apps/web) it tells me this error: The Next.js plugin was not detected in your ESLint configuration.packages/eslint-config/base.jsimport { resolve } from 'node:path'
import eslintjs from '@eslint/js'
import eslintConfigPrettier from 'eslint-config-prettier'
import onlyWarn from 'eslint-plugin-only-warn'
import turbo from 'eslint-plugin-turbo'
import tseslint from 'typescript-eslint'

const project = resolve(process.cwd(), 'tsconfig.json')

export default tseslint.config(
  eslintjs.configs.recommended,
  tseslint.configs.recommendedTypeChecked,
  eslintConfigPrettier,
  turbo.configs['flat/recommended'],
  {
    languageOptions: {
      parserOptions: {
        project,
        tsconfigRootDir: process.cwd()
      }
    }
  },
  {
    plugins: { onlyWarn }
  },
  {
    ignores: ['dist/**', 'eslint.config.js']
  }
)
