ESLint Config

Overview

This recipe walks through scaffolding a standalone npm package that exports a flat ESLint config. It layers TypeScript-ESLint, import sorting, and a curated rule set tuned for Next.js and Node.js backends. The result is a single @your-org/eslint-config dependency.

Core Config

The entry point merges three presets into a single flat config array. Consumers just reference the package name in their own eslint.config.js.

import tseslint from 'typescript-eslint'
import imports from 'eslint-plugin-import-x'

export default tseslint.config(
  tseslint.configs.recommended,
  {
    plugins: { import: imports },
    rules: {
      'import/order': ['error', {
        'newlines-between': 'always',
        alphabetize: { order: 'asc' }
      }],
      '@typescript-eslint/no-unused-vars': 'error',
      'no-console': 'warn'
    }
  }
)

Next Steps

• Publish the package to your private npm registry.
• Add a .eslintrc.json preset for legacy projects.
• Wire a pre-commit hook that runs eslint --fix.
