Thinkbuff's ESLint config preset

Thanks to antfu/eslint-config for the inspiration and reference.

Usage

Requires Node.js >=20.
Requires ESLint >=9.

Install

pnpm i -D eslint @thinkbuff/eslint-config

Create config file (`eslint.config.js`)

See the ESLint docs for more information about extending config files.

ES Module (Recommended)

With "type": "module" in package.json (recommended):

// eslint.config.js
import { defineFlatConfigAsync } from '@thinkbuff/eslint-config'
import { FlatCompat } from '@eslint/eslintrc';

const compat = new FlatCompat();

export default defineFlatConfigAsync({
  astro: true,
  unocss: true,
  // Additional ESlint Flat Config
  extends: [
    {
      files: ['src/**/*.ts'],
      rules: {
        'perfectionist/sort-objects': 'error',
      },
    },
    // Legacy config
    ...compat.config({
      extends: [
        'eslint:recommended',
        // Other extends...
      ],
    }),
  ]
}

CommonJS

// eslint.config.js
const { defineFlatConfigAsync } = require('@thinkbuff/eslint-config')
const { FlatCompat } = require('@eslint/eslintrc')

const compat = new FlatCompat()

module.exports = defineFlatConfigAsync({
  astro: true,
  unocss: true,
  // Additional ESlint Flat Config
  extends: [
    {
      files: ['src/**/*.ts'],
      rules: {
        'perfectionist/sort-objects': 'error',
      },
    },
    // Legacy config
    ...compat.config({
      extends: [
        'eslint:recommended',
        // Other extends...
      ],
    }),
  ]
})

Add script for package.json

For example:

{
  "scripts": {
    "lint": "eslint .",
    "lint:fix": "eslint . --fix"
  }
}
