Install

npm i eslint typescript @ntnyq/eslint-config -D

yarn add eslint typescript @ntnyq/eslint-config -D

pnpm add eslint typescript @ntnyq/eslint-config -D

bun add eslint typescript @ntnyq/eslint-config -D

Usage

Highly recommended using eslint.config.mjs as the config file :

// @ts-check

import { defineESLintConfig } from '@ntnyq/eslint-config'

export default defineESLintConfig(
  // Options here
  {
    // Enable a config
    svgo: true,
    // Disable a config
    jsdoc: false,
    vue: {
      // Overrides built-in rules
      overrides: {
        'vue/slot-name-casing': 'off',
      },
    },
  },
  // Optional user configs here
  [
    {
      files: ['**/utils/*.ts'],
      rules: {
        'antfu/top-level-function': 'error',
      },
    },
  ],
)

Add scripts lint in package.json:

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

<summary>💼 Intergrated with Prettier, VSCode, husky and nano-staged</summary>
## Prettier config > Feel free to use your own prettier config. Install prettier and setup your prettier config:

shell
npm i prettier @ntnyq/prettier-config -D

shell
yarn add prettier @ntnyq/prettier-config -D

shell
pnpm add prettier @ntnyq/prettier-config -D

shell
bun add prettier @ntnyq/prettier-config -D

js
// prettier.config.mjs
// @ts-check

import { defineConfig } from '@ntnyq/prettier-config'

export default defineConfig({
  // Custom options if needed
  printWidth: 100,
  trailingComma: 'none',
  overrides: [
    {
      files: ['**/*.html'],
      options: {
        singleAttributePerLine: false,
      },
    },
    {
      files: ['**/*.{css,scss,less}'],
      options: {
        singleQuote: false,
      },
    },
  ],
})

## VSCode Config

json
{
  "eslint.enable": true,
  "prettier.enable": true,
  "editor.formatOnSave": true,
  "prettier.configPath": "./prettier.config.mjs",
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": "explicit",
    "source.organizeImports": "never",
    "source.sortImports": "never"
  },
  "eslint.validate": [
    "vue",
    "yaml",
    "toml",
    "json",
    "jsonc",
    "json5",
    "markdown",
    "javascript",
    "typescript",
    "javascriptreact",
    "typescriptreact"
  ]
}

## Lint changed files only ### 1. Add dependencies

shell
pnpm add husky nano-staged -D

### 2. Config in package.json

json
{
  "scripts": {
    "prepare": "husky"
  },
  "nano-staged": {
    "*.{js,ts,cjs,mjs,jsx,tsx,vue,md,svg,yml,yaml,toml,json}": "eslint --fix",
    "*.{css,scss,html}": "prettier -uw"
  }
}

### 3. Add a Git hook

shell
echo "nano-staged" > .husky/pre-commit
