Install

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

Usage

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

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

export default defineESLintConfig()

Add scripts lint in package.json and config prettier:

{
  "scripts": {
    "lint": "eslint .",
    "lint:fix": "eslint . --fix"
  },
  "prettier": "@ntnyq/prettier-config"
}

VSCode Config

{
  "eslint.enable": true,
  "prettier.enable": true,
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": "explicit"
  },
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "eslint.validate": [
    "vue",
    "html",
    "yaml",
    "toml",
    "json",

    "json5",
    "markdown",

}

Lint changed files only

1. Add dependencies

  },
  "nano-staged": {
    "*.{js,ts,cjs,mjs,jsx,tsx,vue,md,html,json,toml,yml,yaml}": "eslint --fix"
