如果想使用最新版本的，可以新增一个命令

"scripts": {
    "update": "ncu -u && yarn"
  },

配置规则 在根目录创建 .eslintrc.js

// @ts-check
const { defineConfig } = require('eslint-define-config')
module.exports = defineConfig({
  root: true,
  env: {
    browser: true,
    node: true,
    es2021: true,
  },
  parser: 'vue-eslint-parser',
  parserOptions: {
    parser: '@typescript-eslint/parser',
    ecmaVersion: 'latest',
    sourceType: 'module',
    jsxPragma: 'React',
    ecmaFeatures: {
      jsx: true,
    },
  },
  extends: [
    'plugin:vue/vue3-recommended',
    'plugin:@typescript-eslint/recommended',
    'prettier',
    'plugin:prettier/recommended',
  ],

      },
    ],
    'no-unused-vars': [

          normal: 'never',
          component: 'always',
        },
        svg: 'always',
        math: 'always',
      },
    ],
    'vue/multi-word-component-names': 'off',
  },
})

在默写文件或页面禁用eslint 根目录创建 .eslintignore

/dist/*
/node_modules/**
/public/*

配置prettier规则 在根目录创建 prettier.config.js

// prettier.config.js
module.exports = {
  printWidth: 100,
  semi: false,
  vueIndentScriptAndStyle: true,
  singleQuote: true,
  trailingComma: 'all',
  proseWrap: 'never',
  htmlWhitespaceSensitivity: 'strict',
  endOfLine: 'auto',
}

某些页面禁用 prettier 根目录创建 .prettierignore

/dist/*
/node_modules/**
/public/*

使用eslint，我这里是借助开发工具 WebStorm，其他开发工具可以自行搜索对应的功能

使用prettier
