uniapp configuration eslint + prettier

Background: The Alipay applet project created by vue/cli is used
Not much talk about serving

• Install eslint, because the project is built by cli, so use vue add @vue/eslint directly
  vue add @vue/eslint
  Then choose the style according to your preference, here I choose prettier
• Configure.eslintrc.js
  Create a new file .eslintrc.js in the project root directory and configure the rules according to your needs

module.exports = {
    root: true,
    env: {
        node: true,
    },
    globals: {
        uni: "readonly",
        my:"readonly"
    },
    extends: ["plugin:vue/essential", "eslint:recommended", "@vue/prettier"],
    parserOptions: {
        parser: "babel-eslint",
    },
    rules: {
        "no-console": process.env.NODE_ENV === "production" ? "warn" : "off",

    },
};

• Configure files that eslint does not need to check.eslintignore
  Create a new file .eslintignore in the root directory and configure it according to actual needs

/utils
/subpackage/utils
/node_modules
/postcss.config.js
/babel.config.js

• Finally configure.prettierrc.js
  Create a new .prettierrc.js file in the root directory and configure it according to actual needs

//配置 prettier  。prettierrc.js
module.exports = {
  // 单行最大长度
  printWidth: 100,
  // 设置编辑器每一个水平缩进的空格数
  tabWidth: 2,
  // 在句尾添加分号
  semi: true,
  // 使用单引号
  singleQuote: true,
  jsxSingleQuote: true,
  // 在任何可能的多行中输入尾逗号。
  trailingComma: 'all',
  // 在对象字面量声明所使用的的花括号后（{）和前（}）输出空格
  bracketSpacing: true,
  // 在多行JSX元素最后一行的末尾添加 > 而使 > 单独一行（不适用于自闭和元素）
  jsxBracketSameLinte: false,
  // 为单行箭头函数的参数添加圆括号。
  alwaysParens: 'always',
  // 行结束
  endOfLine:"auto",
  vueIndentScriptAndStyle: true, //是否缩进Vue 文件中的代码<script>和<style>标签
  htmlWhitespaceSensitivity:'ignore',//HTML 空白敏感度
};

• The last step is to modify the lint command in the package.json file to

   "lint": "eslint --fix --ext .js,.vue src",

  When there is a problem, it will report an error.
  
  Don't worry about these warnings, execute npm run lint and it will fix it yourself
