eslint 相关积累

一、注释不要的扫描段落，特别是拷贝的网上的代码

    /* eslint-disable */
    var codeNotOk;
    /* eslint-enable */

二、 注释不要扫描的单行代码

var thing = new Thing(); // eslint-disable-line no-use-before-define
// eslint-disable-next-line no-use-before-define
var thing = new Thing();

三、eslint 等级
“off”, “warn”, “error”
不重要的off, warn警告

四、批量扫描

// 扫描某个js文件夹下的所有js
$  eslint  webapp/js/**.js
// 扫描某个js文件夹及其子文件夹下的所有js
$  eslint  webapp/js/**/**.js

五、.eslintrc.json放在相关的js目录下，当前.eslintrc.json示例：

{
  "extends": "airbnb-es5",
  "rules": {
    "func-names": "off",
    "no-console": "off",
    "no-multi-str": "off",
    "linebreak-style": "off",
    "quotes": "off",
    "space-before-function-paren": "off",
    "no-param-reassign": "warn",
    "consistent-return": "off",
    "no-shadow": "off",
    "no-else-return": "off",
    "one-var": "off",
    "guard-for-in": "warn",
    "no-unused-vars": "warn",
    "spaced-commnet": "warn",
    "eol-last": "warn",
    "padded-blocks": "warn",
    "spaced-comment": "off",
    "yoda": "off"
  }
}
