安装依赖

npm -i eslint eslint-plugin-import eslint-config-airbnb-base

配置webpack.config.js

在webpack.config.js中配置loader

module: {
  rules: [{
    test: /\.js$/,
    exclude: /node_modules/,
    loader: 'eslint-loader',
    options: {
      // 自动修复 eslint错误
      fix: true,
    },
   }]
}

配置eslintConfig

在package.json中配置eslintConfig，应用airbnb-base规则

"eslintConfig": {
  "extends": "airbnb-base"
}

在代码中忽略eslint语法检查的代码上面添加注释

airbnb-base规则

4.3 Use array spreads … to copy arrays.

const itemsCopy = […items];

4.4 To convert an iterable object to an array, use spreads … instead of Array.from

const foo = document.querySelectorAll(‘.foo’); const nodes = […foo];

4.5 Use Array.from for converting an array-like object to an array.

const arrLike = { 0: ‘foo’, 1: ‘bar’, 2: ‘baz’, length: 3 }; arr = Array.from(arrLike);

4.6 Use Array.from instead of spread … for mapping over iterables, because it avoids creating an intermediate array.

const baz = Array.from(foo, bar);
