js语法检查eslint

const { resolve } = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  entry: './src/js/index.js',
  output: {
    filename: 'js/built.js',
    path: resolve(__dirname, 'build')
  },
  module: {
    rules: [
      /*
        语法检查： eslint-loader  eslint
          注意：只检查自己写的源代码，第三方的库是不用检查的
          设置检查规则：
            package.json中eslintConfig中设置~
              "eslintConfig": {
                "extends": "airbnb-base"
              }
            airbnb --> eslint-config-airbnb-base  eslint-plugin-import eslint
      */
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'eslint-loader',
        options: {
          // 自动修复eslint的错误
          fix: true
        }
      }
    ]
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './src/index.html'
    })
  ],
  mode: 'development'
};
