多个“[HMR]等待来自WDS的更新信号...”控制台输出webpack配置中的每个条目

Question

对于common.entry对象中的每个条目，我将以下内容打印到控制台（我的webpack.config.js中有3个条目）。这是期望的输出吗？

webpack.config.js

const path              = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const merge             = require('webpack-merge');
const validate          = require('webpack-validator');
const parts             = require('./lib/parts');

const TARGET            = process.env.npm_lifecycle_event;

const PATHS = {
    app: path.join(__dirname, 'app'),
    test: path.join(__dirname, 'app', 'test.css'),
    style: [
        path.join(__dirname, 'app', 'main.css')
    ],
    build: path.join(__dirname, 'build'),
};

const common = merge(
    {
        entry: {
            app: PATHS.app,
            style: PATHS.style,
            test: PATHS.test
        },
        output: {
            path: PATHS.build,
            filename: '[name].js'
        },
        resolve: {
            extensions: ['', '.js', '.jsx']
        },
        plugins: [
            new HtmlWebpackPlugin({
                title: 'Webpack demo'
            })
        ]
    }
);

var config;

// console.log(JSON.stringify(common,null,2));

switch(TARGET) {
    case 'build':
        config = merge(
            common,

            parts.setFreeVariable(
                'process.env.NODE_ENV',
                'production'

                name: 'vendor',
                entries: ['react']
            }),
            parts.minify(),
            parts.extractCSS(PATHS.style)
        );
        break;
    default:
