angular - 开发 webpack 构建花费大量时间

Question

我正在开发一个 Angular 4 项目（通过 JHipster 创建），这需要花费大量时间在启动时构建项目以及在对任何文件进行微小更改后重新构建。

构建 appox 至少需要 10 分钟。4500 个子模块。

const webpack = require('webpack');
const writeFilePlugin = require('write-file-webpack-plugin');
const webpackMerge = require('webpack-merge');
const BrowserSyncPlugin = require('browser-sync-webpack-plugin');
const WebpackNotifierPlugin = require('webpack-notifier');
const path = require('path');

const utils = require('./utils.js');
const commonConfig = require('./webpack.common.js');

const ENV = 'development';

module.exports = webpackMerge(commonConfig({
  env: ENV
}), {
  devtool: 'eval-source-map',
  devServer: {
    contentBase: './target/www',
    proxy: [{
      context: [
        '/uaa',
        /* jhipster-needle-add-entity-to-webpack - JHipster will add entity api paths here */
        '/api',
        '/management',
        '/swagger-resources',
        '/v2/api-docs',
        '/h2-console',
        '/auth'
      ],
      target: 'http://127.0.0.1:8080',
      secure: false
    }],
    watchOptions: {
      ignored: /node_modules/
    }
  },
  entry: {
    polyfills: './src/main/webapp/app/polyfills',
    global: './src/main/webapp/content/scss/global.scss',
    main: './src/main/webapp/app/app.main'
  },
  output: {
    path: utils.root('target/www'),
    filename: 'app/[name].bundle.js',
    chunkFilename: 'app/[id].chunk.js'
  },
  module: {
    rules: [{
        test: /\.ts$/,
        enforce: 'pre',
        loaders: 'tslint-loader',
        exclude: ['node_modules', new RegExp('reflect-metadata\\' + path.sep + 'Reflect\\.ts')]
      },
      {
        test: /\.ts$/,
        loaders: [
          'angular2-template-loader',
          'awesome-typescript-loader'
        ],
        exclude: ['node_modules/generator-jhipster']
      },
      {
        test: /\.scss$/,
        loaders: ['to-string-loader', 'css-loader', 'sass-loader'],
        exclude: /(vendor\.scss|global\.scss)/
      },
      {
        test: /(vendor\.scss|global\.scss)/,
        loaders: ['style-loader', 'css-loader', 'postcss-loader', 'sass-loader']
      },
      {
        test: /\.css$/,
        loaders: ['to-string-loader', 'css-loader'],
        exclude: /(vendor\.css|global\.css)/
      },
      {
        test: /(vendor\.css|global\.css)/,
        loaders: ['style-loader', 'css-loader']
      }
    ]
  },
  plugins: [
    new BrowserSyncPlugin({
      host: 'localhost',
      port: 9000,
      proxy: {
        target: 'http://localhost:9060'
      }
    }, {
      reload: false
    }),
    new webpack.NoEmitOnErrorsPlugin(),
    new webpack.NamedModulesPlugin(),
    new writeFilePlugin(),
    new webpack.WatchIgnorePlugin([
      utils.root('src/test'),
    ]),
    new WebpackNotifierPlugin({
      title: 'JHipster',
      contentImage: path.join(__dirname, 'logo-jhipster.png')
    })
  ]
});

我尝试谷歌搜索并找到解决方案，但无济于事。
