如何在我的angular 5项目中添加"webpack.config.vendor.js“文件

const webpack = require('webpack');
const path = require('path');

module.exports = {
  entry: {
    vendor: [
      'rxjs',
      '@angular/core',
      '@angular/common',
      '@angular/forms',
      '@angular/http',
      '@angular/platform-browser',
      '@angular/platform-browser-dynamic',
      // 添加其他需要打包的第三方库
    ]
  },
  output: {
    path: path.join(__dirname, 'dist'),
    filename: '[name].bundle.js',
    library: '[name]_[hash]'
  },
  plugins: [
    new webpack.DllPlugin({
      name: '[name]_[hash]',
      path: path.join(__dirname, 'dist', '[name]-manifest.json')
    })
  ]
};

"options": {
  "vendorChunk": false
}

"scripts": {
  "build:vendor": "webpack --config webpack.config.vendor.js",
  "build": "ng build && npm run build:vendor"
}

npm run build

<script src="vendor.bundle.js"></script>
