Angular 7 通用，ReferenceError : window is not defined

Question

我正在使用 Angular 7 和 Angular Universal 制作 SSR，但是当我使用来自第三方的 Fusioncharts 时，我在运行此脚本时遇到此错误 npm run build:ssr && npm run serve:ssr

ReferenceError: window is not defined
    at Object.undefined.module.exports.module.exports (C:\Users\ridho.fauzan\Documents\angular-app\bizhare-frontend\desktop\dist\server.js:161938:807)

我尝试在 server.ts 文件上使用多米诺骨牌，但它仍然无法正常工作

这是我的 server.ts 文件

import 'zone.js/dist/zone-node';
import {enableProdMode} from '@angular/core';
// Express Engine
import {ngExpressEngine} from '@nguniversal/express-engine';
// Import module map for lazy loading
import {provideModuleMap} from '@nguniversal/module-map-ngfactory-loader';

import * as express from 'express';
import {join} from 'path';

// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();

// Express server
const app = express();

const PORT = process.env.PORT || 8086;
const DIST_FOLDER = join(process.cwd(), 'dist/browser');

// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main');

// Our Universal express-engine (found @ https://github.com/angular/universal/tree/master/modules/express-engine)
app.engine('html', ngExpressEngine({
  bootstrap: AppServerModuleNgFactory,
  providers: [
    provideModuleMap(LAZY_MODULE_MAP)
  ]
}));

app.set('view engine', 'html');
app.set('views', DIST_FOLDER);

// Example Express Rest API endpoints
// app.get('/api/**', (req, res) => { });
// Serve static files from /browser
app.get('*.*', express.static(DIST_FOLDER, {
  maxAge: '1y'
}));

// All regular routes use the Universal engine
app.get('*', (req, res) => {
  res.render('index', { req });
});

// Start up the Node server
app.listen(PORT, () => {
  console.log(`Node Express server listening on http://localhost:${PORT}`);
});

Angular 9 ssr nguniversal这就是我定义的方式 window在 server.ts它对我有用。

//server.ts

import 'zone.js/dist/zone-node';
import {enableProdMode} from '@angular/core';
import { ngExpressEngine } from '@nguniversal/express-engine';
import * as express from 'express';
import { join } from 'path';
import { AppServerModule } from './src/main.server';
import { APP_BASE_HREF } from '@angular/common';
import { existsSync } from 'fs';

enableProdMode();

// The Express app is exported so that it can be used by serverless Functions.
export function app() {
  const server = express();
  const distFolder = join(process.cwd(), 'dist/browser');
  const indexHtml = existsSync(join(distFolder, 'index.original.html')) ? 'index.original.html' : 'index';
  const domino = require('domino');
  const win = domino.createWindow(indexHtml);
  // mock
  global['window'] = win;
  global['document'] = win.document;
  global['navigator'] = win.navigator;
  // Our Universal express-engine (found @ https://github.com/angular/universal/tree/master/modules/express-engine)
  server.engine('html', ngExpressEngine({
    bootstrap: AppServerModule,
  }));

  server.set('view engine', 'html');
  server.set('views', distFolder);

  // Example Express Rest API endpoints
 // Serve static files from /browser
  server.get('*.*', express.static(distFolder, {
    maxAge: '1y'
  }));

  // All regular routes use the Universal engine
  server.get('*', (req, res) => {
    res.render(indexHtml, { req, providers: [{ provide: APP_BASE_HREF, useValue: req.baseUrl }] });
  });

  return server;
}

function run() {
  const port = process.env.PORT || 4000;

  // Start up the Node server
  const server = app();
  server.listen(port, () => {
    console.log(`Node Express server listening on http://localhost:${port}`);
  });
}

// Webpack will replace 'require' with '__webpack_require__'
// '__non_webpack_require__' is a proxy to Node 'require'
// The below code is to ensure that the server is run only when not requiring the bundle.
declare const __non_webpack_require__: NodeRequire;
const mainModule = __non_webpack_require__.main;
const moduleFilename = mainModule && mainModule.filename || '';
if (moduleFilename === __filename || moduleFilename.includes('iisnode')) {
  run();
}

export * from './src/main.server';

我不知道在哪里 domino模块来自 b/c 我没有安装它，但看起来它来自 angular cli设置时 nguniversal 🤷‍♂️
