重新加载页面时，Angular Universal崩溃（路由不起作用）

Question

刚刚在firebase上部署了Angular Unversal Web应用程序。应用程序内部的所有路由都可以正常工作，但是当尝试从外部访问它们时，服务器返回错误。这是错误消息：

这是server.ts文件：

(global as any).WebSocket = require('ws');
(global as any).XMLHttpRequest = require('xhr2');
global['TextTrackCueList'] = null;
global['KeyboardEvent'] = null;

import 'zone.js/dist/zone-node';

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

const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');

var app = express()

const {AppServerModuleNgFactory, LAZY_MODULE_MAP, ngExpressEngine, provideModuleMap} = require('./dist/server/main');

app.engine('html', ngExpressEngine({
  bootstrap: AppServerModuleNgFactory,
  providers: [
    provideModuleMap(LAZY_MODULE_MAP)
  ]
}));

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

app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
app.get('*', (req, res) => {

  res.render('index', { req });
});

长话短说。只需在export]前添加var app = express();
