Description

After Angular and Angular Universal updates can’t get AppServerModuleNgFactory from main.js bundle to render Angular to string and to make some our magic:).

We have such code in our server.ts now and before v9 update

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

but angular’s builder can’t resolve the path, all folders stay like it was

Also, I noticed that the main.js bundle doesn’t export AppServerModuleNgFactory and in the previous version it was.

🔬 Minimal Reproduction

My server.ts:

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

import * as express from 'express';
import * as fs from 'fs';
import { ngExpressEngine } from '@nguniversal/express-engine';

import { AppServerModule, renderModuleFactory } from '../src/main.server';
import { replaceAngularBundles } from './shared/utils';

/* does'n work */
const { AppServerModuleNgFactory } = require('./dist/server/main');
/* does'n work */

const server = express();
const template = fs.readFileSync('browser/index.html').toString();
const port = process.env.PORT || 4000;

server.engine('html', ngExpressEngine({
  bootstrap: AppServerModule,
}));

server.get('*', (req, res) =>  renderModuleFactory(AppServerModuleNgFactory, {
  url: req.url,
  document: template,
  extraProviders: [
    { provide: 'request', useFactory: () => req, deps: [] },
  ]
}).then(html => res.send(replaceAngularBundles(html))));

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

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

run command: ng run project-name:server:production
