Serving multiple Angular Universal apps in one Express app

I have two distinct Angular apps made with angular-cli, both already modified to run on a node.js server via Angular Universal following Angular's tutorial, but the example can only serve one app.

The example creates a view engine:

app.engine('html', (_, options, callback) => {
  renderModuleFactory(AppServerModuleNgFactory, {
    // Our index.html
    document: template,
    url: options.req.url,
    // DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
    extraProviders: [
      provideModuleMap(LAZY_MODULE_MAP)
    ]
  }).then(html => {
    callback(null, html);
  });
});

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

Since each app has a different index.html file, I'd need to create two view engines, but how can I tell Express to use one engine in one route and another engine in another route? In other words, how can I map app1 to /app1 and app2 to /app2?

Express application can mount multiple sub-applications to different endpoints:

const app1 = express();
const app2 = express();
...
app.use('/app1', app1);
app.use('/app2', app2);
app.listen(3000);

Sub-applications can have their own settings and shouldn't be listened.
