Update of Angular 8 looks inadequate #66

Is this upgrade guide compatible?

https://github.com/angular/universal/blob/master/docs/v8-upgrade-guide.md

I'll take a look at this shortly

Thank you for your quick reply.

This will reproduce.

$ git clone https://github.com/kamilmysliwiec/universal-nest.git
$ cd universal-nest && npm i
$ npm run build:ssr && npm run serve:ssr

# An error occurs when transitioning to the speakers.

Due to this problem, I can not set dynamic title and meta on the server side.

  constructor(private title: Title, private meta: Meta) { }

  ngOnInit() {
    this.title.setTitle('Some Title');
    this.meta.addTag({ name: 'description', content: 'Some description' });
  }

Fixed in @nestjs/ng-universal@2.0.0. I have also updated universal-starter repo :) For existing apps, update all packages + follow this:
https://github.com/angular/universal/blob/master/docs/v8-upgrade-guide.md (only 1 bullet) + remove enableProdMode() from main.ts
