How to host two independent applications in Angular4?

Question

Angular

If you add the assembled application to the page after the tag <app-one>, with the tag <app-two>,and add bundles of application 2, then an error occurs at startup

Uncaught Error: Zone already loaded.

How to add two different Angular4 applications to the same page so that they do not conflict? Will this have a big impact on performance?

Answer 1

I see no reason to add several applications to one page, except perhaps for the experiment.
