Aspnetcore-angular-universal: appId // make sure this matches with your Server NgModule

Don't quite get this.

What should it match?
The selector of the Server NgModule bootstrapped component?

This is just used to match up the IDs created during the server-render with the client-rendered version so that styles get reused/etc, otherwise you'd get a flicker from it.

Hope that helps!

But where in the Server NgModule is this set? Can't find it anywhere 😕

Is it this one?
