Provide a service to find component by name

🚀 feature request

Relevant Package

This feature request is for @angular/core

Description

I have a scenario in my framework that I should find ComponentType by it’s name and then create it. In Angular 8 I used ComponentFactoryResolver["_factories"] to find component. (Component added to EntryComponent)

But in Ivy there is no _factories in ComponentFactoryResolver.

I tried to use _r3Injector.injectorDefTypes and then ["ɵmod"].declarations for each module. It was OK in development but in production mode declarations is always empty.

After that I tried to use directiveRegistry of TView . But I understood that only components stay on directiveRegistry that used.

Describe the solution you’d like

I think it would be nice if there is a service that metadata of modules and components can be accessible via it.

Describe alternatives you’ve considered

An alternative can be provide a service to register these types and then use them.

Can we get a solution for this in Angular Ivy? It’s a much required feature I feel.

We are using a way to have dynamic components by extending modules to provide components that should be available via selectors. Hope this helps.
