Is there anything like APP_INITIALIZER for lazy loaded modules in Angular?

Question

I am looking for something that lets me execute code when a certain module is initialized. This module is lazy loaded in my application. The APP_INITIALIZER only works for the app initialization process (once at beginning starting at the main module that is bootstrapped).

I cannot use the constructor of the lazy loaded module since my service returns a Promise and I need the response synchronously for working in this lazy loaded module.

Maybe you can try Angular resolver. Helpful links: codeburst.io/understanding-resolvers-in-angular-736e9db71267; alligator.io/angular/route-resolvers — miselking

Use a resolver. Resolvers are perfect for what you need.

This is great to use on component level. Is there something similar to use on module level?

@PhilippEscher One workaround you could use would be to have a module landing view that would use a resolver, it would load all the module level settings and redirect to the requested view.

@PhilippEscher Another idea is to use a module level constructor: bennadel.com/blog/… I have not used this but it looks like a promising workaround.
