What is the difference between lib and get in @module-federation/runtime?

Hey 👋

I'm using @module-federation/runtime@0.2.5 to dynamically load remotes in a runtime.

But I'm having troubles understanding different sharing options in runtime init configuration.

A couple of questions have emerged while working with MF runtime:

1. What's the proper configuration for sharing dependencies in @module-federation/runtime?
2. What is the difference between lib and get? How do they work exactly?
3. Will the dependency be shared between the host and the remotes, if neither lib and get are passed to init?
4. How to clearly confirm that module is really shared between host and remotes? I can see the config on the global window.__FEDERATION__, but how to be sure that there's a single instance of the module fetched, and reused by both parties?

I would really appreciate some clarification, because I couldn't get those answers from the docs.

Thanks a lot!

Lib is synchronous, once it's loaded or an eager factory function. Get is asynchronous, still needs to load the factory.
