Dynamic module vs global module?

Definition:

A dynamic module creates its module definition from supplied configuration, making a feature reusable in different environments. A global module makes its exported providers broadly available after registration. Dynamic describes configuration behavior; global describes visibility, so these are independent properties.

Key points:

• A dynamic module returns module settings and providers based on configuration.

• A global module makes exported providers available across the app after registration.

• Use global modules sparingly so dependencies stay easy to follow.

• A configured database or integration module can expose a provider without every consumer knowing how it was constructed.

Interview point:

• Prefer explicit imports for feature dependencies so the app remains understandable and independently testable.
