[Question] Module Encapsulation / Dependency about modular-monolith-laravel HOT 1 OPEN

@boxxroom Thank you for watching the talk! I also got inspired by Luke's talk about actions and I think contracts in my talk can be implemented as actions as well.

To answer your question, yes, the order module is dependent on the inventory module. However, you can change the inventory module's implementation without having to change the order module since the order module only depends on the contracts (i.e. interface and DTO) of the inventory module. The idea is that modules are "loosely" coupled so that we can independently change the module's implementation as long as the contract remains the same.

An alternative approach is dispatching an event from a module and another module handles the event. This way, a module wouldn't need to depend on the interfaces and DTOs.
