Question 1

How to integrate Mobius with Android ViewModel?

Accepted Answer

Use the mobius-android module to connect a MobiusLoop to Android components, typically by creating a ViewModel that manages the loop and exposes state observables to the UI, similar to the sample TODO app.

Question 2

Mobius vs MVI or Redux for Android?

Accepted Answer

Mobius is similar to MVI but with a stricter focus on side-effect isolation via effect handlers. Compared to Redux, it's more tailored to JVM/Android and seamlessly integrates with RxJava or Coroutines, whereas Redux is often web-centric.

Question 3

How to handle asynchronous effects in Mobius with coroutines?

Accepted Answer

Use the mobius-coroutines module, which provides suspend function-based effect handlers and Flow-based event sources, with configurable execution policies for sequential or concurrent effects, as described in the README.

Question 4

Is Mobius suitable for server-side Java applications?

Accepted Answer

Yes, the core is pure Java and can run on any JVM, but it's optimized for client-side state management with side-effects, so other frameworks like Akka might be more common for server use cases.

Question 5

What's the performance overhead of Mobius loops?

Accepted Answer

Mobius adds minimal runtime overhead as it's lightweight, but the structured pattern can increase boilerplate and memory usage for complex state graphs. Profiling is recommended for performance-critical apps.

Question 6

How to test Mobius effect handlers that make network calls?

Accepted Answer

Use the mobius-test utilities to mock effects and verify outcomes, or inject test dependencies like fake repositories into effect handlers to simulate network responses without actual I/O.
