We’re trying to implement a user onboarding path that needs to be able to reverse to the last state on failure.
We’ve found a few libraries that could be potential solutions, however they seem relatively inactive. We considered using Sage, which implements the saga pattern, as well as a few state machine libraries: fsmx and machinery. Fsmx seems to be the most active library as of now.
Do you normally use one of these (or a similar) library, or do you implement it using gen_statem or gen_fsm?
