xstate

for example we name actions in such a way that common one are shared ...

updateXXXX -> updates the context, uses assign function

saveXXXX -> Save to database; it is unique to server and client

handleXXX -> it is some third party calls, it is unique to server and client

and we have context processing this is where changes that need for next action dependency. For example we need to save some updates to reservation will be saved as processing.changesToSave and if action sequence has saveToDatabase then it will look for it and save.
