How to get notified when certain mutations succeed

[krachtstefan]

I try to keep my question as short as possible. Considering the circumstances in a web app:

• I have an endpoint that fetches a list of notifications (like the ones you have behind a notification bell)
• I have around 50 mutations in my app
• 10 of these mutations can cause some notifications to (dis)appear, so I need to refetch whenever they are successful

I would like to configure the refetches in one place (near that notification component) and avoid going to all 10 onSuccess callbacks and trigger a refetch. What could be a good strategy? Is there a way to have an onSuccess callback for certain mutationKeys.

Thanks in advance for your input!

you could use the new useMutationState hook in v5 to listen to all mutations, then find out when they have all finished and then fire an effect that invalidates.

otherwise, the global onSuccess callback of the MutationCache can also do it.

I stumbled upon useMutationState in the V5 release notes and was wondering if this could be a solution. But I was just not sure.

Thank's for clarifying @TkDodo and congrats to the v5 release, I will update very soon!
