Global mutation onSuccess function

[Bdg0o]

Hi,

I’m trying to execute a onSuccess function on all the mutations of my app.

Using the queryClient default options (queryClient.setDefaultOptions({ mutations: { onSuccess : … } }) works well, but if I have to specify a onSuccess in a specific mutation, the default function is overriden.
Is there a way to keep the default onSuccess function in addition to the onSuccess that is defined in the mutation ?

One way to do it would be to use queryClient.getDefaultOptions to get the default onSuccess function and to call it in the mutation onSuccess, but I would be forced to do this in all my mutations that have a onSuccess function. Not very convenient.

Thanks for your help,

Antoine.

To answer myself. This can be done via MutationCache (https://tanstack.com/query/v4/docs/reference/MutationCache#global-callbacks). I didn't know of this class !
