Is there a way to pass the query client into a mutationOptions onSuccess call?

[eprig]

I am wondering if there is a way to have the global query client that gets used automatically for things like useQuery to be passed as context to a mutationOptions object. This would be useful for updating the query cache from the mutation responses.

Yes. In current TanStack Query v5, mutation callbacks receive a MutationFunctionContext as their final argument, and its client field is the QueryClient that owns the mutation:

const options = mutationOptions({
  mutationFn: saveTodo,
  onSuccess: (data, _variables, _onMutateResult, { client }) => {
    client.setQueryData(['todo', data.id], data)
  },
})

You can use the same client for invalidation:

onSuccess: async (_data, _variables, _onMutateResult, { client }) => {
  await client.invalidateQueries({ queryKey: ['todos'] })
}

So you do not need to pass the client into the options factory manually. If your installed version does not expose the fourth argument, it predates the mutation context added in #9615 and needs to be upgraded.

Thanks, I couldn't find it in the docs
