useMutation - updating a single entry in onMutate
I am trying to follow the tutorial on tanstack for doing optimistic updates. I cannot make their example work in my app for updating a single entry in the onMutate function. I am following the guide here: https://tanstack.com/query/latest/docs/framework/react/guides/optimistic-updates for "Updating a single todo".
React Query provides two ways to optimistically update your UI before a mutation has completed. You can either use the onMutate option to update your cache directly, or leverage the returned variables to update your UI from the useMutation result.
