How to Combine and Handle Multiple Mutations with Shared Success and Error Handling in React Query?

I have two mutations (2 fetch put request) in the same react component, i have modals i show for both on success and onerror, how can i combine those two mutations since i dont want to show one modal for each mutation.

if they fire at the same time, you can have mutation that fires two requests

I have the both mutation in a submit function in the component right now, you mean i should combine them in to one mutation?

yep

Do you have a link to a code example or any documentation about that?

I mean ... a mutationFn is just a function that returns a Promise. A Promise can be one request or multiple requests (with Promise.all)

mutationFn: () => {
  return Promise.all([makePostRequest1(), makePostRequest2()]
}

mutationFn: () => {
  return Promise.all([makePostRequest1(), makePostRequest2()]
}

So basically i just create a function like you show and call the mutations from there? What if i need to get parameters sent to each request?

send them in as variables. I don't know your use-case and "what if" games are pretty tiring. You can show a minimal reproduction in codesandbox or stackblitz and I'll take a look

@TkDodo 🔮 This seems to be working.

 const confirm = () => {
    mutate({ param1, param2, param3 });
  };

export const useUpdateItem = () => {
  return useMutation({
    mutationFn: ({ param1, param2, param3}) => {
      return Promise.all([
        request1(param1),
        request2(param2, param3)
      ]);
    }
  });
};

 const confirm = () => {
    mutate({ param1, param2, param3 });
  };

export const useUpdateItem = () => {
  return useMutation({
    mutationFn: ({ param1, param2, param3}) => {
      return Promise.all([
        request1(param1),
        request2(param2, param3)
      ]);
    }
  });
};

Does it looks correct to you?
