How do I access the response headers?

[atresnjo]

I have a mutation which returns a Content-Disposition header with the filename, etc. But my generated mutation returns only a string, any way to get access to the response headers? Thanks for the great package!

The mutations generated by this library do not return headers. Instead of using the generated mutation hook, create your own hook.
The following is an example using the axios client. (The problem is that the types generated by the Hey API do not have headers, though.)

import { addPet } from "../openapi/requests/services.gen";
import {
  AddPetMutationResult,
  UseFindPetsKeyFn,
} from "../openapi/queries";
import { AxiosError } from "axios";
import { AddPetData, AddPetError } from "../openapi/requests/types.gen";

// create your own hook
const { mutate, isError } = useMutation<
    AddPetMutationResult,
    AxiosError<AddPetError>,
    AddPetData
  >({
    mutationKey: [useAddPetKey],
    mutationFn: (options) => addPet(options),
  });


// mutation
mutate(
    {
      body: { name: text },
    },
    {
      onSuccess: (data) => {
           const contentDisposition = data.headers["content-disposition"];
           // do something
      },
    }
  );
