partialRefetch as an option

[jfrolich]

The partialRefetch option is not available at the moment. Would it be possible to make it available?

Actually not having partial refetch enabled will cause issues if you have mutations that return less attributes than a query. The mutation will actually hang the app. I think for useQuery it's probably good to enable partialRefetch by default (it should be default for Query as well, but Apollo didn't enable the default for backwards compatibility reasons).

Hello @trojanowski! This is actually very necessary functionality according to react-apollo docs:

The default value is false for backwards-compatibility's sake, but should be changed to true for most use-cases.

FWIW linking corresponding code and valuable comment: https://github.com/apollographql/react-apollo/blob/22f8ebf52b26b348d6be905d5b7fbbfea51c1541/src/Query.tsx#L461

This can be a workaround to manually implement the partialRefetch behaviour.

  // workaround for partialRefetch
  useEffect(() => {
    if (loading) return;
    if (data) return;
    if (error) return;
    // if there's no data, no error or loading, it must be stuck at `partial` state.
    refetch();
  }, [!!data, !!loading, !!error]);
