query context

[correttojs]

Hi,

I'm writing a gql client based on fetch and react-query.

I was considering an example with multiple gql client instances, each of them linked to a different endpoint.

It would be nice to expose a context to share some custom data between the react-query QueryClient and the queryFn (so extending the QueryFunctionContext) and mutationFn. This way, in the above use case, I could define a default endpoint in the scope of the default react query client, and customize it in case I want to access a different endpoint.

The queryFn already works in a similar way, as it can define a default implementation and override it on each useQuery, though it doesn't seem to be flexible enough for my use case

could you elaborate why the default query function is not flexible enough? I don't fully understand the use case yet
