Thanks @msimulcik ! Could you add some tests to make sure the code actually works and we don't regress?

[msimulcik]

Sure. Would it be enough to cover only the case when I call mutation and expect updateQueries and reducer on query with union type to be called? I'm thinking about adding it to test/client.ts

[helfer]

@msimulcik yes, I think that would be enough for now. I can add any other test cases if necessary 🙂

[helfer]

@msimulcik Actually, let me merge this and release a patch version. Would be great if you could add the test in a separate PR though.

I'm on it now. I had to go to sleep yesterday :)
