@lucca65 looks good but missing unit tests for regression coverage, I also moved the inputs to input objects to make it easier to use and uniform

Hey @zacck I'll do the tests.

Can you explain to me why is the input objects important? For me they only make the query more complex and I can't see any benefits for using it. For filters or more complex inputs it is completely fine, but even in the GraphQL project home page they don't use it:

@lucca65 I wouldn't expect them to show them in the Graphql homepage since, it adds to the learning curve. In any case input objects introduce ease of auto generation of code as we do with the elm-graphql library and as we go along and as our inputs grow its easier to modify an input object rather than building up complex arguments.

It's one of those things I have picked up working with multiple graphql APIs let me know if I can send you more texts to justify if you need ...
