I wrote a small lib to convert malli schema object -> lacinia schema objects, which I thought others might find useful https://github.com/p14n/malli-lacinia
This could be reused into malli generator which will be the dummy resolver. Nice work
Great idea - tests added https://github.com/p14n/malli-lacinia/blob/main/test/p14n/malli_lacinia/gen_test.clj
Great! And this is a tragedy for client developers who could sit back and wait for the schema.
BTW, this is neither schema-first nor code-first approach. Maybe you invented data-first approach.
