feature: generate schema from class

I see that it is possible to use a json schema to validate against. Is it also possible to generate the schema from the class?

I am currently using simpl-schema which has a great ecosystem (e,g, auto generating forms) However, I want to move away from json based schemas towards a more modern approach (i.e. class-validator package), but now I would need to define everything twice (decorators & json schema). Generating the schema from decorators would prevent a lot of duplicate code.

I don’t really care about the syntax/structure of the generated json schema since I can just write a transformer to generate the simpl-schema syntax from it.

I also don’t mind contributing if you can point me into the right direction. I would need some way to get all validator types and their arguments:

schema = {}
properties.forEach(property => {
    property.validators.forEach(validator => {
            schema[property.name][validator.name] = validator.value
    })
})

is there any progress on this? it would be really nice to have this feature.
