dataclass_json is also very useful for schema validation. It combines python's native dataclass objects with marshmallow's schema to provide additional functionalities simply through a @dataclass_json decorator on your dataclass.

I made the similar dataclasses_serialization library. It doesn't require a special decorator on your classes, and is extensible for custom classes, and custom serialization methods (JSON and BSON provided by default).

I do something similar with dataclasses using the `dacite` (https://github.com/konradhalas/dacite) library as a constructor for python dicts to dataclasses with runtime type-checking.

Works really well with marshmallow for additional validation.
