What does HackerNews think of mashumaro?
Fast and well tested serialization library on top of dataclasses
Language:
Python
Yes, there are many tools for converting dataclasses to dict, json or something else, mashumaro (https://github.com/Fatal1ty/mashumaro) is one of them.
Having run into these issues with Pydantic, we've been using Mashumaro[1], which, while not having all the bells and whistles of Pydantic, has served us pretty well.
Also related to that I just came across a library that can generate json schema from a dataclass https://github.com/s-knibbs/dataclasses-jsonschema
There's also https://github.com/Fatal1ty/mashumaro for json serialization.
