pyserde
Yet another serialization library on top of dataclasses, inspired by serde-rs.
Guide🇬🇧 | ガイド🇯🇵 | API Reference | Examples
Overview
pyserde is a simple yet powerful serialization library on top of dataclasses. It allows you to convert Python objects to and from JSON, YAML, and other formats easily and efficiently.
Declare your class with @serde decorator and annotate fields using PEP484 as below.
@serde
class Foo:
i: int
s: str
f: float
b: bool
You can serialize Foo object into JSON.
>>> to_json(Foo(i=10, s='foo', f=100.0, b=True))
'{"i":10,"s":"foo","f":100.0,"b":true}'
You can deserialize JSON into Foo object.
>>> from_json(Foo, '{"i": 10, "s": "foo", "f": 100.0, "b": true}')
Foo(i=10, s='foo', f=100.0, b=True)
That's it! If you're interested in pyserde, please check our documentation! Happy coding with pyserde! 🚀
