`0.8.1` (2022-06-14)

feat: Don't wrap user exception in SerdeError (161cffd)

`0.8.0` (2022-05-31)

Thanks to the contribution by @kigawas, pyserde can optionally use orjson as JSON serializer!

pip install pyserde[orjson]

If orjson is installed in the system, pyserde automatically use orjson in to_json/from_json.

NOTE: In order to align the JSON (de)serializer to orjson, a few parameters are passed in json.dumps internally. This would lead to a breaking change in some cases. If you need the same behaviour as in pyserde<0.8, please explicitely pass those parameters in serde.json.to_json. 🙇‍♂️

to_json(obj, ensure_ascii=True, separators=(", ", ": "))

Other noteble chage is we have @dataclass decorator back in the all example and test code in the repository as shown below. It's because we found mypy isn't able to deduce the type correctly without @dataclass decorator. If you are not mypy user, you can still declare a class with only @serde decorator. 👍 For more information, please read the docs.

@serde
@dataclass  # <-- Recommended to add @dataclass if you are mypy user.
class Foo:
    i: int
    s: str
    f: float
    b: bool

build: Add "orjson" extras (ea70ec1)
orjson support (2744675)
Update json.py (2d67b65)
feat: Support class declaration w/wo dataclass (a35f909)
