v0.13.0

What's Changed

New features

New custom class (de)serializer allows to extend pyserde to support third party types in a neat and robust way. Also custom global (de)serializer is a game changer to allow sharing and reusing custom serializers across different python projects. See custom class serializer and custom global serializer for more information.

e.g. Implementing serializer for datetime and int

class Serializer:
    # Custom serializer for "datetime"
    @overload
    def serialize(self, value: datetime) -> str:
        return value.strftime("%d/%m/%y")

   # Custom serializer for "int"
   @overload
   def serialize(self, value: int) -> Any:
       return str(value)

v0.12.0

What's Changed

New features

• Union directly by @yukinarit in #339

This example works correctly now

@serde
@dataclass
class Foo:
    a: int

@serde
@dataclass
class Bar:
    a: int

bar = Bar(10)
s = to_json(bar)
print(s)
print(from_json(Union[Foo, Bar], s))

However, This will introduce a breaking change!! The default behaviour when you pass Union directly was "Untagged" until v0.11.1, but since v0.12.0 it is "ExternalTagging".

The following code prints {"a": 10} until v0.11.1, but prints {"Bar": {"a": 10}} since v0.12.0

print(to_json(bar))

For more information about Union, please see the docs
