Seamlessly encode and decode python objects to json while maintaining their types.

pip install json_typer

To make a class type serializable (a.k.a to seamlessly serialize the class to JSON and then when loading the JSON convert the object to its old type) inherit from TypeSerializable and make sure you are passing *args, **kwargs to the super constructor.

from json_typer import TypeSerializable


class Foo(TypeSerializable):
    def __init__(bar, baz="", *args, **kwargs):
        self.bar = bar
        self.baz = baz

from json_typer import io

foo = Foo(bar="example")

io.exportJSON(path=EXAMPLE_FILE, data=foo)

EXAMPLE_FILE contents

{
    "type": "Foo"
    "module": "Foo"
    "bar": "example",
    "baz": ""
}

from json_typer import io


foo = io.loadJSON(path=EXAMPLE_FILE)

Access the loaded attributes like you normally would

foo.bar
>>> example

isinstance(foo, Foo)
>>> True

Open a terminal in this projects root directory and type python -m unittest

• Must have *args, **kwargs in the constructor and passed to the super call in any class that inherits from TypeSerializable
• A class that inherits from TypeSerializable cannot implement _type or _module attributes
