json_typer

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

Installation

pip install json_typer

Usage

Making a class type serializable

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

Exporting a type serializable class

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": ""
}

Importing a JSON file

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

Running Tests

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

Limitations

• 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
