jsonabler

Python package for making your classes easy encodable to JSON string and vice-versa.

Getting started

Requirements

• Python >= 3.8

Installation

pip install jsonabler

Usage

Making a Jsonable

Make your class extends the Jsonable interface and implements get_jsonable_data and from_jsonable_data methods with the encoding/decoding logic.

from jsonabler import Jsonable, jsonabled 

@jsonabled
class Foo(Jsonable):
    def __init__(self, bar: str):
        self.__bar = bar
    
    def get_jsonable_data(self) -> dict:
        return {
            'bar': self.__bar,
        }

    @classmethod
    def from_jsonable_data(cls, data: dict) -> Jsonable:
        return cls(data['bar'])

Registering a Jsonable

For decoding your Jsonable classes, you need to register it.

Decorating your classes with the @jsonabled decorator

from jsonabler import Jsonable, jsonabled 

@jsonabled
class Foo(Jsonable):
    ...

Calling register_jsonables method passing class types

from jsonabler import Jsonable, register_jsonables 

class Foo(Jsonable):
    ...

if __name__ == '__main__':
    register_jsonables({Foo})

Encoding a Jsonable

Call dumps method passing a Jsonable object.

from jsonabler import dumps

def upload_foo(foo: Foo) -> None:    
    json_string = dumps(foo)
    
    # transmit your JSON string
    ...

Encoded Foo

[
  'Foo',
  {
    'bar': "abc",
  }
]

Decoding a Jsonable

Call loads method passing the JSON string.

from jsonabler import loads, JsonableDecodeError, JsonableNotRegisteredError
from json import JSONDecodeError

def download_foo() -> Foo:    
    # receive JSON string encoded Foo object
    ...

    try:
        return loads(json_string)
    
    # not a valid encoded JSON string
    except JSONDecodeError:  
        ...
    
    # the Jsonable type of the encoded object was not registered
    except JsonableNotRegisteredError:  
        ...
    
    # something went wrong while decoding the object
    except JsonableDecodeError:  
        ...
