 _/ | JSON SERIALIZATION
|__/      MADE EASY!

~ Any Python objects to/from JSON, easily! ~

  • Python 3.5+
  • Minimal effort to use!
  • No magic, just you, Python and jsons!
  • Human readible JSON without pollution!
  • Easily customizable and extendable!
  • Type hints for the win!

Example of a model to be serialized:

@dataclass
class Person:
    name: str
    birthday: datetime

Example of the serialization:

jsons.dump(Person('Guido van Rossum', birthday_guido))

Output after serialization:

{'birthday': '1956-01-31T12:00:00Z', 'name': 'Guido van Rossum'}

Installation

pip install jsons

Usage

import jsons

some_instance = jsons.load(some_dict, SomeClass)  # Deserialization
some_dict = jsons.dump(some_instance)  # Serialization

In some cases, you have instances that contain other instances that need (de)serialization, for instance with lists or dicts. You can use the typing classes for this as is demonstrated below.

from typing import List, Tuple
import jsons

# For more complex deserialization with generic types, use the typing module
list_of_tuples = jsons.load(some_dict, List[Tuple[AClass, AnotherClass]])

(For more examples, see the FAQ)
