Readable serializable and deserializable Python nested models

Project description


An eloquent and opinionated python library for nested object models definition offering simple serialization and deserialization into python dictionaries.

JStruct Codacy Badge Code style: black License: MIT


The deserialization of JSON or yaml into python data types is a common practice useful in many ways.

  • Configuration file reading and writing
  • REST API message response generation and request processing
  • Object-Document Mapping for a document store
  • Data import parsing or export generation


JStruct leverage attrs the great Classes without boilerplate library to define structs without boilerplate.


The result is a simple and intuitive syntax familiar to a pythonista that brings Validation, Deserialization and Serialization.


  • Python 3.6 and +


Install using pip

pip install jstruct


import attr
from typing import List
from jstruct import struct, JList

class Person:
    first_name: str
    last_name: str

class RoleModels:
    scientists: List[Person] = JList[Person]

payload = {
    "scientists": [{"first_name": "John", "last_name": "Doe"}] 

role_models = RoleModels(**payload)


# RoleModels(scientists=[Person(first_name='John', last_name='Doe')])


# {'scientists': [{'first_name': 'John', 'last_name': 'Doe'}]}
