jstruct 2021.11

Readable serializable and deserializable Python nested models

jstruct

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

Why

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

How

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

What

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

Requirements

• Python 3.6 and +

Installation

Install using pip

pip install jstruct

Usage

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

@struct
class Person:
    first_name: str
    last_name: str

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


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

role_models = RoleModels(**payload)

print(role_models)

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

print(attr.asdict(role_models))

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