databind.json 0.12.0

Bind object-oriented data models to JSON data.

databind.json

Databind is a library inspired by Jackson-databind to describe and bind data models for object-oriented programming. The databind.json package provides converters for JSON data types, data models and union types to serialize and deserialize JSON payloads.

Quickstart

from typing import Optional
from databind.core import datamodel
from databind.json import from_json

@datamodel
class Geolocation:
  latitude: float
  longitude: float
  altitude: Optional[float] = None

@datamodel
class ResolvedLocation:
  query: str
  location: Geolocation

london = from_json(ResolvedLocation, {
  "query": "London",
  "location": {
    "latitude": 51.507351,
    "longitude": -0.127758,
  },
})

assert london == ResolvedLocation("London", Geolocation(51.507351, -0.127758))
