toonio is a package for sending data in the Toon format, which is several times faster than JSON.

This library also supports integration with Django views and provides compatibility for use in FastAPI as well.

The library offers two important features for Django. For example, you can create dynamic views that can return either JSON or Toon based on the request.

toonio — Django Integration Guide

Usage

pip install "toonio[django]"

Return Toon for all requests

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': [
        'toonio.django.render.ToonRenderer',
    ],
    'DEFAULT_PARSER_CLASSES': [
        'toonio.django.parser.ToonParser',
    ],
}

Enable dynamic mode (JSON or Toon based on headers)

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': [
         'toonio.django.render.DynamicRenderer',
    ],
    'DEFAULT_PARSER_CLASSES': [
        'toonio.django.parser.DynamicParser',
    ],
}

Header Examples

Send JSON → Receive Toon:

Content-Type: application/json
Accept: application/x-toon

Send Toon → Receive Toon:

Content-Type: application/x-toon
Accept: application/x-toon

Send Toon → Receive JSON:

Content-Type: application/x-toon
Accept: application/json

Per-View Configuration

Dynamic view

from toonio.django.parser import DynamicParser
from toonio.django.render import DynamicRenderer

class Index(APIView):
    parser_classes = [DynamicParser]
    renderer_classes = [DynamicRenderer]

    def get(self, request, *args, **kwargs):
        return Response({"message": "Hello Toon"})

Toon-only view

from toonio.django.parser import ToonParser
from toonio.django.render import ToonRenderer

class Index(APIView):
    parser_classes = [ToonParser]
    renderer_classes = [ToonRenderer]

    def get(self, request, *args, **kwargs):
        return Response({"message": "Hello Toon"})

Usage in FastApi:

pip install "toonio[standard]"

from fastapi import FastAPI

from toonio.response import Response
from toonio.status import HTTP_200_OK

app = FastAPI()


@app.get("/")
def hello_toon():
    return Response({"Hello": "Toon"}, status_code=HTTP_200_OK) # Return Toon Response
