Django Ninja - Fast Django REST Framework

Django Ninja is a web framework for building APIs with Django and Python 3.6+ type hints.

Key features:

  • Easy: Designed to be easy to use and intuitive.
  • FAST execution: Very high performance thanks to Pydantic and async support.
  • Fast to code: Type hints and automatic docs lets you focus only on business logic.
  • Standards-based: Based on the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema.
  • Django friendly: (obviously) has good integration with the Django core and ORM.
  • Production ready: Used by multiple companies on live projects (If you use django-ninja and would like to publish your feedback, please email ppr.vitaly@gmail.com).

Installation

pip install django-ninja

Usage

In your django project next to urls.py create new api.py file:

from ninja import NinjaAPI

api = NinjaAPI()


@api.get("/add")
def add(request, a: int, b: int):
    return {"result": a + b}

Now go to urls.py and add the following:

...
from .api import api

urlpatterns = [
    path("admin/", admin.site.urls),
    path("api/", api.urls),  # <---------- !
]

That's it !

Now you've just created an API that:

  • receives an HTTP GET request at /api/add
  • takes, validates and type-casts GET parameters a and b
  • decodes the result to JSON
  • generates an OpenAPI schema for defined operation

Interactive API docs

Now go to http://127.0.0.1:8000/api/docs

You will see the automatic interactive API documentation (provided by Swagger UI or Redoc):
