# 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 **<a href="https://pydantic-docs.helpmanual.io" target="_blank">Pydantic</a>** and **<a href="/docs/docs/guides/async-support.md">async support</a>**.
 - **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:

```Python
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:

```Python hl_lines="3 7"
...
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 <a href="http://127.0.0.1:8000/api/docs" target="_blank">http://127.0.0.1:8000/api/docs</a>

You will see the automatic interactive API documentation (provided by <a href="https://github.com/swagger-api/swagger-ui" target="_blank">Swagger UI</a> or <a href="https://github.com/Redocly/redoc" target="_blank">Redoc</a>):
