### [Django REST Framework](https://www.django-rest-framework.org/) { #django-rest-framework }

Django REST framework 的目標是成為一套在 Django 之上構建 Web API 的彈性工具組，以強化其 API 能力。

它被 Mozilla、Red Hat、Eventbrite 等眾多公司使用。

它是「自動 API 文件」的早期典範之一，而這正是啟發我「尋找」**FastAPI** 的第一個想法。

/// note

Django REST Framework 由 Tom Christie 創建。他同時也是 Starlette 與 Uvicorn 的作者，而 **FastAPI** 就是建立在它們之上。

### [Django REST Framework](https://www.django-rest-framework.org/) { #django-rest-framework }

Django REST framework was created to be a flexible toolkit for building Web APIs using Django underneath, to improve its API capabilities.
