Django REST Framework

Django REST Framework (DRF) is a Python library for building REST APIs on top of Django. It provides high-level abstractions: serializers (validate and convert data), viewsets (automatic CRUD endpoints), permissions (control who can access what), throttling (rate-limit requests), pagination, and authentication. A typical DRF flow: HTTP POST /users/ with JSON data → serializer validates → view saves to database → serializer returns JSON response. All with minimal boilerplate.
