4. Django REST Framework

Ganeshkumar Patil¹

Django REST Framework (DRF) is a powerful and flexible framework for building web APIs (Application Programming Interfaces) using Django, a popular Python web framework. DRF provides a set of tools and libraries that make it easier to build, test, and consume RESTful APIs in Django-based applications.

Some key features and components of Django REST Framework are as follows.

Serialization and Deserialization
