Introduction

Django REST Framework (DRF) is a powerful and flexible toolkit for building Web APIs in Django.

Why use DRF?

• Web browsable API: A massive usability win for your developers.
• Serialization: Supports both ORM and non-ORM data sources.
• Customizable: Highly customizable, allowing you to use regular function-based views if you don't need the more powerful features.
• Community: Extensive documentation and great community support.

Core Components

Component	Purpose
Serializers	Convert complex data (like model instances) into native Python datatypes that can be easily rendered into JSON/XML, and vice versa.
Views / ViewSets	Handle the logic for answering requests and returning responses. DRF provides generic views to speed up common patterns.
Routers	Automatically generate URLs for your API by wiring up ViewSets.
Authentication & Permissions	Secure your API by identifying users and defining access control rules.
