Building a Simple API

1. Create serializers for your models.
2. Define views using APIView, GenericAPIView, or ViewSet.
3. Register views in your urls.py.

Testing APIs

Use tools like:

• Postman: A GUI tool to test APIs.
• cURL: A command-line tool for making API requests.
• DRF Browsable API: DRF provides a browsable web interface for testing.

Consuming APIs

Clients (e.g., frontend apps) can use libraries like axios or fetch (JavaScript) or requests (Python) to consume APIs.

Example: Fetching API Data with JavaScript

fetch('https://example.com/api/posts/')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));
