- •Course review and next steps
API Design
- •RESTful architecture follows specific principles
- •Resource-based URL design promotes clarity
- •HTTP methods map to CRUD operations
- •Well-designed APIs are intuitive and consistent
Security
- •Authentication and authorization are fundamental
- •JWT provides a stateless authentication mechanism
- •Input validation prevents many security issues
- •Security is a multi-layered approach
Performance
- •Database optimization is critical for scalability
- •Caching significantly improves response times
- •Asynchronous processing helps handle high loads
- •Monitoring helps identify bottlenecks
Best Practices
- •Follow consistent naming conventions
- •Document your API thoroughly
- •Test all endpoints and edge cases
- •Use proper error handling
- •Version your API from the start
