Project Organization
It is crucial to split the application into smaller projects to achieve better organization and separation of concerns. This approach also enables better modularity, easier maintenance, and shared logic between different projects.
- Benefits of smaller projects
- Utilization of folders and onion architecture
Service Configuration
Clean service registrations are crucial for easy readability and maintenance. Using extension methods to move service registration logic from the program class ensures clean configuration and readability.
- Benefits of clean service registrations
- Usage of extension methods for registrations
Controller and Actions
Controllers should remain clean, without embedded business logic, and be responsible for accepting service instances and organizing HTTP action methods. Clean and simple responsibilities include handling HTTP requests, model validation, error handling, and returning responses.
Quote:
"Controllers should be clean and simple, with responsibilities limited to handling HTTP action methods."
Exception Handling
Global exception handling is essential for maintaining clean controller actions. By implementing exception handling globally, the logic is extracted into different features, promoting clean and readable action methods.
- Benefits of global exception handling
- Utilization of action filters to extract logic
DTO Usage
Utilizing DTOs for returning results and accepting inputs helps to build better APIs. Separating entities for communication with the client from entities communicating with the database is a best practice.
- Benefits of using DTOs
- Prevention of circular reference problems
Routing
Attribute routing is recommended over conventional routing for better descriptive routes, matching route parameter names with actual parameters inside action methods.
- Advantages of attribute routing
- Descriptive route examples
Quote:
"Attribute routing provides descriptive routes, ensuring clarity for API consumers."
Logging
Implementing a logging mechanism is essential for monitoring software behavior in production. Various logging providers can be used to implement logging logic within a project.
- Importance of logging in production
- Utilization of NLog library for custom logging
Paging, Searching, and Sorting
Implementing paging, searching, and sorting in API development is crucial for optimizing performance and better navigation of returned results.
- Advantages of implementing paging, searching, and sorting
- Utilization of the Builder pattern for chaining calls
List:
- Benefits of implementing paging, searching, and sorting
- Utilization of the Builder pattern for optimization
API Versioning
API versioning is recommended to support changing requirements without impacting API consumers, preserving the old functionality and promoting new features.
- Importance of API versioning
- Benefits of supporting changing requirements
Asynchronous Code
Usage of asynchronous code is crucial for avoiding performance bottlenecks and enhancing application responsiveness. Asynchronous code improves scalability and prevents thread pool blocking.
- Advantages of asynchronous code
- Utilization of asynchronous code for database operations
Caching
Implementing caching is recommended to boost application performance, reduce database costs, and improve data retrieval processes.
- Benefits of caching
- Importance of reducing database access
Quote:
"Caching significantly improves application performance and reduces database costs."
Content Negotiation
Implementing content negotiation for formatting API responses based on client requests is crucial for supporting various response formats.
- Importance of content negotiation
- Custom format rules and configuration
Security
Implementing JWT authentication and authorization systems, along with refresh tokens, is essential for secure app development and ensuring a better user experience.
- Importance of JWT authentication
- Benefits of using external token providers
Conclusion
By following the best practices discussed in the video, developers can create outstanding APIs. Sharing additional thoughts and practices in the comment section is encouraged for the benefit of the developer community.
