ASP.NET Minimal API

Pros

  • Minimal Hosting Model
    • Enables the creation of a single, clean entry point for the API.
  • Development Speed
    • No need for controllers or boilerplate code (though you can still organize mapped methods into files). A single method with fluent API extensions is sufficient.
  • Simplicity
    • Reduces the complexity of creating APIs.
  • Performance
    • With fewer layers of abstraction, it performs better compared to controller-based approaches.
  • Flexibility
    • Easily extend functionality for specific endpoints or endpoint groups by adding new extension methods.
  • Lightweight by Design
    • Minimal APIs have a smaller memory footprint, making them ideal for serverless environments or resource-constrained systems.
  • Built-in Support for OpenAPI/Swagger
    • Minimal APIs include built-in support for generating OpenAPI/Swagger documentation without requiring additional configuration or significant effort.

Cons

  • Maintenance and Readability
    • As the project grows, maintaining endpoints can become challenging.
  • Missing Funcionality
    • Compared to the classic controller-based approach, some features may be lacking. However, maintainers often introduce updates for Minimal APIs with every new release.
  • Learning Curve for Beginners
    • Developers coming from the traditional controller-based mindset might find the concept of organizing endpoints in Minimal APIs less intuitive initially.
