Revisiting foundational design principles

Besides React-specific patterns, we’ve discussed several higher-level design principles throughout various chapters. These principles serve as guidelines applicable to various aspects of your work, be it React, data modeling, event testing, or scripts that facilitate integration. They are not confined to a particular context, and embracing them can significantly enhance your coding approach across different domains.

The SRP advocates that a class or component should only harbor one reason to change. Adhering to the SRP can lead to more maintainable and understandable code, mitigating issues such as big components and complicated logic in views.

We’ve explored this principle at various levels, from carving out a smaller component from a larger one, to creating a new Hook, and up to significant refactoring such as integrating an ACL into a weather application. It’s worth noting that...
