Mixins are a concept in object-oriented programming where a class can include the properties and methods of another class without extending it. Essentially, it's a way to add functionality to a class from multiple sources.
Especially working with modern JavaScript or TypeScript, you might encounter mixins in legacy code or specific libraries but will likely use more contemporary patterns for code reuse and composition.
Recently, we had an in-depth discussion on structuring React applications using a layered architectural approach. This method aligns with fundamental software architecture principles such as the Single Responsibility Principle (SRP) and the Single Source of Truth (SSoT). It shares similarities with Clean Architecture and Layered Architecture and, interestingly, shows parallels with the Model-View-Controller (MVC) pattern in some respects. We are also applying Dependency Inversion principle (DIP), depending on abstractions rather than concrete implementations of lower-level modules.
The Dependency Inversion Principle (DIP) is one of the five SOLID principles, and it plays an essential role in achieving maintainable and flexible code. It can be applied to frontend development, particularly when using technologies like React and Redux.
