Design Principles in Clean Architecture
Clean Architecture adheres to several design principles that guide the structuring of software systems to promote maintainability, scalability, and testability. Here are the key design principles in Clean Architecture:
- Single Responsibility Principle (SRP)
- Every class should have only one reason to change, which means that a class should have only one responsibility or its functionality should be limited to just one task.
- This makes the class easier to comprehend, evaluate, and build as compared to other programming structures that may be more complex to handle.
- It minimizes the level of code which enhances clarity, and it enhances the maintainability of the source code.
- This reduces the exposure of the system to bugs that cause changes because only fewer classes are affected.
- Open-Closed Principle (OCP)
- Organizations and systems should be designed to be easily extensible but on the other hand, the existing interfaces should not be alterable or modifiable easily.
- One circuit that is unique with modules is that the action of a module can be further mannered without a direct signal to its source program.
- This is mainly done through the process of abstraction and polymorphism. It promotes flexibility and eliminates the possibility of having bugs creeping in as developers add new features.
- Liskov Substitution Principle (LSP)
- Subtypes must be able to substitute their base types and thereby not affect the integrity of the program in the process.
- Generated classes should degrade gracefully while adding functionality to the base class and not alter its behavior.
- It guarantees that you can freely use a derived class instead of the base class thereby improving reliability and robustness.
- Interface Segregation Principle (ISP)
- If one can offer a mechanism where clients are not dependent on interfaces they do not utilize, it should be encouraged.
- Somewhere these smaller specialized interfaces are preferred over having one larger general purpose interface.
- This means that clients use only those methods they need, to help them achieve their goals. Flux also helps minimize the effects of changes and increase flexibility.
- Dependency Inversion Principle (DIP)
- High levels of modules should not be dependent on low levels of modules. Both should follow abstractions (e.g., interfaces).
- One of the popular principles that has been widely used in object-oriented programming is the Dependency Inversion Principle which states that abstractions should not depend on details but rather details should depend on abstractions.
- This principle is in charge of limiting the dependency between two distinct parties or instead between a superior and inferior module, by presenting an abstraction.
- This increases modularity as the system achieves flexibility and can easily be modified to suit change.
Complete Guide to Clean Architecture
Clean Architecture is a software design approach that promotes the separation of concerns, ensuring systems are maintainable, scalable, and testable. By organizing code into distinct layers, each with a clear responsibility, Clean Architecture allows developers to build robust, flexible applications. This guide provides a comprehensive overview of Clean Architecture principles, illustrating how to structure your codebase for optimal performance and ease of maintenance.
