Clean architecture is a software design philosophy that aims to separate the elements of a design into ring levels, with the goal of providing developers with a way to organize code in such a way that it encapsulates the business logic but keeps it separate from the delivery mechanism. The main rule of clean architecture is that code dependencies can only move from the outer levels inward. Code on the inner layers can have no knowledge of functions on the outer layers. The variables, functions, and classes that exist in the outer layers cannot be mentioned in the more inward levels.
Clean architecture was created by Robert C. Martin and promoted on his blog, Uncle Bob. It attempts to provide a cost-effective methodology that makes it easier to develop quality code that will perform better, is easier to change, and has fewer bugs. The architecture is sustainable and loosely couples core business logic and entity with presentation layer or framework.
The primary idea in clean architecture is to make the solution adaptive, keep the core business or application logic use cases independent of frontend and external frameworks. The architecture is designed in such a way that it should be adaptive and flexible enough to handle the changing requirements of the software.
Advantages of clean architecture include that it is testable, maintainable, changeable, easy to develop, easy to deploy, and independent of frameworks. Clean architecture is a development philosophy that can help to develop and maintain long-lasting projects properly, but it is not a silver bullet to solve all the technical and design challenges.
