This project is a sample code of one small idea to introduce a clean architecture to web services in a large sense, and a clean architecture to a project using React in a small sense. With minimal library and service functions, we are concentrating on overall project composition.

if you leave an issue or a pull request, we will reflect the insufficient part or improvement. ☺️

As with various architectures, the primary purpose of a clean architecture is to separate concerns. Divide the hierarchy according to each interest, design domain-centric rather than detailed implementation, and make sure that the internal area does not depend on external elements such as the framework or database UI.

• Distinguish between detailed implementation areas and domain areas.
• Architecture does not depend on the framework.
• The outer zone can depend on the inner zone, but the inner zone cannot depend on the outer zone.
• Both high-level and low-level modules rely on abstraction..

The monorepo package consists of the above. The domain area, adapter area, and framework area are each configured as a package and designed to be more clearly distinguished. New services can be configured by adding packages from the framework area.

in simple diagram, it is as above.

After the user logs in, the issued authentication token is stored and used in the web storage. web storage is accessible globally, but the sample code follows the flow above and is controlled by 'Storage' in 'Infrastructures'. this is part of a detailed implementation that can change, and is positioned according to its role to improve maintenance.

Board posts and comments are fetched through http communication from 'Infrastructures', encapsulated as Board Root Entity including Comment Entity in 'Use Case' and delivered to 'Presenter', and 'Presenter' returns Entity data.
in 'Components', 'Entity' data or 'View Model' encapsulated data is stored in the state management manager, and the view is redrawn according to the state change of the data.

In the case of 'Repository', it is an adapter layer, so you should not know about 'Repository' in 'Use Case'. Therefore, in 'Use Case', it is implemented through the Repository Interface located in the domain layer, which is then operated through Dependency Injection.

• The package structure of the monorepo is based on the layers of the clean architecture.
  [ adapter / domain(useCases/entities) / mobile(react-native) / web ]
• The component's directory structure is freely structured in the form promised between services or members.
