Sample code of React with Clean architecture

This project is a small idea sample code to introduce a Clean Architecture to a web service or to use a Redux Architecture and a Clean Architecture together.

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

Clean Architecture

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..

Communitaction Flow

in simple diagram, it is as above.

Session

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 'Storege' in 'Infrastructures'. this is part of a detailed implementation that can change, and is positioned according to its role to improve maintenance.

Board

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 'Action' with Entity data.
In 'View', the Action value is dispatched according to the flow of Redux architecture, and the Dispatcher updates the Store value to notify that it is changed. In View, the 'Entity' value of the Store is re-encapsulated as 'View Model' and is based on the 'View Model' value. Draw a view.

Inversion of Control

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 Action Interface of 'Presenter' is also the same.

• The basic directory is organized based on layers of clean architecture.
  [ frameworks / adapters / domains(useCases / entities) ]
• The component's directory structure is freely structured in the form promised between services or members.
