This guide encompasses best practices and recommended architecture for building robust, high-quality apps

• Guide to app architecture (Gooogle Developers)

• Read Medium about my article

This sample demonstrates how one can

• Setup base architecture of React Native app using Clean Architecture
• Use dependency injection for layers separation
• Make api calls using Axios plugin.

• Axios : http client
• Styled-components : styled-components
• Inversify : dependency injection

There are 3 main modules to help separate the code. They are Data, Domain, and Presentaion.

• Data contains Local Storage, APIs, Data objects (Request/Response object, DB objects), and the repository implementation.

• Domain contains UseCases, Domain Objects/Models, and Repository Interfaces

• Presentaion contains UI, View Objects, Widgets, etc. Can be split into separate modules itself if needed. For example, we could have a module called Device handling things like camera, location, etc.

• Using modular architecture to architect the app per feature to be easier and more readable and isolate the feature from each other

• Bridge between Data layer and Domain layer
• Connects to data sources and returns mapped data
• Data sources include DB and Api

• Responsible for connecting to repository to retrieve necessary data. returns a Stream that will emit each update.
• This is where the business logic takes place.
• Returns data downstream.
• Single use.
• Lives in Domain (No Platform dependencies. Very testable).

• Organizes data and holds View state.
• Talks to use cases.

• View,updates UI
