2022 Hit Refresh! Praxis now loves ❤️ Jetpack Compose

This is a sample app written in Kotlin following clean architecture principles which uses slack app features as an example.

The purpose of this app to showcase:

• Implementation of Jetpack Android Architecture components with Dagger Hilt and Data Binding to minimize boilerplate code.
• Implementation of an architecture that will support both XML and the new Compose.

Presentation Layer contains UI (Activities & Fragments) that are coordinated by ViewModels which execute 1 or multiple UseCases. Presentation Layer depends on Domain Layer.

Domain Layer is the most INNER part of the circle (no dependencies with other layers) and it contains Entities, Use cases & Repository Interfaces. Use cases combine data from 1 or multiple Repository Interfaces.

Data Layer contains Repository Implementations and 1 or multiple Data Sources. Repositories are responsible to coordinate data from the different Data Sources. Data Layer depends on Domain Layer.

Notes: Mapping between response models and transformed models will happen via extension functions defined in transformed model file

Files are suffixed with be defined Class types.

• ViewModels are suffixed with VM. Ex: LoginVM
• UseCases are suffixed with UseCase. Ex: LoginUseCase
• Sources are suffixed with Source. Ex: LoginRemoteSource, LoginLocalSource
• Repositories are suffixed with Repo. Ex: LoginRepo

This project can be used as a template for new apps. This project is continually evolving to integrate other libraries and techniques to keep it up to date.
