This project is an example of a modular application to retrieve data from an external API (https://dummyapi.io).

It makes use of the following libraries:

• Jetpack Compose for the UI
• OkHttp / Retrofit for the REST requests
• Koin for dependency injection
• Room for database
• Coil for image retrieval
• Mockito Kotlin for some parts of unit testing

To build, you must add an application id for Dummy API in your local.properties file:

api_key=1234567890abcdef12345678

See https://dummyapi.io to generate your own key.

The DatasourceRepository interface is used to provide data to the application and have multiple implementations:

• datasource-server to retrieve data from a remote REST service
• datasource-room to retrieve and store data into a local Room database, by implementing MutableDatasourceRepository
• datasource-cached is a proxy implementation that retrieve data from another DatasourceRepository implementation and use a MutableDatasourceRepository implementation as cache

Two other implementations are used for testing purposes:

• datasource-test generate its own data and also provide some helper methods
• datasource-memory is an implementation of MutableDatasourceRepository which just store data in memory
