Architecutre details

Apotheosis uses the MVVM (Model - View - View Model) architecture pattern, this separates the frontend into a couple layers.


- Insert graph here


As seen in the graph above, there is two primary layers that are used.

• First the UI layer, this layer is primarily for collecting input and showing data.
  • The UI layer takes data from a view model and displays it to the views, in Jetpack compose, this could be a Composable.
  • The UI layer also should send inputs to the view model for the view model to decide what to do with the input.
• Second is the data layer, this is where you store Models, or collecting backend data.
  • The data layer collects data through multiple sources, such as the Apotheosis API, or the local Room DB.
  • The data layer also uses the concept of Repositories, which are a way to further enhance separation of concerns. The view model comes into play as it can bridge the two layers together nicely, as it is the preferred method to holding business logic.

Apotheosis API

The Apotheosis API gives you a way to access our nutritional database and get your user data to use in any of your projects. When the Apotheosis API goes public you can check here on how to use it.
