Motivation
Redux for mobile is relatively new architecture, basically starting in 2016. It was borrowed from the web where it has a huge adoption. There have been many libraries published for Android & iOS, but the ecosystem has not grown like it has for the web.
ReduxKotlin.org aims to create a standard Redux for Kotlin apps that can be used for Android or sharing code between Android, iOS, web.
Redux as a pattern for sharing code between platforms looks promising, especially in the future with Jetpack Compose and SwiftUI. For an example of shared code in a SwiftUI app look at the MovieSwiftUI-Kotlin example.
