elmo :: elm architecture for android

Elmo is the Android framework from Badge that I use for nearly all product development at Badge. When I began creating Elmo, my goal was not to create yet another architecture pattern like MVP, MVC,MVVM, it was to allow even a single person to deliver a large scale application easier, faster, and to have fun in the process.

Elmo will help you write your android applications in a modern, unidirectional and functional way. You will have easy and great tests for free, and you will never have to deal with concurrency and async issues.

I am a firm believer in functional programming, and I know that for many Android developers this is still uncharted territory, but if you keep reading until the end, I promise you that you will rise again, harder and stronger! For what is immutable my never change!

Elmo is Kotlin first and Kotlin only. If you are not familiar with Kotlin, in particular, data and sealed classes, please run through Kotlin Koans or other Kotlin tutorials before continuing with Elmo.

Elmo is built on top of the following existing technologies and concepts:

• Kotlin
• RxJava
• Elm ( conceptually )
• Redux (conceptually)
• Jetpack Compose ( optional but recommended)
• Epoxy (optional but recommended)
