    Workflow

    Workflow

    A Swift and Kotlin library for making composable state machines

    Workflow is an application framework that provides architectural primitives. A corresponding testing framework that facilitates simple-to-write unit tests for all application business logic and helps ensure correctness. Corresponding UI frameworks that bind Rendering data classes for “views” (including event callbacks) to Mobile UI frameworks for Android and iOS. Optimized for composability and scalability of features and screens. A library that supports writing business logic and complex UI navigation logic as state machines, thereby enabling confident reasoning about the state and validation of correctness. A unidirectional data flow library that uses immutable data within each Workflow. Data flows in a single direction from the source to the UI, and events in a single direction from the UI to the business logic. Each logical component area is separated into a Workflow with a finite set of states and the logic to transition between them.

    Mavericks

    Mavericks

    Mavericks, Android on Autopilot

    Mavericks is an Android MVI framework that is both easy to learn yet powerful enough for the most complex flows at Airbnb, Tonal, and other large apps. When we began creating Mavericks, our goal was to make building products easier, faster, and more fun. We believe that for Mavericks to be successful, it must be easy to learn for people new to Android development working their first apps yet powerful enough to support the most complex screens at Airbnb. Mavericks is used in hundreds of screens at Airbnb including 100% of new screens. It has also been adopted by countless other apps from small sample apps to apps with over 1 billion downloads. Mavericks is built on top of Android Jetpack and Kotlin Coroutines so it can be thought of as a complement rather than a departure from Google's standard set of libraries. We believe that for Mavericks to be successful, it must be effective for building everything from the simplest of screens to the most complex in our app.
