MVICore is a modern, Kotlin-based MVI framework:

• Scaling with complexity: operate with a single Reducer if needed, with the option of having the full power of additional components to handle more complex cases
• Event handling: A solution to handling events that you don’t want to store in the state
• Reactive component binding: A super simple API to bind your reactive endpoints to each other with automatic lifecycle handling
• Custom Middlewares: for every single component in the system, with flexible configuration options
• Logger: An out-of-the-box logger Middleware
• Time Travel Debugger: for ALL of your reactive components (not just your state machine!) with UI controls for recording and playback

The library comes with lots of powerful capabilities and tooling.

See https://badoo.github.io/MVICore/ for full documentation.

Available through jitpack.

Add the maven repo to your root build.gradle

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Add the dependencies:

• Framework:

implementation 'com.github.badoo.mvicore:mvicore:{latest-version}'

• Binder (for versions higher than 1.2.4)

implementation 'com.github.badoo.mvicore:binder:{latest-version}'

• Helper classes for Android:

implementation 'com.github.badoo.mvicore:mvicore-android:{latest-version}'

• ModelWatcher for efficient view updates

implementation 'com.github.badoo.mvicore:mvicore-diff:{latest-version}'

• Time Travel Debugger controls in a DebugDrawer module (You need to add the dependencies to DebugDrawer and configure it yourself before you can use this):

implementation 'com.github.badoo.mvicore:mvicore-debugdrawer:{latest-version}'

• MVI beyond state reducers
• Building a system of reactive components with Kotlin
• Unidirectional data-flow and the Zen of black box components
