Decompose is a Kotlin Multiplatform library for breaking code into tree-structured, lifecycle-aware business logic components (BLoCs) with routing/navigation and pluggable UI layers. It supports Jetpack/Multiplatform Compose, Android Views, SwiftUI, and Kotlin/React, keeping business logic testable and UI-agnostic.

Use cases

• share navigation and business logic across Android and iOS in Kotlin Multiplatform
• structure an app into lifecycle-aware BLoC components with parent-child trees
• swap UI frameworks (Compose, SwiftUI, React) while keeping the same logic
• keep back-stack components alive in background without UI
• preserve and restore component state across configuration changes
• write pure multiplatform unit tests for business logic

When to choose

• building a Kotlin Multiplatform app needing shared navigation and state
• you want strict separation of UI and business logic with pluggable UI
• you need lifecycle-aware components with state preservation and instance retention

When to avoid

• building a single-platform app where simpler platform-native navigation suffices
• you are not using Kotlin or Kotlin Multiplatform
• you want a batteries-included UI toolkit rather than a logic/navigation library
