What is Decompose?

Decompose is a Kotlin Multiplatform lifecycle-aware business logic components (aka BLoCs) with routing functionality and pluggable UI (Android Views, Jetpack Compose, SwiftUI, JS React, etc.) This project is inspired by Badoos RIBs fork of the Uber RIBs framework.

Supported targets

  • android,
  • jvm
  • js (both IR and Legacy modes)
  • iosX64, iosArm64
  • tvosArm64, tvosX64
  • watchosArm32, watchosArm64, watchosX64
  • macosX64

Why Decompose?

  • Decompose draws clear boundaries between UI and non-UI code, which gives the following benefits:
    • Better separation of concerns
    • Pluggable platform-specific UI (Compose, SwiftUI, React, etc.)
    • Business logic code is testable with pure multiplatform unit tets
  • Proper dependency injection (DI) and inversion of control (IoC) via constructor
  • Shared navigation logic
  • Lifecycle-aware components
  • Components in the back stack are not destroyed, they continue working in background without UI
  • Components and UI state preservation (mostly useful in Android)
  • Instances retaining (aka ViewModels) over configuration changes (mostly useful in Android)
