KMP Toolkit

A collection of production-ready Kotlin Multiplatform libraries — one dependency per feature, works out of the box on every platform.

📖 Full usage docs: Docs site · Wiki · 🚀 Releases · 📦 Maven Central

The Docs site ships an API reference for every module via Dokka HTML bundled inside each Maven Central -javadoc.jar artifact — IntelliJ / Android Studio surface it automatically in hover popups.

Installation

All modules ship together at the unified kmptoolkit version. Declare it once in your version catalog, then add only the libraries you need:

# gradle/libs.versions.toml
[versions]
kmptoolkit = "LATEST"  # see Maven Central badge in the Modules table above

[libraries]
cmp-clipboard       = { module = "io.github.mobilebytelabs:cmp-clipboard",       version.ref = "kmptoolkit" }
cmp-bubble          = { module = "io.github.mobilebytelabs:cmp-bubble",          version.ref = "kmptoolkit" }
cmp-toast           = { module = "io.github.mobilebytelabs:cmp-toast",           version.ref = "kmptoolkit" }
cmp-open-url        = { module = "io.github.mobilebytelabs:cmp-open-url",        version.ref = "kmptoolkit" }
cmp-deep-link       = { module = "io.github.mobilebytelabs:cmp-deep-link",       version.ref = "kmptoolkit" }
cmp-in-app-update   = { module = "io.github.mobilebytelabs:cmp-in-app-update",   version.ref = "kmptoolkit" }
cmp-remote-config   = { module = "io.github.mobilebytelabs:cmp-remote-config",   version.ref = "kmptoolkit" }
cmp-product-tickets = { module = "io.github.mobilebytelabs:cmp-product-tickets", version.ref = "kmptoolkit" }
cmp-network-monitor = { module = "io.github.mobilebytelabs:cmp-network-monitor", version.ref = "kmptoolkit" }
cmp-pdf-generator   = { module = "io.github.mobilebytelabs:cmp-pdf-generator",   version.ref = "kmptoolkit" }
cmp-firebase-analytics = { module = "io.github.mobilebytelabs:cmp-firebase-analytics", version.ref = "kmptoolkit" }
cmp-share           = { module = "io.github.mobilebytelabs:cmp-share",           version.ref = "kmptoolkit" }
cmp-intent-launcher = { module = "io.github.mobilebytelabs:cmp-intent-launcher", version.ref = "kmptoolkit" }
cmp-app-intents     = { module = "io.github.mobilebytelabs:cmp-app-intents",     version.ref = "kmptoolkit" }
# Compose adapter modules (optional)
cmp-share-compose            = { module = "io.github.mobilebytelabs:cmp-share-compose",            version.ref = "kmptoolkit" }
cmp-intent-launcher-compose  = { module = "io.github.mobilebytelabs:cmp-intent-launcher-compose",  version.ref = "kmptoolkit" }
cmp-app-intents-compose      = { module = "io.github.mobilebytelabs:cmp-app-intents-compose",      version.ref = "kmptoolkit" }
cmp-network-monitor-compose  = { module = "io.github.mobilebytelabs:cmp-network-monitor-compose",  version.ref = "kmptoolkit" }

Then reference any library from commonMain via the standard implementation(libs.cmp.<name>) pattern.

💡 Replace LATEST with the version shown in the Maven Central badge at the top of this README — single source of truth, single line to bump when a new release ships.

Platform Support

The toolkit targets every platform Kotlin Multiplatform supports. Per-module coverage varies — see each module's Wiki page for the authoritative matrix. Quick reference:

Platform	Targets	Modules with full coverage
Android	androidTarget	All
iOS	iosX64, iosArm64, iosSimulatorArm64	All
macOS	macosX64, macosArm64	All except bubble, product-tickets
JVM Desktop	jvm	All
JS	js (browser + node)	All except bubble, toast, in-app-update, product-tickets
wasmJs	wasmJs (browser + node)	All except bubble, toast, in-app-update, product-tickets
Linux	linuxX64, linuxArm64	clipboard, open-url, deep-link, in-app-update, remote-config, network-monitor, share, intent-launcher, app-intents
Windows	mingwX64	Same as Linux
tvOS / watchOS	tvosX64/Arm64/SimulatorArm64, watchosX64/Arm32/Arm64/SimulatorArm64/DeviceArm64	network-monitor, share (limited), app-intents (manifest-only)

Inter-App Comms Suite

Three modules ship together as the inter-app communication suite — all share the same Compose-MP adapter pattern (core + -compose adapter):

• cmp-share + cmp-share-compose — share sheets via OS-native dispatch
• cmp-intent-launcher + cmp-intent-launcher-compose — typed Intent builder + lifecycle-free SystemIntents (settings + save dialog) + Composable launchers
• cmp-app-intents + cmp-app-intents-compose — declarative App Intents DSL (SiriKit + Assistant BIIs)

Architecture docs: docs/inter-app-comms/CAPABILITY_MATRIX.md · ADR-09 (platform-impl-exits)

Sample App

sample-toolkit is the unified catalog app — every published cmp-* module wired in one Compose Multiplatform project. Pick a module from the catalog UI to launch its dedicated showcase. Same app, every platform:

# Desktop (JVM)
./gradlew :samples:sample-toolkit:composeApp:run

# Android
./gradlew :samples:sample-toolkit:androidApp:installDebug

# Web (browser — JS + wasmJs)
./gradlew :samples:sample-toolkit:composeApp:jsBrowserDevelopmentRun
./gradlew :samples:sample-toolkit:composeApp:wasmJsBrowserDevelopmentRun

# iOS — open samples/sample-toolkit/iosApp in Xcode

Per-module standalone samples (one per library) live alongside sample-toolkit under samples/ — useful if you want to study a single module in isolation.

First-run note (web targets): jsBrowserDevelopmentRun / wasmJsBrowserDevelopmentRun downloads ~50MB of Skiko WASM assets on a cold cache. Subsequent runs are fast. If you hit OutOfMemoryError: GC overhead limit exceeded, ensure org.gradle.jvmargs=-Xmx4096M in gradle.properties (the repo default).

Contributing

New module template lives at cmp-library/ — copy + rename + add to settings.gradle.kts + ship a sample under samples/. Full walkthrough: Wiki › Adding New Features · CONTRIBUTING.md.
