Know the Boundaries
KMP shares a lot, but not everything. Knowing the real boundaries keeps your expectations honest on a production team. 🧱
Share: Business Logic
Pure rules and calculations share beautifully. Your business logic has no platform ties, so it runs the same everywhere.
Share: Data Models
Your data models, the classes that describe a user or an order, are easy wins. Define them once and use them on every target.
data class User(
val id: String,
val name: String
)Share: Networking
HTTP calls and JSON parsing share well using multiplatform libraries. Your whole networking layer can live in shared code.
Share: Local Storage
Databases and key-value stores have multiplatform options too. So your storage layer is also a strong candidate for sharing.
Often Native: The UI
Most teams keep the UI native for the best feel. You can share it with Compose Multiplatform, but it stays a real choice.
Native: Platform Features
Camera, sensors, and OS dialogs differ per platform. These platform features need native code, often behind a shared interface.
The expect/actual Bridge
For things that differ per platform, KMP offers expect/actual. You declare a common API and give each platform its own version.
expect fun platformName(): StringSome Libraries Are JVM-Only
Not every Kotlin library is multiplatform. JVM-only libraries cannot go in common code, so check support before adding one.
A Healthy Default
A common starting line: share logic, data, and networking; keep UI native. Adjust the split as your team gains confidence.
It Keeps Improving
The KMP ecosystem grows fast, so what is shareable keeps expanding. More libraries go multiplatform every year.
Quick Check
Let's test the sharing boundaries.
Recap
Share logic, models, networking, and storage freely; keep UI and device features native. Use expect/actual to bridge the gaps. 🎉
