KMP vs CMP
π οΈ Kotlin Multiplatform (KMP) β The Brains Behind the Scenes
Think of Kotlin Multiplatform like a magic Lego set that lets you reuse the same blocks to build things for Android, iOS, desktop, web, and even servers.
- You write shared code in Kotlin β especially the logic (like calculations, API calls, or data processing).
- Then, you plug that code into different apps β one for Android, one for iOS, etc.
- It’s mostly about code sharing, not UI.
Example:
If you’re building a weather app:
- You can write the code that fetches weather data once with KMP.
- Then use it on both Android and iOS, even though the screens might look different.
π¨ Compose Multiplatform β The Artist Drawing the Screens
Compose Multiplatform is like a magic crayon box that lets you draw your app’s screens once and show them on Android, desktop, web, etc.
- It’s based on Jetpack Compose (Androidβs modern UI toolkit).
- But now you can use it to build user interfaces for other platforms too (like desktop apps with Compose for Desktop or web with Compose for Web).
- It’s about UI sharing, and it often works well with Kotlin Multiplatform.
Example:
You can design one screen layout for your weather app:
- And show that same screen on Android, Windows, macOS, and even the web.
π€ TL;DR - How They Work Together
| Feature | Kotlin Multiplatform π οΈ | Compose Multiplatform π¨ |
|---|---|---|
| What it does | Shares logic/code | Shares UI/screens |
| Focus | Background stuff (API, data, logic) | Frontend look & feel |
| Platforms | Android, iOS, web, server, desktop | Android, Desktop, Web |
| Can they work together? | β Yes! Compose uses KMP for shared logic | β Yes! KMP can power Compose apps |
π§© Summary
- π οΈ KMP = Share your appβs brains (logic, calculations).
- π¨ Compose MP = Share your appβs face (UI).
- π§ + π¨ = You get a smart and good-looking app that works on many platforms.
