【Compose Multiplatform】Implementing Local Persistent Storage with DataStore
2024, Jul 10
Introduction
In pure Android projects
we can directly use the native DataStore
but in Compose Multiplatform projects
how can we continue using DataStore seamlessly?
This article will introduce how to implement
DataStore local storage in a cross-platform environment

- 【Compose Multiplatform】專案轉移探討與開發指南
- 【Compose Multiplatform】手機使用依賴注入Koin
- 【Compose Multiplatform 】跨平台App但Android需要context作法並搭配Koin

- 【Compose Multiplatform】CMP中使用ROOM開發資料庫 - [KSP2] Annotation value is missing in nested annotations
- 【Compose Multiplatform】CMP專案中導入CocoaPods及無CocoaPods情況下使用IOS Swift/Obj-C
Implementation Steps
1. Import Libraries
Add to your .toml file:
Add to your build.gradle.kts:
2. Implement DataStore for Each Platform
Create expect functions and local storage names:
Android platform implementation:
iOS platform implementation:
3. Using DataStore in commonMain
Use the interfaces implemented above
to use DataStore in commonMain:
4. Add Koin Module (Optional)
If you want to use Koin for dependency injection, you can set it up like this:
Conclusion
- Compose Multiplatform allows us to use DataStore in cross-platform projects
- Through proper encapsulation, we can use DataStore API uniformly across different platforms
- Using DataStore simplifies the implementation of local data persistence
- Combined with dependency injection frameworks like Koin, DataStore instances can be better managed
