Arch Storage¶
Arch Storage gives Kotlin Multiplatform applications a shared API for reactive preferences and temporary values. The project keeps the build, CI, coverage and documentation conventions of Arch Lumber, with three storage modules extracted from Arch Toolkit.
| Module | What it provides |
|---|---|
| storage-core | Typed entries, Flow, mapping, defaults, JSON helpers and Compose integration |
| storage-memory | StateFlow-backed, process-local storage |
| storage-datastore | Persistent AndroidX DataStore Preferences adapter |
Start with installation and setup, then see concepts and recipes. API references are generated separately for core, memory and DataStore.
Platform support¶
Core and memory target Android, JVM, iOS (device and simulators), JavaScript and WasmJS.
DataStore persistence is available on Android, JVM and iOS. Its JS/Wasm factory deliberately
throws IllegalStateException: use MemoryStoreProvider there for nonpersistent values.
Native macOS artifacts are not configured. A desktop JVM application can run on macOS.
See the changelog for the changes included in each release.
