react-native-async-storage/async-storage

This system is a cross-platform asynchronous storage library for React Native and Expo applications, supporting Android, iOS, and web environments. It provides a unified API for persisting key-value data, featuring a modern multi-database architecture that replaces legacy singleton patterns with scoped instances. The project includes comprehensive tooling, such as build scripts, configuration plugins, and example applications, to facilitate integration and validation across diverse development stacks.

This change introduces new example applications for the Async Storage library, providing a Compose Multiplatform app (Android and iOS) and a React web app. The Compose example demonstrates basic UI interactions using MaterialTheme and edge-to-edge display, while the web example offers a tabbed interface to run basic and performance tests against both the new and legacy storage implementations, complete with a test runner view for logging results.

This release introduces Async Storage v3, migrating the project to a monorepo structure with a new Kotlin Multiplatform \shared-storage\ core library for Android and Apple platforms. The API has changed to support multiple named databases via a new \createAsyncStorage(name)\ factory function, replacing the previous single-instance singleton pattern. The legacy Objective-C \RCTAsyncLocalStorage\ implementation has been removed in favor of the new native modules, and the repository now uses Yarn 4 and Turborepo for build orchestration.

A new Expo config plugin, @react-native-async-storage/expo-with-async-storage, has been introduced to automatically configure the local Maven repository for Android builds in managed and bare Expo projects. This plugin adds the necessary repository path to the project's build.gradle file, ensuring that the local artifact is correctly resolved. Note that this plugin is no longer required for Async Storage version 3.1.0 and above, as the artifact is now provided via Maven Central.

A new shell script, scripts/build-native-lib.sh, has been added to automate the build and packaging of the shared-storage native libraries for Android and Apple platforms. This script handles assembling the Android AAR and publishing it to Maven Local, as well as building the Apple XCFramework. Notably, it includes specific logic to resolve macOS symlinks within the framework structure to ensure compatibility with npm distribution, addressing issues where compression breaks symbolic links.

The examples/common-tests directory now provides a unified React Native test application to validate the @react-native-async-storage/async-storage library. This app includes a UI with tabs for Basic and Performance tests, supporting both the current API and legacy modes. The Basic tests verify core operations like setting, getting, removing, and clearing single or multiple keys, while Performance tests measure the time taken to save large data sets and handle a large number of keys. The implementation uses a shared test runner infrastructure to log results and handle assertions, ensuring consistent validation across different storage configurations.

This change introduces new example applications across multiple platforms to demonstrate the library's capabilities. The iOS example (\compose-ios\) is a SwiftUI app that wraps a Kotlin Compose view to perform shared storage operations (set, read, delete). The Expo example (\expo\) is configured with the \@react-native-async-storage/expo-with-async-storage\ plugin and uses the new architecture. The React Native example (\react-native\) is a multi-platform app supporting Android, iOS, macOS, visionOS, and Windows, utilizing \react-native-test-app\ for configuration. The Web example (\web\) is a Vite-based React application using Tailwind CSS. All examples include necessary configuration files (tsconfig, eslint, metro/babel) and boilerplate code to run the \TestApp\ component.

The project now includes a \.clang-format\ file to standardize C++ code style based on the LLVM profile, and a \tsconfig.base.json\ file that establishes a strict TypeScript compilation baseline. This base configuration enforces strict type checking, enables source maps and declaration files, and sets the module resolution to Node with CommonJS output, ensuring consistent build behavior across the codebase.

The Android implementation of AsyncStorage has been rewritten to use the Room database library with Write-Ahead Logging (WAL) enabled, replacing the previous storage mechanism. This change introduces a new \LegacyStorageModule\ that automatically migrates existing data from the old \RKStorage\ database file to the new Room schema, ensuring user data is preserved during the upgrade. The new architecture improves thread safety and concurrency by utilizing Kotlin Coroutines and separate dispatchers for read and write operations, while also enforcing stricter SQL standards (such as non-null primary keys) that were previously violated by the legacy implementation.

Async Storage has been upgraded to version 3, shifting from a global singleton to a scoped storage model where applications must explicitly create storage instances bound to a specific database name via the new \createAsyncStorage\ factory. This change is implemented across the native layers (Android Kotlin, iOS Swift, and JS) using a new \StorageRegistry\ to manage instances and a \SharedStorage\ backend, while the legacy v2 API is preserved behind \legacy\_\ prefixed methods and a \getLegacyStorage\ singleton to ensure backward compatibility during migration.

The ESLint configuration in packages/eslint-config has been updated to use the new flat config format (index.js), replacing the previous structure. This change integrates the @rnx-kit/eslint-plugin recommended rules, enables Prettier with strict error enforcement, and disables specific rules like no-console and react-in-jsx-scope to align with current project standards.

The repository has been restructured into a monorepo using Yarn workspaces and Changesets, introducing new dependency manifests (package.json, build.gradle.kts, requirements.txt, Gemfile) for the root, the core async-storage package, and multiple example applications (React Native, Expo, Web, Compose). This update aligns the example apps with React Native 0.79.6 and React 19, upgrades the Android build configuration to AGP 8.10.1 and Kotlin 2.2.10, and pins documentation tooling to MkDocs Material 9.6.20 and Python 3.11.
