Custom Storage Client

Overview

The StorageClient interface is designed to be implemented by platform-specific storage solutions, such as SQLite, ObjectBox, Custom Hardware or FileSystem. This interface allows the Mobile SDK to interact with the storage layer without being tied to a specific implementation.

This guide provides a demo implementation of in-memory client. This is useful for testing or development purposes, but it is not suitable for production use. But we can create a custom storage provider to persist data.

Implementing a Custom Storage Provider

App.tsx

class CustomStorageClient: StorageClient {

    private var keyshareDaoSet: Set<ReconcileStoreDao> = []

    func write(dao: ReconcileStoreDao) async {
        if !keyshareDaoSet.insert(dao).inserted {
            keyshareDaoSet.remove(dao)
            keyshareDaoSet.insert(dao)
        }
    }

    func read(key: String) async throws -> ReconcileStoreDao? {
        return keyshareDaoSet.first { $0.keyId == key }
    }
}
