The implementation focuses on: +This document outlines the implementation of secure storage for the TimeSafari app using a platform-agnostic approach with Capacitor and absurd-sql solutions. The implementation focuses on: 1. **Platform-Specific Storage Solutions**: - - Web: absurd-sql with IndexedDB backend - - iOS: SQLCipher with Keychain integration - - Android: SQLCipher with Keystore integration - - Electron: SQLite with secure storage + - Web: absurd-sql with IndexedDB backend and Web Worker support + - iOS/Android: Capacitor SQLite with native SQLite implementation + - Electron: Node SQLite (planned, not implemented) 2. **Key Features**: - - Encrypted storage using SQLCipher - - Platform-specific security features - - Migration support from existing implementations + - Platform-agnostic SQLite interface + - Web Worker support for web platform - Consistent API across platforms + - Performance optimizations (WAL, mmap) + - Comprehensive error handling and logging + - Type-safe database operations + - Storage quota management + - Platform-specific security features -## Quick Start - -### 1.

Instead, we initialize the database early in the app startup (for example, in our main entry file) so that it is ready before any component (or other code) tries to use it. - -### How It Works - -- **PlatformServiceFactory.getInstance()** returns a singleton instance of the appropriate platform service (for example, Web, Capacitor, Electron, or PyWebView) and assigns it (for example, to `app.config.globalProperties.$platform`). -- The platform service (via its `getSQLite()` method) returns a SQLiteOperations interface (which is platform-agnostic). -- **The actual database initialization** (for example, creating/opening the database, running migrations, setting PRAGMAs) is done by calling `initialize(config)` on the SQLiteOperations object. - -### Example (in main.common.ts) - -Below is an example diff (or “edit”) applied in our main entry (for example, in `src/main.common.ts`) so that the SQLite database is initialized immediately after setting the global property: - -```typescript -app.config.globalProperties.$platform = PlatformServiceFactory.getInstance(); - - (async () => { - const platform = app.config.globalProperties.$platform; - const sqlite = await platform.getSQLite(); - const config = { name: "TimeSafariDB", useWAL: true }; // (or your desired config) - await sqlite.initialize(config); - logger.log("[App Init] SQLite database initialized."); - })(); -``` - -### 3.
