This webinar presentation covered offline storage options for building secure, offline-first mobile apps with Ionic Framework. It discussed key requirements for storage solutions including support across platforms, encryption, offline access, ease of use and deployment, data syncing, and querying. Common options like LocalStorage, WebSQL, IndexedDB, and SQLite were summarized and compared. Ionic Offline Storage was introduced as a powerful NoSQL option with encryption, querying, optional Couchbase integration, and support from Ionic. The presentation concluded with a demo of advanced data searching and resources for further information.

everywhere: any platform, any device,
any framework.
➔ Build for iOS, Android, Electron, PWAs, Web
➔ One codebase across all platforms
➔ Use basic web skills: HTML, JS, CSS
➔ Full access to Native APIs

6. Hybrid Architecture
HTML, CSS, JavaScript
Runs in a “browser” WebView
Wrapped in native app shell
Access device capabilities via plugins
Native runtime: Cordova or Capacitor
Deploy to App Stores, Desktop, and Web (PWA)
