Building a Local-First, End-to-End Encrypted, and Reactive App: A SQLite Sync Engine Implementation

The author attempted to build a local-first, end-to-end encrypted, and reactive application with data stored in a local SQLite database and synced to a remote server. Initial attempts using Electric and PGlite encountered performance and stability issues. Ultimately, a simpler approach was chosen: using SQLite with simple polling for data synchronization, and leveraging the Broadcast Channel API and triggers for reactive updates. This solution proved efficient for single-user scenarios, resulting in a highly responsive application with minimal loading times.
