Features

• Reactive SQLite Libraries - A reactive state management framework that combines SQLite persistence with reactive data streaming for automatic UI updates.
• State Materialization - Processes immutable event logs into relational database tables to derive the application state.
• Local-First Persistence - Uses a relational database on the client side to provide synchronous data reads and offline-first functionality.
• Persistence & Durability - Saves data to a durable storage layer so it survives browser refreshes and server restarts.
• Event Stores - Implements a data store that persists sequences of events for state reconstruction via materializer functions.
• Local-First Databases - Uses a local database as the primary data source to enable synchronous reads and offline-first functionality.
• Log Materialization - Transforms append-only event logs into a concrete local SQLite database to derive current application state.
• Offline Data Management - Ensures the application remains fully operational during network outages by maintaining state in a local database.
• Reactive Data Queries - Binds database queries to UI frameworks using hooks that trigger automatic updates when underlying data changes.
• SQLite Storage Adapters - Uses a relational SQLite schema to structure and store application state locally or on a server.
• Local Database Persistence - Stores application data in a local database using the browser file system for persistence across sessions.
• Background Data Synchronization - Implements mechanisms for updating local data stores from remote sources without interrupting the user interface.
• Event Sourcing - Manages application state as an immutable sequence of events to ensure data consistency and enable historical debugging.
• Offline-First Synchronization - Ships a push-pull synchronization engine and event logs to keep local and remote states consistent offline.
• Append-Only Event Logs - Distributes append-only event logs between clients and servers to ensure deterministic state reconstruction.
• State-Synchronized Bindings - Binds global state management to frontend libraries using reactive hooks to synchronize the user interface.
• Event-Driven State Managers - Provides a centralized mechanism to update application state via typed events and materializer functions.
• Reactive Data Bindings - Binds a local SQLite database to frontend frameworks to automatically update the UI when data changes.
• Reactive State Managers - Includes a built-in reactivity system that tracks data changes to automatically synchronize and update UI components.
• Reactive UI Updates - Triggers automatic UI updates when underlying data changes using a type-safe schema for events and queries.
• Main Thread Offloading - Moves computationally expensive state management and data processing tasks from the main UI thread to background web workers.
• Offline-First Web Apps - Provides a framework for building applications that function without internet by prioritizing local storage and synchronization.
• Real-time Collaboration - Enables real-time synchronization of application data across multiple users and devices for shared interactive experiences.
• State Inspection Interfaces - Provides visual tools for tracking and displaying real-time state changes and data flow within the application.
• Data Schema Definitions - Specifies database table structures and event types that translate events into permanent state changes.
• Offline-First Persistence - Stores events locally to remain functional without connectivity and synchronizes pending changes once online.
• Time-Travel Debuggers - Provides a developer interface to inspect event logs and reconstruct state transitions for time-travel debugging.
• Type-Safe Event Contracts - Enforces a type-safe contract for events and queries to ensure unidirectional data flow.
• Event Logs - Maintains an immutable log of every event to enable historical state reconstruction and analysis.
• Push-Pull State Distribution - Implements a push-pull synchronization engine to distribute immutable events across clients and servers.
• Optimistic Offline Queues - Maintains a local queue of pending changes during network outages with automatic synchronization once connectivity is restored.
• Presence Tracking - Tracks and shares the online status and activity of users within shared sessions.
• WebSocket State Synchronization - Propagates data events between multiple clients in real-time using a WebSocket backend for shared state consistency.
• State Management - State management framework based on reactive SQLite.
