GenosDB v0.0.30: Main Features

[estebanrfp]

Here's the summary of the main technical features of GenosDB

Main Features:

1. Persistent Storage (OPFS):

• Uses Origin Private File System (OPFS) for persistent storage
• Implements createSyncAccessHandle() within a Web Worker for better performance
• Stores serialized data in compressed MessagePack format using Pako

2. P2P Synchronization:

• Uses Trystero for peer-to-peer synchronization
• Supports encrypted channels with optional password
• Handles peer connection/disconnection events
• Detects and handles network state changes (online/offline)

3. Data Structure:

• Implements a graph structure with nodes and relationships
• Nodes contain: id, value, timestamp, and edges
• Maintains an inverted index for fast lookups by value

4. Main Operations:

• put(): Inserts/updates nodes
• get(): Gets node by ID
• find(): Searches nodes by value
• remove(): Deletes nodes
• update(): Updates node values
• link(): Creates relationships between nodes
• map(): Iterates over all nodes
• clear(): Clears the entire database

5. Advanced Features:

• SHA-256 based hash system for unique IDs
• Conflict management via resolveConflict()
• Cross-tab communication using BroadcastChannel
• Customizable event listeners (on/off)

6. Serialization/Efficiency:

• Serializes data with MessagePack
• Compresses data with Pako (deflate/inflate)
• Efficient deserialization directly from Uint8Array

7. Security and Performance:

• Checks OPFS availability
• Implements fallbacks for compatibility
• Offloads heavy operations to Web Worker
• Properly releases resources (revokeObjectURL)

8. Versioning System:

• Maintains local hash of the graph
• Timestamp of last update
• Synchronization protocol with hash and timestamp

This implementation demonstrates a robust design that combines efficient persistent storage with real-time synchronization, maintaining a good balance between performance and functionality.
