Package Exports

@escher-dbai/rag-module
@escher-dbai/rag-module/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@escher-dbai/rag-module) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

RAG Desktop Module

Production-ready standalone NPM module providing enterprise-grade RAG (Retrieval-Augmented Generation) capabilities for desktop applications with complete local storage, zero external dependencies, and commercial-grade performance.

🎯 What This Module Provides

This is a fully self-contained RAG system that desktop applications can integrate for:

🔒 Complete Local Storage: 100% local processing with embedded Qdrant vector database
⚡ Professional Performance: HNSW optimization for sub-second semantic search
🛡️ Maximum Security: Zero external communications, all data stays on device
📦 Zero Dependencies: No external services, databases, or API calls required
🏢 Commercial Ready: Multi-tenant support for business applications

🚀 Quick Start

Installation

npm install @yourcompany/rag-desktop

Basic Usage

const RagModule = require('./src/RagModule');

// Initialize with local folder path
const rag = new RagModule('/path/to/your-rag-data-folder');

// Initialize embedded Qdrant and BGE-M3 models
await rag.initialize();
await rag.configure({
  embeddingModel: 'BAAI/bge-m3',
  embeddingDimensions: 1024,
  vectorStore: 'qdrant-embedded',  // Fully local embedded storage
  privacyLevel: 'anonymous',       // Maximum privacy
  chunkSize: 1024,
  searchTopK: 10
});

// Ready for production use!

🔒 Security-First Architecture (HIGHEST PRIORITY)

Complete Local Storage

✅ Zero External Communications: No network calls, APIs, or cloud services
✅ Embedded Qdrant Database: Professional vector database runs locally
✅ Local BGE-M3 Models: State-of-the-art embeddings generated on-device
✅ File-Based Configuration: All settings stored in local YAML files
✅ Anonymous ID Mapping: Optional privacy layer for sensitive data

Storage Architecture Options

Option 1 - Embedded Qdrant (Recommended - Production Performance)

// Configuration: demo-cli-folder/config/config.yaml
vectorStore: qdrant-embedded
embeddingModel: BAAI/bge-m3
embeddingDimensions: 1024
privacyLevel: anonymous

// Professional HNSW performance with complete local storage
// All data stored in: demo-cli-folder/qdrant-data/

Option 2 - Pure File Storage (Maximum Security)

// Configuration: example-configs/config-local-files.yaml
vectorStore: local-files
embeddingModel: BAAI/bge-m3
localFiles:
  documentsFile: documents.json
  searchIndexFile: search-index.json
  enableCompression: true
  enableEncryption: true

// Zero external dependencies, pure JavaScript implementation

📁 Local Folder Architecture

/your-rag-data-folder/          # Customer-specified storage location
├── config/
│   └── config.yaml             # Embedding models, vector store settings
├── qdrant-data/               # Embedded Qdrant database (583MB+ for production)
│   ├── collection/            # Vector collections and HNSW indices
│   ├── snapshots/            # Database snapshots for backup
│   └── collection-metadata.json  # Collection configuration
├── models/                    # BGE-M3 and other embedding models (local cache)
├── documents/                 # Processed document storage
├── search-indices/           # Local file-based search indices (if using local-files)
└── logs/                     # Application logs and debugging info

Key Benefits:

Customer Control: Each customer specifies their own storage path
Complete Isolation: No shared storage between different deployments
Backup Ready: Entire folder can be backed up as a single unit
Portable: Move folder to different machines while preserving all data
