SochDB Node.js Examples - Test Report

Summary

All package.json files and imports have been successfully updated from @sushanth/toondb to @sochdb/sochdb. Package names and ToonDB references in code have been renamed to SochDB.

Testing Results

✅ Working Examples

1. Basic Examples (Embedded Mode)

  • Location: sochdb-nodejs-examples/basic/
  • Status: ✅ WORKING
  • Example: basic_kv.js
  • Notes:
    • Uses embedded Database mode: Database.open(path) (sync)
    • Requires SOCHDB_LIB_PATH environment variable pointing to native library
    • All operations working: put, get, putPath, getPath, scanPrefix
    • Fixed to use scanPrefix (async generator) instead of scan
    • Fixed to pass Buffer objects instead of strings

Run Command:

cd sochdb-nodejs-examples/basic
SOCHDB_LIB_PATH=/Users/sushanth/sochdb/sochdb/target/debug/libsochdb_storage.dylib node basic_kv.js

2. RAG Example (Embedded Mode)

  • Location: sochdb-nodejs-examples/rag/
  • Status: ✅ WORKING
  • Example: demo.js
  • Notes:
    • Uses embedded Database mode
    • Fixed vectorStore.js to use Buffer objects throughout
    • Fixed to use scanPrefix with async generator pattern
    • Updated Database.open() to sync version
    • Mock mode works (doesn't require OpenAI API key)
    • Full RAG pipeline working with chunking, embedding, and retrieval

Run Command:

cd sochdb-nodejs-examples/rag
SOCHDB_LIB_PATH=/Users/sushanth/sochdb/sochdb/target/debug/libsochdb_storage.dylib node demo.js

⚠️ Examples Requiring IPC/Server Mode

The following examples use features that are not yet available in embedded (FFI) mode:

3. SQL Example

  • Location: sochdb-nodejs-examples/basic/sql_check.js
  • Status: ⚠️ REQUIRES IPC MODE
  • Issue: db.execute() for SQL is not available in EmbeddedDatabase
  • Needs: IPC client mode with server running

4. Support Agent Example

  • Location: sochdb-nodejs-examples/support-agent/
  • Status: ⚠️ REQUIRES IPC MODE
  • Issues:
    • Uses await Database.open() (IPC mode)
    • Uses db.execute() for SQL operations
    • Requires SQL schema and transactions
  • Needs: IPC client mode with server running

5. LangGraph Memory Example

  • Location: sochdb-nodejs-examples/langgraph-memory/
  • Status: ⚠️ REQUIRES IPC MODE
  • Issues: Uses await Database.open() (IPC mode)
  • Needs: IPC client mode with server running

6. Graph Overlay Examples

  • Location: sochdb-nodejs-examples/graph_overlay_examples/
  • Status: ⚠️ REQUIRES IPC MODE
  • Issues:
    • Uses await Database.open() (IPC mode)
    • GraphOverlay might require server mode
  • Needs: IPC client mode with server running

Key Fixes Applied

1. Package Updates

  • Updated all package.json files from @sushanth/toondb to @sochdb/sochdb
  • Updated version from ^0.3.3 to ^0.4.0
  • Renamed package names from toondb-* to sochdb-*

2. Import Updates

  • Updated all imports from @sushanth/toondb to @sochdb/sochdb
  • Updated in 13 source files across all examples

3. Code Reference Updates

  • Renamed ToonDBMemory class to SochDBMemory
  • Renamed ToonDBCheckpointer class to SochDBCheckpointer
  • Updated all string references from ToonDB to SochDB
  • Updated environment variables (TOONDB_PATH → SOCHDB_PATH)
  • Updated default paths (toondb_data_node → sochdb_data_node)

4. API Compatibility Fixes (basic_kv.js)

  • Changed from await Database.open() to Database.open() (sync)
  • Changed from db.scan() to db.scanPrefix() with async generator
  • Updated to use Buffer objects for keys instead of strings
  • Changed from await db.close() to db.close() (sync)

5. API Compatibility Fixes (rag/src/vectorStore.js)

  • Updated Database.open() from async to sync
  • Fixed all db.put() calls to use Buffer objects for both key and value
  • Fixed all db.delete() calls to use Buffer objects for keys
  • Updated scanPrefix() to use async generator pattern with for await
  • Fixed destructuring from [key, value] tuple format

Database Mode Comparison

Embedded Mode (FFI)

  • Usage: const db = Database.open(path) (sync)
  • Features: KV operations, path operations, transactions, scanPrefix
  • Pros: No server needed, direct FFI access, lightweight
  • Cons: No SQL support yet, no GraphOverlay yet
  • Requires: SOCHDB_LIB_PATH environment variable

IPC Mode

  • Usage: const db = await Database.open(path) (async)
  • Features: All features including SQL, GraphOverlay
  • Pros: Full feature set
  • Cons: Requires server process
  • Requires: Server running

Recommendations

  1. For Basic KV and RAG: Use embedded mode examples (working now)
  2. For SQL, Agents, LangGraph: Wait for server mode or implement IPC client support
  3. Documentation: Update example READMEs to specify which mode they use
  4. Future Work:
    • Add SQL support to EmbeddedDatabase
    • Add GraphOverlay support to EmbeddedDatabase
    • Or document how to run with server mode
