• ✅ Insert: Vector inserted with ID test_vector
• ✅ Count: Returns correct count (1 vector)
• ✅ Search: Returns 1 result with perfect score (0.000000)
• ✅ Delete: Successfully deletes vector (returns true)

🎯 Verified API Methods

Constructor

const db = new VectorDb({
  dimensions: 3,
  maxElements: 100,
  storagePath: '/path/to/db.db'
});

Insert (async)

const id = await db.insert({
  id: 'my-id',
  vector: new Float32Array([0.1, 0.2, 0.3])
});

Search (async)

const results = await db.search({
  vector: new Float32Array([0.1, 0.2, 0.3]),
  k: 10
});

Count (async)

const count = await db.len();

Delete (async)

const deleted = await db.delete('my-id');

📋 Configuration Details

package.json

{
  "name": "@ruvector/core-linux-x64-gnu",
  "version": "0.1.1",
  "main": "index.js",
  "type": "commonjs",

  "cpu": ["x64"],
  "files": [
    "index.js",
    "ruvector.node",
    "*.node",
    "README.md"
  ]
}

index.js (Loader)

const { join } = require('path');

let nativeBinding;
try {
  nativeBinding = require('./ruvector.node');
} catch (error) {
  throw new Error(
    'Failed to load native binding for linux-x64-gnu. ' +
    'This package may have been installed incorrectly. ' +
    'Error: ' + error.message
  );
}

module.exports = nativeBinding;

🚀 Ready to Publish

Prerequisites Complete

• ✅ Native binary built and included (4.3MB)
• ✅ Package.json correctly configured
• ✅ Module loader working
• ✅ All tests passing
• ✅ API methods verified
• ✅ npm pack shows correct size (4.5MB unpacked, 1.9MB compressed)

🔗 Related Packages (Pending)

Main Package: @ruvector/core

• Platform detection and auto-loading
• TypeScript definitions
• Unified API across platforms

Other Platform Packages

• @ruvector/core-linux-arm64-gnu (pending)
• @ruvector/core-darwin-x64 (pending)
• @ruvector/core-darwin-arm64 (pending)
• @ruvector/core-win32-x64-msvc (pending)

🎓 Key Learnings

1. NAPI-RS Async Methods: All database operations are async (return Promises)
2. API Differences: Method names differ from FFI bindings:
   • count() → len()
   • Parameters passed as objects, not positional
3. Storage Locking: Each database instance needs unique storage path
4. Module Loading: Loader handles missing binary with clear error message
5. File Inclusion: Explicit listing in files array required for binaries

✅ Success Criteria Met

• Native binary included in package
• Binary loads without errors
• Database can be created
• Insert operations work
• Search operations work
• Delete operations work
• Count operations work
• API matches documentation
• npm pack shows correct size
• All tests automated and passing

📝 Next Steps

1. Publish linux-x64-gnu (current platform)
2. Build and test other platforms via GitHub Actions
3. Publish all platform packages
4. Publish main @ruvector/core package
5. Test cross-platform installation
