LogosDB

Fast semantic vector database (HNSW + mmap) for Node.js. Version 1.0.0 uses zero-copy memory-mapped storage for local-only deployment, with O(log n) approximate nearest neighbor search. Ships TypeScript types and prebuilt N-API binaries via @mmomtchev/prebuild-install, falling back to node-gyp rebuild (C++17, no CMake). Provides timestamp ranges, distance metrics (IP, Cosine, L2), and full CRUD. Supports Linux, macOS, Windows (x64, arm64). Node >= 16 required.
