RvLite Vector Database

RvLite is a lightweight, embeddable vector database designed for universal execution across Node.js, browsers, and Edge environments. It leverages WebAssembly for high performance and portability, resulting in a small bundle size of approximately 850KB. The current stable version is 0.2.6. It supports multiple querying paradigms, including vector search with cosine, Euclidean, or dot product distance, standard SQL with extensions for distance operations, Cypher for property graph queries (Neo4j-compatible syntax), and SPARQL for RDF triple store interactions. Persistence options include file-based storage in Node.js and IndexedDB in browsers. The package provides a comprehensive SDK for programmatic interaction and a CLI for command-line operations and an interactive REPL, making it suitable for a wide range of AI-driven applications like RAG and knowledge graphs. Its key differentiators are its multi-query language support and extreme portability across JavaScript runtimes.
