helius-laserstream

A high-performance TypeScript client for streaming real-time Solana data via Laserstream (gRPC-based Yellowstone fork). Version 0.3.2 supports automatic reconnection, slot tracking, account/transaction/block/slot subscriptions, and configurable replay. N-API Rust bindings provide low latency. Differentiates from WebSocket-based clients by offering gRPC streaming with higher throughput and advanced control over keepalive, flow control, and compression.
