grpclb

grpclb is a gRPC load balancer for Node.js integrated with etcd for service discovery. Version 1.3.4 is the current stable release. It provides client-side round-robin load balancing via JavaScript Proxy or client pool. Key differentiators: lightweight, peer dependency with grpc avoids duplicate grpc copies, supports both dynamic and static gRPC code. Package is mature but not frequently updated.
