gRPC-GCP for Node.js

A Node.js module (v1.0.1, updated Aug 2022, infrequent releases) extending gRPC with Google Cloud Platform-specific features like channel pooling and affinity-based routing. It provides a GcpApiConfig from a JSON definition, a custom channel factory override, and a call invocation transformer to enable features such as BIND/BOUND/UNBIND affinity commands. Works with both 'grpc' and '@grpc/grpc-js' packages via a factory pattern. Differentiated by its GCP-specific optimizations over plain gRPC.
