gRPC on Node.js
Implementations
C-based Client and Server
Directory: packages/grpc-native-core (see here for installation information)

This is the existing, feature-rich implementation of gRPC using a C++ addon. It works on all LTS versions of Node.js on most platforms that Node.js runs on.
Pure JavaScript Client
Directory: packages/grpc-js-core
This library is currently incomplete and experimental, built on the experimental http2 Node module.
This library implements the core functionality of gRPC purely in JavaScript, without a C++ addon. It works on the latest version of Node.js (with the --expose-http2 flag set) on all platforms that Node.js runs on.
