grpc-node is a gRPC implementation for Node.js that provides both pure JavaScript and C-based client and server libraries for building remote procedure call services.
The project solves the problem of enabling Node.js applications to use gRPC, a high-performance RPC framework built on HTTP/2. The primary implementation, grpc-js, is written entirely in JavaScript without native C++ dependencies, making it portable across all platforms where Node.js runs. A deprecated C-based implementation using a C++ addon is available on an older branch for applications requiring it on Node.js versions up to 14. The project also includes supporting packages: proto-loader for loading .proto files, grpc-tools for distributing protoc and the gRPC Node protoc plugin, grpc-health-check for server health checking, and grpc-reflection for reflection API services.
Developers should choose grpc-node when building Node.js services that need to communicate via gRPC. The pure JavaScript implementation suits most modern Node.js deployments because it works on all current Node.js versions and platforms without compilation. The repository provides a comparison document between the pure JavaScript and C-based implementations to help developers understand the trade-offs between them. The supporting packages address common operational needs like protocol buffer compilation, service health monitoring, and server reflection.
The project maintains active development across multiple packages with coordinated updates. The codebase is written in TypeScript, providing type safety for users and maintainers. The repository accepts community contributions through standard open-source channels.
