grpc-core

A minimal Node.js helper library for building gRPC microservices, currently at version 1.0.6 (stable, low release cadence). Provides GrpcServer, GrpcService, and GrpcClient abstractions that simplify exposing class methods as gRPC endpoints. Differentiators: automatic method-to-RPC mapping, private method exclusion (underscore-prefixed), and async support. Requires Node >= 8.10 and depends on the `grpc` package. Less flexible than full-featured frameworks like `@grpc/proto-loader` + `@grpc/grpc-js`, but offers a cleaner OOP pattern.
