About

gRPC is a modern open-source high-performance Remote Procedure Call (RPC) framework that can run in any environment. It can efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking, and authentication. It is also applicable in the last mile of distributed computing to connect devices, mobile applications, and browsers to backend services.

Development

Debug

• GUI Client for GRPC Services - BloomRPC aims to give the simplest and efficient developer experience for exploring and querying your GRPC services. (Inspired by Postman and GraphQL Playground)
• A gRPC CLI interface for easy testing against gRPC servers with Node.js REPL

grpcc --proto ./service/myservice.proto --address 127.0.0.1:3466

Build

./scripts/install-protoc.sh
npm install

https://github.com/google/protobuf/releases/latest

Generate Stubs

npm run generate

1. JS for Protocol Buffer

protoc \
  --js_out="import_style=commonjs,binary:${OUT_DIR}"

https://github.com/google/protobuf/releases/latest

2. JS for gRPC Stubs

protoc \
  --plugin="protoc-gen-grpc=`which grpc_tools_node_protoc_plugin`" \
  --grpc_out="${OUT_DIR}"

https://www.npmjs.com/package/grpc-tools

3. TypeScript Typing Definations for Protocol Buffer & gRPC Stubs

protoc \
  --plugin="protoc-gen-grpc=node_modules/grpc_tools_node_protoc_ts/bin/protoc-gen-ts" \
  --grpc_out="${OUT_DIR}"

https://github.com/agreatfool/grpc_tools_node_protoc_ts

4. JS & TS for gRPC Web

protoc \
  --plugin="protoc-gen-ts=node_modules/ts-protoc-gen/bin/protoc-gen-ts" \
  --ts_out="service=true:${OUT_DIR}"

Protocol Buffer

Thanks to the ecosystem of gRPC, we can generate OpenAPI Specification from our gRPC proto definitions automatically.

We are using gRPC to JSON proxy generator following the gRPC HTTP spec as the OpenAPI Specification generator (protoc-gen-openapiv2), and using Like grpc-gateway, but written in node and dynamic project to serve an HTTP RESTful API to gRPC proxy.
