rk-grpc

Inject middlewares & server configuration of gRPC and grpc-gateway from YAML file.

This belongs to rk-boot family. We suggest use this lib with rk-boot.

Architecture

image

Quick Start

In the bellow example, we will start microservice with bellow functionality and middlewares enabled via YAML.

  • gRPC and grpc-gateway server
  • gRPC server reflection
  • Swagger UI
  • CommonService
  • Docs
  • Prometheus Metrics (middleware)
  • Logging (middleware)
  • Meta (middleware)

Please refer example at example/boot/simple.

Installation

go get github.com/rookie-ninja/rk-grpc/v2

1.Prepare .proto files

show
  • api/v1/greeter.proto
syntax = "proto3";

package api.v1;

option go_package = "api/v1/greeter";

service Greeter {
  rpc Greeter (GreeterRequest) returns (GreeterResponse) {}
}

message GreeterRequest {
  bytes msg = 1;
}

message GreeterResponse {}
  • api/v1/gw_mapping.yaml
type: google.api.Service
config_version: 3

# Please refer google.api.Http in https://github.com/googleapis/googleapis/blob/master/google/api/http.proto file for details.
http:
  rules:
    - selector: api.v1.Greeter.Greeter
      get: /v1/greeter
  • buf.yaml
version: v1beta1
name: github.com/rk-dev/rk-boot
build:
  roots:
    - api
  • buf.gen.yaml
version: v1beta1
plugins:
  # protoc-gen-go needs to be installed, generate go files based on proto files
  - name: go

2.Generate .pb.go files with buf

show
$ buf generate --path api/v1
.
