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
## Quick Start
In the bellow example, we will start microservice with bellow functionality and middlewares enabled via YAML.
- [gRPC](https://grpc.io/docs/languages/go/) and [grpc-gateway](https://github.com/grpc-ecosystem/grpc-gateway) server
- [gRPC](https://grpc.io/docs/languages/go/) server reflection
- Swagger UI
- CommonService
- Docs
- Prometheus Metrics (middleware)
- Logging (middleware)
- Meta (middleware)
Please refer example at [example/boot/simple](example/boot/simple).
### Installation
```shell
go get github.com/rookie-ninja/rk-grpc/v2
```
### 1.Prepare .proto files
show
- api/v1/greeter.proto
```protobuf
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
```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
```yaml
version: v1beta1
name: github.com/rk-dev/rk-boot
build:
roots:
- api
```
- buf.gen.yaml
```yaml
version: v1beta1
plugins:
# protoc-gen-go needs to be installed, generate go files based on proto files
- name: go
out: api/gen
opt:
- paths=source_relative
# protoc-gen-go-grpc needs to be installed, generate grpc go files based on proto files
- name: go-grpc
out: api/gen
opt:
- paths=source_relative
- require_unimplemented_servers=false
# protoc-gen-grpc-gateway needs to be installed, generate grpc-gateway go files based on proto files
- name: grpc-gateway
out: api/gen
opt:
- paths=source_relative
- grpc_api_configuration=api/v1/gw_mapping.yaml
# protoc-gen-openapiv2 needs to be installed, generate swagger config files based on proto files
- name: openapiv2
out: api/gen
opt:
- grpc_api_configuration=api/v1/gw_mapping.yaml
```
### 2.Generate .pb.go files with [buf](https://docs.buf.build/introduction)
show
```
$ buf generate --path api/v1
```
```

### 5.Start server
```
$ go run main.go
```
### 6.Validation
show
#### 6.1 gRPC & grpc-gateway server
Try to test [gRPC](https://grpc.io/docs/languages/go/) & [grpc-gateway](https://github.com/grpc-ecosystem/grpc-gateway) Service with [curl](https://curl.se/) & [grpcurl](https://github.com/fullstorydev/grpcurl)
```shell script
# Curl to common service
$ curl localhost:8080/rk/v1/ready
{"ready":true}
```
#### 6.2 Swagger UI
Please refer **sw** section at [Full YAML](#full-yaml).
By default, we could access swagger UI at [http://localhost:8080/sw](http://localhost:8080/sw)
#### 6.3 Docs UI
Please refer **docs** section at [Full YAML](#full-yaml).
By default, we could access docs UI at [http://localhost:8080/docs](http://localhost:8080/docs)
#### 6.4 Prometheus Metrics
Please refer **middleware.prom** section at [Full YAML](#full-yaml).
By default, we could access prometheus client at [http://localhost:8080/metrics](http://localhost:8080/metrics)

#### 6.6 Meta
Please refer **meta** section at [Full YAML](#full-yaml).
By default, we will send back some metadata to client with headers.

#### 6.7 Send request
We registered /v1/greeter API in [grpc-gateway](https://github.com/grpc-ecosystem/grpc-gateway) server and let's validate it!

```
We registered api.v1.Greeter.Greeter API in [gRPC](https://grpc.io/docs/languages/go/) server and let's validate it!
```shell script
$ grpcurl -plaintext localhost:8080 api.v1.Greeter.Greeter

```
#### 6.8 RPC logs
Bellow logs would be printed in stdout.
The first block of log is from [grpc-gateway](https://github.com/grpc-ecosystem/grpc-gateway) request.
