Build microservice with rk-boot and let the team take over clean and tidy code.
## Concept
rk-boot is a library which can manage backend service dependencies with YAML.
Standardize, unify and simplify microservice is huge challenge when project are getting bigger. Build microservice with rk-boot and let the team take over clean and tidy code.
## Quick Start
We will start [gin-gonic/gin](https://github.com/gin-gonic/gin) server with rk-boot.
### Install
```shell
go get github.com/rookie-ninja/rk-boot/v2
go get github.com/rookie-ninja/rk-gin/v2
```
### Code
boot.yaml
```yaml
---
gin:
- name: greeter # Required
port: 8080 # Required
enabled: true # Required
sw:
enabled: true # Optional, default: false
```
### Validate

entry := rkgin.GetGinEntry("greeter")
entry.Router.GET("/v1/greeter", Greeter)

func Greeter(ctx *gin.Context) {
ctx.JSON(http.StatusOK, &GreeterResponse{
Message: fmt.Sprintf("Hello %s!", ctx.Query("name")),
})
}
type GreeterResponse struct {
Message string
}
```
Check API
```shell script
$ go run main.go
$ curl -X GET localhost:8080/v1/greeter?name=rk-dev
{"Message":"Hello rk-dev!"}
$ curl -X GET localhost:8080/rk/v1/ready
{
"ready": true
}
$ curl -X GET localhost:8080/rk/v1/alive
{
"alive": true
}
```
