microservice-config

Load config from a json file. Those configs are uses frequently to run a micro service.

How to use it

package main

import (
    microconfig "github.com/alvarios/microconfig"
    "github.com/kataras/iris/v12"
)

func main(){
    config := microconfig.NewConfigFromEnv()
    app := iris.New()
    app.Handle("GET", "/health", func(ctx iris.Context){
       ctx.Json([]byte("I'm ok")) 
    })
    app.Listen(config.Server.Port)
}

NewConfigFromEnv create a Configuration instance from a json file. The path to the json file is load from env an variable CONFIG_PATH
