jenv - package for making your json files configurable with .env files

---

Usage

• create json file which will be your data source

{
    "ID": "123",
    "Name": "Some name",
    "Boolval": "Some bool"
}

Notice how fields values are wrapped with quotes " - each field value for parsing with current package should be wrapped

• create a struct which will be a target for your json file parsing

import (
	"encoding/json"

	lj "github.com/webornottoweb/jenv/pkg/json"
)

type User struct {
	ID      lj.JEnvInt
	Name    lj.JEnvString
	Boolval lj.JEnvBool
}

Notice, how local json package implementation was described with lj

• start parsing with Go encoding/json package

func main() {
	file, _ := ioutil.ReadFile("data.json")

	var user User

	err := json.Unmarshal([]byte(file), &user)
	if err != nil {
		panic(err)
	}

	fmt.Println(user)
}

Result: {123 Some name false}

• if u want to use env value, just wrap json value with env[]

{
    "ID": "123",
    "Name": "env[USER_NAME]",
    "Boolval": "env[USER_BOOL]"
}

Notice that you should have .env file with provided USER_NAME and USER_BOOL variables

Result: {123 name from env true}

Tasks

• implement raw array values parsing (strings/integers/booleans)
• tests cover
