How to override configuration?-CodePudding

We have configuration file per deploy environment, as shown in below code:

configs/.dev.env

  deploy_env=dev

configs/.env

  deploy_env=local

main.go

package main

import (
    "fmt"
    "os"

    "github.com/joho/godotenv"
)

func main() {
    err := godotenv.Load("./configs/.env") // load
    if err != nil {
        fmt.Println("unable to load")
    }
    err = godotenv.Load("./configs/.dev.env") // expecting to override configuration
    if err != nil {
        fmt.Println("unable to load")
    }
    fmt.Println(os.Getenv("deploy_env")) // Got output as: local       
                                         // Expecting output: dev
}

How to override configuration? expecting deploy_env to set as dev?

Use Overload instead of Load
