This package is a really lightweight environment-type config loader that enhance the normal use case of os.Getenv("ENV_KEY"). This package will help us get the expected datatype.

This package can load environment data that is defined from OS level, hardcoded map[string]string, or .env file easily.

• Run go get github.com/tianrosandhy/goconfigloader
• Init new configloader : cfg := goconfigloader.NewConfigLoader()
• Get value :
  • cfg.GetString("YOUR_CONFIG_KEY")
  • cfg.GetInt("YOUR_CONFIG_KEY")
  • cfg.GetFloat64("YOUR_CONFIG_KEY")
  • cfg.GetBool("YOUR_CONFIG_KEY")

1. Define default config from map[string]string Optinally, you can define a map[string]string with pairs of default key=>value.

defaultConfig := map[string]string{
    "API_URL": "http://localhost:9090",
    "PORT": "9090",
    "IS_API_ENABLED": "true",
}
cfg := goconfigloader.NewConfigLoader(defaultConfig)
//
cfg.GetBool("IS_API_ENABLED") // return TRUE

2. Define default config from .env file If you have .env file stored in your project path, this package will try to load that file too

API_URL="http://localhost:9000"
PORT=9090
IS_API_ENABLED=true

cfg := goconfigloader.NewConfigLoader(defaultConfig)
//
cfg.GetInt("PORT") // return 9090

3. Define environment from OS level By default this package will call the os.Getenv("KEY") first, so any environment that you define in OS level will be handled like usual.
