Config-loader allows you to load configuration values from a file, environment variable and flag whilst using cobra
In your init() function you will need to call config.Init(cmd) and to register any flags used in the config structure.
You can then define your configuration struct like so with support for both env and flag tags.
type exampleConfig struct {
Env string `env:"CONFIG_ENV"`
Flag string `flag:"CONFIG_FLAG"`
}
Within your executor for the cobra command you then simply run config.Load(cmd, cfg) with cfg being a pointer to the configuration struct.
You can see an example usage of this library in example/main.go
