Conf

Read config from configuration file OR from environment variables, then unmarshal it into a struct.

1. You can use config file to set up your application. This step is optional.

   pg:
       host: 127.0.0.1
       port: 5432
   secret:
       authorizedKey: "key"

2. Use FetchConfig to load the config file.

   import "github.com/cloudcarver/edc/conf"
   
   type PG struct {
       Host string `yaml:"host"`
       Port int    `yaml:"port"`
   }
   
   type Secret struct {
       AuthorizedKey string `yaml:"authorizedKey"`
   }
   
   type Config struct {
       PG     PG     `yaml:"pg"`
       Secret Secret `yaml:"secret"`
   }
   
   func main() {
       config := Config{}
       err := conf.FetchConfig("conf.yaml", "MYAPP", &config)
       if err != nil {
           panic(err)
       }
       ...
   }

3. Start the application.

   MYAPP_PG_HOST=myapp.local go run main.go
