config

Application configuration from YAML, env vars, and flags.

Usage

cfg, err := config.Load("config.yaml", "MYAPP_", os.Args)
if err != nil {
    log.Fatal(err)
}

if err := cfg.Validate(); err != nil {
    log.Fatal(err)
}

// Access config
fmt.Println(cfg.Server.Port)
fmt.Println(cfg.Database.ConnectionString())

Precedence (highest to lowest):

1. Flags (--database.host=x)
2. Env vars (MYAPP_DATABASE_HOST=x)
3. YAML file
4. Defaults

Notes

Static configuration at startup. For dynamic runtime configuration, see settings/.
