Configuration

type Config struct {
    Port    int           `env:"PORT" default:"9900"`
    DBURL   string        `env:"DB_URL" required:"true"`
    Timeout time.Duration `env:"TIMEOUT" default:"5s"`
    Origins []string      `env:"CORS_ORIGINS"`          // comma separated
    Redis   RedisConfig   `envPrefix:"REDIS_"`          // REDIS_ADDR, REDIS_DB, ...
}

// Global module: every provider can take *Config.
Imports: []*dygo.Module{config.ForRoot[Config](config.Files(".env.local", ".env"))}

// Or load it yourself before Create (for the listen address, middleware options):
cfg, err := config.Load[Config](config.Files(".env"))

Real environment variables win over .env files. Every missing or bad value is reported together and stops the boot. config.ForFeature[T](config.Prefix("USERS_")) is a non-global module for one feature’s settings; config.Env(map) replaces the environment in tests; config.Validate(schema) runs a validation schema after loading.
