YAML configuration reader — typed config loading with environment overlay

Go Ready MD

Config Loading with Environment Override go

type AppConfig struct {
    Server struct {
        Port int    `yaml:"port" required:"true"`
        Host string `yaml:"host" default:"0.0.0.0"`
    } `yaml:"server"`
    Database database.Config `yaml:"database"`
}

// Load base config, then overlay dev-specific values
cfg, err := config.Load[AppConfig]("config.yml")
cfg, err = config.Overlay(cfg, "config.dev.yml")
err = config.Validate(cfg)

About

Loads YAML configuration files into typed Go structs with environment variable overlay support. Validates required fields, applies defaults, and merges environment-specific overrides following a base-then-env cascade.
