Panduan mengelola configuration dan secrets menggunakan Viper dan environment variables.

​
⚙️ Configuration Management

​
Using Viper

type Config struct {
    Server   ServerConfig
    Database DatabaseConfig
    JWT      JWTConfig
}

type ServerConfig struct {
    Port string `mapstructure:"port"`
    Env  string `mapstructure:"env"`
}

func LoadConfig() (*Config, error) {
    viper.SetConfigName("config")
    viper.SetConfigType("yaml")
    viper.AddConfigPath("./configs")
    
    viper.AutomaticEnv()
    
    if err := viper.ReadInConfig(); err != nil {
        return nil, err
    }
    
    var config Config
    if err := viper.Unmarshal(&config); err != nil {
        return nil, err
    }
    
    return &config, nil
}

​
Config File (YAML)

server:
  port: 8080
  env: development

database:
  host: ${DB_HOST}
  port: ${DB_PORT}
  user: ${DB_USER}
  password: ${DB_PASSWORD}
  name: ${DB_NAME}

jwt:
  secret: ${JWT_SECRET}
  expiry: 24h

🔐 Secrets Management

​
Environment Variables

# .env
DB_HOST=localhost
DB_PORT=3306
DB_USER=root
DB_PASSWORD=secret
DB_NAME=windsurf_db

JWT_SECRET=your-super-secret-key

​
Best Practices

  • ✅ Never commit .env to git
  • ✅ Use .env.example as template
  • ✅ Rotate secrets regularly
  • ✅ Use different secrets per environment
  • ✅ Use secret management tools (Vault, AWS Secrets Manager)
