Environment Management

Manage different configurations for dev, staging, and production environments.

Running

# Development
APP_ENV=development go run main.go

# Staging
APP_ENV=staging go run main.go

# Production
APP_ENV=production go run main.go

Server starts on http://localhost:3020

Configuration Files

• config-base.yaml - Shared base configuration
• config-development.yaml - Development overrides
• config-staging.yaml - Staging overrides
• config-production.yaml - Production overrides

Pattern

1. Load base configuration
2. Load environment-specific overrides
3. Merge configurations
4. Start application

Benefits

• Single codebase for all environments
• Environment-specific settings
• Easy to add new environments
• Clear separation of concerns
