golang-gin-database — Database Integration

Integrate PostgreSQL with Gin APIs using the repository pattern. Keeps database logic out of handlers and services, and supports swapping GORM ↔ sqlx without touching business logic.

When to Use

• Adding a PostgreSQL database to a Gin project
• Implementing the repository pattern (interface + concrete implementation)
• Writing GORM or sqlx queries
• Setting up database connection pooling
• Running migrations (golang-migrate)
• Wiring repositories → services → handlers in main.go
• Writing context-propagating transactions
