A simple RESTful API project built with Gin, designed as a playground for learning modern Go web development concepts such as routing, middleware, database integration, and OAuth2 login.

• RESTful API with CRUD support
• PostgreSQL integration using GORM
• Google OAuth2 login
• Environment-based configuration (via viper)
• Clean project structure with separation of concerns
• Elastic Beanstalk-ready deployment

• Go 1.21+
• Gin framework
• PostgreSQL
• GORM ORM
• Viper (config)
• OAuth2 (Google login)
• Elastic Beanstalk (deployment)

Create a .env file to populate environment variables:

APP_PORT=8080 #5000 production

DB_HOST=localhost
DB_PORT=5432
DB_USER=postgres
DB_PASSWORD=yourpassword
DB_NAME=tasks
SSL_MODE=disable

GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-client-secret
GOOGLE_REDIRECT_URL=your-google-redirect-url

JWT_SALT_KEY=
FE_ORIGINAL_URL=

Then set up config.yaml (already in repo)

go mod tidy

go run database/migrations/migration.go

go run main.go

eb init -p go go-gin-dev
eb create go-gin-dev
eb deploy
