This project is a template for building web services using the Gin framework in Go. It provides a structured and scalable foundation for developing robust APIs.

• Modular Structure: Organized codebase for easy maintenance and scalability.
• RESTful API: Built-in support for creating RESTful endpoints.
• Database Integration: Pre-configured database layer for efficient data management.
• Caching: Integrated caching mechanism for improved performance.
• Error Handling: Standardized error handling and reporting.
• Middleware Support: Easy integration of custom middleware.
• Logging: Built-in logging for better debugging and monitoring.
• Graceful Shutdown: Ensures proper closure of resources and connections.
• Docker Support: Containerization ready for easy deployment.
• Tracing and Metrics: Integrated for better observability.

The application is configured using a YAML file located at config/config.yaml. Here's how to set it up:

1. Copy the config.yaml.example to config.yaml.

2. Edit the config.yaml file to set your specific configuration:

   server: port: 8080 timeout: 10s

   database: host: localhost port: 5432 user: youruser password: yourpassword dbname: yourdbname

   cache: address: localhost:6379 password: "" db: 0

   log: level: info format: json

   Adjust the values according to your environment and requirements.

1. Album Management: CRUD operations for managing albums.
2. Error Handling: Centralized error handling with custom error types.
3. Caching: Request caching to improve response times.
4. Database Integration: Configured database layer with connection pooling.
5. Middleware: Custom middleware for various purposes like error handling.
6. Logging: Structured logging for better traceability.
7. Graceful Shutdown: Proper shutdown procedure to ensure all resources are released.
8. Docker Support: Dockerized application for easy deployment and scaling.
9. Tracing and Metrics: Integrated tracing and metrics for monitoring and performance analysis.

1. Clone the repository
2. Configure the config.yaml file
3. Run go mod tidy to install dependencies
4. Run go run main.go to start the server

To start the server, follow these steps:

1. Ensure you have Go installed on your system.

2. Open a terminal and navigate to the project root directory.

3. Run the following command:

   go run main.go

4. You should see output similar to this:

   2023/06/10 15:30:45 Starting server on :8080

5. The server is now running and listening on port 8080 (or the port specified in your config.yaml).

You can now send requests to http://localhost:8080 to interact with the API.

To stop the server, press Ctrl+C in the terminal. The application will perform a graceful shutdown, ensuring all resources are properly released.
