Proxy Pattern in Go

Overview

This repository demonstrates the application of the Proxy design pattern in Go. The project highlights how to provide a surrogate or placeholder for another object to control access to it, showcasing flexibility and best practices in design patterns and unit testing.

Pattern Description

The Proxy pattern is used to provide a surrogate or placeholder for another object to control access to it. This pattern is useful in various scenarios such as lazy initialization, access control, logging, and more. In this project, we have implemented the Proxy pattern using a RealSubject and a Proxy to manage access to it.

Project Structure

• cmd/: Contains the application entry point (main.go), demonstrating the creation and usage of the proxy.
• pkg/proxy/: Houses the Proxy implementation.
  • subject.go: Defines the Subject interface.
  • real_subject.go: Implements the RealSubject.
  • proxy.go: Implements the Proxy to control access to the RealSubject.
  • real_subject_test.go: Unit tests for RealSubject.
  • proxy_test.go: Unit tests for Proxy.
