arthurfp / Go_Builder_Pattern

An illustrative Go project demonstrating the Builder pattern with a practical example of building customizable pizzas. Features robust error handling and unit testing to showcase best practices in software design.

Builder Pattern Demonstration in Go

Overview

This repository demonstrates the use of the Builder design pattern implemented in Go. The project illustrates how to manage complex object construction with multiple optional configurations and showcases robust error handling within the builder processes. The primary focus is on building customizable pizzas, offering both standard and gourmet options.

Pattern Description

The Builder Pattern separates the construction of a complex object from its representation, allowing the same construction process to create different representations. This is particularly useful when an object requires multiple parts to be constructed across several steps or if its construction requires an extensive list of parameters. In this project, PizzaBuilder and GourmetPizzaBuilder are used to construct Pizza objects with various properties such as crust type, size, and toppings.

Project Structure

• cmd/: Contains the application entry point (main.go), demonstrating the use of the Builder pattern to construct pizzas.
• pkg/
  • builder/: Includes the interfaces and concrete implementations for the pizza builders.
  • product/: Contains the Pizza class definition.
  • config/: (Optional) Contains predefined configurations or recipes for building standard or gourmet pizzas.
