Understanding the Flyweight Design Pattern with go

Handling a large number of objects with shared properties can lead to memory consumption and performance issues in your applications. The Flyweight design pattern offers an efficient solution to minimize memory usage and improve performance by sharing the common parts among these objects.

In this post, we will explore the Flyweight pattern and demonstrate its implementation in Go using a shape drawing application example. The example will focus on creating and managing Circle objects with shared color properties, showcasing the pattern's ability to reduce memory consumption and simplify object management.

Go Implementation of the Flyweight Pattern

Throughout the post, we will walk you through a Go implementation of the Flyweight pattern, explaining key components such as the Shape interface, the Circle struct, and the ShapeFactory. We will discuss their roles in the pattern and demonstrate how they contribute to memory and performance optimization.

Expanding to Other Shapes

Although our example focuses on circles, the Flyweight pattern can be easily extended to other shapes or objects with shared properties. We will discuss how the Shape interface allows for seamless integration of additional shapes and how the pattern can be adapted to different use cases.
