Structural Design Patterns
In this chapter, we’ll dive into some of the most widely used structural design patterns and see how they apply in the world of Node.js. Structural patterns help us define clear relationships between components, enabling flexible and efficient architectures.
We’ll focus on three key patterns:
- Proxy: Control access to an object by standing in for it
- Decorator: Dynamically extend or modify an object’s behavior
- Adapter: Bridge incompatible interfaces to enable smooth collaboration
Along the way, we’ll also touch on reactive programming (RP) and explore Level, a fast, lightweight key-value store that fits well in the Node.js ecosystem. You’ll learn how to use it and even build your own plugin.
By the end of the chapter, you’ll not only understand how these structural patterns work but also know when and how to apply them effectively in real-world Node.js applications.
