The Bigger Picture
Explore how six core design patterns in Node.js work together to provide structure, flexibility, and clarity to your code. This lesson helps you understand how to centralize creation, extend functionality without altering core logic, and isolate algorithms, preparing you to build maintainable and scalable backend systems.

We’ve worked through six patterns that form the backbone of structural design in Node.js. Each one solves a specific kind of design tension—but together, they express the same goal: to make change easy by containing it.
Here’s how they fit in the bigger picture:
Factory: Centralizes creation and hides complexity, applying Dependency Inversion and Open/Closed so new variants plug in without touching existing code. ...
