List of Golang Design Patterns based on Gang of Four (GoF).
Author understands that the implementation of design patterns in Golang can vary from place to place. In these examples, author is using these principles & building blocks:
- Following SOLID principles
- Maximizing usage of interface for abstractions instead of standard functions for easier mocks & testability
- Ensure a concrete folder structure to make it resemble real world usage
Author is using a real-world example in order to ease the reader in understanding the real-world usage of the design patterns. The real-world context used here is e-commerce industry.
| Pattern | Description | Example's Context |
|---|---|---|
| Decorator | Wrapping new behaviors on another behavior | Database and caching |
| Pattern | Description | Example's Context |
|---|---|---|
| Chain of Responsibility | Passing request along a chain of handlers | Checkout process |
| Strategy | Enables a family of algorithms to be selected at runtime and interchangeable | Get shipping rates from multiple shipping partners |
| Template Method | Defines a skeleton class which defers some methods to subclasses | Send sales report for multiple recipients (eg. Seller, Investor) |
