Popular eCommerce Design Patterns

Design patterns are meant to help the developers solve common design problems on their eStore. There’s no one perfect eCommerce design pattern, each with its own uses and more.

MVC Pattern

The Model-View-Controller (MVC) pattern is a popular architectural design pattern that’s widely used in eCommerce development. It separates the application into three distinct components.

Model

• Represents the data and business logic of the application. It handles data storage, retrieval, and validation.
• In an eCommerce context, the Model might include product information, customer data, order details, and shopping cart functionality.

View

• Responsible for the visual representation of the data. It’s the user interface that displays information to the customer.
• In eCommerce, Views could be product pages, category listings, shopping carts, and checkout pages.

Controller

• Acts as the intermediary between the Model and View.
• It handles user interactions, updates the Model with user input, and determines which View to display based on the current state of the application.
• In an eCommerce setting, the Controller might handle actions like adding products to the cart, processing payments, and managing user authentication.

Example of MVC Pattern in eCommerce

1. A user clicks on a product to view its details.
2. The Controller receives the user’s request and retrieves the product information from the Model.
3. The Controller then passes the product data to the View, which displays the product details on the page.
4. If the user adds the product to their cart, the Controller updates the Model to reflect the change and redirects the user to the shopping cart page.

By adopting the MVC pattern, eCommerce websites can benefit from a more organized, scalable, and maintainable architecture.

Function Chains

Function chains are a design pattern that combines multiple functions or operations into a single, sequential chain. This pattern can be particularly useful in eCommerce applications where complex workflows involve multiple steps. The tasks include processing orders, handling user authentication, and more.

How Do Function Chains Work?

1. Define Functions: Each individual step in the workflow is defined as a separate function. These functions can take input parameters and return output values.
2. Create the Chain: The functions are linked together to form a chain. Each function’s output becomes the input for the next function in the chain.
3. Execute the Chain: When the chain is executed, the input data flows through each function in the specified order. The final output is the result of the entire workflow.

Example of a Function Chain in eCommerce

1. Validate order information: Check if all required fields are filled out correctly.
2. Calculate shipping costs: Determine the shipping cost based on the shipping address and product weight.
3. Process payment: Verify payment information and charge the customer’s card.
4. Generate order confirmation: Send an email to the customer with order details and a receipt.

By using a function chain to represent this workflow, the code becomes more organized and easier to maintain.

Strategy Patterns

The Strategy Pattern is a behavioral design pattern that provides a way to encapsulate algorithms and make them interchangeable at runtime.

This pattern is particularly useful in eCommerce applications where different algorithms or strategies can be used to perform the same task. These include calculating shipping costs, applying discounts, or recommending products.

How Do the Strategy Patterns Work?

1. Define an Interface: Create an interface that defines the common methods or operations that all strategies must implement.
2. Implement Concrete Strategies: Create concrete classes that implement the interface, each representing a different algorithm or strategy.
3. Use a Context Class: Create a context class that holds a reference to a strategy object. The context class can use the strategy object to perform the desired operation.

Example of the Strategy Pattern in eCommerce

Calculating shipping costs:

• The Context class could be a Product class.
• The Strategy interface could define a calculateShippingCost() method.
• Concrete strategies could include StandardShipping, ExpressShipping, and InternationalShipping.
• The Product class can use different shipping strategies based on the customer’s location or the product’s weight.

With the Strategy Pattern, eCommerce applications can become more flexible and adaptable to changing business requirements.

API Interfaces

API (Application Programming Interface) interfaces are fundamental design patterns that define the contracts between different components of an eCommerce application. They provide a well-defined way for components to interact with each other, promoting modularity, reusability, and maintainability.

Key Components of API Interfaces

• Endpoints: The specific URLs or methods that components can use to interact with the API.
• Requests: The data or parameters that are sent to the API.
• Responses: The data or information that the API returns in response to a request.
• Data Formats: The format in which data is exchanged, such as JSON or XML.

Example of an API Interface in eCommerce

Product API:

• getProductById(productId): Retrieves a product by its ID.
• getProductsByCategory(categoryId): Retrieves products belonging to a specific category.
• createProduct(productData): Creates a new product.
• updateProduct(productId, productData): Updates an existing product.

With well-defined API interfaces, eCommerce applications can become more modular, scalable, and maintainable.

Ambassador Pattern

The Ambassador Pattern is a design pattern that acts as a gateway or intermediary between different systems or components within an application. In eCommerce, it can be used to simplify communication with external services like payment gateways, shipping providers, or third-party APIs.

Key Components of the Ambassador Pattern

• Ambassador: The intermediary component that handles communication between the systems.
• Client: The system that sends requests to the Ambassador.
• Target System: The system that receives requests from the Ambassador.

Example of the Ambassador Pattern in eCommerce

Payment Gateway Integration:

• The Ambassador could be a component that handles communication with the payment gateway.
• The client could be the eCommerce application.
• The target could be the payment gateway.
• The Ambassador could handle tasks like encrypting payment data, validating payment information, and processing payments.

This pattern provides a centralized point of control for communication, making it easier to manage and maintain the application’s architecture.

Decorator Pattern

The Decorator Pattern is a structural design pattern that allows you to add new behavior to objects dynamically, without modifying their existing code. This is particularly useful in eCommerce applications where you need to customize products or services with additional features or options.

Key Components of the Decorator Pattern

• Component: The base interface that defines the common behavior for all objects.
• ConcreteComponent: The base implementation of the Component interface.
• Decorator: An abstract class or interface that implements the Component interface and wraps around a ConcreteComponent.
• ConcreteDecorator: Specific implementations of the Decorator that add new behavior to the wrapped ConcreteComponent.

Example of the Decorator Pattern in eCommerce

Product Customization:

• The Component interface could define methods like getPrice() and getDescription().
• The ConcreteComponent could be a Product class.
• Decorators could include GiftWrappingDecorator, WarrantyDecorator, and DiscountDecorator.
• A product can be customized with multiple decorators to add different features and options.

With this design pattern, you can create custom products or services without modifying their core functionality. That makes it easier to add new features or promotions.

Factory Pattern

The Factory Pattern is a creational design pattern that provides a way to create objects without specifying their exact class. This is particularly useful in eCommerce applications where the type of object to be created may depend on various factors, such as user input, configuration settings, or external data.

Key Components of the Factory Pattern

• Factory Interface: Defines the interface that all factories must implement.
• ConcreteFactory: Specific implementations of the Factory interface that create different types of objects.
• Product: The interface or abstract class that defines the common behavior for all objects created by the factory.
• ConcreteProduct: Specific implementations of the Product interface that represent different types of objects.

Example of the Factory Pattern in eCommerce

Product Creation:

• The Factory interface could define a createProduct() method.
• Concrete factories could include PhysicalProductFactory, DigitalProductFactory, and SubscriptionProductFactory.
• The Factory pattern can be used to create different types of products based on user input or configuration settings.

With this eCommerce design pattern, you can create different types of objects dynamically, without modifying the code that uses them. This can make the application more maintainable and easier to extend.

Strangler Pattern

The Strangler Pattern is a design pattern that provides a strategy for gradually replacing a legacy system with a new one without disrupting the existing functionality. This is particularly useful in eCommerce applications where it’s necessary to modernize the system without causing downtime or data loss.

Key Components of the Strangler Pattern

• Legacy System: The existing system that needs to be replaced.
• New System: The new system that will replace the legacy system.
• Facade: A layer that acts as a gateway between the client and the legacy or new system.

Example of the Strangler Pattern in eCommerce

Migrating from a legacy eCommerce platform to a modern one:

• The legacy system could be a custom-built platform.
• The new system could be a popular eCommerce platform like Magento or Shopify.
• The facade could handle requests from the client and route them to the appropriate system based on specific criteria.

This approach can help reduce the risk of migration, improve scalability, and enhance the overall flexibility of the application.
