Using the Adapter Pattern in Laravel to Clean Up Payment Gateway Logic

A tutorial on DEV Community walks through applying the Adapter design pattern in Laravel to manage multiple payment gateways cleanly. The Adapter pattern is a structural design pattern that enables objects with incompatible interfaces to work together by translating one interface into another. The article first demonstrates a problematic approach where Stripe and Square payment logic is crammed directly into a controller using conditional statements. It then refactors the code by defining a shared interface and creating separate adapter classes for each payment provider. The result is a more maintainable, testable, and scalable architecture that separates business logic from controller responsibilities.
