Open-Closed Workshop

In this workshop, we'll focus exclusively on the open-closed principle (the O in SOLID). Using real-life code, line by line, we'll refactor a confusing class into something far more manageable and extendable. Once finished, we'll have gained the luxury of introducing new functionality, not by modifying existing code, but by instead writing a new class.

• What We Are Refactoring
• Low-Hanging Refactors
• Remove Conditionals and Embrace the Pipeline
• Extract What Changes into a Service Provider
• Discussing Responsibility
