The Adapter Pattern in Go - Structural Patterns

🔌 Adapter Design Pattern in Go — The Pattern That Saves Production Systems

"We can't change the legacy interface. But we need the new one live next sprint."

This is one of the most common constraints in production backend engineering — and the Adapter Pattern is how you solve it without risk.

In this video, we go deep on the Adapter Pattern from Go's standard library and real-world systems:
✅ Why you can't always modify existing interfaces — and why that's OK
✅ Build a PrinterAdapter from scratch using TDD (test-first approach)
✅ The Open/Closed Principle — Go's answer to backward compatibility
✅ http.HandlerFunc — the most elegant adapter in all of Go stdlib
✅ io.Pipe — bridging Reader to Writer using the Adapter pattern
✅ When to use Adapter vs Facade — and when neither is right
✅ How Go's implicit interface satisfaction makes adapters zero-ceremony
✅ Production patterns: middleware chains, retry adapters, transaction wrappers
