If you write modern WordPress code, you've likely hit walls with tight coupling, global state, and hard-to-test classes. I just published a complete guide to using Dependency Injection in WordPress that changes how you structure plugins and themes.
This isn't about buzzwords. It's about making your code:
Easier to test without hacks
More flexible to adapt and scale
Clearer for collaborators and future you
You'll learn how DI helps you separate object creation from usage, reduce reliance on globals like $wpdb, and build systems that behave predictably under unit tests.
Whether you're refactoring old plugins or building complex sites, this guide gives you practical steps to embrace DI with real examples that work in WordPress today.
