Angular CDK (Component Dev Kit) provides behavior primitives for building accessible, high-quality UI components without prescribing visual styling. As the creator of CoreUI with 12 years of Angular development experience, I’ve used CDK in applications serving millions of users to build custom drag-drop interfaces, overlays, and virtual scrolling that reduced development time by 50% compared to implementing from scratch.

The most effective approach uses CDK modules for specific behaviors like drag-drop and overlays.
