Angular Signals Force a Paradigm Shift in Component-Driven Development

Angular's move to signal-based reactivity fundamentally challenges the core assumption of component development tools like Storybook: that components are pure functions of static input properties. The technical shift from plain properties to InputSignal objects—demonstrated through real issues in ng-prism—cannot be solved by tool patches alone; it demands complete architectural redesign. This signals a broader industry movement toward fine-grained reactivity, and the entire ecosystem of component development tools will need fundamental rethinking to remain relevant.
