Rediscovering Angular Through Signals: A Beginner's Guide to Modern Frontend Frameworks

Every frontend framework is really answering the same question: when data changes, how does the UI keep up? Over the past decade or so, the answers—from React's useState to Vue's ref to Solid's signal—have been quietly converging on the same direction: fine-grained reactivity.

For many people, the word "Angular" still conjures up an image of NgModules everywhere and endless boilerplate. But Angular has become a different framework in recent years, and the core of that transformation is Signals.

This talk uses Signals as a mirror. We'll start by making sense of what modern frontend frameworks are actually thinking about: why "from data to UI" is such a deceptively hard problem, and how each framework has inched its way toward an answer. Then we'll get concrete and look at what Angular's Signals actually look like in practice (including the various new Signals syntax Angular has introduced).

Whether you're a frontend developer curious about where Angular stands today or someone weighing it for a technical decision, this talk aims to help you rediscover—through the lens of Signals—an Angular that's quite different from the one you remember.
