Angular 19 - Introduction to linkedSignal

Angular 19 introduces the linkedSignal primitive, revolutionizing reactive programming. Linked signals are writable and automatically update based on source signals, addressing the limitations of computed signals in reset patterns. LinkedSignal's "source and computation" overload allows custom calculations based on source signals, while the shorthand syntax simplifies common scenarios. It enables explicit value setting while ensuring automatic updates. Linked signals offer simplified reset patterns, enhanced flexibility, improved performance, and cleaner code, making them an essential tool for handling complex reactive scenarios. They combine the benefits of computed and writable signals, providing a robust solution for data consistency and user experience. The linkedSignal primitive empowers Angular developers to create more responsive and user-friendly applications, simplifying signal management and ensuring seamless synchronization between reactive components.
