Since the creation of front-end frameworks, a major challenge has always been change detection, facilitating the refreshing of the view with maximum performance.

Since its inception, Angular has relied on Zone.js, a library that patches native JavaScript APIs, to perform event-based change detection. Since Angular version 1, 19 versions have passed, and a new way of thinking about change detection has emerged. This emergence has appeared with the arrival of Signals (a new primitive reactivity system in the framework) to the point of no longer speaking of change detection but of synchronization.

What is synchronization? How to integrate Signals optimally to have the best performance of it? What are the best practices to implement and the pitfalls to avoid? And finally, how to achieve a so-called smooth migration to this new system?

This talk aims to provide you with these answers through concrete cases that I have implemented in various projects, examples, and content slides ;)
