Have you ever wondered how React Query works under the hood? What magic does it use to be so fast and responsive? How to write your own implementation and get better at writing such libraries? You’ve come to the right place!

In this talk, we are going to dive into how React Query works, how it handles caching, how it manages multiple requests at the same time without wasting network resources, and how it works cross-framework without needing to rewrite its core components.

This talk is intended for experienced developers and assumes that you’ve used React Query in the past, and are familiar with concepts such as custom hooks, pub-sub mechanism, React data-syncing patterns, and a little bit about caching and promises.
