Preact Signals and the Signalize Gem

What are signals? What is find-grained reactivity? Why is everyone talking about them on the frontend these days? And what, if anything, can we apply from our newfound knowledge of signals to backend programming? Is it possible to use signals in Ruby? (Yes!) Learn all about signals, the Preact Signals library, and the new Signalize gem right here in the latest episode of Fullstack Ruby.Links:
