Throughout history, empires rise and fall. Throughtout web development, frameworks rise and fall. In 2026, we are firmly in ""late stage React"", where young devs can't remember the world any other way, and older devs are keeping their eye on the horizon for what's next.What if I told you there was a TypeScript-first UI framework created by a member of both the React _and_ Svelte core teams focused on fine-grained reactivity and rendering speed that will look instantly familiar to you?I'd like to introduce you to Ripple, show you around its syntax and philosophy and stimulate your mind out of the Present and into the Future.

It's easy to forget what the creators of React knew from the start: that React is not only for building web pages. Most of us have heard of React Native, that renders to native mobile components, but React doesn't have to render to "components" at all. There's React PDF to generate PDFs and Ink for building UI in the terminal.At my company, we've built a way for developers to use React to build plugins for our webapp that render to our custom components, giving us full control over the UI design (the "how"), whilst giving the plugin developer full control UX (the "what").In my talk, I'll explain what it's like to build a React renderer and reconciler, what they are and how to use them.I'd like to do a live demo showing how React can be used to convert html to markdown. And then I'd like to demonstrate how React can render to the Real World, by controlling IOT devices.
