React Advanced

React Advanced 2025

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.
