Most "generative UI" today is little more than glorified tool calling of premade components. Most people are not willing to experiment with truly generated experiences on the fly out of a fear of lack of familiarity and not wanting to create unreliable/unstable UIs for users. This is a skill issue. Let me show you how.

Traditional chat interfaces only return text, but what if your AI assistant could render custom React components directly in the conversation? In this lightning talk, we’ll explore generative UI - where chat applications stream contextually appropriate React components instead of plain text responses. When users ask about sales data, they get interactive charts. When they search for properties, they get rich product cards.

We keep hearing that React Server Components (RSC) are the future. And that they're supposed to be the best for performance. And just the best in general. But how valid is that claim?

Getting to a production-ready React application is about more than just choosing a framework. To ship features efficiently, developers need a reliable pipeline that can handle everything, from linting to bundling, as quickly and accurately as possible.In this talk, we will explore how modern tools like Rolldown and Oxc can speed up your development workflow, how they can help in your project today and what is planned for the future.

Much like the promise of cake in Portal, login forms are everywhere in web development. While they may seem functional at first glance, many users with disabilities encounter a maze of invisible walls, from keyboard traps to inaccessible CAPTCHAs. It's as if GLaDOS designed these forms herself to test us!In this practical session, we will debug the accessibility issues of a real React login component live, similar to traversing those test chambers: Using an actual screen reader, we'll show how minor improvements, such as proper ARIA implementation and effective focus management, can transform a complex test chamber into a smooth user experience. Additionally, we will address the common pitfalls that GLaDOS might throw at us in both the Portal universe and the real world of accessibility, especially concerning authentication processes and its special needs as written down in the WCAG.

A case study explores the Streaming company's journey of building automated testing layers within a complex, multidimensional React monorepo and achieving quality contribution feedback within minutes.

Ever wondered how React Native DevTools work under the hood? I went down the rabbit hole, reverse-engineered the whole thing, and figured out how to inject custom code - no forks, just a bit of hackery. In this talk, I’ll walk you through the journey: how the DevTools architecture works, how I hooked into it cleanly, and how that led to building a framework for writing your own plugins, complete with React-based UIs and sandboxed execution. Let’s make DevTools truly extensible.

In this hands-on talk, I’ll build a simple app for iOS, Android, and the web—then monetize all three platforms in just 20 minutes. Using React Native, Expo, and RevenueCat, I’ll demonstrate how easy it is to create monetized apps today.

TypeScript has a very unique type system that is universally loved. Yet, most developers have only scratched the surface on what unique things are possible using Typescript's types.For example, are you familiar with the `infer` keyword? How about recursive types? Did you know that 0 can be a type?

Which state library is the right choice for your app – Redux, MobX, Zustand, Jotai, or no state manager at all? In this talk, we’ll compare them using real metrics in a realistic data-heavy app that visualises large datasets with live data charts and 3D rendering.

SSR, Core Web Vitals, and accessibility sound familiar? If you're struggling with these aspects of web development, you're not alone!But what if the key to tackling them was already open on your screen? Yes, Chrome DevTools can be your best friend!In this talk, we'll dive into practical ways to use your favourite browser to find performance issues, fix tricky accessibility mistakes, and improve those Web Vitals scores.Learn how to turn DevTools insights into tangible improvements. Are you ready to make your browser your next teammate?See you there!

Micro Frontends are one of the tools to ensure scalability in large-scale applications. To properly use micro frontends some of the key properties of a monolith need to be given up. This can result in severe drawbacks that are especially visible in regulated industries such as healthcare.In this talk we'll look at a large-scale web application that was developed for one of the world's leading medical technology suppliers. In particular, we investigate how the project managed to use best practices of both, the centralized and distributed computing area, to be scalable yet fully compliant to regulatory aspects.

Discover the power of Server Components in React without the need for a framework. In this talk, we will explore how to build a simple server-side rendering solution using "only" vanilla JavaScript and Node.js. We'll dive into the core concepts of Server Components, including how to render components on the server abd manage data fetching. By the end of this session, you'll have an understanding of how to implement Server Components in your own projects without relying on a framework.

Master real-time communication in React and React Native! We'll explore WebSockets, WebRTC, and the future with WebTransport to build highly interactive, live applications across web and mobile platforms.

3D on the web is no longer just about fancy tech demos — it’s now used to build high-quality tools, visualizations, games, and immersive experiences. In this talk, we’ll explore why, what, and how to build production-ready 3D web apps with React in 2025 — and whether AI can help. What we’ll cover:A quick history of 3D on the webThe current state of the React Three ecosystemGetting started live by building a XR react appThe role AI can play in building 3D experiencesWhy 3D is becoming a frontier for expressing your creative and engineering skillsWhether you're just curious about 3D or already building apps with the React Three ecosystem, this talk will show you what’s coming, what’s already possible — and how to get started with React and 3D.

AI is no longer just a tool — it's becoming part of the team. In this talk, we'll explore how LLMs are unlocking new collaboration patterns across design, product, and engineering. You'll see real examples of AI-powered workflows for building frontend applications, from design-to-code automation to role-based updates without writing code. Learn how teams are shipping faster by shifting tedious tasks to agents and enabling more connected, iterative development.

I will go in depth describing a brand new integration of React Native into Unreal Engine. Gaming has long been lagging behind mobile and web in the ease of building a good UI , especially for data heavy games. The gaming world has long embraced the idea of web - games like Civilization 7 launch with fully Web UI by embedding a specialized browser. I think React & React Native are a great fit for revolutionizing how game UI are built.

React’s styling landscape is evolving fast. With Server Components, Tailwind v4, and the next era of CSS standards, our old habits need an upgrade. In this talk, we’ll put CSS Modules, Tailwind CSS, and CSS-in-JS to the test against real-world demands like server-side rendering, streaming UI, scalable theming, and runtime performance. You’ll learn how styling choices impact payload size, async behavior, and design system consistency at scale.

A few lines of code and UI theme will follow any colour that you want. Do you want it? Explore the OKLCH colour space for creating dynamic themes! This colour model ensures better a11y, predictable color transformations and supports the wide-gamut P3 colors.

Let's talk about real-world strategies to integrate accessibility testing into your React workflow — without slowing down your team. From axe-core to CI pipelines, we’ll cover how to go from reactive fixes to proactive accessibility.

This talk explores how to transform React components into standards-based Web Components, unlocking the ability to share UI elements across Angular, Vue, Svelte, and even vanilla JavaScript applications. While frameworks like Angular and Vue offer native support for this kind of interoperability, React doesn't – at least, not out of the box.This talk demystifies how to achieve similar results in React using supported patterns and tooling. By bridging the gap between React and the Web Components standard, we can promote true component reusability, reduce duplication, and simplify integration in micro frontends and design systems. Attendees will learn practical techniques, tooling options, and real-world benefits of this powerful architectural strategy.

By treating documentation as React building blocks, we can generate a one‑page README, an interactive API reference, or a fully branded design‑system site from the same source of truth.The result is always‑accurate API documentation, MDX pages, and interactive examples that stay updated every time you push code, no more stale documentation or forgotten types. I’ll show how React Server Components fits perfectly into making it easy to have accurate, up-to-date documentation as extensible as any UI.

Astro islands are a powerful primitive that allow you to take your statically rendered content, and gradually add interactive components as you go. Discover what client directives can do, when to use them, and how to communicate state between your islands effectively.

We're an industry that solves impossible technical challenges, builds systems serving billions, and automates the world - yet we haven't figured out how to sit at a desk without destroying our bodies. I learned this the hard way: active engineer → COVID couch potato → 41-year-old developer with chronic pain. The research reveals I was just one predictable data point in a massive pattern.This isn't about being "out of shape." Within hours of sitting, arteries lose elasticity and blood pressure spikes. After one day, insulin dysfunction kicks in.
