Three days by the sea
Here's what we enjoyed at the last edition. The full programme for 2027 will be announced in April.

"No one uses what I built!" "Why can't I get support to do this?" "I don't even know why we're using that?" "Why am I always the one doing everything?" Sound familiar? The truth is, friction is ever-present in our careers — in our influence, processes, relationships, and even the code we ship. But we're rarely taught how to handle it. Here's the fun fact: React's history is full of lessons in dealing with friction. From the early skepticism around JSX and the Virtual DOM to the chaos of Server Components, the React team has navigated many friction points you'll face: skeptical stakeholders, unclear messaging, delayed initiatives, and the challenge of getting buy-in. So let's recap the highlights since its birth to the latest release, understand what React got right (and wrong), and extract practical takeaways you can apply to your career, team, and developer experience initiatives. Whether you're leading a team, building internal tools, or advocating for a technical decision, you'll leave with concrete strategies for driving change, building trust, and shipping initiatives that actually get adopted.

Not long ago, starting a Node.js project meant installing lots of packages just to handle environment variables, run tests, or use TypeScript. Now, those days are behind us, and 2026 is the time to make the switch. Node.js is stronger than ever, but there’s still a big issue: many people keep using outdated versions with known security problems. We need to discuss the current LTS schedule and why you should switch to Node 26. This session will cover both the roadmap and hands-on examples. You’ll see how much you can do with just Node.js and your chosen framework, often with far fewer extra packages. We’ll look at built-in TypeScript support that works right away, so you can write and run TypeScript without a build step. We’ll also cover testing with node:test and node:assert, built-in .env configuration, and native fetch powered by Undici for HTTP. Other topics include watch mode for development, node:sqlite for embedded databases, and the stable Permission System for better security.

For decades, we've optimized code to be read by humans — naming conventions, file structure, abstractions, documentation. All of it shaped by what helps a person understand the code and make changes safely. Now more and more code is written, reviewed, and navigated by AI, which doesn't have the same strengths or weaknesses we do. This talk asks what good architecture looks like in the AI era, in a way that sets AI up to succeed. I'll share what we've learned leading this shift at Buffer — which traditional principles still hold, which need rethinking, and how to approach this transformation in an existing codebase.

Following years of converging, the native platforms look drastically different again – it’s time to leverage the biggest strength of React Native and make our users happier at the same time. Instead of limiting ourselves to the lowest common denominator, this talk explains why and how to leverage the underlying platforms’ native components and APIs to build a better, faster and more accessible app. It explores the differences between the iOS and Android platform SDKs, how the more recent SwiftUI and Jetpack Compose frameworks are a great but underutilized fit for React Native due to shared paradigm, and finally how to tap into them using either Nitro or Expo Modules.


Frontend and backend are often treated as opposite worlds. But are they really? Modern frontend apps face many of the same challenges as backend systems: multiple tabs drifting out of sync, shared cache invalidation, coordinating a single source of truth, retries, optimistic updates, and stale data. In this talk, we’ll look at how everyday UI code increasingly becomes a coordination problem, and what we can learn from backend thinking to handle it better.

Video games! Now that I have your attention: yes, you can build real 3D games with the same React you use to render dropdowns and settings pages. To prove it, we'll build Arkanoid, the brick-breaking arcade classic, using React Three Fiber. Along the way we'll cover meshes, lights, and cameras, physics with Rapier and the postprocessing that makes everything glow. React can really do everything!

Streams are an excellent abstraction for handling real time events, and streaming data such as audio and LLM responses. This talk takes you through the key APIs of web streams, and provides some examples for how you can use them in your applications.

Throughout history, empires rise and fall. Throughout 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.

From UI state to data-loading, React developers have plenty of solutions for managing client-side state. But what happens when a user action kicks off a process that takes hours or days to complete? Where does that state live, and how does your UI stay connected to it? A new wave of durable execution solutions is addressing exactly this: backend processes that persist long-running state, retry on failures, and survive continuous deployments without interruption. Built on lessons from Navion, an AI-native logistics company, this talk shows how React and Temporal work together in production to coordinate the automation and human oversight of thousands of delivery orders. I'll demonstrate how React 19's server features wire directly to workflows by querying their state, sending data and commands to running processes, and surfacing errors to users. The benefits of durable execution will become clear and you'll take away a practical understanding of when to use its power and how to wire it into your React application.
