Históricamente, Next.js ha tenido dos modos distintos de renderizado: Estático (para construir páginas prerenderizadas rápidas) y Dinámico (para mostrar datos frescos en tiempo de solicitud). Con el lanzamiento de la versión 16, Next.js ahora tiene un enfoque único llamado prerenderizado Parcial que ofrece lo mejor de ambos modos anteriores. En esta charla, Sam te mostrará cómo construir un Chatbot de IA moderno que aproveche las características más recientes de renderizado híbrido de Next.js, como las navegaciones instantáneas del lado del cliente a páginas renderizadas por el servidor.

Discussing the use of temporary client state, error handling, and the concept of optimistic rendering for responsive and instant applications in Next.js. Exploring features of Next 16, cache components, and the use cache directive for dynamic rendering and runtime prefetching in Next.js.

Historically, Next.js has had two distinct modes of rendering: Static (for building fast prerendered pages) and Dynamic (for showing fresh data at request-time). With the release of version 16, Next.js now has a single approach called Partial prerendering that offers the best of both previous modes. In this talk, Sam will show you how to build a modern AI Chatbot that takes advantage of Next.js’ newest hybrid rendering features, like instant client-side navigations to server-rendered pages.

La gestión del estado es fácil, hasta que no lo es. Claro, useState() está bien para la gestión de estado de componentes simples, literalmente para eso es. Pero a medida que nuestras aplicaciones de React crecen en complejidad, la inevitable larga cadena de useStates hace que sea más difícil entender y mantener la lógica de la aplicación, convirtiendo nuestros componentes en máquinas de Rube Goldberg.React 19 abre todo un nuevo mundo de patrones de gestión de estado que realmente tienen sentido para el estado local, compartido y global. En esta charla, pasaremos de usar useState() en todas partes a descubrir cómo los componentes del servidor, los parámetros de URL y más pueden hacer que la gestión del estado sea mucho más sencilla. También revisaremos hooks clásicos, aprenderemos sobre nuevos hooks y veremos cómo las bibliotecas de gestión de estado de terceros y las aplicaciones local-first pueden ser útiles.Digamos adiós (en su mayoría) a useState(), y hola a un futuro donde la gestión del estado no es solo una pila de setStates.

Adiós, useState

Hello, React Summit and goodbye, you states. Introduction of the speaker, David K. P., creator of Xstate library. Discussion on challenges with useEffect, managing multiple useEffects, implications of state overuse, optimizing state management in React, enhancing form data handling, effective state management strategies, innovative state management approaches, state management best practices, exploring state management options, promoting best practices, and exploring state management tools.

State management is easy, until it's not. Sure, useState() is fine for simple component state management – that's literally what it's for. But as our React apps grow in complexity, the inevitable long chain of useStates make it more difficult to understand and maintain app logic, turning our components into Rube Goldberg machines.React 19 opens up a whole new world of state management patterns that actually make sense for local, shared, and global state. In this talk, we'll transition from using useState() everywhere to discovering how server components, URL parameters, and more can make state management much simpler. We'll also revisit classic hooks, learn about new hooks, and see how 3rd-party state management libraries and local-first apps can be useful.Let's say goodbye (mostly) to useState(), and hello to a future where state management isn't just a stack of setStates.

Goodbye, useState

Renderizar una aplicación de React con renderizado del lado del servidor (SSR) puede sentirse agridulce: por un lado, SSR asegura una carga rápida de la página y un gran SEO al renderizar toda la página en el servidor, sin embargo, el cliente debe descargar e hidratar todos estos componentes para hacer la página interactiva. Para páginas con mucho contenido, esto puede llevar a una cantidad significativa de JavaScript siendo cargado y ejecutado, causando tiempos de interacción más lentos y problemas de rendimiento importantes.  En Wix, enfrentamos un desafío significativo: ¿cómo podríamos ofrecer tiempos de interacción rapidísimos mientras evitamos el cuello de botella de rendimiento de descargar e hidratar cada componente renderizado por SSR en el cliente? Durante mucho tiempo, esto se sintió como un problema insoluble, hasta que la nueva API de Suspense cambió el juego. En esta charla, compartiré la historia de cómo abordamos este problema de frente, aprovechando la nueva API de Suspense introducida en React 18 para cargar e hidratar dinámicamente los componentes de React solo cuando entran en el viewport. Aunque las capacidades de renderizado basadas en promesas de Suspense no están ampliamente documentadas, demostraron ser la herramienta revolucionaria que necesitábamos para liberarnos de las limitaciones de la hidratación tradicional y mejorar el rendimiento de millones de sitios web de Wix. ¡Prepárate para una inmersión técnica profunda con muchos ejemplos de código que te equiparán para abordar los desafíos de hidratación y mejorar el rendimiento de React!

Ganando la Batalla de Hidratación: Desbloqueando el Rendimiento de React con el Poder de Suspense

Challenges of SSR with React hydration and its impact on interactivity and performance are outlined. The importance of selective hydration, efficient component loading, promise handling, lazy loading, and real-world impact are highlighted. Selective hydration enhances performance by reducing JS load, comparing server components with Suspense, and introducing React 19 optimizations. React 19 brings cleaner promise-based behavior, selective hydration improvements, and key takeaways on SSR benefits, suspense power, and React 19 enhancements.

Rendering a React app with server-side rendering (SSR) can feel bittersweet - on one hand, SSR ensures fast page load and great SEO by rendering the entire page on the server, however the client must download and hydrate all these components to make the page interactive. For pages with lots of content, this can lead to a significant amount of JavaScript being loaded and executed, causing slower interaction times and major performance issues.  At Wix, we faced a significant challenge: how could we deliver blazing-fast interaction times while avoiding the performance bottleneck of downloading and hydrating every SSR-rendered component on the client? For a long time, this felt like an unsolvable problem - until the new Suspense API changed the game. In this talk, I’ll share the story of how we tackled this problem head-on, leveraging the new Suspense API introduced in React 18 to dynamically load and hydrate React components only when they enter the viewport. While Suspense's promise-based rendering capabilities aren’t widely documented, they proved to be the game-changing tool we needed to break free from the limitations of traditional hydration and improve the performance of millions Wix websites. Prepare for a technical deep dive with lots of code examples that will equip you to tackle hydration challenges and boost React performance!

Es fácil olvidar lo que los creadores de React sabían desde el principio: que React no es solo para construir páginas web. La mayoría de nosotros hemos oído hablar de React Native, que renderiza a componentes móviles nativos, pero React no tiene que renderizar a "componentes" en absoluto. Existe React PDF para generar PDFs e Ink para construir interfaces de usuario en el terminal.En mi empresa, hemos desarrollado una forma para que los desarrolladores usen React para crear plugins para nuestra aplicación web que se renderizan en nuestros componentes personalizados, dándonos control total sobre el diseño de la interfaz de usuario (el "cómo"), mientras que el desarrollador del plugin tiene control total sobre la experiencia de usuario (el "qué").En mi charla, explicaré cómo es construir un renderer y reconciler de React, qué son y cómo usarlos.Me gustaría hacer una demostración en vivo mostrando cómo React se puede usar para convertir html a markdown. Y luego me gustaría demostrar cómo React puede renderizar al mundo real, controlando dispositivos IOT.

React Beyond the DOM

Eric Rasmussen discusses React beyond the DOM, React PDF, Ink tools, and rendering to Markdown. The overview includes React Reconciler, host configuration, state management with real-world entities like light bulbs, and building a traffic light state machine visually. The talk also covers securing third-party JavaScript, expanding React rendering possibilities, advanced tooling for state machines, controlling light bulbs via renderer callbacks, server functions for fetch in the cloud, and potential robot programming with React.

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.

GPT5 es un mejor programador frontend que yo, y Cerebras Code es un programador 10 veces más rápido que yo. Pero "generative UI" todavía está mayormente atrapado en un paradigma de llamar widgets prediseñados. Los nuevos modelos, rápidos y orientados a la codificación, crean nuevas oportunidades para crear experiencias verdaderamente personales y personalizadas, sin la preocupación de que las personas quieran que sus aplicaciones se mantengan estables y confiables.

Generative UI Más Allá de Llamar Componentes Prediseñados

Failed generative UI talk explanation, exploring beyond text display with React. Vercel's generative UI tool calling. Demo challenges due to CloudFlare, GPT-5 differences. Interactive artifact generation, AI News newsletter, and ChachiBT concept. Unique superpower of developers: modifying UI for needs, tool generation challenges, pair programming concept to understand codebase better, importance of human involvement in coding, control in developer experience. Importance of control in developer experience, negative impact of AI autonomy, illusion of productivity in Vibe coding apps. Combining human and AI attention, interactive planning for coding agents, parallelizable collaborative planning. Non-interactive limitations, good interactive planning, async value of depth analytics. Increased flow disruption, semi-async failure-death, focus on code-based understanding. Hierarchical code maps for better code understanding and prompt engineering. Interplay between human and AI in code control, enhancing coding ability, and investing in coding skills. Illustrating the constant human-AI interaction and the cost of syncing with AI for different modalities. Discussing the cost of multi-modality sync with AI, encouraging a balanced approach to leveraging AI for productivity. Discussing the importance of user-friendly interfaces and the potential future of generative UI. Discussing the future of user-controlled dashboard creation and the shift of power from designers to users in generative UI development. Discussing the evolution of frameworks from developer-centric to user-centric for creating customizable UIs and the concept of malleable software coined by Jeffrey Lait. Pushing for industry adoption of the Codemap concept to enhance code quality and readability, exploring its usage with WinSurf and potential new dev tools enabled by a shared language for interacting with code bases. Discussing the impact of project size on AI effectiveness, emphasizing the importance of breaking down problems and utilizing code maps for better code management and context understanding. Discussing the importance of code map guidance and keeping code maps up to date in fast-moving projects through regular refreshing and regeneration based on git commits.

GPT5 is a better frontend coder than me, and Cerebras Code is a 10x faster coder than me. But "generative UI" is mostly still stuck in a paradigm of function calling premade widgets. New, fast, coding oriented models create new opportunities for creating truly personal, customized experiences, without the offsetting concern that people want their apps to stay stable and reliable.
