Si tuvieras los mismos objetivos que React Compiler, ¿qué tipo de componente de React escribirías? En esta masterclass Tony y la audiencia imaginan que son React Compiler, reescribiendo un componente de React de la misma manera exacta en que lo hace el compilador. A lo largo del camino, obtendremos una comprensión más profunda de los internos de React, para comprender completamente cómo funciona el compilador, por qué funciona de esa manera y cómo decidir si deberías usarlo.

If You Were a React Compiler

In this talk, the speaker aims to build an accurate understanding of how the new React compiler works, focusing on minimizing re-renders and improving performance. They discuss the concept of memoization and how it can be used to optimize React applications by storing the results of function calls. The React compiler automates this process by analyzing code, checking dependencies, and transpiling JSX. The speaker emphasizes the importance of being aware of memory concerns when using memoization and explains how the React compiler detects changes in function closure values. They also mention the Fibre Tree, which drives the reconciliation process and helps optimize performance in React. Additionally, the speaker touches on JSX transpilation, compiler caching, and the generation of code. They encourage developers to understand the code generated by the compiler to optimize specific sections as needed.

If you had the same goals as React Compiler, what kind of React component would you write? In this talk Tony and the audience imagine they are React Compiler, rewriting a React component in the exact same way the compiler does. Along the way, we'll gain a deeper insight into React internals, to fully grasp how the compiler works, why it works that way, and how to decide if you should use it.

Aprovechando reactjs para crear microfrontends reutilizables abordando desafíos y errores comunes.

React y Microfrontends

I'm thrilled to be here at the React Summit to talk about React and Microfrontends. Micro frontends allow reusable components to be shared across the organization and are consumed at runtime using webpack's module federation feature. The module federation plugin enables sharing dependencies with unknown components. Micro frontends can be configured with Webpack by chunking and specifying shared dependencies. When rendering web components from a remote, it's best practice to import them using react lazy or loadable. When deciding between micro frontends and npm packages, consider the reusability at build time or runtime. Setting up micro frontend development involves installing the necessary libraries and deciding on eagerly or lazily sharing dependencies. Splitting monolithic content into microcontent requires considering independence and avoiding page awareness. Microcontent should be consistent and encapsulated using tools like emotion. Scaling and versioning microcontents is important for deployment at scale. Communication between microcontents can be done using React's one-way data binding. Shadow DOM can be used for encapsulation, but it has challenges with styling and accessibility. Developer mindset and clear documentation are crucial for consistency and communication in microfrontend development.

Leveraging reactjs to create reusable microfrontends addressing challenges and common pitfalls.

¿Alguna vez te has preguntado cómo React puede "actualizar" una página mientras aún se está cargando? Nos hemos perdido tanto en la discusión de cosas como Next.js, Suspense, Signals, Server Components y Server Actions, que la mayoría de los desarrolladores de React han pasado por alto una de las piezas más recientes de magia de React: Out Of Order Streaming.

Out Of Order Streaming (El Secreto que Impulsa el React Moderno)

I'm the second-best TypeScript YouTuber. I'm giving a talk on streaming in React and the benefits it brings to applications. Streaming allows for faster perceived loading times by sending partial HTML to the browser, rendering it and waiting for the rest to complete. Server-side loading can cause delays, but this can be improved by caching HTML on a CDN. Streaming HTML in a different order has been a challenge, but there are JavaScript solutions. Optimizing HTML streaming with Suspense and dynamic I.O. can further improve loading times. Using suspense in client-side rendering and addressing challenges with Next.js React model are interesting patterns. Caching can now be done at a more granular level, improving SEO and reducing load on the host server. Rendering on the server is not a big penalty compared to multiple API requests. Thank you all.

Ever wonder how React can "update" a page while it's still loading? We've gotten so lost in the discussion of things like Next.js, Suspense, Signals, Server Components, and Server Actions, that most React devs have totally missed one of React's most recent pieces of magic: Out Of Order Streaming.

Welcome to this workshop on mastering React Server components and React Server actions. We'll be using Next.js as our runtime server. We'll explore the difference between client components and server components, how to do updates and query server resources using server components and actions. React Server components render on the server, eliminating REST call overhead and simplifying working with data. They also provide advantages such as secure access to server APIs and databases. React Server components use a two-step flow of rendering on the server and merging the JSON virtual DOM with client-side rendering. Next.js supports React Server components, while client components are used for browser-specific functionality. Suspense and streaming are used for asynchronous rendering. Next.js Caching can be controlled using specific APIs. Server actions can be used for executing code on the server and submitting form data. The use of ActionState allows for form validation and error handling. The workshop concludes with discussions on error handling, code organization, and limitations of server actions.

Definiremos los términos y marcos básicos y entenderemos cómo se diferencian del uso tradicional de LLMs.Entenderemos las técnicas de prompting para agentes LLM y específicamente la técnica de React prompting para agentes de IA (no confundir con React el lenguaje de programación). Construiremos, desde cero, nuestro propio agente GenAI que puede interactuar con el usuario, realizar búsquedas en la web y codificar y ejecutar en Javascript.Tabla de contenidos:- Introducción a los agentes GenAI- Entendiendo el marco de React- Construcción práctica de un agente GenAI simple- Despliegue del Agente con streamlit- Consejos y marcos para desarrollar agentes GenAI

Building Your Own GenAI Agent Application

Welcome to the Workshop on Gen AI and LLM Agents! The Gen AI market is growing rapidly, with big companies investing in agent development using no-code tools. Chaining is a key concept in building trustworthy and complex systems in the Gen AI market. OpenAI 01 is the first model to integrate chain of thought thinking. LLM agents use step-by-step reasoning to provide answers and require a different framework than chain of thought. The React framework is successful for working with LLM agents. The process of React prompting involves iterating over tools to find the final answer. The Google search API is used as a tool in the LLM agent. The agent class is implemented to collect responses and decide the next action. The prompt is tweaked to include previous history. The LLM agent uses multiple tools, including the Google search API and a JavaScript code runner. The agent can perform calculations and retrieve data from web searches. Recommended resources for building advanced multi-agent systems include Langchain and Microsoft Autogen framework.

GenAI agents are one of the most promising directions for complex GenAI based applications. These agents can search the web, code, and carry complex tasks completely autonomously for the user. In this workshop we will learn the basics of GenAI agents. Define the basic terms and frameworks and understand how they differ from traditional use of LLMs.We will understand prompting techniques for LLM agents and specifically the React prompting technique for AI agents (not to be confused with React the programming language). We will build, from scratch, our own GenAI agent that can interact with the user, perform web searches and code and execute in Javascript.Table of contents:- Introduction to GenAI agents- Understanding the React framework- Hands-on Building of simple GenAI agent- Deployment of the Agent with streamlit- Tips, and frameworks for developing GenAI agents

La red que se encuentra entre nuestro servidor y el cliente es lo que causa la mayor complejidad en nuestro proceso de desarrollo. Ya sea la interfaz de usuario inicial que generamos en el servidor, las llamadas API que hacemos mientras el usuario navega, o los envíos de formularios que realiza nuestro usuario, mantener la aplicación receptiva y actualizada es una tarea enorme. ¿Cómo sería si toda esa complejidad simplemente desapareciera? Sería increíble, eso es lo que sería. Y React Server Components y Actions son lo que está haciendo eso posible. En esta charla, exploraremos cómo está sucediendo eso y cómo podemos aprovechar esta increíble experiencia de desarrollador para ofrecer experiencias de usuario aún mejores.

Abracadabra: La Red Desaparecida

I am so excited to share my software development experience. The talk focuses on React and the Vanishing Network, aiming to make network management disappear. It starts with the multi-page app paradigm and moves towards enhancing user experience and transitioning to single-page app architecture. The talk discusses eliminating duplication, transitioning to a JSON API, and utilizing React and user actions. It explores progressive enhancement with Remix, moving to modern React with server components, and enhancing server-client communication and UI. It also covers server-client code separation, Epic React version two, AI plugins, Next.js, trade-offs, testing, SQL queries, and optimizing for change.

The network that stands between our server and the client is what causes the most complexity in our development process. Whether it be the initial UI we generate on the server, the API calls we make as the user navigates around, or the form submissions our user makes, keeping the application responsive and up-to-date is a massive chore. What would it be like if all of that complexity just disappeared? Freaking great, that's what it would be like. And React Server Components and Actions are what's making that possible. In this talk we'll look into how that's happening and how we can take advantage of this amazing developer experience to deliver even better user experiences.

Abracadabra: The Vanishing Network

Gradualmente, pasaremos a utilizar las últimas características de React 19, incluyendo formularios del lado del servidor y los hooks más recientes para gestionar estados y errores de formularios. Al final de la masterclass, los participantes entenderán cómo crear formularios robustos con validación adecuada y manejo de errores.Objetivos de Aprendizaje<ul><li>Últimos Hooks de React 19 — useTransition, useFormStatus, useOptimistic, useActionState, useDeferredValue</li><li>Acciones del Servidor</li><li>Revalidaciones</li><li>Validación del lado del Servidor</li><li>Manejo de Errores</li><li>Prácticas de Seguridad</li></ul>

Evolución de la Gestión de Formularios en React

Welcome to the evolution of form management in React. Learn how to build forms using the latest React hooks. Handle forms with server actions, use validation, form status, optimistic, and action state. In this course, we'll turn the basic form into three different forms, including a server form that works without client-side JavaScript. Use the useFormStatus hook to provide real-time feedback about form submission status. The useActionState hook helps manage the state of a server action in React server components. The useOptimistic hook enables the creation of optimistic UIs. The useTransition hook distinguishes between urgent and non-urgent state updates. The useDeferredValue hook defers updating a part of the UI to keep it responsive during expensive updates. Practice and experiment to learn these concepts.

Learn how to handle forms in React using the latest features, such as startTransition, useTransition, useOptimistic, and useActionState, with and without React 19 server actions, alongside proper validation, error handling, and best practices.The workshop will begin by demonstrating traditional form handling using useState and useEffect for client-side rendering. Gradually, we'll transition to using the latest React 19 features, including server-side forms and the newest hooks for managing form states and errors.

Today's Talk focused on using refs and profiling Agigrid in React. The speaker shared their experience with optimizing custom cell components and performance, including using memo and leveraging the React compiler. They also discussed improving performance with manual style updates and refactoring the use of useEffect. The speaker highlighted the use of ref callbacks, which can be implemented with useLayoutEffect. React 19 introduces changes to the ref callback approach. The Talk touched on using React DevTools and CSS variables for monitoring renders. It also discussed the compatibility of Azure Grid with React and the trade-offs between using React components and vanilla JavaScript. The speaker emphasized the importance of considering the DX improvements and the complexity of not seeing a React component tree in the dev tools. The Talk concluded with a mention of AG Grid features, handling refs at various levels, and the recommendation to consult with Stephen for technical questions and application architecture.

While Refs are considered an escape hatch there are times when you might just need to use them.In this talk, with the help of real world examples, we will look at what Refs can do for us in terms of code clarity and also performance gains. Think along the lines of minimising renders and avoiding flickering UIs. We will cover the restrictions for safe usage and for those of you already using these patterns make sure you are prepared for the changes coming in React 19.

Construyendo aplicaciones multiinquilino escalables con Next.js

Hello and namaste, New York. I'm excited to talk about building scalable multi-tenant applications with Next.js. We'll cover what multi-tenancy is, its advantages, key considerations, and how Next.js aids in development. Before starting multi-tenancy, let's understand what a tenant is. In multi-tenant architecture, all tenants share the same app but have different access, roles, and permissions. Easy maintenance, efficiency, scalability, and cost-effectiveness are some of the benefits of multi-tenancy. However, challenges include scalability, isolation, security, and customization. Next.js allows for easy organization of different domains and paths. Dynamic routing in Next.js enables the customization of layouts for each tenant, ensuring a personalized look and feel. Next.js API routing allows for isolating data fetching for different tenants. Middleware can handle request validation and provide features like authentication, authorization, server-side redirects, conditional redirects, and data isolation. Next.js offers scalability through caching, a component-based and modular approach, load balancing, serverless functions and platforms, and different types of rendering. Next.js continues to evolve and is a popular choice for multi-tenant architecture.

In today’s digital landscape, multi-tenancy has become a critical architecture for SaaS platforms, marketplaces, and enterprise solutions. Next.js has continuously evolved, making it an increasingly popular choice for building full-stack applications. With each iteration, it has become even easier to develop scalable multi-tenant applications. Let’s talk about why multi-tenancy is vital, and how Next.js features such as dynamic routing, enhanced middleware, and edge functions simplify the process of building and scaling multi-tenant applications. We will talk about best practices, discuss real-world scenarios, and see a few examples in action.

Cualquiera puede publicar una biblioteca en NPM. Pero, ¿qué sucede cuando esa biblioteca es utilizada por millones de desarrolladores? ¿Cómo se manejan las complejidades de publicar uno de los paquetes más utilizados en el ecosistema y también lidiar con el soporte y mantenimiento de una comunidad? Veremos la mentalidad y el enfoque para enfrentar estos desafíos y lo que significa ser un "mantenedor" hoy en día, incluyendo prácticas para proporcionar soporte a los usuarios en todas las plataformas, mantener una mentalidad de "devrel", diseñar documentación, diseñar características y APIs, cómo considerar la versionado de paquetes y la compatibilidad, cuándo lanzar cambios disruptivos, desafíos técnicos con la publicación de paquetes y mantenerse al día con el ecosistema en constante evolución.

Mantener una Biblioteca y una Comunidad

Today's talk is about what it's like to be an open-source library maintainer, with examples and suggestions from the speaker's experience. Maintainers have various roles and responsibilities, including providing support for users and managing documentation. Setting boundaries, prioritizing documentation, and designing APIs are important aspects of being a maintainer. Release management and compatibility are challenging, requiring careful consideration of patch releases and breaking changes. The speaker shares an example of marking a method as deprecated in Redux and providing a migration path for users. Compensation for maintainers is a debated topic, and code mods can help with code migration. Maintainers often face challenges but can have a significant impact on the ecosystem and people's careers. Supporting open source developers is greatly appreciated.

Anyone can publish a library to NPM. But what happens when that library is used by millions of developers? How do you juggle the complexities of publishing one of the most widely used packages in the ecosystem, and also deal with supporting and maintaining a community? We'll look at the mindset and and approach to dealing with these challenges and what it means to be a "maintainer" today, including practices for providing user support across platforms, keeping a "devrel" mindset, designing documentation, designing features and APIs, how to consider package versioning and compatibility, when to ship breaking changes, technical challenges with publishing packages, and keeping up with the ever-evolving ecosystem.

Maintaining a Library and a Community

Desde bridgeful, a bridgeless, hasta Expo Modules y Static Hermes, el panorama de los módulos nativos en React Native está en constante evolución. La polinización cruzada, sin embargo, siempre ha sido limitada: es raro que React Native use módulos nativos de otros ecosistemas, y viceversa. En esta charla, presentamos Node-API, un estándar popular para exponer APIs nativas a JavaScript de manera ABI-estable, sin importar el motor. Usado en Node.js y la mayoría de los otros entornos de ejecución de JavaScript importantes, es la tecnología ideal para compartir módulos nativos entre ecosistemas. ¡Mostraremos cómo ya está siendo utilizado por Microsoft en React Native Windows, y lo que puede significar para el futuro de React Native!

React Native, Meet node.js Native Addons

We'll be going over the use cases of Node.js native add-ons and how they are written with NodeAPI. ABI stability allows swapping out older versions of a library for newer ones without recompiling the rest of the app. Node API enables the use of the latest Hermes regardless of React Native Windows. NativeScript is a library for calling native APIs from JavaScript, eliminating the need for dealing with native code. To initialize the addon in React Native, we modified the approach by auto-linking the native script XC framework. We can read the battery level using inline JavaScript and make view changes like setting the background color. React Native reanimated can be used to work on the UI thread. Support for Node.js native add-ons and completion of the official ABI stable Hermes API would open up the ecosystem.

From bridgeful, to bridgeless, to Expo Modules and Static Hermes, the landscape of native modules in React Native is ever-evolving. Cross-pollination, however, has always been limited – it is rare for React Native to use native modules from other ecosystems, and vice versa. In this talk, we introduce Node-API, a popular standard for exposing native APIs to JavaScript in an ABI-stable manner, no matter the engine. Used in Node.js and most other major JavaScript runtimes, it is the ideal technology for sharing native modules cross- ecosystem. We'll show how it's being used by Microsoft in React Native Windows already, and what it may mean for the future of React Native!

Los flujos de trabajo de diseño a veces pueden estar en desacuerdo con el desarrollo, pero establecer patrones comunes entre disciplinas puede sentar las bases para la automatización y permitir que los equipos diseñen y lancen más rápido. Figma te permite obtener lo que necesitas del diseño y volver a escribir código, ya sea construyendo front-end por primera vez o construyendo con un sistema de diseño reutilizable en tu base de código.

Alineación de Patrones entre Diseño y Desarrollo

I'm Jake, a developer advocate at Figma, and today I'll be discussing aligning patterns between design and development. Collaboration between designers and developers requires recognizing our different perspectives. The goal is to close the gap between design and development, but this is often aspirational. The optimal path between design and development is somewhere in between, depending on factors like friction or waves. By recognizing each other's areas of resistance, we can find ways to make collaboration more effective. Figma's Code Connect fills the gap between Figma component logic and code logic by allowing teams to publish code-based informed component code snippets. CodeConnect currently supports HTML, Web Components, Angular, Vue, React, SwiftUI, and Jetpack Compose, and seeks to support more languages.

Design workflows can sometimes be at odds with development—but establishing common patterns between disciplines can set the foundation for automation and enable teams to design and ship faster. Figma allows you to get what you need from design and get back to writing code—whether that’s building front-end for the first time, or building with a reusable design system in your code base.

Explora los Componentes del Servidor a través de la lente de Componentes de IU reutilizables, donde todo "depende" de los requisitos individuales del caso de uso y las necesidades individuales de la aplicación. En lugar de luchar entre 'servidor' y 'cliente', tengamos lo mejor de ambos mundos.

Componentes React Polimórficos para el Cliente y el Servidor

Hi, my name is Kirill and I have a little obsession with UI components. Let's talk React, specifically React 19 Server Components. I will show you how to build a polymorphic data table using server components. We explore mixing server and client components and applying the composition pattern. We discuss polymorphic components and separating client logic to render custom components without breaking client functionality. The component can be used in different environments, morphing into server or client components accordingly. This talk focuses on building a polymorphic component with minimal bundle size and access to both server and client APIs.

Explore Server Components through the lens of reusable UI Component, where everything "depends" on the individual requirements of the use-case and individual application needs. Instead of fighting over 'server' vs 'client' - let's have the best of both worlds.
