La adición de la API de hooks a React fue un cambio bastante importante. Antes de los hooks, la mayoría de los componentos tenían que ser basados en clases. Ahora, con los hooks, estos son a menudo componentes funcionales mucho más simples. Los hooks pueden ser realmente simples de usar. Casi engañosamente simples. Porque todavía hay muchas formas en las que puedes equivocarte con los hooks. Y a menudo resulta que hay muchas formas en las que puedes mejorar tus componentes con una mejor comprensión de cómo se puede usar cada hook de React.Aprenderás todo sobre los pros y los contras de los diversos hooks. Aprenderás cuándo usar useState() versus useReducer(). Veremos cómo usar useContext() de manera eficiente. Verás cuándo usar useLayoutEffect() y cuándo useEffect() es mejor. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Consejos sobre React Hooks que solo los profesionales conocen

This workshop on React Hooks Tips explores hooks beyond the basics, covering common mistakes, advanced hooks, creating custom hooks, and the rules of hooks. It demonstrates the use of useState, useEffect, and useContext hooks, as well as creating custom hooks for managing state and performing side effects. The workshop also covers the use of useRef, useReducer, and useLayoutEffect hooks, and provides insights into how React hooks work under the hood. It concludes with the implementation of a provider component and the use of context and reducers to manage complex state in functional components.

The addition of the hooks API to React was quite a major change. Before hooks most components had to be class based. Now, with hooks, these are often much simpler functional components. Hooks can be really simple to use. Almost deceptively simple. Because there are still plenty of ways you can mess up with hooks. And it often turns out there are many ways where you can improve your components a better understanding of how each React hook can be used.You will learn all about the pros and cons of the various hooks. You will learn when to use useState() versus useReducer(). We will look at using useContext() efficiently. You will see when to use useLayoutEffect() and when useEffect() is better. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Mucho ha cambiado en el mundo de la gestión del estado en React en los últimos años. Donde Redux solía ser la principal biblioteca para esto, la introducción de las API de Contexto y Hooks de React ha revolucionado las cosas. Ya no necesitas bibliotecas externas para manejar tanto el estado del componente como el estado global en tus aplicaciones. En este masterclass aprenderás los diferentes enfoques para la gestión del estado en la era post-Redux de React, ¡todos basados en Hooks! Y como bonificación, exploraremos dos próximas bibliotecas de gestión del estado en el ecosistema de React.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Gestión del estado en React con Context y Hooks

Today's workshop focuses on state management in React using the Context API and Hooks. The Context API is now a viable option for state management and provides additional features for effective state management. Custom hooks can be created to handle local state and access values from the context. Combining multiple contexts and using the useMemo hook can prevent unnecessary component rerenders. The useReducer hook allows for more complex state logic, similar to Redux. Debugging can be done by creating custom hooks and logging actions. Context can be used for global state management by separating providers into different components. The workshop includes exercises to practice using context and breakout rooms for discussion. The Q&A session covers fetching data and managing errors with context.

A lot has changed in the world of state management in React the last few years. Where Redux used to be the main library for this, the introduction of the React Context and Hook APIs has shaken things up. No longer do you need external libraries to handle both component and global state in your applications. In this workshop you'll learn the different approaches to state management in the post-Redux era of React, all based on Hooks! And as a bonus, we'll explore two upcoming state management libraries in the React ecosystem. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Como desarrolladores, lanzamos características a diario, pero ¿cómo aseguramos que esas características funcionen correctamente en producción antes de lanzarlas a todos los usuarios? Si me preguntas, la respuesta son los feature flags. Los feature flags son beneficiosos porque te permiten probar tu código en producción, realizar lanzamientos canarios e incluso realizar pruebas A/B. El poder de React facilita la implementación de estos flags. Te guiaremos en cómo crear fácilmente un feature flag en la interfaz de usuario, instalar dependencias con npm e implementar tu feature flag en tu aplicación de React. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Configuración de Feature Flags con React

This Talk discusses setting up feature flags with React, which allows for controlled rollouts of new features. Feature flags provide more control without touching the source code and can target specific users or types of users. In React, feature flags can be created and configured using Split.io. Different treatments can be applied to determine if a feature should be shown. Feature flagging provides control and flexibility in development.

As developers, we release features daily – but how do you ensure those features are working properly in production before you release them to all your users? If you ask me, the answer is feature flags! Feature flags are beneficial because they allow you to test your code in production, perform canary releases, and even conduct A/B testing. The power of React makes it easy to implement these flags. We will walk through how to easily create a feature flag in the UI, install dependencies with npm, and implement your feature flag in your react app. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Los usamos todo el tiempo, y creemos que sabemos cómo funcionan los state hooks (useState, useReducer). Pero bajo el capó, como era de esperar, las cosas no son como te imaginas. Esta charla trata sobre las colas de actualización, el agrupamiento, las actualizaciones ansiosas y perezosas, y algunas otras cosas interesantes aprendidas al mirar el código fuente de los Hooks. También contiene consejos prácticos que te ayudarán a comprender y depurar mejor tu código. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

No sabemos cómo funcionan los React State Hooks

This Talk provides an introduction to React Staytools, explaining how to use the state and setState function to update a counter. It also delves into the inner workings of React rendering, discussing the update queue and re-rendering conditions. The Talk concludes by mentioning the different modes of updating and triggering re-renders in React, and encourages further exploration of the source code and discussion in Discord.

We use them all the time, and we think we know state hooks work (useState, useReducer). But under the hood, as expected, things are not what you imagine. This talk is about update queues, batching, eager and lazy updates, and some other cool things learned from looking at Hooks source code. It also contains practical takeaways that will help you better understand and debug your code. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

We Don’t Know How React State Hooks Work

Con React 16.0, Facebook ha lanzado una actualización del algoritmo de reconciliación del núcleo de React que se llamó "Fiber". Fiber permite a React romper los límites de la pila de llamadas y pausar/iniciar el trabajo de renderizado a voluntad. En esta charla, exploraremos por qué era necesario Fiber, cubriremos algunos detalles de implementación internos de Fiber y veremos Fiber en acción con el Modo Concurrente experimental de React. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Dentro de Fiber: Una Visión General del Algoritmo de Reconciliación de React

React Fiber is a reconciliation algorithm introduced in React 16 to address laggy input fields and heavy rendering. The old stack reconciler caused a laggy experience by re-rendering the entire subtree immediately. React Fiber solves this by breaking work into incremental units and assigning priorities. It introduces concurrent mode to make apps responsive and adaptable. The useDeferredValue hook is commonly used to keep the interface responsive by rendering components immediately and others at a later time.

With React 16.0, Facebook has released an update to the React core reconciliation algorithm which was named ""Fiber"". Fiber allows React to break the limits of the call stack and pause/start rendering work at will. In this talk, we will explore why Fiber was necessary, cover some of the internal implementation details of Fiber, and see Fiber in action with React's experimental Concurrent Mode. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

En esta charla discutiremos cómo combinar el poder de D3 como una biblioteca matemática con las capacidades de renderizado de React. ¿Cómo podemos encapsular la animación para reutilizarla con componentes funcionales de React? ¿Cómo podemos lidiar con las restricciones en las estructuras de datos para crear visualizaciones interesantes? ¿Cómo abordar los problemas de rendimiento cuando hay múltiples elementos animados en la pantalla? Estas son algunas de las preguntas que se abordarán a medida que profundizamos en las técnicas aplicadas a ejemplos del mundo real.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Técnicas probadas en batalla para animación y visualización de datos con React

Motion is a powerful tool in data visualization, but it must be used carefully to avoid confusion. Implementing charts with React and D3 can improve the user experience. The use of D3 scales and react-spring can enhance animations. Canvas is a better choice for rendering many elements. Accessibility considerations should be made to accommodate users who prefer reduced motion.

In this talk we will discuss how to combine the power of D3 as a math library with React's rendering capabilities. How can we encapsulate animation for reuse with React functional components? How can we deal with restrictions in data structures to create interesting visualizations? How to approach performance issues when there are multiple animated elements on the screen? These are some of the questions that will be addressed as we dig deeper into techniques applied to real-world examples. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Los temas serán el diseño de componentes reutilizables de React, GraphQL, enrutamiento en la aplicación, ciclo de vida de la aplicación, controles de teclado, mensajes de aviso y otros.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Arquitectura de React Native en Product Hunt

The speaker discusses their React Native architecture and how they structured their app, choosing React Native over native development due to limited resources and the need for UI experimentation. The architecture consists of support, components, and screens, with a focus on code organization and extensibility. The speaker explains the screen creation process, including the use of React Native Navigation and a state machine pattern. They also highlight the use of GraphQL for data retrieval and navigation between screens. The talk covers the structure of common components, utilities for styling, and support for dark mode. Overall, the speaker emphasizes the importance of isolating dependencies and utilizing a directory structure approach.

I'm going to showcase the React Native architecture we use in our new mobile app at Product Hunt. What we learned, among the way. How we moved what we know from web to mobile. Topics will be designing reusable React components, GraphQL, routing in the app, application lifecycle, keyboard controls, toast messages, and others. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

En este masterclass, veremos algunos de los enfoques y técnicas que se pueden aplicar al hacer refactorizaciones o agregar nuevas características a una base de código heredada de React para alinearlo con los enfoques más recientes. Cubriremos temas como cómo usar React Hooks para compartir la lógica de los componentes de una manera que permita reutilizar en componentes de clase; cómo introducir de forma incremental otros patrones en una aplicación de React Redux; y cómo construir componentes de interfaz de usuario flexibles a través de abstracciones donde estemos vinculados a CSS global o una biblioteca de componentes. En el camino, tocaremos muchos patrones de React y enfoques de gestión de estado con el objetivo final de poder evaluar estas opciones y permitir que nuestros requisitos impulsen la arquitectura para avanzar hacia una base de código más sólida y mantenible. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Adoptar de forma incremental los patrones modernos de React en una base de código heredada

This workshop focuses on incrementally adopting modern React patterns in a legacy codebase. It covers topics such as building reusable component logic hooks, refactoring legacy code to use hooks, and using context with hooks. The importance of refactoring class components to functional components and using hooks whenever possible is emphasized. The workshop also explores the use of Redux for centralized state management and the use of context for global state. Troubleshooting and error handling are discussed, and the workshop provides exercises for hands-on practice.

In this workshop, we’ll look at some of the approaches and techniques that can be applied when making refactors or adding new features to a legacy React codebase to bring it inline with the latest approaches. We’ll cover topics such as how to use React Hooks to share component logic in a way that will allow reuse in class components; how to incrementally introduce other patterns to a React Redux app; and how to build in flexible UI components via abstractions where we are tied to some global CSS or a component library. Along the way, we’ll touch on many React patterns and state management approaches with the ultimate aim of being able to evaluate these options and let our requirements drive the architecture in moving towards a more robust and maintainable codebase. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

El CEO y cofundador de Netlify, Matt Biilmann, reflexiona sobre la historia de React, las promesas de Jamstack y la complejidad que puede surgir en los flujos de trabajo de los desarrolladores si no seguimos defendiendo la simplicidad con el tiempo. En esta charla relámpago, Matt describe los compromisos a los que se enfrentan los desarrolladores para entregar sitios grandes e introduce una nueva idea para una solución futura más escalable. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Manteniéndolo Simple

React brought simplicity to building browser-based applications, but as new concepts like context, hooks, server components, and streaming are introduced, it's important to know the current state of the application. The JAMstack simplifies reasoning about the state of web properties through immutable assets and atomic deploys. However, as the JAMstack evolves, challenges arise in areas such as build times and API caching for large projects, especially e-commerce.

Netlify CEO and co-founder Matt Biilmann reflects on the history of React, the promises of the Jamstack, and the complexity that can creep into developer workflows if we don't continue to defend simplicity over time. In this lightning talk, Matt describes the trade-offs developers face to deliver large sites and introduces a new idea for a more scalable future solution. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

En esta charla, veremos cómo construir un sistema de autenticación de usuarios en React utilizando Magic, donde Magic proporciona una solución de identidad basada en claves construida sobre el estándar de Identidad Descentralizada (DID), donde las identidades de los usuarios son soberanas y aprovechan pares de claves públicas y privadas de blockchain. Estos pares de claves se utilizan para generar pruebas de conocimiento cero para autenticar a los usuarios en lugar de tener que depender de que los usuarios proporcionen contraseñas a Magic o a cualquier proveedor de identidad.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Autenticación de usuarios de React para la identidad soberana con Magic

Welcome to this talk about React user authentication for self-sovereign identity with Magic Labs. Learn how the user trust model of the internet is broken and a novel solution to fix it. Understand the concept of zero-knowledge proof and the key-based model for user identity. Magic improves trust by leveraging Infrastructure-as-a-Service, secure user keys, and providing passwordless authentication. Explore decentralized identity and how it solves the authentication problem, including the use of decentralized identity tokens (DIDT) for managing permissions and authentication.

In this talk, we’ll see how to build a user authentication system in react using magic, where magic provides a key-based identity solution built on top of the Decentralized Identity (DID) standard, where users’ identities are self-sovereign leveraging blockchain public-private key pairs. These key pairs are used to generate zero-knowledge proofs to authenticate users instead of having to rely on users providing passwords to Magic or any identity provider. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
