La distinción entre el estado del servidor y el estado del cliente en nuestras aplicaciones puede ser un concepto nuevo para algunos, pero es muy importante entenderlo cuando se entrega una experiencia de usuario de primera calidad. El estado del servidor viene con problemas únicos que a menudo se cuelan en nuestras aplicaciones sorpresa como: - Compartir datos entre aplicaciones- Caché y Persistencia- Deduplicación de Solicitudes- Actualizaciones en segundo plano- Gestión de Datos "Obsoletos"- Paginación y Recuperación Incremental- Memoria y Recolección de Basura- Actualizaciones Optimistas Los gestores tradicionales de "Estado Global" pretenden que estos desafíos no existen y esto finalmente resulta en que los desarrolladores construyan sus propios intentos sobre la marcha para mitigarlos. En esta masterclass, construiremos una aplicación que expone estos problemas, nos permite entenderlos mejor, y finalmente los convierte de desafíos a características usando una biblioteca diseñada para gestionar el estado del servidor llamada React Query. Al final de la masterclass, tendrás una mejor comprensión del estado del servidor, el estado del cliente, la sincronización de datos asíncronos (un bocado, lo sé), y React Query. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Repensando el Estado del Servidor con React Query

Welcome to my workshop on React Query, a powerful library for fetching data in React applications. We explore custom hooks and fetching data, as well as using React Query for data fetching and caching. We also learn about handling mutations, optimistic updates, and query prefetching. React Query simplifies global state management and provides a seamless user experience with instant data access and background fetching. The workshop concludes with a discussion on comparing React Query to SWR and the importance of sharing positive experiences with the library.

The distinction between server state and client state in our applications might be a new concept for some, but it is very important to understand when delivering a top-notch user experience. Server state comes with unique problems that often sneak into our applications surprise like: - Sharing Data across apps- Caching &amp; Persistence- Deduping Requests- Background Updates- Managing “Stale” Data- Pagination &amp; Incremental fetching- Memory &amp; Garbage Collection- Optimistic Updates Traditional “Global State” managers pretend these challenges don’t exist and this ultimately results in developers building their own on-the-fly attempts to mitigate them. In this workshop, we will build an application that exposes these issues, allows us to understand them better, and finally turn them from challenges into features using a library designed for managing server-state called React Query. By the end of the workshop, you will have a better understanding of server state, client state, syncing asynchronous data (mouthful, I know), and React Query. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Rethinking Server State with React Query

React sigue evolucionando y haciendo que las cosas difíciles sean más fáciles para el desarrollador promedio. Un caso en el que React no era particularmente difícil pero muy repetitivo, es trabajar con solicitudes AJAX. Siempre hay una trinidad de estados de carga, éxito y posibles errores que deben manejarse cada vez. Pero ya no, ya que el componente `&lt;Suspense /&gt;` facilita mucho la vida. Otro caso es el rendimiento de aplicaciones más grandes y complejas. Por lo general, React es lo suficientemente rápido, pero con una aplicación grande, la renderización de componentes puede entrar en conflicto con las interacciones del usuario. El renderizado concurrente se encargará de esto, en su mayoría de forma automática. Aprenderás todo sobre cómo usar &lt;Suspense /&gt;, mostrar indicadores de carga y manejar errores. Verás lo fácil que es comenzar con el renderizado concurrente. Harás que el suspense sea aún más capaz combinándolo con el renderizado concurrente, el gancho `useTransition()` y el componente &lt;SuspenseList /&gt;. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Comenzando con Suspense y Renderizado Concurrente en React

This workshop explores suspense, lazy loading, bundle splitting, and data resources in React. It covers UI approaches to make applications appear faster and concurrent modes for more responsive applications. React.lazy is used to optimize loading and bundle size, while React Suspense is used to suspend rendering until components are loaded. Data resources can be created using the same principle as React.lazy. The workshop also discusses error handling, parallel suspense, and fetching data before rendering. Concurrent modes offer a solution to rendering delays and event handling in single-threaded JavaScript environments.

React keeps on evolving and making hard things easier for the average developer. One case, where React was not particularly hard but very repetitive, is working with AJAX request. There is always the trinity of loading, success and possible error states that had to be handled each time. But no more as the `&lt;Suspense /&gt;` component makes life much easier. Another case is performance of larger and complex applications. Usually React is fast enough but with a large application rendering components can conflict with user interactions. Concurrent rendering will, mostly automatically, take care of this. You will learn all about using &lt;Suspense /&gt;, showing loading indicators and handling errors. You will see how easy it is to get started with concurrent rendering. You will make suspense even more capable combining it with concurrent rendering, the `useTransition()` hook and the &lt;SuspenseList /&gt; component. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Nx es una suite de herramientas de construcción de próxima generación. Next.js es un framework de última generación para construir aplicaciones web. Juntos, brindan orden al caos de construir múltiples aplicaciones web en varios equipos. Esta charla es un resumen rápido de cómo Nx puede ayudarte a mantener múltiples aplicaciones Next.js, con múltiples equipos, al mismo tiempo que compartes componentes y bibliotecas para una experiencia de usuario consistente. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Nx + Next.js = ❤

Hey everybody, my name is Adam Ellibert, aka Big AB, and I am a core contributor on a project called NX. Today, I'm going to go through a whirlwind tour of a really cool way to do web development using NX. NX is a suite of dev tools to improve developer experience, and it's extensible, plugin-based, and open-source. I'll show you some of the commands that NX provides, such as creating an NX workspace, generating schematics, serving as a dev server, building applications, and running tests. NX also has a variety of plugins, including the Next.js plugin. And if you're not comfortable with command-line interfaces, there's a GUI available for you. I'm going to create an NX workspace and choose Next.js as my first application. Then I'll create another app called Uber for Star and add a dashboard page. I'll also create a shared components library and configure storybook for it. Finally, I'll use NxServe to serve my Uber 4 app. This setup includes a splash page, a dashboard page, and a design system using storybook. We've got shared components for our marketing website and Uber 4 app. We also have end-to-end directories for Cypress tests and jest for unit tests. Our Uber 4 app is similar to any other Next.js app with pages and a nested dashboard page. We import shared components by prefixing them with the org name and library name. NX handles dependencies, ensuring everyone is on the same version and allows scoping imports to the org. Computation caching optimizes test and build runs by caching results that are unaffected by code changes. NX brings easy application creation with consistent commands and shared library extraction. Generators save time and enforce best practices. NX provides modern tools like Cypress, Storybook, Prettier, ESLint, and Next.js. The Next.js plugin creates and configures Next.js applications, serving them in dev mode and building production-ready and static apps. Visit nx.dev for more information.

Nx is a next generation suite of build tools. Next.js is state-of-the-art framework for building web applications. Together they bring order to the chaos of building multiple web applications across many teams. This talk is a quick rundown of how Nx can help you maintain multiple Next.js apps, with multiple teams, while sharing components and libraries for consistent user experience. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Cada bug es diferente: Algunos acechan durante meses, otros aparecen repentinamente después de la actualización de una dependencia. Algunos son introducidos por nosotros, otros por otros equipos o sistemas. Algunos son dolorosamente obvios y afectan a todos los usuarios, otros solo ocurren en casos extremos. Y las formas de encontrarlos y, eventualmente, prevenirlos, son igual de diversas: ya sea a través de pruebas de captura de pantalla, unitarias, de integración, de extremo a extremo o pruebas visuales automatizadas, cada tipo tiene sus desafíos y oportunidades. Probar interfaces de usuario es difícil, pero al final, solo la automatización de pruebas puede brindarnos la confianza que necesitamos para avanzar rápidamente y refactorizar nuestro código implacablemente. En esta charla vamos a ver qué tipos de bugs existen, qué pruebas son más efectivas para atraparlos y cómo podemos implementarlas utilizando tecnologías modernas en el front-end.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Bugs Fantásticos y Dónde Encontrarlos

TypeScript is a JavaScript-based language used for mobile apps. Testing rules include ensuring tests fail when something goes wrong and only fail when necessary. Integration testing can be done using tools like Cypress and Netflix PolyJS. Visual regression testing compares screenshots of changes and helps prevent visual bugs. Starting with end-to-end tests and writing tests for bugs encountered are recommended for beginners.

Every bug is different: Some are lurking around for months, others appear suddenly after the upgrade of a dependency. Some are introduced us, others other teams or systems. Some are painfully obvious and affect all users, others only occur in edge (cases). And the ways of finding, and eventually, preventing them, are just as diverse: be it snapshot, unit, integration, end to end tests or automated visual tests, every kind comes with its challenges and opportunities. Testing UIs is hard, but in the end, only test automation can give us the confidence we need to move fast and refactor our code relentlessly. In this talk we are going to look at what kinds of bugs there are, which tests are most effective for catching which, and how we can implement them using modern front end technologies. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Muy a menudo, A11Y es solo una idea secundaria y se agregará a un proyecto "cuando tengamos tiempo", es decir, nunca. Pero hay muchas razones por las que deberías desarrollar teniendo en cuenta la accesibilidad desde el principio, incluyendo algunas que convencerán a los superiores. Exploraremos las herramientas que podemos usar para ayudarnos a desarrollar de manera más accesible y hablaremos sobre algunas de las peculiaridades y limitaciones que tiene React Native. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Accesibilidad como un Ciudadano de Primera Clase

TypeScript and React are popular languages for software development. Accessibility is important for inclusivity and preventing lawsuits. Building accessibility from the start is crucial, considering design and engineering aspects. Tooling for React Native accessibility is limited. Setting the accessible prop and role in components is essential for screen reader users. The React Native documentation is helpful, but some accessibility needs may require additional attention.

All too often A11Y is only an afterthought and will be added to a project "when we have time" i.e. never. But there are a many reasons why you should develop with a11y in mind from the start including some that will convince The Higher-Ups. We'll explore tools we can use to help us develop more accessibly and talk about some of the quirks and limitations that React Native has. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Accesibilidad en React: Más allá de lo básico

Today's Talk on React Accessibility covers the importance of manual testing, the challenges faced in addressing accessibility, the impact of accessibility on user experience, and the use of subtitles and user settings for accessibility. It emphasizes the need for manual testing in addition to automated testing, the role of empathy training in understanding accessibility challenges, and the significance of addressing accessibility issues for all users. The Talk also highlights the benefits of implementing accessibility features, such as increasing website accessibility for disabled markets and improving user experience for all.

Accessibility in React has been a hot topic in the last few years, but in this talk, we'll be going beyond the basics. We'll discuss what disability means beyond what you've heard before, and then use code examples to learn why semantic HTML is helpful, and when it's just not enough. We'll then look into tooling, and talk about how you can introduce accessibility testing into your teams and existing code. You'll leave with the tools and knowledge to make a difference starting today. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

React Accessibility: Beyond the Basics

Jen Luker

¡Así que has construido una biblioteca de componentes! ¡Felicidades! Estoy seguro de que es increíble, pero ¿has puesto el mismo esfuerzo en su documentación? Las bibliotecas de componentes tienden a tener APIs gigantes, docenas de componentes, cientos de props y miles de combinaciones. Eso es mucha información para desempacar. Podríamos hacer la documentación muy extensa o... súper interactiva. Combinamos vistas previas de componentes, documentación de API, edición de props y edición de código en una experiencia única y fluida. Puedes explorar rápidamente varias configuraciones de cada componente mientras ves cómo se escribe el código. Esta charla te mostrará cómo aprovechar herramientas y conceptos comunes como Prettier, babel y transformaciones AST para construir una documentación que literalmente puede trabajar para ti. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Presentando React View

ReactJS is a JavaScript-based framework that emphasizes the importance of building amazing documentation to reduce questions. The speaker discusses the custom website built using Next.js and MDX, and the challenges of dealing with JSX and the compilation process. The talk also covers interacting with NAPs, extracting information from code using AST, and the benefits of using Babel and AST Explorer. The process of building and generating code with AST is explained, along with the importance of documentation and ReactVue. The speaker also provides insights on getting started with documentation, building custom documentation, and keeping it in sync with the code.

So you built a component library. Congrats! I am sure it is awesome but did you put the same effort into its documentation? Component libraries tend to have giant APIs, dozens of components, hundreds of props and thousands of permutations. That is a lot of information to unpack. We could make the documentation very long or... super interactive. We combined component previews, API documentation, props editing and code editing into a single seamless experience. You can quickly explore various settings of each component while watching the code write itself. This talk will show you how to leverage common tools and concepts such as Prettier, babel and AST transformations to build the documentation that can literally work for you. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

El hilo principal, en la web, tiene muchas responsabilidades. Al mismo tiempo, las aplicaciones web se están volviendo más sofisticadas cada día. Por lo tanto, el hilo principal se vuelve demasiado ocupado y decepcionará a nuestros usuarios mostrando cuadros entrecortados. La arquitectura fuera del hilo principal garantiza que las aplicaciones se ejecuten sin problemas en todos los dispositivos para todos. En esta charla, exploraremos las posibilidades en los navegadores, como WebWorker, Worklet y WebAssembly, presentando herramientas prácticas que nos permiten mejorar nuestras experiencias de usuario.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¡Deja respirar al hilo principal!

Let's explore how to improve web application performance by offloading tasks from the main thread to other threads. We need to ensure compatibility with all devices and users to avoid frustrating experiences. Web Workers and Web Assembly can help improve performance by offloading tasks, but there are trade-offs to consider. Converting existing codebases to WebAssembly can be done gradually, and it's important to measure performance before making the conversion.

The main thread, on the web, has a lot of responsibilities. At the same time, web apps are getting more sophisticated every day. Therefore, the main thread gets too busy that will disappoint our user showing janky frames! The off-main-thread architecture ensures apps run smoothly on every device for everyone. In this talk, we will go through the possibilities in browsers such as WebWorker, Worklet, and WebAssembly introducing practical tools that allow us to boost our user experiences. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Markdown es genial para sitios impulsados por contenido. MDX es aún mejor, ya que te permite incrustar componentes interactivos directamente desde tu marcado. Por lo general, se utiliza para los mismos diseños lineales que a menudo se ven en muchos blogs, readmes y sitios de documentación. Pero no tiene que ser así. En esta charla, veremos cómo remodelar MDX para poder utilizarlo en diseños muy diferentes, como scrollytelling, presentaciones de diapositivas y más. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

La X en MDX

Markdown is extended by MDX to support more content and layouts. MDX allows for customization of rendering and extraction of data. It is often used for embedding interactive components. MDX can be used to create custom layouts and synchronize steps with media. Codehike is a project focused on code wall tools and explaining code.

Markdown is great for content-driven sites. MDX is even better, letting you embed interactive components directly from your markup. It's usually used for the same linear layouts you often see on many blogs, readmes, and documentation sites. But it doesn't need to be like this. In this talk, we'll see how to reshape MDX so we can use it for very different layouts, things like scrollytelling, slide decks, and more. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

La genialidad de JS va más allá de las páginas web. Primero escribiremos un juego en 2D (en Javascript) - y luego - escribiremos código de IA (¡en Javascript!) que será capaz de ganar este juego por nosotros. ¡Oh, qué época para estar vivo! <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Los juegos son más inteligentes que nosotros

Today's Talk explores game development using JavaScript, including building games in the browser, using game engines, and utilizing the BitMellow framework. It also delves into the concept of using AI to make computers play games, discussing reinforcement learning and implementing it in games like Flappy Bird. The Talk highlights the process of teaching the agent to learn, modifying rewards to improve performance, and the journey of game development from initial stages to advanced AI integration.

JS awsomeness beyond webpages. First we'll write a cool 2D game (in Javascript) - and then - write AI code (in Javascript!) that will be able to win this game for us. Oh, what a time to be alive! <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

En esta charla voy a convencerte de que los componentes de UI pagados resolverán todos tus problemas, y que deberías darme todo tu dinero de inmediato. Tal vez. O quizás me basaré en mi experiencia trabajando tanto en herramientas gratuitas y de código abierto (jQuery, jQuery UI, NativeScript), como en herramientas pagadas (Kendo UI, KendoReact), y discutiré qué tipo de herramienta tiene sentido según tu equipo y necesidades. En cualquier caso, la charla será rápida porque el rayo está en el título.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Por qué los componentes de UI pagados no son malos

Paid UI components are not evil and offer benefits such as guaranteed support and long-term peace of mind. They solve harder problems and provide features and guarantees that free controls may not have. Paid components also establish a direct financial relationship with the authors, eliminating the need for sponsorship or donation models.

In this talk I’m going to convince you that paid UI components will solve all your problems, and that you should immediately give me all of your money. Maybe. Or perhaps I’ll draw on my experience working both on free and open source tools (jQuery, jQuery UI, NativeScript), as well as paid tools (Kendo UI, KendoReact), and discuss which type of tool makes sense depending on your team and needs. In any case the talk will go fast because lightning is in the title. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Panel Discussion: Testing

Tomasz Łakomy

Google anunció que cambiará por completo a rastrear e indexar sitios utilizando la indexación móvil primero en marzo de 2021. Ahora, para algunas empresas, su sitio móvil se renderiza dinámicamente, lo que tiene un alto riesgo de disminuir su clasificación en Google una vez que se implemente por completo la indexación móvil primero. Esta presentación compartirá cómo evaluar qué cambios deben realizarse, las mejores prácticas para aumentar el SEO para la indexación móvil primero, cómo aumentar el rendimiento y cómo convertir partes de tu sitio de renderizado dinámico a responsive en menos de dos meses. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Mejora tu SEO

We're introducing our new release and livestream, explaining mobile-first indexing and its impact on SEO. Teachers Pay Teachers faced challenges with Google's move to mobile-first indexing, prompting them to optimize their mobile pages. They combined teams, tested performance, increased page speed, fixed structured data issues, and showed hidden content to improve search ranking. To optimize mobile pages for Googlebot, it is important to update mobile content, increase page speed, and test performance and SEO.

Google announced that they will fully switch over to crawling and indexing sites using mobile-first indexing March 2021. Now for some companies their mobile site is dynamically rendered which has a high risk of decreased ranking on google once mobile-first indexing is fully implemented. This presentation will share how to assess what changes needs to be made, best practices to increase SEO for Mobile First Indexing, how to increase performance, and how to turn parts of your site from dynamic rendering to mobile responsive in less than two months. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¿Sabías que la primera novela escrita data del año 1021? Su autora es la noble japonesa Murasaki Shikibu. Desde entonces, innumerables escritores han plasmado sus pensamientos en papel y numerosos lectores han experimentado sus historias. Las personas escriben durante décadas y nosotros, como desarrolladores de software, de alguna manera ignoramos su oficio. Nosotros también escribimos, no novelas, pero software. ¿No es acaso esto también escribir? Creas ficción o código, hay mucho en común. En esta presentación veremos qué tan cerca estamos de gigantes como Hemingway y Stephen King. ¿Podemos obtener algo de su sabiduría y aplicarla a nuestro trabajo diario como ingenieros? Ven a esta charla y obtendrás algunos consejos prácticos. Espero que mi presentación te convierta en un desarrollador React un poco mejor.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Todos somos Hemingway

This Talk covers important tips for software development, focusing on React. Starting with what you know and building on it is emphasized. Asking the right questions and simplifying components demonstrates seniority. Reading code and asking questions are crucial for finding better solutions. The connect function in React Red Hook's library and the function-as-child component pattern are highlighted. Writing code that is easy for others to understand and maintain is emphasized. The importance of retrying on the server and refactoring for the ecosystem is mentioned.

Do you know that the first novel ever written dates back in 1021. Its author is the Japan noblewoman Murasaki Shikibu. Till then countless of writers put their thoughts on paper and countless of readers experience their stories. People write for decades and we, as software developers, kind of ignore their craft. We write too. Not novels but software. Isn't it this still writing? Believe it or not there is a lot in common between creating fiction and writing code. In this presentation we will see how close we are to giants like Hemingway and Stephen King. Can we get some of their wisdom and apply it to our daily job as engineers. Come to this talk and will get a few practical advices. I hope my presentation will make you a slightly better React developer. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
