NextJS 13.4 cambió el juego con el Enrutador de la Aplicación y los componentes del Servidor React. El cambio al modelo de gestión de estado parece simple al principio, pero se vuelve complejo muy rápidamente cuando intentas crear las experiencias prácticas diarias del usuario que eran sencillas en el modelo de páginas. Hablaremos sobre los diferentes modelos de gestión de estado, cómo funcionan en el Enrutador de la Aplicación y cómo decidir cuál deberías usar.

Video Summary and Transcription

React ha mejorado la gestión del estado con hooks incorporados como useState, useReducer y useRef. Redux todavía puede ser utilizado pero se recomienda evitar el estado global. Zustand es un gestor de estado alternativo que permite la fácil creación de hooks. La arquitectura adecuada es importante para acceder a la tienda global. Los gestores de estado pueden añadir bytes extra al paquete JavaScript del cliente, por lo que es importante ser selectivo al elegir las bibliotecas. Se recomiendan Next.js y los enrutadores React para la renderización del lado del servidor y se pueden lograr experiencias personalizadas con spas.

1. Introducción al Administrador de Estado

Short description:

Soy Jack Harrington, un ingeniero FullStack y YouTuber. Cubro React, la gestión de estado y el AppRouter en mi canal de YouTube llamado Blue Collar Coder. Aprendí de la experiencia y los comentarios y compartiré reglas pragmáticas para usar un administrador de estado de manera adecuada y segura.

Muy bien. Sí, soy Jack Harrington. No solo soy un ingeniero FullStack como muchos de ustedes, estoy seguro. También soy YouTuber. Así que tengo este canal de YouTube llamado Blue Collar Coder, y allí cubro una variedad de diferentes temas. Entonces, mucho de React, obviamente. Y hablo mucho sobre la gestión de estado. Así que cubro detalles en profundidad sobre eso, y hablo mucho sobre el AppRouter, porque está junto a la S y es muy popular, y es el nuevo router, y recibo muchos comentarios porque cubro muchas de estas cosas. Como, oye, ¿cómo uso mi tienda Redux en el AppRouter? Y yo estoy como, esa es una pregunta interesante. Así que hice un montón de codificación para ver por mí mismo, cómo lo haría. Y sabía en ese momento, estaba como, hmm, esto parece funcionar. Definitivamente funciona, pero tal vez esta no es la forma correcta. Así que saqué un video. Boom. Y en realidad lo hizo bastante bien. A la gente pareció gustarle por el lado de los comentarios. De hecho, cuando lo bajé, porque hay algunos anti-patrones en él, estaban como, ¿dónde se fue? Pero recibí algunos comentarios del equipo de React y del equipo de Next.js, como, ya sabes, hay algunas cosas que no deberías hacer allí. Así que lo que estoy aquí para hacer hoy es darles toda la experiencia que aprendí de eso. Volví y hice mucha más codificación, obtuve muchos más comentarios. Y lo que espero presentarles hoy son algunas reglas pragmáticas básicas sobre cómo usar un administrador de estado de manera adecuada y segura. Y tal vez si deberías o no en el App Writer.

2. Gestión de Estado en React y Consejos de Seguridad para Redux

Short description:

React ha mejorado la gestión de estado con hooks incorporados como useState, useReducer y useRef. Next.js también proporciona opciones de gestión de estado como route state y searchParamsState. Esto significa que es posible que no necesites un administrador de estado separado. Sin embargo, si aún quieres usar Redux, aquí tienes un consejo de seguridad: evita el estado global.

Y es interesante, volvamos al principio de todo esto. Así que el pensamiento común en torno a React ha sido... Quiero decir, solo ha existido durante diez años. Pero durante la mayor parte de ese tiempo, o gran parte de él, hemos tenido los componentes de clase, y this.state y this.setState. Y eso no era genial, desde un punto de vista de gestión de estado. Por eso te encuentras con cosas como Redux, MobX, para hacerlo una mejor experiencia.

Pero ahora, tienes que pensar de manera diferente al respecto. Porque tenemos una mejor gestión de estado incorporada directamente en React. Tienes useState, useReducer, useRef para almacenar un estado. Tienes useCallback, useMemo, useEffect para escuchar los cambios en los estados. Y eso es básicamente un sistema de gestión de estado reactivo incorporado directamente en el núcleo de React. Así que tal vez no necesitamos un administrador de estado.

Y luego, encima de eso, tenemos Next.js, y el operador tiene el estado de ruta. Tienes las rutas parametrizadas, tienes los parámetros, tienes searchParamsState. Si miras a Lee Robinson, hizo un fantástico video recientemente sobre cómo usar searchParamsState para mantener el estado y gestionar el estado en una aplicación Next.js. Tienes el estado del formulario, tienes acciones del servidor, tienes revalidación, puedes hacer cosas como HTMX y tener desarrollo impulsado por el servidor. Así que el resultado final es la regla número 0, es posible que no necesites un administrador de estado. Así que piensa en eso primero. Cuando pienses en tu nuevo proyecto o en migrar, sabes, tal vez un administrador de estado no va a ser parte de eso.

Es raro. Vienes con una charla sobre gestión de estado, y soy el tipo que te dice que tal vez no necesites un administrador de estado. Pero tal vez estás como, oh, estoy realmente triste. Amo mi administrador de estado. Me encanta cómo funciona. No quiero hacer matrices de dependencia. Así que está bien. Permíteme darte algunos consejos de seguridad para hacerlo de manera segura si aún quieres usar una tienda Redux. Así que la regla número 1, no hay estado global. ¿Qué quiero decir con eso? Bueno, está bien, pensemos en un global. Tienes tu tienda de configuración aquí.

React is a library for "rendering" UI from components, but many users find themselves confused about how React rendering actually works. What do terms like "rendering", "reconciliation", "Fibers", and "committing" actually mean? When do renders happen? How does Context affect rendering, and how do libraries like Redux cause updates? In this talk, we'll clear up the confusion and provide a solid foundation for understanding when, why, and how React renders. We'll look at: - What "rendering" actually is - How React queues renders and the standard rendering behavior - How keys and component types are used in rendering - Techniques for optimizing render performance - How context usage affects rendering behavior| - How external libraries tie into React rendering

When we think about Vuex, Pinia, or stores in general we often think about state management and the Flux patterns but not only do stores not always follow the Flux pattern, there is so much more about stores that make them worth using! Plugins, Devtools, server-side rendering, TypeScript integrations... Let's dive into everything beyond state management with Pinia with practical examples about plugins and Devtools to get the most out of your stores.

Can useEffect affect your codebase negatively? From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much. In this talk, we'll demystify the useEffect hook and get a better understanding of when (and when not) to use it, as well as discover how declarative effects can make effect management more maintainable in even the most complex React apps.

Ivan’s first attempts at performance debugging were chaotic. He would see a slow interaction, try a random optimization, see that it didn't help, and keep trying other optimizations until he found the right one (or gave up).
Back then, Ivan didn’t know how to use performance devtools well. He would do a recording in Chrome DevTools or React Profiler, poke around it, try clicking random things, and then close it in frustration a few minutes later. Now, Ivan knows exactly where and what to look for. And in this workshop, Ivan will teach you that too.
Here’s how this is going to work. We’ll take a slow app → debug it (using tools like Chrome DevTools, React Profiler, and why-did-you-render) → pinpoint the bottleneck → and then repeat, several times more. We won’t talk about the solutions (in 90% of the cases, it’s just the ol’ regular useMemo() or memo()). But we’ll talk about everything that comes before – and learn how to analyze any React performance problem, step by step.
(Note: This workshop is best suited for engineers who are already familiar with how useMemo() and memo() work – but want to get better at using the performance tools around React. Also, we’ll be covering interaction performance, not load speed, so you won’t hear a word about Lighthouse 🤐)

With the release of React 18 we finally get the long awaited concurrent rendering. But how is that going to affect your application? What are the benefits of concurrent rendering in React? What do you need to do to switch to concurrent rendering when you upgrade to React 18? And what if you don’t want or can’t use concurrent rendering yet?

There are some behavior changes you need to be aware of! In this workshop we will cover all of those subjects and more.

Join me with your laptop in this interactive workshop. You will see how easy it is to switch to concurrent rendering in your React application. You will learn all about concurrent rendering, SuspenseList, the startTransition API and more.

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.

ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.

The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.

React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way we'll show test-driven development and emphasize tips-and-tricks in the IDE.

React Testing Library is a great framework for React component tests because there are a lot of questions it answers for you, so you don’t need to worry about those questions. But that doesn’t mean testing is easy. There are still a lot of questions you have to figure out for yourself: How many component tests should you write vs end-to-end tests or lower-level unit tests? How can you test a certain line of code that is tricky to test? And what in the world are you supposed to do about that persistent act() warning?
In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn
