Separando la Separación de Preocupaciones
My concern is to accomplish my understanding of my concern. A to do app can have more than just managing tasks. Crosscutting concerns should be co-located. Separation of concerns is an effective technique for ordering thoughts. React is not slower than JS. React may be closer to a library with a concern of scheduling. Rerendering components too often is a problem in React. React is a state management library that helps in separating concerns and states, resulting in a more efficient and readable app. Proper separation of concerns, states, and components leads to smaller, faster, lighter, and more readable components.

Mantén la calma y despliégalo: Creando lanzamientos más seguros con Feature Flags
Feature flags can be used to mitigate risk in software development by altering the visibility of features to end users. By using flags, you can protect against single points of failure and pivot to a fallback service in worst-case scenarios. Monitoring and managing complexity is crucial, and using feature flags allows for dynamic changes and adjusting values based on proven correctness. Operating in the unknown is inevitable in software development, so it's important to manage complexity and embrace learning. Collaboration is key in making feature failures less painful.

Componentes del Servidor sin Tamaño de Paquete
React Server Components is a recent feature introduced with the React team and launched with Next.js 12. They allow for rendering components on the server, improving performance and data fetching. Server components can be used alongside client-side rendering and provide direct access to server resources. However, they are still in the experimental stage and have some limitations, such as not being able to use hooks or event handlers. Challenges include importing server components in client components and making third-party API calls.

Con el surgimiento de frameworks, como React, Vue o Angular, la forma en que se construyen los sitios web ha cambiado a lo largo de los años. Las aplicaciones modernas pueden ser muy dinámicas y realizar múltiples solicitudes de API para poblar un sitio web con contenido actualizado o enviar nuevos datos a un servidor. Sin embargo, este cambio de paradigma ha introducido nuevos problemas con los que los desarrolladores deben lidiar. Cuando una solicitud de API está pendiente, tiene éxito o falla, el usuario debe recibir una retroalimentación significativa. Otros problemas pueden incluir el almacenamiento en caché de datos de API o la sincronización del estado del cliente con el servidor. Todos estos problemas requieren soluciones que deben ser codificadas, pero pueden volverse rápidamente inmanejables y dar como resultado una base de código difícil de ampliar y mantener. En este masterclass, cubriremos cómo manejar las solicitudes de API, los estados de API y la cancelación de solicitudes mediante la implementación de una Capa de API y combinándola con React-Query.
Prerrequisitos: Para aprovechar al máximo este masterclass, debes estar familiarizado con React y Hooks, como useState, useEffect, etc. Si deseas codificar junto con nosotros, asegúrate de tener Git, un editor de código, Node y npm instalados en tu máquina.

Sabemos que React es para la web y React Native es para Android e iOS. Pero ¿has oído hablar de react-native-web, para escribir una aplicación para Android, iOS y la web en un solo código base? Al igual que React Native abstrae los detalles de iOS y Android, React Native Web también abstrae los detalles del navegador. Esto abre la posibilidad de compartir aún más código entre plataformas.En este masterclass, aprenderás a configurar el esqueleto de una aplicación React Native Web que funcione de manera excelente y se vea increíble. Puedes utilizar el código resultante como base para construir la aplicación que desees, utilizando los paradigmas de React y muchas bibliotecas de JavaScript a las que estás acostumbrado. ¡Te sorprenderá la cantidad de tipos de aplicaciones que realmente no requieren un código base separado para móvil y web!Aprenderás:- Configurar navegadores de cajón y de pila con React Navigation, incluyendo la capacidad de respuesta- Configurar React Navigation con URLs- Configurar React Native Paper, incluyendo el estilo del cajón de navegación y los encabezados de React Navigation- Configurar un tema de color personalizado que admita el modo oscuro- Configurar favicons/íconos de aplicaciones y metadatos- Qué hacer cuando no puedes o no quieres proporcionar la misma funcionalidad en la web y en el móvil
Prerrequisitos:- Familiaridad con la construcción de aplicaciones con React o React Native. No es necesario conocer ambos.- Configuración de la máquina: Node LTS, Yarn, ser capaz de crear y ejecutar correctamente una nueva aplicación Expo siguiendo las instrucciones en https://docs.expo.dev/get-started/create-a-new-app/

¿Estás satisfecho con tus suites de pruebas? Si dijiste que no, no estás solo, la mayoría de los desarrolladores no lo están. Y hacer pruebas en React Native es más difícil que en la mayoría de las plataformas. ¿Cómo puedes escribir pruebas en JavaScript cuando el código JS y nativo están tan entrelazados? ¿Y qué diablos se supone que debes hacer con esa persistente advertencia de act()? Ante estos desafíos, algunos equipos nunca logran avanzar en las pruebas de su aplicación de React Native, y otros terminan con pruebas que no parecen ayudar y solo requieren tiempo adicional para mantener.
Pero no tiene que ser así. React Native Testing Library (RNTL) es una excelente biblioteca para pruebas de componentes, y con el modelo mental adecuado puedes usarla para implementar pruebas de bajo costo y alto valor. En este taller de tres horas aprenderás las herramientas, técnicas y principios que necesitas para implementar pruebas que te ayudarán a lanzar tu aplicación de React Native con confianza. Saldrás con una visión clara del objetivo de tus pruebas de componentes y con técnicas que te ayudarán a superar cualquier obstáculo que se interponga en ese objetivo.aprenderás:- Los diferentes tipos de pruebas en React Native, y dónde encajan las pruebas de componentes- Un modelo mental para pensar en las entradas y salidas de los componentes que pruebas- Opciones para seleccionar elementos de texto, imagen y código nativo para verificar e interactuar con ellos- El valor de las simulaciones y por qué no se deben evitar- Los desafíos con la asincronía en las pruebas de RNTL y cómo manejarlos- Opciones para manejar funciones y componentes nativos en tus pruebas de JavaScript
Requisitos previos:- Familiaridad con la construcción de aplicaciones con React Native- Experiencia básica en la escritura de pruebas automatizadas con Jest u otro framework de pruebas unitarias- No necesitas experiencia previa con React Native Testing Library- Configuración de la máquina: Node 16.x o 18.x, Yarn, ser capaz de crear y ejecutar con éxito una nueva aplicación Expo siguiendo las instrucciones en https://docs.expo.dev/get-started/create-a-new-app/
