Setting up the system and separating concerns are important in software development. Modular construction and prefab units are a new trend that makes construction quicker and easier. Architectural complexity can lead to a drop in productivity and an increase in defects. Measuring architectural complexity can help identify natural modules in the code. Best practices for avoiding architectural complexity include organizing code by business domain and using prop drilling. Atomic design and organizing a monorepo are recommended approaches for managing architectural complexity.

El ecosistema de desarrolladores siempre está avanzando rápidamente y este año no ha sido una excepción. Los Componentes de Servidor React pueden ofrecer una mejora significativa a la experiencia del desarrollador y al rendimiento de la aplicación. Pero creo que es justo decir que este nuevo paradigma de servidor primero puede ser complicado de entender!En la primera mitad de esta masterclass, exploraremos los Componentes de Servidor React desde cero: construyendo nuestro propio mini marco meta para ayudarnos a entender cómo funcionan los RSCs. Descubriremos exactamente qué se produce en una construcción RSC y conectaremos esas piezas para formar una aplicación completa.A continuación, ¡lo desplegaremos! Cloudflare también ha tenido un año ocupado — Smart Placement, en particular, es una nueva tecnología que hemos desarrollado que se ajusta perfectamente al modelo RSC. Exploraremos por qué eso tiene sentido para nuestra aplicación de masterclass, y realmente lo desplegaremos en la Plataforma de Desarrolladores de Cloudflare.Finalmente, ampliaremos un poco más nuestra aplicación, utilizando D1 (nuestra base de datos SQL sin servidor) para mostrar realmente el poder del Componente de Servidor React cuando se combina con Smart Placement.Deberías salir de esta masterclass con una mayor comprensión de cómo funcionan los Componentes de Servidor React (tanto detrás de las escenas como también cómo tú como desarrollador puedes usarlos día a día), así como una visión de algunos de los nuevos patrones de despliegue que ahora son posibles después de las recientes innovaciones en el espacio de la plataforma.

Si eres como yo, probablemente tengas un millón de ideas para proyectos secundarios, algunas de las cuales incluso podrían hacerte ganar dinero como un micro SaaS, o podrían resultar ser la próxima startup de mil millones de dólares. Pero, ¿cómo sabes cuáles? ¿Cómo pasas de una idea a un producto funcional que puede ser puesto en manos de clientes que pagan sin renunciar a tu trabajo e invirtiendo todo tu tiempo y dinero en ello? ¿Cómo pueden competir tus proyectos secundarios en solitario con las aplicaciones construidas por enormes equipos y grandes empresas?
Construir productos SaaS ricos viene con desafíos técnicos como infraestructura, escalabilidad, disponibilidad, seguridad y subsistemas complicados como autenticación y pagos. Por eso, a menudo son los gigantes tecnológicos ya establecidos quienes pueden construir y operar productos de este tipo de manera razonable. Sin embargo, una nueva generación de devtools está permitiendo a los desarrolladores construir fácilmente soluciones completas que aprovechan la mejor infraestructura en la nube disponible, y ofrecen una experiencia que te permite iterar rápidamente en tus ideas por un bajo costo de $0. Se llevan todos los desafíos técnicos de construir y operar productos de software para que solo tengas que pasar tu tiempo construyendo las características que tus usuarios quieren, dándote una oportunidad razonable de competir contra el mercado al mantenerte increíblemente ágil y receptivo a las necesidades de los usuarios.
En esta masterclass de 3 horas comenzarás con una simple aplicación de gestión de tareas construida con React y Next.js y la convertirás en un producto SaaS completamente funcional y escalable integrando una base de datos escalable (PlanetScale), autenticación multi-tenant (Clerk), y pagos basados en suscripción (Stripe). También aprenderás cómo los principios del desarrollo de software ágil y el diseño impulsado por el dominio pueden ayudarte a construir productos rápidamente y de manera rentable, y competir con las soluciones existentes.

Managing complexity in large React applications is a challenge, as it tends to grow exponentially over time. Component composition is a key technique that allows for flexibility in React applications, but too much composition can make components harder to use. Managing complexity and reducing cognitive load is crucial, and strategies such as controlling abstraction evolution and minimizing information needed for simple changes can help. Simplicity is difficult, but important in slowing down the growth of complexity.

AI is revolutionizing application development and can enhance React applications. Advancements in AI include batch AI, real-time AI, and generative AI. Language models have limitations in accessing real-time data. Retrieval Augmented Generation (RAG) uses vectors to enhance language models. Vector search capabilities improve GPT models by providing up-to-date information and access to private data. Technologies like Next.js, OpenAI, Lankchain, Versel AI SDK, and MongoDB are used to build smarter React apps. An AI-powered documentation site can be built using custom data and vector search. The talk concludes by emphasizing the importance of integrating AI seamlessly into user-centric platforms like React-based projects.

Performance is a puzzle that requires different approaches for different problems and sites. User feedback is crucial in evaluating performance, rather than relying solely on metrics like Lighthouse scores. Measuring performance and identifying issues can be done through tools like the performance tab and user timings. Understanding the main thread and using tools like React Profiler and Chrome Tracing can provide insights into performance problems. Optimizing performance involves doing less work, avoiding main thread blocking, and considering options like virtualization and Canvas. Communicating the impact of optimization to leadership and exploring different uses of Canvas are also important topics discussed in the Talk.

This is a short presentation on VALTEO, a proxy-based state management system that uses JavaScript's native idea of proxies to create observable and immutable state. The proxy tracks changes to the object and nested proxy objects, only re-rendering the component when a specific key changes. There is a gotcha with proxies in Valtio - avoid reassigning the proxy to a whole new object. Valtio integrates with Redux DevTools, making it even more powerful and convenient.

Hi, I'm Annembae, the author of MillionJS, a fast virtual DOM replacement for React. The virtual DOM can be slow depending on the components it powers. The block virtual DOM introduces an O(1) optimization to the traditional virtual DOM, resulting in faster updates with fewer DOM manipulations. MillionJS and the Block Virtual DOM offer a faster alternative to existing virtual-dom libraries like React. It has the potential to revolutionize the way we write React applications.

Hey, everyone. Today, I want to talk about how anyone, even junior developers, can be an open-source maintainer. Let me share my journey of learning to code and becoming a maintainer. I made a website for an internal conference straight from code and made it open source. Participating in Hacktoberfest helped me connect with other developers and learn from them. Becoming an open-source maintainer increases your confidence, helps you make connections, and enables you to share cool tools with the world.

CDNs were introduced to improve website performance by bringing web content closer to users. The concept of the edge addresses the limitations of CDNs by processing client data close to the source. The edge combines serverless functions and CDNs, allowing for server-side logic execution without web server configuration. Use cases for the edge include personalization, geolocation-based content delivery, AV testing, and implementing security logic.
