Demostraremos cómo Three.js se está adaptando para aprovechar todo su potencial, desbloqueando oportunidades sin precedentes para que los desarrolladores creen experiencias interactivas visualmente impresionantes. Transicionando al ámbito inmersivo, profundizamos en WebXR, una tecnología que abre la puerta a experiencias de realidad virtual y realidad aumentada directamente desde la web. Mostraremos cómo Three.js permite a los creadores construir experiencias inmersivas.

Embracing WebGPU and WebXR With Three.js

The 3JS project has evolved into a community-driven effort with numerous contributors over the past 14 years. It started with 3D engine work in Flash and transitioned to using SVGs for rendering in HTML5 before adopting WebGL. The project showcases various projects and frameworks, including a no-code tool powered by 3.js. The team is working on a new render using WebGPU and developing a new shader language called TSL. The hope is that WebGPU will eventually replace WebGL, offering better control and performance.

In the rapidly evolving landscape of web technologies, the introduction of WebGPU and WebXR represents a significant leap forward, promising to redefine the boundaries of what's possible in 3D web experiences. This talk dives into the heart of these new technologies, guided by the Three.js library. We begin by exploring WebGPU, a next-generation graphics API offering enhanced performance and efficiency for rendering 3D graphics directly in the browser. We'll demonstrate how Three.js is adapting to harness its full potential, unlocking unprecedented opportunities for developers to create visually stunning interactive experiences. Transitioning to the immersive realm, we delve into WebXR, a technology that opens the door for virtual reality and augmented reality experiences right from the web.

En esta charla, echaremos un vistazo a una biblioteca de javascript idiosincrásica, htmx, que está diseñada para hacer que HTML sea más poderoso como hipermedia. Lo hace generalizando la idea de controles de hipermedia como etiquetas de anclaje y formularios. Los desarrolladores web que usan htmx generalmente no escriben tanto javascript como lo harían si eligieran una biblioteca de javascript SPA más popular para sus necesidades de front-end. De esta manera, htmx puede ayudar a abordar la "Fatiga de JavaScript", una sensación general de estar abrumado por el mundo de JavaScript. A veces se considera a htmx como una biblioteca "para personas que odian JavaScript". Irónicamente, sin embargo, al reducir drásticamente la cantidad de JavaScript que un desarrollador web debe escribir para construir una aplicación web, htmx puede hacer que el JavaScript que un desarrollador quiera escribir sea mucho más agradable, convirtiendo la escritura de JavaScript en una parte divertida, valiosa y lúdica de una aplicación web más amplia en lugar de una tarea que debe realizarse para llevar a cabo tareas simples.

htmx Es Pro-JavaScript

HTMX is a JavaScript library that extends HTML and works with a JSON API. It generalizes the functionality of links and forms, making any element a potential hypermedia control. HTMX simplifies the implementation of hypermedia functionality with a dozen core attributes. It can achieve powerful UI results without writing much JavaScript. HTMX complements JavaScript libraries and enhances user experience by providing functionality that the browser lacks.

In this talk we will take a look at an idiosyncratic javascript library, htmx, which is designed to make HTML more powerful as a hypermedia. It does this by generalizing the idea of hypermedia controls such as anchor tags and forms. Web developers who use htmx typically do not write nearly as much javascript as they would if they chose a more popular SPA javascript library for their front end needs. In this way, htmx can help address "JavaScript Fatigue", a general sense of being overwhelmed by the JavaScript world. htmx is sometimes held up as a library "for people who hate JavaScript". Ironically, however, by dramatically reducing the amount of JavaScript a web developer must write to build a web application, htmx can make the JavaScript that a developer wants to write much more enjoyable, making writing JavaScript a playful, high-value and fun part of a broader web application rather than a chore that must be dealt with to accomplish simple tasks.

htmx Is Pro-JavaScript

Evan Seaward

Uno de los problemas más comunes en las bases de código de JavaScript es que nuestro código es demasiado complejo. A medida que los proyectos y sus requisitos evolucionan, la complejidad se infiltra. La complejidad excesiva ralentiza el progreso, frustrándonos mientras intentamos mantener grandes porciones de un programa en nuestra mente solo para entender lo que está sucediendo. ¡Para conquistar la complejidad, debemos refactorizar! En esta charla, investigaremos cómo identificar la complejidad innecesaria en nuestra base de código utilizando la complejidad cognitiva como medida, cómo abordar la refactorización de código complejo y qué herramientas están disponibles para ayudarnos a refactorizar. Lo pondremos todo en práctica a través de un ejemplo en vivo. Al final de la charla, estarás emocionado de abordar esa monstruosidad de función de 1000 líneas en tu propia base de código (sabes cuál).

Conquistando la Complejidad: Refactorización de Proyectos JavaScript

Today's Talk explores the complexity in code and its impact. It discusses different methods of measuring complexity, such as cyclomatic complexity and cognitive complexity. The importance of understanding and conquering complexity is emphasized, with a demo showcasing complexity in a codebase. The Talk also delves into the need for change and the role of refactoring in dealing with complexity. Tips and techniques for refactoring are shared, including the use of language features and tools to simplify code. Overall, the Talk provides insights into managing and reducing complexity in software development.

One of the most common issues in JavaScript code bases is that our code is too complex. As projects and their requirements evolve, complexity creeps in. Excess complexity slows progress, frustrating us as we try to keep large chunks of a program in our heads just to understand what is happening. To conquer complexity, we must refactor! In this talk, we'll investigate how to identify unnecessary complexity in our code base using cognitive complexity as a measure, how to approach refactoring complex code, and what tools are available to help us refactor. We'll put it all into practice through a live example. By the end of the talk, you'll be excited to tackle that 1000-line monstrosity of a function in your own code base (you know the one).

Pruebas: Haz más con menos

This talk focuses on practical approaches for testing Node.js applications, including the use of Dora metrics and the testing trophy strategy. It emphasizes the importance of covering critical flows with integration and end-to-end tests, while also considering the cost and speed of different test types. The speaker recommends mocking third-party services and using snapshot testing, but warns about the potential for false positives. Playwright is suggested as a preferred tool, and the importance of automated test execution is emphasized.

How can you be confident that your code is well-tested? For me, the criteria are straightforward: you feel comfortable deploying it automatically to production on a Friday evening, and the release pipeline stays as green as an evergreen tree. In this talk, I'll share some approaches that I am following to hit both targets for Node.js apps (APIs, BFFs, etc).

Comprende los fundamentos de la tecnología NFT y su aplicación en el fortalecimiento de la seguridad web. A través de demostraciones prácticas y ejercicios prácticos, los asistentes aprenderán cómo integrar sin problemas mecanismos de control de acceso basados en NFT en sus proyectos de desarrollo front-end.

Cómo Construir Control de Acceso Front-End con NFTs

Welcome everyone! Today we are talking about unlocking digital ownership and starting accounts using blockchain technology. NFTs are unique digital assets based on blockchain technology. Blockchain provides transparency and immutability. To get started with blockchain, you need to install a wallet, specifically the MetaMask extension for Chrome. To enable your wallet, share your wallet address with others to receive money. To obtain tokens for testing, we will use a workshop faucet that provides test tokens. To create an NFT, we will use the Remix online environment. We mint a new token to the sender, and this is the unique ID of the asset in the collection. To create a project, use the command provided and specify the project name. To configure the Next.js to use my image, create a dotenv file with the smart contract address. You can have basic or VIP access and unlock content using NFTs. Update the main page by connecting the wallet, granting access, and minting an NFT. Create a new account and connect it to the wallet. Access someone else's token and content. Recap of creating basic smart content using Solidity. Exploring the possibilities and use cases of NFTs, including their use in sports, gaming, and real estate. Exploring the unique nature of NFTs, their various types, and the importance of transaction validation and fees in blockchain networks. Exploring other blockchains compatible with Ethereum, their benefits, and the importance of transaction fees in blockchain networks. Thank you for attending the workshop and interacting with me.

Understand the fundamentals of NFT technology and its application in bolstering web security. Through practical demonstrations and hands-on exercises, attendees will learn how to seamlessly integrate NFT-based access control mechanisms into their front-end development projects.

El siempre creciente panorama de aplicaciones de JavaScript ha llegado ahora a la gran pantalla, sí, lo has oído bien, ¡puedes construir apps de TV con JavaScript! El espacio operativo de las TVs es un desastre; hay más fragmentación que en el ecosistema de Android, y eso ya es decir algo. Cada fabricante ha tratado de reinventar la rueda creando su propio sistema operativo. En este momento, los principales actores son Android TV, tvOS, WebOS, Tizen, entre muchos otros. Esto lo convierte en un lugar único donde JavaScript y las tecnologías web pueden convertirse en un factor unificador y ahorrarte el estrés de tratar de desarrollar y mantener un montón de apps para la gran pantalla. Hablaremos sobre cómo construir apps de TV, qué frameworks de JS pueden ayudar en esto, y exploraremos los desafíos que vienen de la mano con el desarrollo de apps de TV, como los cuellos de botella de rendimiento y la gestión del enfoque utilizando los controles remotos.

JavaScript en la Gran Pantalla: Creando Apps de TV

JavaScript is widely used in web, mobile, and backend development, and now it is also being used to create TV apps. TVs with web-based operating systems can be targeted with JavaScript applications, and React is commonly used for TV app development. React Native allows for cross-platform TV app development, except for Roku. User interactions and focus management are important considerations in TV app development. Performance optimization is crucial for TV apps, as TVs have lower device scores and limited RAM. Spatial virtualization can significantly improve TV app performance.

The ever-expanding landscape of JavaScript applications has now reached the big screen - yes, you heard it right, you can build TV apps with JavaScript!  The TV operating space is a mess; there’s more fragmentation than the Android ecosystem, and that’s saying something. Each manufacturer has tried to reinvent the wheel by making their own OS. At the moment, the main players are Android TV, tvOS, WebOS, Tizen, among a whole myriad of others.  This makes it a unique place where Javascript and web technologies can become a uniting factor and save you from the stress of trying to develop and maintain handfuls of apps for the big screen.  We’ll talk about how to build TV apps, what JS frameworks can help in this, and explore the challenges that come hand-in-hand with TV app development, namely performance bottlenecks and focus management using remote controls.

JS on the Big Screen: Making TV Apps

La cruda realidad es que el desarrollo de software es desordenado. Comienzas con las mejores herramientas, la mejor arquitectura y las mejores intenciones, pero la calidad inevitablemente decae con el tiempo. El código frontend es particularmente frágil en el tiempo, ya que se encuentra en la intersección de producto, diseño e ingeniería. Hace un tiempo comencé a preguntarme si todas las bases de código están destinadas a fallar y volverse obsoletas. Luego comencé a recopilar lecciones de éxitos y fracasos pasados y noté cuán importante era la resiliencia para el éxito de un proyecto a largo plazo. La resiliencia es la capacidad de una base de código para sobrevivir a oleadas de desarrollo caótico y cambios no planificados. La resiliencia tiene menos que ver con las herramientas y frameworks que implementas, y más que ver con la disciplina de escribir y mantener un código limpio. ¿Alguna vez te has preguntado cuánto trabajo se requerirá para actualizar el código que estás escribiendo hoy, dentro de 6 meses? Veamos si podemos responder eso con un simple: "no mucho".

Lecciones para Construir Bases de Código Resilientes

Code bases degrade over time, so it's important to build a protective layer and accept imperfections. Collocation and leaving traces in the code are key for better understanding. TypeScript's strict null checks and explicit typing can improve code reliability. Guidelines and naming conventions are crucial for maintaining a consistent and scalable architecture. Version control complexity is not significantly affected by having multiple components in one file.

The harsh reality is that software development is messy. You start with the best tools, the best architecture and the best intentions, but quality inevitably degrades over time. Frontend code is particularly fragile in time as it sits at the intersection of product, design and engineering. A while ago I started asking myself if all codebases are destined to fail and become legacy or obsolete. Then I began collecting lessons from past wins and failures and noticed how important resilience was to the success of a long term project. Resilience is the ability of a codebase to survive through waves of chaotic development and unplanned changes. Resilience has less to do with the tools and frameworks you deploy, and more to do with the discipline of writing and maintaining clean code. Have you ever wondered how much work will be required to update the code you are writing today, 6 months from now? Let's see if we can answer that with a simple: "not too much".

Entre los core-web vitals y las herramientas de perfilado siempre hay un gran obstáculo, la aprobación de la empresa. Hay muchas formas en las que tu trabajo de rendimiento puede no ser visto o priorizado. Así que hablemos de ellas.

Por qué tu trabajo de rendimiento no es visible

This Talk discusses the importance of performance work and how to drive performance governance. It emphasizes the need to frame data, set meaningful budgets, and understand both engineering and product perspectives. The Talk also highlights the significance of delivering value, establishing solid performance governance, and gaining buy-in from management. Additionally, it emphasizes the importance of measuring performance, optimizing through data, and collecting performance data using tools like Speedcurve and Bugbear Sentry. The speaker also mentions their training program and expresses gratitude towards the audience.

Between core-web vitals and profiling tools there's always one big obstacle, company buy-in. There are many ways your performance work might not be seen or prioritised. So let's talk about them.

Why Your Performance Work Is Not Seen

En esta charla, discutimos y obtenemos una introducción a Web5, una plataforma web descentralizada de código abierto que devuelve la propiedad y el control sobre los datos a los individuos, donde pertenecen. Lo hace proporcionando una nueva capa para la web que permite a los desarrolladores construir aplicaciones y protocolos descentralizados.

Construyendo una Web Descentralizada con Web5

Today's Talk introduces Web5, which combines the best of Web 2 and Web 3 to build a decentralized web. Web5 consists of three pillars: decentralized identifiers, verifiable credentials, and decentralized applications. Verifiable credentials are used on platforms like LinkedIn, while decentralized web nodes act as data stores for web apps. Web5 allows users to own their data, reduces friction in onboarding, and enables example applications like Universal Music Playlist and Connected Travel. Building for Web5 presents challenges such as key management and data usage, but there are resources available to learn more about the technologies.

In this talk, we discuss and get an introduction into Web5, an open source decentralized web platform that returns ownership and control over data to individuals where it belongs. It does this by providing a new layer for the web that enables developers to build decentralized applications and protocols.

¿Alguna vez te has preguntado cómo interactúan los lectores de pantalla con los navegadores para proporcionar experiencias accesibles? Es posible que hayas escuchado términos como "APIs de accesibilidad", "árbol de accesibilidad" o "cálculo del nombre accesible". Pero, ¿a qué se refieren realmente?En esta charla, desmitificaremos el proceso en el que los navegadores generan y actualizan el árbol de accesibilidad. Analizaremos sus elementos clave y cómo los elementos HTML y los atributos ARIA se mapean en él. Por último, exploraremos cómo los desarrolladores web pueden aprovecharlo para una depuración efectiva. ¡Sumérgete en el funcionamiento interno de las interacciones entre lectores de pantalla y navegadores!

¿Qué es el Árbol de Accesibilidad, en realidad?

This is a presentation on accessibility and screen readers. The speaker discusses the evolution of screen readers and how they adapted to graphical user interfaces. Accessibility APIs and the accessibility tree are introduced, allowing programs to construct a text database used by assistive technologies. The accessibility tree may vary across browsers and platforms, excluding elements that are not relevant to assistive technologies. The ARIA hidden state and element properties play a role in determining the accessibility of elements, and the accessible name can be derived from text content or specified using ARIA attributes.

Have you ever wondered how screen readers interact with browsers to provide accessible experiences? You may have heard terms like "accessibility APIs", “accessibility tree” or "accessible name computation". But what do they refer to, really? In this talk, we will demystify the process in which browsers generate and update the accessibility tree. We will look into its key elements, and how HTML elements and ARIA attributes map into it. Lastly, we will explore how web developers can leverage it for effective debugging. Let's dive into the inner workings of screen readers-browsers interactions!
