Los tutoriales interactivos basados en la web se han convertido en un elemento básico de los frameworks de front end, y es fácil ver por qué: a los desarrolladores les encanta poder probar nuevas herramientas sin el problema de instalar paquetes o clonar repositorios.Pero en la era de los meta-frameworks full stack como Next, Remix y SvelteKit, estos tutoriales solo llegan hasta cierto punto. En esta charla, veremos cómo nosotros, en el equipo de Svelte, estamos utilizando la tecnología web de vanguardia para repensar cómo nos enseñamos mutuamente las herramientas de nuestro oficio.

Documentación Full Stack

The Talk discusses the shift to full-stack frameworks and the challenges of full-stack documentation. It highlights the power of interactive tutorials and the importance of user testing in software development. The Talk also introduces learn.svelte.dev, a platform for learning full-stack tools, and discusses the roadmap for SvelteKit and its documentation.

Interactive web-based tutorials have become a staple of front end frameworks, and it's easy to see why — developers love being able to try out new tools without the hassle of installing packages or cloning repos.But in the age of full stack meta-frameworks like Next, Remix and SvelteKit, these tutorials only go so far. In this talk, we'll look at how we on the Svelte team are using cutting edge web technology to rethink how we teach each other the tools of our trade.

¿Qué haces cuando eres un framework que ha sobrevivido e innovado en dos Olas de Framework de JavaScript, y ves la nueva ola creciendo en la distancia? Innovas. En esta charla, exploramos el panorama del Framework de JavaScript, y algunas de las principales características competitivas que hemos visto. Exploraremos lo que Angular está introduciendo hoy y hacia dónde nos dirigimos en el futuro. <a href="https://www.froala.com/wysiwyg-editor?pb=1"></a>

El Viento y las Olas: La formación de Olas de Framework desde el Epicentro

Our understanding of innovation is wrong. Innovations are not introduced by a single point of light. The story of who invented the computer is not linear. Many steps forward led to the development of the computer. Angular has shaped and influenced multiple JavaScript waves, and Angular v14 simplifies development with standalone components.

What do you do when you're a framework that's survived and innovated in two JavaScript Framework Waves, and see the new wave cresting in the distance? You innovate. In this talk, we explore the JavaScript Framework landscape, and some of the major competitive features we've seen. We'll explore what Angular is introducing today and where we're headed in the future. <a href="https://www.froala.com/wysiwyg-editor?pb=1"></a>

¿Qué podemos aprender de los últimos 10 años para los próximos 5 años? ¿Hay un futuro para Webpack? ¿Qué necesitamos hacer ahora?

¿Webpack en 5 años?

In the last 10 years, Webpack has shaped the way we develop web applications by introducing code splitting, co-locating style sheets and assets with JavaScript modules, and enabling bundling for server-side processing. Webpack's flexibility and large plugin system have also contributed to innovation in the ecosystem. The initial configuration for Webpack can be overwhelming, but it is necessary due to the complexity of modern web applications. In larger scale applications, there are performance problems in Webpack due to issues with garbage collection, leveraging multiple CPUs, and architectural limitations. Fixing problems in Webpack has trade-offs, but a rewrite could optimize architecture and fix performance issues.

What can we learn from the last 10 years for the next 5 years? Is there a future for Webpack? What do we need to do now?

Webpack in 5 Years?

En esta charla mostraré Makepad, una nueva pila de UI que utiliza Rust, Wasm y WebGL. A diferencia de otras pilas de UI, que utilizan un enfoque híbrido, todo el renderizado en Makepad se realiza en la GPU. Esto permite aplicaciones altamente pulidas y visualmente impresionantes que hasta ahora no han sido posibles en la web. Debido a que Makepad utiliza Rust, las aplicaciones se ejecutan tanto de forma nativa como en la Web a través de wasm. Las aplicaciones de Makepad pueden ser muy pequeñas, del orden de solo unos pocos cientos de kilobytes para wasm, hasta unos pocos megabytes con nativo. Nuestro objetivo es desarrollar Makepad en la pila de UI de elección para aplicaciones multiplataforma ligeras y de alto rendimiento. Tenemos la intención de enviar con nuestra propia aplicación de diseño e IDE.

Makepad - Aprovechando Rust + Wasm + WebGL para construir aplicaciones multiplataforma increíbles

Welcome to MakePad, a new way to build UI for web and native using WebAssembly and Rust. JavaScript is not suitable for complex applications like IDEs and design tools. Rust, a new programming language, was used to reimagine MakePad, resulting in a fast and efficient platform. MakePad offers live editing, high CPU performance, and the ability to load native instrument components. The future of MakePad includes an open-source release, a design tool, and support for importing 3D models.

In this talk I will show Makepad, a new UI stack that uses Rust, Wasm, and WebGL. Unlike other UI stacks, which use a hybrid approach, all rendering in Makepad takes place on the GPU. This allows for highly polished and visually impressive applications that have not been possible on the web so far. Because Makepad uses Rust, applications run both natively and on the Web via wasm. Makepad applications can be very small, on the order of just a few hundred kilobytes for wasm, to a few megabytes with native. Our goal is to develop Makepad into the UI stack of choice for lightweight and performant cross-platform applications. We intend to ship with our own design application and IDE.

¿Sabes lo que es el síndrome del impostor, verdad!? Casi todos nosotros hemos sentido esa sensación persistente de que estamos fingiendo y que estamos seguros de ser descubiertos por todos los expertos que nos rodean en cualquier momento.Pero antes de que asumas que esta charla es la misma canción y baile lleno de platitudes que te animan a ignorar ese síndrome, permíteme darte una pequeña pista: no hay expertos a tu alrededor. El impostorismo no es un síndrome en absoluto, es una mentalidad y perspectiva pragmática, una que todos deberíamos abrazar y de la que deberíamos estar orgullosos. De hecho, es vital para que podamos hacer nuestro trabajo.

Confesiones de un Impostor

The Talk discusses imposter syndrome and reframes it as being a professional imposter. It emphasizes the importance of sharing and starting, embracing imposterism, and building inclusively for the web. The speaker shares personal experiences of being an imposter in various technical disciplines and highlights the significance of accessibility. The Talk concludes with the idea of building a collective RPG game to remove excuses for not making things accessible.

You know what impostor syndrome is, right!? Most all of us have felt that nagging feeling that we're faking it and that we're sure to be found out by all the experts around us at any moment.But before you go assuming this talk is the same ol' song and dance full of platitudes that encourage you to ignore that syndrome, let me clue you in on a little secret: there's no experts around you. Impostorism is not a syndrome at all, it's a pragmatic mindset and perspective, one we should all embrace and be proud of. In fact, it's vital to us getting our jobs done.

¡Nos encantan las aplicaciones web fáciles de crear y desplegar! Entonces, veamos qué puede hacer una pila tecnológica muy actual como Nuxt 3, Motion UI y Azure Static Web Apps. Podría ser perfectamente un trío de oro en el desarrollo web moderno. O podría ser una hoguera de errores y problemas. De cualquier manera, será una aventura de aprendizaje para todos nosotros. Nuxt 3 se lanzó hace apenas unos meses y no podemos esperar más para explorar sus nuevas características, como su compatibilidad con Vue 3 y el Motor Nitro. Agregamos un poco de estilo a nuestra aplicación con la biblioteca Sass Motion UI, porque el diseño estático está pasado de moda y las animaciones vuelven a estar de moda.Nuestra fuerza impulsora de la pila será Azure. Las aplicaciones web estáticas de Azure son nuevas, casi listas para producción y una forma ingeniosa y rápida para que los desarrolladores desplieguen sus sitios web. Así que, por supuesto, debemos probar esto.Con algunas Azure Functions esparcidas por encima, exploraremos lo que puede hacer el desarrollo web en 2022.

Embarcándonos en una aventura con Nuxt 3, Motion UI y Azure

The Workshop covered topics such as Nuxt3, Azure Static Web Apps, and Azure Functions. The participants created an insect encyclopedia-like application called Bucklopedia and deployed it to Azure. They also added styling, navigation, and functionality to the application. The workshop highlighted the ease of setting up a full-fledged API with Azure Functions and concluded with a successful deployment of the website.

We love easily created and deployed web applications! So, let’s see what a very current tech stack like Nuxt 3, Motion UI and Azure Static Web Apps can do for us. It could very well be a golden trio in modern day web development. Or it could be a fire pit of bugs and errors. Either way it will be a learning adventure for us all. Nuxt 3 has been released just a few months ago, and we cannot wait any longer to explore its new features like its acceptance of Vue 3 and the Nitro Engine. We add a bit of pizzazz to our application with the Sass library Motion UI, because static design is out, and animations are in again.Our driving power of the stack will be Azure. Azure static web apps are new, close to production and a nifty and quick way for developers to deploy their websites. So of course, we must try this out.With some sprinkled Azure Functions on top, we will explore what web development in 2022 can do.

a11y y TDD: Una Combinación Perfecta

This Talk explores the intersection of accessibility and test-driven development (TDD) in software development. TDD is a process that involves writing tests before writing production code, providing a safety net for code changes. The Talk demonstrates how to apply TDD principles to real-life examples, such as filling out a form, and emphasizes the importance of user-centric testing. By using atomic design principles, code can be organized in a clean and easy way. The Talk also discusses the use of labels and test IDs in tests for improved accessibility.

Accessibility has been web development's ugly duckling for quite some time now. I often get asked, "when should you test for a11y in your apps?" My answer is simple, "right from the start!". Regardless of the framework considered - React, Svelte, Vue, YourOwn™️ - as developers we are in a privileged position to help the ugly duckling grow into a beautiful swan. How? By diving deep into the pond and harnessing the power of Javascript APIs to build the right components for your web apps. And how can do you know you are building them right? By pairing Test Driven Development with the Testing Library family. Ready to grow your web apps into swans?

Node.js es genial: fácil de desarrollar, eficiente, fácil de escalar. Pero hay tareas que no son tan adecuadas para él, como cálculos pesados o procesamiento de datos. ¡Únete a mí y aprende cómo puedes incorporar Rust y WebAssembly en Node y JavaScript y llevar tu rendimiento al siguiente nivel!

🚀 Potencia tu NodeJS con Rust

In this Talk, Dmitry Kudravtsev discusses how to supercharge JavaScript and Node.js using Rust. He introduces NEON, an open-source library for integrating Rust and JavaScript, and explains how to use it to export Rust functions to JavaScript. Dmitry also explores the performance benefits of using native modules written in Rust and WebAssembly. He compares the two approaches and highlights the faster performance of Rust native modules. He concludes by recommending WebAssembly for its ergonomics and portability, while suggesting native modules for extending Node.js with performance code.

Node.js is great - easy to develop, performant, easy to scale. But there are tasks that are less suited for it - heavy computations or data processing. Join me and learn how you can incorporate Rust as well as WebAssembly into Node and JavaScript and take your performance to the next level!

¿Cuántas veces has dicho o escuchado 'esta es lógica de negocio, no debería estar aquí'?En este masterclass, crearemos una aplicación frontend moderna utilizando patrones antiguos y aprenderás cómo construir aplicaciones que tengan una interfaz de usuario y servicios desacoplados.Comenzaremos con una aplicación React que tiene toda su lógica en la interfaz de usuario. Luego, paso a paso, extraeremos las reglas y operaciones para alcanzar ese punto óptimo de independencia.

¿Deberíamos tener lógica de negocio en la interfaz de usuario?

The Workshop focused on developing a quiz game about the TV show 'Friends' using React and the Meet dependency. It emphasized the importance of separating UI and business logic, and implementing a layered architecture. The workshop also covered topics such as event handling, tracking, and audio integration. The use of typed events and the challenges of implementing game features like a lobby and character animations were discussed. Overall, the workshop provided valuable insights into software development best practices and performance optimization.

How many times did you say or hear “this is business logic, it should not be here”?In this workshop, we will create a modern frontend application using old patterns and you will learn how to build apps that have decoupled UI and services.We will start with a React application that has its whole logic in the UI. Then step by step we will extract the rules and operations to hit that sweet spot of independence.

Should we have business logic in the UI?

El desarrollo de aplicaciones web ha tenido muchos cambios a lo largo de la vida de la web. Desde aplicaciones del lado del servidor con un toque de JavaScript hasta aplicaciones de una sola página construidas completamente con JavaScript. Ahora estamos volviendo a donde muchos nuevos frameworks web se construyen primero de forma estática, con JavaScript agregado según sea necesario. Esta charla cubre la construcción de aplicaciones web con JavaScript a través de la lente de Astro, un generador de sitios estáticos donde la elección del framework de JavaScript es única para ti. <a href="https://www.froala.com/wysiwyg-editor?pb=1"></a>

La próxima ola de frameworks web es BYOJS

The next wave of web frameworks is BYOJS, covering the history and evolution of building web applications. The evolution of web frameworks and build systems includes popular choices like React, Angular, and Vue, as well as advanced build systems like Webpack and Rollup. The rise of performance measurement tools and the adoption of the Jamstack have led to improved web performance. The Jamstack architecture focuses on pre-rendering pages, decoupling APIs and services, and enhancing pages with JavaScript. Astro, a static site generator with SSR support, promotes the islands architecture and partial hydration.

Web application development has had many shifts over the lifetime of the web. From server-side applications with a sprinkle of JavaScript to Single Page Applications built entirely with JavaScript. Now we’re heading back to where many new web frameworks build for static first, with JavaScript added as needed. This talk covers building web applications with JavaScript through the lens of Astro, a static site generator where the choice of JavaScript framework is uniquely yours. <a href="https://www.froala.com/wysiwyg-editor?pb=1"></a>
