JavaScript en el navegador se ejecuta muchas veces más rápido de lo que lo hacía hace dos décadas. Y eso sucedió porque los proveedores de navegadores pasaron ese tiempo trabajando en intensivas optimizaciones de rendimiento en sus motores JavaScript.Debido a este trabajo de optimización, JavaScript ahora se está ejecutando en muchos lugares además del navegador. Pero todavía hay algunos entornos donde los motores JS no pueden aplicar esas optimizaciones de la manera correcta para hacer las cosas rápidas.Estamos trabajando para resolver esto, comenzando una nueva ola de trabajo de optimización de JavaScript. Estamos mejorando el rendimiento de JavaScript para entornos completamente diferentes, donde se aplican reglas diferentes. Y esto es posible gracias a WebAssembly. En esta charla, explicaré cómo funciona todo esto y qué vendrá a continuación.

Haciendo JavaScript en WebAssembly Rápido

WebAssembly enables optimizing JavaScript performance for different environments by deploying the JavaScript engine as a portable WebAssembly module. By making JavaScript on WebAssembly fast, instances can be created for each request, reducing latency and security risks. Initialization and runtime phases can be improved with tools like Wiser and snapshotting, resulting in faster startup times. Optimizing JavaScript performance in WebAssembly can be achieved through techniques like ahead-of-time compilation and inline caching. WebAssembly usage is growing outside the web, offering benefits like isolation and portability. Build sizes and snapshotting in WebAssembly depend on the application, and more information can be found on the Mozilla Hacks website and Bike Reliance site.

JavaScript in the browser runs many times faster than it did two decades ago. And that happened because the browser vendors spent that time working on intensive performance optimizations in their JavaScript engines.Because of this optimization work, JavaScript is now running in many places besides the browser. But there are still some environments where the JS engines can’t apply those optimizations in the right way to make things fast.We’re working to solve this, beginning a whole new wave of JavaScript optimization work. We’re improving JavaScript performance for entirely different environments, where different rules apply. And this is possible because of WebAssembly. In this talk, I'll explain how this all works and what's coming next.

Casi todos los desarrolladores piensan que agregar una línea de registro más no disminuiría el rendimiento de su servidor... ¡hasta que el registro se convierte en el mayor cuello de botella para sus sistemas! Creamos uno de los registradores JSON más rápidos para Node.js: pino. Una de nuestras decisiones clave fue eliminar todo el "transporte" a otro proceso (o infraestructura): redujo tanto el consumo de CPU como de memoria, eliminando cualquier cuello de botella del registro. Sin embargo, esto creó fricción y disminuyó la experiencia del desarrollador al usar Pino y los transportes en el proceso es la característica más solicitada por nuestro usuario.En la próxima versión 7, resolveremos este problema y aumentaremos el rendimiento al mismo tiempo: estamos introduciendo pino.transport() para iniciar un hilo de trabajo que puedes usar para transferir tus registros de forma segura a otros destinos, sin sacrificar ni el rendimiento ni la experiencia del desarrollador.

Registro Multihilo con Pino

Today's Talk is about logging with Pino, one of the fastest loggers for Node.js. Pino's speed and performance are achieved by avoiding expensive logging and optimizing event loop processing. It offers advanced features like async mode and distributed logging. The use of Worker Threads and Threadstream allows for efficient data processing. Pino.Transport enables log processing in a worker thread with various options for log destinations. The Talk concludes with a demonstration of logging output and an invitation to reach out for job opportunities.

Almost every developer thinks that adding one more log line would not decrease the performance of their server... until logging becomes the biggest bottleneck for their systems! We created one of the fastest JSON loggers for Node.js: pino. One of our key decisions was to remove all "transport" to another process (or infrastructure): it reduced both CPU and memory consumption, removing any bottleneck from logging. However, this created friction and lowered the developer experience of using Pino and in-process transports is the most asked feature our user.In the upcoming version 7, we will solve this problem and increase throughput at the same time: we are introducing pino.transport() to start a worker thread that you can use to transfer your logs safely to other destinations, without sacrificing neither performance nor the developer experience.

La forma en que escribimos JavaScript en 2030 será completamente diferente a como lo hacíamos en 2020. Aquí está el por qué: la lenta muerte de IE11 y el despliegue de los módulos ES convergerán hacia una nueva generación de herramientas de JavaScript. Estas herramientas son más rápidas, más seguras en cuanto a tipos y políglotas, lo que conduce a una mejor experiencia tanto para el desarrollador como para el usuario. ¡El cambio está en marcha!

La Tercera Edad de JavaScript

This talk presents the Third Age of JavaScript, covering the evolution and future of the language. It explores the adoption of ES modules and the decline of IE11, as well as the changing landscape of JavaScript tooling and the concept of polyglot tooling. The talk also touches on the potential future of JavaScript with WebAssembly and emphasizes the importance of code composability and receiving feedback in software development.

The way we write JavaScript in 2030 will be completely different than in 2020. Here's why: the slow death of IE11 and rollout of ES Modules will converge toward a new generation of JavaScript tooling. These tools are faster, typesafer, and polyglot, leading to both a better developer and user experience. Change is afoot!

La autenticación y autorización son problemas serios. A menudo dedicamos mucho tiempo a crear APIs poderosas pero pasamos por alto las medidas de seguridad adecuadas. Vamos a resolverlo con Magic utilizando una solución de identidad basada en claves sobre el estándar DID, donde las identidades de los usuarios son soberanas y se aprovechan de los pares de claves públicas y privadas de la cadena de bloques. En esta charla, veremos las formas adecuadas de asegurar nuestras APIs de Node.js con Tokens de Identidad Descentralizados. Pasaremos desde aprender qué son los estándares de Identidad Descentralizada, cómo las identidades de los usuarios son soberanas y se aprovechan de los pares de claves públicas y privadas de la cadena de bloques, por qué son el futuro de la seguridad de las APIs, y para poner en práctica la teoría construiremos una implementación real utilizando Node.js donde mostraré las mejores prácticas comunes. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Asegurando APIs de Node.js con Tokens de Identidad Descentralizados

This talk introduces the concept of securing a Node.js API using a decentralized identity token. The token is encoded as a Base64 string and consists of a proof and claim. The API is built using Express and protected using Magic. The application has multiple routes, with the secret route being protected by middleware. The authorization header is checked and the DID token is validated for access to protected routes.

Authentication and Authorization are serious problems. We often dedicate a lot of time to craft powerful APIs but overlook proper security measures. Let's solve it with Magic using a key-based identity solution built on top of DID standard, where users’ identities are self-sovereign leveraging blockchain public-private key pairs. In this talk, we’ll look at proper ways to secure our Node.js APIs with Decentralised Identity Tokens. We’ll go from learning what Decentralised Identity standards are, how the users’ identities are self-sovereign leveraging blockchain public-private key pairs, why they’re the future of API security, and to put theory into practice we will build a real-world implementation using Node.js where I’ll show common best practices. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Desde hace casi 25 años, los desarrolladores de JavaScript han sufrido a manos del tiempo: el objeto Date. Hemos intentado todo tipo de soluciones, desde el uso de bibliotecas populares como Moment.js hasta el manejo de fechas y horas en el backend.Ahora es el momento de mostrarle al "tiempo" quién manda. Con la API Temporal estable en la Etapa 3 y el polyfill listo para su uso en producción, permíteme mostrarte cómo aprovechar el poder de esta maravillosa API para construir aplicaciones JavaScript potentes que manejen fechas y horas como siempre quisimos. También discutiremos las características ortogonales que se están trabajando en la API JavaScript Intl y descubriremos cómo se complementan entre sí y se unen para formar un conjunto completo de APIs que nos permiten construir componentes de fecha y hora de última generación en nuestras aplicaciones. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Cómo superar al tiempo: Construyendo aplicaciones JavaScript futuristas utilizando Temporal

Temporal is a proposal in JavaScript that brings an ergonomic API for building futuristic JavaScript applications. It is now at stage 3 and implementers will start implementing it in different polyfills and browsers. Temporal includes classes for working with dates, times, time zones, calendars, and durations. The talk covers building an invoice calculator using Temporal, calculating durations between date times, creating and manipulating durations, understanding time relativity and rounding, and rewriting methods using Temporal. The speaker expresses gratitude to various contributors and provides a sandbox for exploration.

For close to 25 years now, JavaScript developers have suffered at the hands of time: the Date object. We have tried all sorts of solutions from using popular libraries like Moment.js all the way to handling dates and times on the backend.Now it's time to show "time" who is boss. With the Temporal API stable at Stage 3 and the polyfill ready for production use, let me show you how to harness the power of this delightful API in order to build powerful JavaScript applications that handle dates and times like we always wished we could. We shall also discuss the orthogonal features being worked on in the JavaScript Intl API and find out how these play along with each other and come together to form a comprehensive set of APIs that allow us to build state of the art date and time components in our applications. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Microfrontends con Module Federation y Angular

Microfrontends with module federation allow teams to develop and deploy separate parts of a system, simplifying integration into a common shell. Webpack 5 Module Federation solves the issue of loading separately compiled source code for microfrontends. Version mismatches in module federation can be handled using strategies and semantic versioning. Angular can be combined with module federation using a custom builder. Microfrontends can share data and libraries, and web components can be used to wrap and render components from different versions or frameworks. Module federation allows for version negotiation and runtime loading of microfrontends. React.js can be integrated with module federation, and web components can be used to share libraries across different applications. The bootstrap method and web components wrapper simplify the process of bootstrapping Angular applications and loading web components on demand.

Ever more companies are choosing Micro-Frontends. However, they are anything but easy to implement. Fortunately, Module Federation introduced with webpack 5 has initiated a crucial change of direction. In this interactive workshop, you will learn from Manfred Steyer -- Angular GDE and Trusted Collaborator in the Angular team -- how to plan and implement Micro-Frontend architectures with Angular and the brand new webpack Module Federation. We talk about sharing libraries and advanced concepts like dealing with version mismatches, dynamic Module Federation, and integration into monorepos. After the individual exercises, you will have a case study you can use as a template for your projects. This workshop helps you evaluate the individual options for your projects. Prerequisites:You should have some experience with Angular. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

CSS ha evolucionado y crecido enormemente desde que se introdujo por primera vez en 1996. Hubo un tiempo en aquel entonces en el que CSS ni siquiera estaba destinado a hacer diseños, pero ese tiempo ya pasó. Hoy en día, los diseños web son prácticamente sinónimo de CSS. Además de eso, CSS ahora se puede utilizar para construir cosas que antes solo eran posibles con JavaScript. Esta charla mostrará algunas de esas características y explicará cómo construirlas tú mismo. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

CSS También Puede Hacer Eso

This Talk is about CSS techniques that can simplify web development and eliminate the need for JavaScript. It covers topics such as responsive typography, flexible font sizing, CSS math functions, scroll snapping, sticky elements, and CSS masonry layout. The speaker emphasizes the importance of understanding how sticky elements work and highlights the potential bugs that can occur. CSS Masonry layout is discussed as a native solution for creating masonry grids in the browser. Overall, CSS provides flexible solutions for web styling and is an exciting tool for developers.

CSS has evolved and grown immensely since it was first introduced back in 1996. There was a time back then when CSS was not even meant for doing layouts, but that time has long past. Today, web layouts are practically synonymous with CSS. In addition to that, CSS can now be used to build things that used to only be feasible with Javascript. This talk will showcase a few of such features and explain how to build them yourself. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Si tu empresa es como las que he trabajado, tienes aplicaciones con siete diseños de botones diferentes, tres datepickers diferentes y una extraña colección de dropdowns que pueden o no ser accesibles. Una tendencia creciente para lidiar con esta inconsistencia es construir un sistema de diseño personalizado o una biblioteca de componentes. Básicamente, construyes La Única Forma™ de crear un datepicker para tu organización y pides al resto de tu empresa que se ajuste a tu nuevo sistema. Pero construir una biblioteca de componentes viene con muchos desafíos, como, ¿qué frameworks o bibliotecas deberías usar (si es que alguna)? ¿Cómo te aseguras de que tus componentes sean accesibles? ¿Y cómo distribuyes tus componentes para que toda tu empresa los pueda usar? En esta charla relámpago aprenderás cómo construir una biblioteca de componentes rápidamente basándote en una biblioteca como Kendo UI. Aprenderás consejos y trucos sobre cómo empezar y ejecutar, cómo personalizar componentes y cómo distribuir componentes en toda tu organización.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Construyendo una Biblioteca de Componentes Personalizada - Rápido

Today, I want to talk to you about building custom component libraries fast. Every company should have its own standard set of UI controls for consistency in design, technology, and accessibility. Companies shouldn't build the harder parts of those libraries themselves, such as date pickers and data grids. But as a software developer, your time is valuable. Building custom component libraries is a better use of your time than reinventing the wheel.

If your company is anything like the ones I’ve worked for, you have apps with seven different button designs, three different datepickers, and a bizarre collection of dropdowns that may or may not be accessible. A growing trend to deal with this inconsistency is to build a custom design system or component library. Essentially, you build The One Way™ to create a datepicker for your organization, and ask that the rest of your company to conform to your new system. But building a component library comes with a lot of challenges, like, which frameworks or libraries should you use (if any)? How do you make sure your components are accessible? And how to you distribute your components so your whole company can use them? In this lightning talk you’ll learn how to build a component library fast building on top of a library like Kendo UI. You’ll learn tips &amp; tricks on how to get up and running, how to customize components, and how to distribute components throughout your organization. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

En esta charla, aprenderás cómo funcionan estos ataques de intermediario en tu propio sitio, diferentes enfoques que puedes utilizar y cómo podrían reemplazar muchas de nuestras mejores prácticas actuales. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Service Workers: Cómo realizar un ataque de intermediario en tu propio sitio por diversión y beneficio

Service workers provide resilience and make sites faster by intercepting requests and responses, caching assets, and providing fallbacks. They can be used to show critical information when a site goes offline, cache pages for offline access, and improve performance. Service workers can also be used to build multi-page apps with more resilience and less complexity. Caching API responses and gradually adding more complex features are recommended when adopting service workers. Single-page apps are not always the best choice, and different approaches fit different use cases.

Service workers bring amazing new capabilities to the web. They make fully offline web apps possible, improve performance, and bring more resilience and stability to any site. In this talk, you'll learn how these man-in-the-middle attacks on your own site work, different approaches you can use, and how they might replace many of our current best practices. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¿Cuánto tiempo llevamos viendo películas sobre la realidad y lo emocionante que se ve! Es posible que no te hayas dado cuenta, pero la realidad virtual ya está en nuestras vidas, incluso en nuestros navegadores. Cada vez hay más formas de aplicar estas tecnologías. Echemos un vistazo a la RV y RA y veamos cómo se ven en la vida real.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¡Expandamos la Realidad!

I work as a front-end developer with experience in 3D tasks using WebGL and 3DS framework. Let's explore virtual reality and WebXR, which allows full immersion in a digital environment. In VR, we can explore virtual worlds, move and rotate within them, interact with objects, and even use VR for education. AR, augmented reality, is different from VR as it allows you to see the real world while also overlaying virtual objects. XR reality encompasses both VR and AR, and it's already a standard with good browser support.

How long have we been watching movies about reality and how exciting it looks! You may not have noticed, but virtual reality is already in our lives, even in our browsers. There are more and more ways to apply these technologies. Let's take a look at VR and AR and see how they look in real life. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Tanto los desarrolladores experimentados como los principiantes tienen la costumbre de saltar directamente a un framework o nueva tecnología que promete mucho, pero que también pasa por alto fundamentos importantes que, sin ellos, tienden a limitar el potencial de un sitio web o aplicación. Sin un conocimiento básico de HTML, podrías excluir involuntariamente a personas de conocer tu empresa a través de tu sitio web debido a una mala accesibilidad. Si no comprendes o simplemente tienes miedo de CSS, es más probable que agregues bibliotecas innecesarias encima de otras bibliotecas que solo aumentan el peso de la página, lo que afecta la velocidad de carga de tu aplicación. En esta charla, repasaremos algunas estrategias básicas de HTML y CSS que se pueden utilizar de inmediato junto con JavaScript, incluidos frameworks como React y Vue, que proporcionarán una serie de beneficios adicionales, como una mejor accesibilidad, un código más simple y formas de mejorar el SEO para que los motores de búsqueda como Google puedan comprender más fácilmente de qué trata tu página.

Deja de usar Javascript: Mejora tus habilidades con los fundamentos del desarrollo web

This Talk provides insights into web development fundamentals and the challenges faced in React setup. It emphasizes the importance of building a strong foundation with HTML and CSS, and highlights the significance of SEO and accessibility in website development. The Talk also discusses the value of HTML, lists, and simplicity in coding. Overall, it offers practical advice for developers to level up their skills in web development.

Seasoned and beginner alike, developers have a habit of jumping right into a framework or new technology that makes a lot of promises while also glazing over important fundamentals that without, tend to hold back a website or application’s potential. Without some basic knowledge of HTML, you might inadvertently exclude people from learning about your company through your website due to poor accessibility. Lacking an understanding or simply being afraid of CSS, you might be more prone to add unnecessary libraries on top of libraries that just add to the weight of the page, impacting how quickly your app can load. In this talk, we’ll go over some basic HTML and CSS strategies that can immediately be used right alongside of JavaScript including frameworks like React and Vue that will provide another range of benefits like better accessibility, simpler code, and ways you can improve SEO letting search engines like Google more easily figure out what your page is about.

Construye aplicaciones Fullstack en tiempo récord con Blitz.js

The speaker wanted to create the best developer experience for full stack React apps by simplifying the development process and getting rid of the API layer. They were inspired by server-side rendering in Ruby on Rails and wanted to achieve something similar with React. They announced Blitz with a server-side rendered prototype but wanted to improve it. They envisioned a simple solution where a server function talks directly to the database and is imported into the front-end code, with the framework handling the API layer.

Blitz.js is the Fullstack React Framework. It's heavily inspired Ru on Rails and is focused on making you as productive as possible. It's built on Next.js and adds all the missing pieces you need for building a fullstack app with a database. By far the biggest innovation of Blitz is the new "Zero-API" data layer that abstracts away the API so you don't have to mess with REST or GraphQL APIs! Brandon will cover all the important parts, so you'll know if you might want to use Blitz or not. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
