TypeScript hace JavaScript más seguro agregando definiciones de tipo estático. Las definiciones estáticas son maravillosas; evitan que los desarrolladores cometan errores triviales asegurando que cada asignación e invocación se haga correctamente. Una variable tipificada como una cadena no puede ser asignada un número, y una función que espera tres argumentos no puede ser llamada con solo dos. Estas definiciones solo existen en el momento de la compilación; el código que finalmente se ejecuta es solo JavaScript. ¿Pero qué pasa con la respuesta de una solicitud de API? En esta charla, Ethan Arrowood, Ingeniero de Software 2 @ Microsoft, cubrirá varias soluciones para tipificar de manera segura los datos dinámicos en las aplicaciones TypeScript. Esta charla presenta tecnologías populares como Fastify, JSON Schema, Node.js, y más! <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Manejo Seguro de Datos Dinámicos con TypeScript

This Talk discusses the safe handling of dynamic data with TypeScript using JSON Schema and TypeBox. Fastify, a web framework, allows developers to validate incoming data using JSON schema, providing type safety and error handling. TypeBox is a powerful library that allows developers to define JSON schemas and derive static types in TypeScript. The combination of JSON schema, TypeBox, and Fastify provides powerful tools for type safety and validation of dynamic data.

TypeScript makes JavaScript safer adding static type definitions. Static definitions are wonderful; they prevent developers from making trivial mistakes ensuring every assignment and invocation is done correctly. A variable typed as a string cannot be assigned a number, and a function expecting three arguments cannot be called with only two. These definitions only exist at build time though; the code that is eventually executed is just JavaScript. But what about the response from an API request? In this talk Ethan Arrowood, Software Engineer 2 @ Microsoft, he will cover various solutions for safely typing dynamic data in TypeScript applications. This talk features popular technologies such as Fastify, JSON Schema, Node.js, and more! <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¿Cómo escalas una aplicación web para ser desarrollada por miles de ingenieros y actualizarla para utilizar las últimas tecnologías de JavaScript (Node.js + React)? ¡La respuesta es utilizando Micro Frontends!American Express es pionero en el uso de esta arquitectura, utilizándola en producción desde 2016 y transformando la cara de un sitio web utilizado por millones de usuarios en todo el mundo.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

La Revolución de los Micro Frontends en Amex

This Talk discusses the micro front-end revolution at American Express, highlighting the challenges of independent delivery and the solution of micro frontends. The architecture involves a Node.js server for server-side rendering and module composition, with Holocron modules deployed to a CDN. The development workflow includes local development environments and CI pipelines. Microfrontends are a pattern, not a set of tools, and should be implemented based on the specific use case. The adoption challenges include reworking the architecture and implementing features like Webpack and Module Federation. Communication between modules should be kept independent, and migration to micro frontends is simplified with existing microservices and Kubernetes. Server-side rendering is optional, and bundle size is limited to 250K.

How do you scale a web application to be developed thousands of engineers and upgrade it to use the latest Javascript technologies (Nodejs + React)? The answer is, using Micro-Frontends!American Express is a pioneer in the usage of this architecture using it in production since 2016 and transforming the face of a website used millions of users worldwide. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

El cliente HTTP de Node.js es una parte fundamental de cualquier aplicación, sin embargo, muchos piensan que no se puede mejorar. Tomé esto como un desafío y ahora estoy listo para presentar un nuevo cliente HTTP para Node.js, undici, que duplica el rendimiento de tu aplicación. La historia detrás de esta mejora comienza con el nacimiento de TCP/IP y está arraigada en una de las limitaciones fundamentales de las redes: el bloqueo de cabeza de línea (HOL blocking). El bloqueo de cabeza de línea es uno de esos temas que los desarrolladores ignoran felizmente y, sin embargo, afecta profundamente la experiencia de tiempo de ejecución de las aplicaciones distribuidas que construyen todos los días. Undici es un cliente HTTP/1.1 que evita el bloqueo de cabeza de línea utilizando keep-alive y pipelining, lo que resulta en una duplicación del rendimiento de tu aplicación.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¿Podemos duplicar el rendimiento del cliente HTTP?

Today's Talk discusses HTTP clients, servers, microservices, and maximizing performance in Node.js. It covers topics such as TCP, latency, HTTP Keep-Alive, pipelining, the Node.js event loop, timeouts, and introduces the Undici library. The speaker emphasizes the importance of reusing connections, minimizing blocking, and using benchmarks to measure performance impact. Undici is highlighted as a new client for Node.js that eliminates the need for multiple agents and offers easy configuration options.

The Node.js HTTP client is a fundamental part of any application, yet many think it cannot be improved. I took this as a challenge and I’m now ready to present a new HTTP client for Node.js, undici, that doubles the throughput of your application The story behind this improvement begins with the birth of TCP/IP and it is rooted in one of the fundamental limitations of networking: head-of-line blocking (HOL blocking). HOL blocking is one of those topics that developers blissfully ignore and yet it deeply impacts the runtime experience of the distributed applications that they build every day. Undici is a HTTP/1.1 client that avoids HOL blocking using keep-alive and pipelining, resulting in a doubling of your application throughput. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¿Cómo sabes si tu función está funcionando perfectamente en producción? Si algo se rompe en producción, ¿cómo lo sabrás? ¿Esperarás a que un usuario te lo informe? ¿Qué haces cuando los resultados de tus pruebas de preparación no reflejan el comportamiento actual de producción? ¡Para probar de manera proactiva en lugar de reactiva, prueba en producción! Tendrás una mayor precisión en los resultados de las pruebas, tus pruebas se ejecutarán más rápido debido a la eliminación de datos incorrectos y tendrás más confianza antes de los lanzamientos. Esto se puede lograr a través de la implementación de flags de características, lanzamientos canarios, configuración de un pipeline de CI/CD adecuado y limpieza de datos. Saldrás de esta charla con estrategias para mitigar riesgos, mejorar tu comprensión de los pasos necesarios y cambiar la cultura de pruebas de tu empresa, para poder brindar la mejor experiencia posible a tus usuarios. Al final del día, no nos importa si tus funciones funcionan en preparación, nos importa si funcionan en producción. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Usando Feature Flags para Habilitar Pruebas en Producción

Today's Talk discusses enabling tests in production, including challenges with staging environments, the use of feature flags for testing, and automating feature flag testing. It also covers running tests in production while ensuring no impact on real users, determining what to test in production, recommended tools and dependencies, and mitigating risks. The importance of testing in production and shifting the testing culture is emphasized, along with the need for a solid automation framework and managing feature flag dependencies.

How do you know your feature is working perfectly in production? If something breaks in production, how will you know? Will you wait for a user to report it to you? What do you do when your staging test results do not reflect current production behavior? In order to test proactively as opposed to reactively, try testing in production! You will have an increased accuracy of test results, your tests will run faster due to the elimination of bad data, and you will have higher confidence before releases. This can be accomplished through feature flagging, canary releases, setting up a proper CI/CD pipeline, and data cleanup. You will leave this talk with strategies to mitigate risk, to better your understanding of the steps to get there, and to shift your company’s testing culture, so you can provide the best possible experience to your users. At the end of the day, we don't care if your features work in staging, we care if they work in production. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Node.js core no tiene una hoja de ruta oficial: es la suma de los intereses y esfuerzos de los colaboradores lo que determina la dirección futura del proyecto. La evolución de una nueva característica en Node.js puede tomar diferentes giros y vueltas. Algunas características nuevas se implementan como experimentales, para dar tiempo a recopilar comentarios de los usuarios antes de considerarlas estables. Otras características se implementarán como estables desde el principio. Entonces, ¿qué hay en el horizonte? Esta charla echará un vistazo a algunas de las características nuevas y experimentales en el núcleo de Node.js. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Node.js: lo Nuevo y lo Experimental

Beth Brix, a senior software engineer at Red Hat, discusses new and experimental features in Node.js, the release process, API stability, and the importance of user feedback. Some stable features in Node.js 15 include the abort controller, MPM7, and V886. Node 14 is the most popular version among users. The future releases of Node.js will likely include a major v8 update with new JavaScript language features. The Node community is supportive and willing to help users with migration and finding solutions.

Node.js core does not have an official roadmap - it’s the sum of the interests and efforts of the contributors that determines the future direction of the project. The evolution of a new feature in Node.js can take different twists and turns. Some new features land as experimental, to give time to gather user feedback before they’re considered stable. Other features will land as stable from the start. So, what’s in the pipeline? This talk will take a look at some of the new and experimental features in Node.js core. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Infrastructure as Code with a Node Focus

Tejas Kumar

Cuando se solucionan problemas en aplicaciones complejas de Node.js, siempre es útil recopilar información sobre la red, el sistema de archivos o las dependencias externas. Incluso al trabajar con una nueva base de código, es importante tener información sobre cómo se construye la aplicación, qué llamadas asíncronas se están utilizando y con qué frecuencia. En esta charla, quiero presentar "instrument", una herramienta que he creado para esto y que también es de código abierto.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Instrumentando Internals de Node.js

The Talk is about troubleshooting Node.js applications and using a tool for improved visibility and information. The tool can collect information about URLs and module imports in a server. However, it is not recommended for use in non-local environments due to performance overhead and potential bugs.

When troubleshooting complex Node.js applications recollecting information about the network, filesystem or external dependencies is always useful. Even when working with a new codebase insights on how the application is built, which asynchronous calls are being used or how often. In this talk I want to introduce "instrument", a tool I've created for this which is also Open Source. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Cómo solucionar errores de API y reducir MTTD/R

Today's workshop focused on observability in modern Node.js applications and the challenges in distributed systems. The workshop covered building an Express application, making API requests, deploying to AWS Lambda, and integrating with Epsilon for tracing and troubleshooting. Epsilon provides a comprehensive solution for monitoring and troubleshooting, including visualizing trace data, indexing requests, and creating alerts. The workshop also included a treasure hunt contest to find a hidden password within the APIs. Overall, the workshop emphasized the importance of observability and provided practical tools and techniques for implementing it in real-world applications.

The benefits of Node.js to develop real-time applications at scale are very well known. As Node.js architectures get more and more complex, visualization of your microservices-based architecture is crucial. However, the visualization of microservices is incredibly complex given the scale and the transactions across them. In this workshop, you will learn how to leverage service maps to instantly understand your architecture and troubleshoot any API error. We will write a simple Express application and explore best practices when using Express. Then, we’ll deploy the application on AWS, integrate the environment with Epsagon, and deep-dive into various features of the platform to enable immediate detection and fast troubleshooting of application errors. Goals: Visualizing your architecture, monitoring your applications, reducing your mean time to detection and recovery (MTTD and MTTR). Who should attend? DevOps, Engineers, Cloud Architects, IT, Software Developers, Solution Architects and Engineers, SREs, and anyone who is running microservice-based applications (Kubernetes, containers, serverless functions, and more) in the cloud.

En esta charla, nos divertiremos intentando manipular un proceso de Node.js en ejecución para cambiar su comportamiento en tiempo de ejecución. Sin cambiar el código ni reiniciar el proceso, encontraremos una forma de inyectar nuestra propia lógica en él y comenzar a hacer las cosas que queremos. ¿Cuáles son las limitaciones de este enfoque? ¿Hay alguna parte de él que se pueda utilizar en escenarios de la vida real? ¡Ven y descúbrelo! Sí, habrá una demostración en vivo.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

¿Puedes Cambiar el Comportamiento de un Proceso de Node.js en Ejecución desde el Exterior?

This talk explores how to remotely change the behavior of a Node.js process at runtime and inject a logger using the Chrome DevTool protocol. It demonstrates the power of dev tools and encourages their usage. Remote debugging is useful for debugging memory leaks in production. The method requires local machine access and has security implications, but it requires significant access and indicates a major breach. The talk emphasizes the importance of having awareness and monitoring in place for application protection.

In this talk, we will have fun trying to tamper with a running Node.js process to change its behavior at runtime. Without changing the code or restarting the process, we will find a way to inject our own logic into it and start to do the things we want. What are the limitations of such an approach? Is there part of it that can be used in real life scenarios? Come and find out! Yes, there will be some live demo. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Durante años, AWS ha ofrecido CloudFormation como un enfoque para la Infraestructura como Código (IaC). CloudFormation permite la provisión de pilas de aplicaciones a partir de plantillas en formato JSON o YAML. Desafortunadamente, debido a su tamaño y complejidad, las plantillas de CloudFormation han ganado una reputación de ser difíciles de manejar. El AWS Cloud Development Kit (CDK) mitiga parte de la complejidad asociada con CloudFormation, permitiendo a los desarrolladores definir programáticamente su arquitectura en la nube utilizando lenguajes de alto nivel familiares como JavaScript y TypeScript. Los proyectos de CDK luego pueden ser implementados a través de CloudFormation, manteniendo todos los beneficios de CloudFormation, como implementaciones repetibles y detección de desviaciones. Esta charla presentará el CDK en el contexto de Node.js y demostrará cómo se puede aprovechar para la provisión de arquitecturas nativas en la nube. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Introducción al AWS CDK: Infraestructura como Código

The AWS CDK is an infrastructure as code tool that supports multiple programming languages and helps mitigate concerns about vendor lock-in. It uses JSII to support different languages and allows you to write code once and get the same API across different languages. The CDK simplifies resource creation and management in AWS, addressing the verbosity and error-proneness of CloudFormation. CDK applications consist of apps and stacks, with stacks mapping to CloudFormation stacks. The CDK provides a more compact and familiar syntax compared to CloudFormation, making it easier for JavaScript developers to handle the entire stack.

For years AWS has offered CloudFormation as an approach to Infrastructure as Code (IaC). CloudFormation allows application stacks to be provisioned from JSON or YAML formatted templates. Unfortunately, due to their size and complexity, CloudFormation templates have earned a reputation as being unwieldy to work with. The AWS Cloud Development Kid (CDK) mitigates some of the complexity associated with CloudFormation allowing developers to programmatically define their cloud architecture using familiar high-level languages such as JavaScript and TypeScript. CDK projects can then be deployed via CloudFormation, while retaining all of the benefits of CloudFormation, such as repeatable deployments and drift detection. This talk will introduce the CDK in the context of Node.js and demonstrate how it can be leveraged to provision cloud native architectures. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Los beneficios de Node.js para desarrollar aplicaciones en tiempo real a gran escala son muy conocidos. A medida que las arquitecturas de Node.js se vuelven más complejas, la visualización de su arquitectura basada en microservicios es crucial. Sin embargo, la visualización de los microservicios es increíblemente compleja dada la escala y las transacciones entre ellos. No solo necesitas visualizar tus aplicaciones de Node.js, sino también analizar la salud, el flujo y el rendimiento de las aplicaciones para tener una solución de observabilidad completa. En esta charla, repasaremos los desafíos de escalar tus aplicaciones de Node.js y las herramientas (como el rastreo distribuido) disponibles para escalar con confianza. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Observabilidad Integral a través del Rastreo Distribuido en Node.js

Welcome to the session on comprehensive observability via distributed tracing on Node.js. We'll explore the challenges of microservices and troubleshoot distributed applications using an example. Correlation is the missing piece in troubleshooting distributed applications. Distributed tracing helps pinpoint issues that logging or metrics may miss, reducing mean time to resolution. It provides visualization of microservices architecture, actionable data, and enables code optimization.

The benefits of Node.js to develop real-time applications at scale are very well known. As Node.js architectures get more and more complex, visualization of your microservice-based architecture is crucial. However, the visualization of microservices is incredibly complex given the scale and the transactions across them. You not only need to visualize your Node.js applications but also analyze the health, flow, and performance of applications to have a complete observability solution. In this talk, we'll go over the challenges of scaling your Node.js applications and tools (such as distributed tracing) available to you to scale with confidence. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
