Hacia una Biblioteca Estándar para Runtimes de JavaScript

There is a need for a standard library of APIs for JavaScript runtimes, as there are currently multiple ways to perform fundamental tasks like base64 encoding. JavaScript runtimes have historically lacked a standard library, causing friction and difficulty for developers. The idea of a small core has both benefits and drawbacks, with some runtimes abusing it to limit innovation. There is a misalignment between Node and web browsers in terms of functionality and API standards. The proposal is to involve browser developers in conversations about API standardization and to create a common standard library for JavaScript runtimes.

En esta charla, obtendremos una demostración en vivo de la construcción de autenticación personalizada. Cuando tienes las herramientas adecuadas (y nosotros las tenemos), la autenticación puede ser bastante simple y segura. Esto es más (y mejor) que simplemente: "Instala esta biblioteca y estás listo para ir". Cuando terminemos, tendremos nuestro propio código de autenticación que puede evolucionar con nuestros requisitos en constante cambio sin necesidad de aprender algunas APIs específicas de la biblioteca. Estaremos aprovechando la Plataforma Web de la manera en que se suponía que debía hacerse para darnos una autenticación del lado del servidor simple y segura para la web.

Autenticación del lado del servidor con Remix, Prisma y la Plataforma Web

This Talk is about server-side authentication with Remix, Prisma, and the web platform. It covers adding authentication to a Remix app, troubleshooting and login setup, handling user login and session creation, creating user sessions and redirects, handling user ID retrieval and validation, and working with cookies in Remix. The speaker emphasizes that Remix is ready for production and suitable for enterprise apps. Remix simplifies the mental model and improves performance by bridging the network gap between the front end and back end.

In this talk, we'll get a live coded demo of building custom hand-rolled authentication. When you have the right tools (and we do), authentication can be quite simple and secure. This is more (and better) than just: "Install this library and you're good to go." When we're done we'll have our own auth code that can evolve with our ever-changing requirements without a need to learn some library-specific APIs. We'll be leveraging the Web Platform the way it was meant to be done to give us simple and secure server-side authentication for the web.

Estaba viendo código que fue escrito hace unos años, que se consideraba "súper limpio" e "intuitivo", y me di cuenta de que el JavaScript que escribimos hoy es muy diferente al que solíamos escribir hace solo cinco años. Si has estado en esto por un tiempo, conoces la sensación de escribir "this = that" y pasar días depurando por qué esa variable se establece en null. La nueva sintaxis de Node, con esm, nuevos bundlers, refrescos más rápidos. El código nunca fue tan fácil de escribir y entender. Puedes revisar las diapositivas de la charla de Pedro <a href="https://node-like-its-2022.vercel.app/">aquí</a>. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Escribe Node como si estuviéramos en 2022

Let's write Node like it's 2022. We can now iterate over objects more easily with the for-in loop. Template literals make string concatenation and multi-line strings much simpler. The structured clone feature allows us to clone complex objects without the need for hacks like stringifying and parsing. Default parameters in JavaScript are now much more convenient. Async await eliminates the need for callbacks. Arrow functions inherit the scope, eliminating the need for 'this equals that'. Const prevents variable reassignment. Let helps catch errors earlier. Write code like it's 2022!

I was seeing some code that was written a few years ago, that was considered the "super clean" and "intuitive", and I realised that the JavaScript that we write today is very different from the one that we used to write just five years ago. If you've been around for some time, you know the feeling of writing "this = that", and taking days debugging why that variable is set to null. The new node syntax, with esm, new bundlers, faster refreshes. The code was never so easy to write and understand.

En la era posterior a la Ley de Moore, debido a las limitaciones del hardware, necesitamos exprimir más rendimiento del hardware existente. Eso significa que el código nativo proporciona el mejor rendimiento. Sin embargo, la prevalencia del código nativo en el lado del servidor presenta desafíos para la seguridad y la administración de aplicaciones. El surgimiento y la llegada de Rust y WebAssembly ofrecen nuevas formas para que los desarrolladores escriban aplicaciones Node.js de alto rendimiento pero seguras. En esta charla, cubriré los conceptos básicos de Rust y WebAssembly, así como también mostraré cómo integrarlos con Node.js. Aprenderás cómo y cuándo diseñar una aplicación web híbrida. Cómo puedes codificar las funciones de alto rendimiento en Rust en una máquina virtual de WebAssembly y finalmente cómo unir todo en una aplicación JavaScript de Node.js.<a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Node.js de Alto Rendimiento Potenciado por Rust y WebAssembly

This talk explores using Rust and WebAssembly to enhance the performance of Node.js applications. By leveraging Rust's efficiency and safety features, and compiling it into WebAssembly bytecode, developers can achieve high-performance computations while ensuring security. WebAssembly enables direct communication with native hardware and is optimized for server-side applications, making it suitable for tasks like AI inference and storage databases. Overall, this talk highlights the potential of combining JavaScript, Rust, and WebAssembly to build performant and portable applications.

In the post Moore’s Law era, due to limitations of the hardware, we need to squeeze more performance from the existing hardware. That means that the native code provides the best performance. However, the prevalence of native code on the server-side presents challenges to application safety and manageability. The rise and advent of Rust and WebAssembly offers new ways for developers to write high performance yet safe Node.js applications. In this talk, I will cover the basics of Rust and WebAssembly, as well showcase how to go about their integration with Node.js. You will learn how and when to design a hybrid web application. How can you code the high performance functions in Rust in a Web Assembly virtual machine and finally how to tie everything together in a Node.js JavaScript application. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

“Nunca creerás de dónde vienen los objetos en JavaScript.” “Estos 10 lenguajes son peores que JavaScript en programación asíncrona.” Exploraremos algunos aspectos de JavaScript que podrías dar por sentado en el taller más sensacionalista de nodecongress.com. Para asistir a este taller solo necesitas ser capaz de escribir y ejecutar código NodeJS en tu computadora. Tanto desarrolladores junior como senior son bienvenidos. Los objetos son de Marte, las funciones son de Venus Sumergámonos en los entresijos de los objetos y luego ampliemos nuestra perspectiva para ver los módulos desde un punto de vista diferente. ¿Cuántas formas hay de crear objetos? ¿Son realmente útiles? ¿Cuándo deberías considerar usarlos? Si ahora estás pensando `¿a quién le importa?`, entonces este taller es probablemente para ti. JavaScript asíncrono: ¿las partes buenas? Tengamos una conversación honesta. Quiero decir... ¿por qué, oh por qué, tenemos que lidiar con todo esto? Supongo que también depende de la perspectiva. Primero asumamos una verdad incómoda al respecto: podría ser peor... luego tal vez podamos empezar a ver las características no tan malas, incluso geniales, de JavaScript en relación a los programas no bloqueantes. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Vuelta a los fundamentos

This workshop covers basic principles and patterns in software development and engineering. It explores topics such as objects, functions, prototype chains, classes, modules, and asynchronous programming in JavaScript. The workshop emphasizes the importance of understanding context, encapsulation, and the use of promises for managing asynchronous behavior. It also discusses the differences between synchronous and asynchronous code execution and provides insights into the design patterns and best practices for writing efficient and maintainable code.

“You’ll never believe where objects come from in JavaScript.” “These 10 languages are worse than JavaScript in asynchronous programming.” Let’s explore some aspects of JavaScript that you might take for granted in the clickbaitest nodecongress.com workshop. To attend this workshop you only need to be able to write and run NodeJS code on your computer. Both junior and senior developers are welcome. Objects are from Mars, functions are from Venus Let’s deep-dive into the ins and outs of objects and then zoom out to see modules from a different perspective. How many ways are there to create objects? Are they all that useful? When should you consider using them? If you’re now thinking “who cares?“, then this workshop is probably for you. Asynchronous JavaScript: the good? parts Let’s have an honest conversation. I mean… why, oh why, do we need to bear with all this BS? My guess is that it depends on perspective too. Let’s first assume a hard truth about it: it could be worse… then maybe we can start seeing the not-so-bad-even-great features of JavaScript regarding non-blocking programs. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Blitz fue creado como un framework full-stack de React, inspirado en Ru on Rails, y con el objetivo de hacerte lo más productivo posible. Cuenta con una capa de abstracción de datos "Zero-API", autenticación y autorización integradas, y algunas características más emocionantes. Sin embargo, recientemente decidimos cambiar Blitz a un kit de herramientas independiente del framework, lo que significa un cambio enorme y emocionante para la comunidad de Blitz. Durante esta charla, presentaré los conceptos principales, hablaré sobre el por qué y el cómo del cambio, y te daré un vistazo al futuro de Blitz.

Un vistazo al futuro del desarrollo full-stack con Blitz.js

Today's Talk focused on the future of full-stack web development with Blitz.js. Blitz is a React framework built on top of Next.js, offering direct database access and authentication with authorization. The core features of Blitz include the zero-API layer and the ability to run server code directly from the frontend. The future of Blitz includes expanding to other frameworks and runtime environments. The new Blitz toolkit will be decoupled from any specific framework, allowing developers to choose their preferred foundation. It will retain the core value of Blitz while adding additional features like JWT authentication and advanced data-aware authorization. The migration to the new toolkit will be seamless for existing Blitz projects. The Blitz toolkit will have a plugin system for customization and support multiple resolvers. The Blitz project is currently going through a pivot and will focus on the Blitz toolkit. The goal is to release the toolkit by the end of March. The most exciting part of the toolkit is the plugin system design that allows users to customize their experience.

Blitz was created as a fullstack React framework, inspired Ru on Rails, and with a goal to make you as productive as possible! It features a ""Zero-API"" data layer abstraction, has authn &amp; authz out of the box and a few more exciting features. However, we recently decided to pivot Blitz to a framework agnostic toolkit, which means a huge and thrilling change for the Blitz community. During this talk, I will introduce the core concepts, talk about the why &amp; how of the pivot, and give you a glimpse of Blitz's future.
