Yes, Your Browser Can Do That (Probably) — A Look At Modern Web APIs You Might Not Know
We’ve become so accustomed to aiming to develop native apps to get access to certain advanced features and functionality that it’s easy to miss that a lot of these have been adopted slowly but surely by our web browsers over time. In this talk, we’ll have a look at some of these Web APIs, how they work, and how you can use them to progressively enhance the experience of your users in a real-life context.

Total ReDoS: The Dangers of regex in JavaScript
Regular expressions are complicated and can be hard to learn. On top of that, they can also be a security risk; writing the wrong pattern can open your application up to denial-of-service attacks. One token out of place, and you invite in the dreaded ReDoS. In this talk, we’ll track down the patterns that can cause this trouble, explain why they are an issue, and propose ways to fix them now and avoid them in the future. Together we’ll demystify these powerful search patterns and keep your application safe from expressions that are anything but regular.

Lets Build A Node.js ChatGPT-Like Bot With AI APIs
AI is currently one of the hottest trends. Everyone talks about generative AI and thinking about how to add AI capabilities and use LLMs to extend the business capabilities of their servers. In this talk, Tamar will build a “Question-Answer” bot that resembles ChatGPT with AI tools. After a quick crash course in the AI land, in which we will understand several terms like LLM, Generative AI, and RAG (Retrieval Augmented Generation), Tamar will build an AI application. The application will be using a pre-defined dataset and will be able to provide the functionality of accurate answers – even if the question is not very precise. At the end of this talk, you will understand AI better and can start combining AI APIs in your application.

Stop using JS for that: Moving features to CSS and HTML.
If you’ve been building websites for a while, you “know” that some things require JS, and that’s just the way it is. It turns out that spec writers and browser makers are both working hard to find common JS patterns and implement them in CSS and HTML. Things like accordions, auto-suggest, smooth scrolling, and dialogs are all available without JS. Looking a little ahead, things like parallax scrolling, styleable selects, and component-dependent styling are expected to make their CSS debut as well.

Welcome, Fastify v5
With the release of Fastify v5, exciting new features and significant changes have arrived, but so have breaking changes that require careful migration. In this talk, we will guide you through the process of upgrading from Fastify v4 to v5, starting with fixing deprecated v4 warnings, updating your Node.js version to v20+, and adapting to breaking changes like the full JSON schema requirement, new logger signature, and removal of variadic arguments in .listen(). We’ll also cover important updates such as enhanced security measures, streamlined request and reply behavior, and the removal of non-standard HTTP methods. Additionally, we’ll explore new features like native Diagnostic Channel support for tracing request lifecycles. Whether you’re planning to upgrade soon or need time with v4’s LTS, this session will prepare you for a smooth transition to Fastify v5.

Escape Room
XtremeJS Escape Room
The Escape Room game takes place online. The participants in this game will need to find their way out by overcoming a digital lock. The first that succeeds to overcome the digital lock wins the game. In order to overcome the digital lock the participants will need to code various small programs in JavaScript.

Losing your Components’ Head
Every web project will eventually need a components library no matter which framework you are using. But, the requirements in each project are different, and even if you find a component library, it will have its own opinionated UI look and feel or rendering. This is where headless components can help you achieve your project’s goals. Join me to understand what are headless components and why you should consider using this pattern in your projects.

End to End Testing for Browser Extensions
We will discuss the fundamentals of browser extensions (Chromium browsers and Firefox), explore the current options available for end-to-end testing, and dive into some live coding to see it in action. By the end of this presentation, you’ll have the knowledge and skills to implement end-to-end testing for your own browser extension.

Mastering JavaScript Collections: Arrays, Maps, Sets, and Beyond
In this session, we will dive deep into the core collection types in JavaScript—arrays, maps, and sets—unpacking their unique characteristics and use cases. You’ll learn how to leverage these structures efficiently, explore advanced techniques, and understand when to use each type for optimal performance. We’ll also go beyond the basics and introduce the WeakMap collection. Whether you’re a beginner or a seasoned developer, this talk will provide valuable insights into handling data structures in modern JavaScript.

Independent Popups with Element Reparenting & The HTML Popover API
With increasing adoption of modern CSS techniques like layout containment and transformed elements, CSS-only solutions for popups are increasingly beholden to the elements containing them. Learn about the concepts in the W3 standard that can cause layout issues when combining CSS-only popovers with modern rendering techniques, and how to use the recently-released HTML Popover API to create popups that are truly independent of their location in the DOM. In addition, learn how DOM-independent popovers can still be created without the Popover API using element reparenting.

HTMX – Say “no” to Complexity
This talk describes building web applications focused on hypermedia, an approach that differs significantly from the SPA frameworks popular today such as React and Angular. Today, web apps typically use client-side JavaScript code to send HTTP requests to server endpoints that query/update databases and return JSON data. The client code then transforms JSON into an HTML presentation. This is not what Roy Fielding had in mind when he wrote his famous dissertation “Architectural Styles and the Design of Network-based Software Architectures” that gave birth to REST. HTMX is a small, client-side JavaScript library that adds support for new HTML attributes. These enable responding to specific interactions (e.g. click) with any HTML element by sending an HTTP request using any verb. The response must contain HTML. Rather than performing a complete page refresh, the returned HTML replaces an existing DOM element or is inserted relative to one. The server can be implemented using any programming language and server framework. While htmx itself is implemented in JavaScript, htmx enables writing complete web applications without authoring any JavaScript code..
