Aaron Joel Fernandes How to Deploy a Node.js Application using Docker and Kubernetes.
In today’s cloud-native era, writing great code is only half the story—deploying it efficiently and reliably is just as critical. In this session, you’ll follow the end-to-end journey of a simple Node.js application, from local development to a fully containerized environment and orchestrated deployment with Docker and Kubernetes. Along the way, you’ll gain practical insights into building, packaging, and running applications at scale in modern infrastructure.

Boy Scout Rule in the Age of AI: Leaving Codebase Cleaner than You Found it
Artificial Intelligence is rapidly becoming embedded in developers’ workflows (from code-generation assistants to auto-refactoring bots) — and often the temptation is to rely on it blindly, which can lead to messy and brittle code with a lot of duplication. This talk explores how the “always leave the code cleaner than you found it” rule can be applied to modern code bases powered by AI. We will talk about concrete techniques like setting up and enforcing codebase standards, providing exhaustive context, linting, formatting, unit- and e2e-testing, refactoring code incrementally, and keeping docs up to date. By the end, you will have a toolkit of strategies to make sure your AI-assisted code is not only working — but also remains maintainable and readable.

Scaling Micro-Frontend Architecture with React Module Federation
This talk presents a real-world case study of moving a large web application to a micro-frontend architecture using React and Webpack Module Federation. The speaker will dive into how to break down monolithic frontend applications into independent, reusable modules. Key topics include optimizing performance, managing dependencies across micro-frontends, and setting up CI/CD pipelines to ensure smooth deployments. The session will also cover the integration of tools such as React-Query, Next.js’s server-side rendering, and performance improvements for large-scale applications.

XtremeJS Hackathon
XtremeJS Hackathon
An intense, fast-paced competition where participants race to solve a real-world programming challenge. Any tool, any library – even AI – is allowed. The first to build a working solution, submit the code, and deliver the correct result claims victory. A thrilling test of speed, creativity, and coding mastery.

What React Looks Like When Code Writes Itself
AI has reached the point where it is not just helping us write React code, but is fundamentally reshaping how we architect applications. This talk examines the patterns, anti-patterns, and surprising architectural decisions that emerge when React applications are built primarily through AI-assisted code. Through analysis of dozens of AI-generated React projects, we’ll explore how LLMs approach component design differently than human developers, favoring composition over inheritance, creating unexpectedly flat component hierarchies, and generating test suites that reveal blind spots in traditional testing approaches. Through a live demo, we’ll explore an LLM-scaffolded React app, examining its folder structure, component design, and testing patterns, and compare it to human-written code. We’ll discuss unique trends, like LLM tendencies to favor functional components with TypeScript or to nest contexts excessively, and their implications for maintainability and performance. Attendees will leave with insights into leveraging LLMs effectively, recognizing AI-generated code smells, and adapting these patterns for scalable, production-ready React apps.

This DoS goes loop-di-loop – preventing DoS attacks in your Node.js application
Node.js’ single-threaded nature makes it very susceptible to DoS attacks. While Node.js’ event loop allows performing some operations in an asynchronous fashion, it’s still quite easy to write a vulnerable Node.js application by making a few simple mistakes. In this talk I’ll cover some common ways a Node.js application may be vulnerable to DoS attacks and some common best-practices and counter measures to defend against such attacks.

Creating Tree Shakeable NPM packages
NPM packages are the most popular and powerful way today for making your code reusable and share it between various projects. But as most of us are starting to code for the web by developing web applications, when the time comes and we need to create and publish our own first NPM package, we find ourselves guessing what the best practices are we should follow.

Lazy Powers: Iterator Helpers in ECMAScript 2025
Iterators have always been a quiet powerhouse in JavaScript, enabling developers to work with sequences of data in flexible and efficient ways. With ECMAScript 2025, iterators take a major leap forward through the introduction of Iterator Helpers—a set of built-in methods like map, filter, take, and drop that bring functional programming patterns directly to iterators. In this session, Haim Michael will explore how these helpers unlock the true lazy powers of JavaScript. You’ll learn how to build expressive data pipelines without the overhead of manual loops, process large collections efficiently through lazy evaluation, and write code that is cleaner, more modular, and easier to maintain. We’ll walk through practical examples, explore real-world use cases, and highlight how Iterator Helpers can optimize performance in distributed and data-heavy applications. Whether you’re building front-end features, server-side applications, or handling streams of data, these new tools will change the way you think about iteration. By the end of the talk, you’ll see why Iterator Helpers are one of the most exciting additions to JavaScript in years—and how to start using them to supercharge your development.

30 Tips for Secure JavaScript
In this talk, we will cover 30 tips for writing more secure JavaScript, emphasizing what to do, what NOT to do, and utilizing open-source tooling to enhance security. JavaScript is not only the most popular web programming language, but it also faces security threats like XSS and code injection, meaning we need to ensure our JavaScript is tough, rugged, and secure. We’ll touch only upon items that are specific to JavaScript, as opposed to agnostic topics that apply to all languages, such as encryption or authentication. By the end, you’ll gain insights into selecting the best framework, adopting secure coding practices, and leveraging tools for web application security, catering to both seasoned developers and beginners seeking practical guidance.

HTTP Message Signatures Demystified: Stronger Security for JavaScript
APIs power modern software, yet many still depend on weak security methods like API keys or bearer tokens. While simple, these approaches offer minimal real protection. Mutual TLS (mTLS) is far more secure but remains notoriously difficult to implement across public APIs and diverse client environments. What developers truly need is a security solution that is flexible, transparent, and resilient—strong enough to safeguard today’s distributed systems without adding unnecessary complexity.
