As AI coding assistants like Cursor, Jules, Cline and Copilot revolutionize software development, a new reality emerges: while these tools excel at generating boilerplate and routine functions-roughly 70% of coding work-they struggle with the crucial final 30% that transforms a basic solution into production-ready software. This talk explores how developers can adapt to this paradigm shift by strategically embracing AI for what it does best while doubling down on uniquely human skills. Drawing from industry leaders' insights, we'll examine why AI struggles with essential complexity like system architecture, edge cases, and maintainability, and how developers can position themselves as indispensable collaborators rather than competitors with AI. Whether you're a senior architect seeking to amplify your impact or a junior developer navigating this rapidly evolving landscape, you'll leave with practical strategies to elevate your craft beyond what AI can generate. Learn how to transform from code writers to systems thinkers, becoming "power users" who leverage AI as a force multiplier while maintaining ownership of the engineering decisions that matter most.

Signals and fine-grained reactivity have recently become staples in modern JavaScript frameworks. However, 9 years ago, when Ryan Carniato created SolidJS, the blueprint for the modern framework, that was not the case at all. Today more developers use Signals than ever before, but we are only at the beginning of the journey. Join Ryan as he looks to the future of fine-grained reactivity, web development, and explores what lies beyond Signals.

JavaScript represents a big part of page weight - and optimising for performance often requires trimming or optimising the bundle - albeit imperfectly. At the same time, bundlers have never been more important in full-stack JS frameworks. In this session we’ll be rethinking how bundlers can optimise JS, if we let go of some of our previous assumptions about what bundling means.

Rethinking Bundling: Why You Don’t Need Less JavaScript

Daniel Roe

Developers have gone full-steam from traditional programming to AI code assistants and vibe coding but where does that leave application security? What are the risks of LLMs introducing insecure code and AI applications manipulated through prompt engineering to bypass security controls?In a series of real-world application hacking demos I’ll demonstrate how developers mistakenly trust LLMs in generative AI code assistants that introduce insecure code and result in vulnerable applications that attackers easily exploit against you. We don’t stop here. We’ll apply adversarial attacks on neural networks in the form of prompt injection payloads to compromise LLMs integrated into AI application workflows and weaponize them for SQL injection and other business logic bypass.Join me in this session where you’ll learn how security vulnerabilities such as path traversal, prototype pollution, sql injection and other AI security risks are impacting LLMs and how to leverage AI security guardrails to secure GenAI code.

Frontend frameworks are increasingly converging, not just in features like Signals or first class TypeScript support, but also in shared tooling. Vite now powers most ecosystems, and meta-frameworks increasingly rely on Nitro and other unified layers.In this talk, we’ll look at the next phase of this convergence: the rise of Rust-powered tooling that will improve our workflows. Up first is Rolldown, a next-gen bundler offering not only speed or compatibility with Rollup, but also advanced optimization features like granular chunk control. Another tool, actually a set of tools that is part of the equation is Oxc, the Oxidation Compiler, a modular toolchain for parsing, transforming, minifying, but also linting and formatting JavaScript - at scale.You’ll leave with a clearer picture of where frontend tooling is heading and how you can adopt these tools today to benefit of the out-of-the-box performance and advanced features.

Imagine the convenience of executing TypeScript files directly with Node.js using `node file.ts`. Just a few years ago, this concept seemed like a distant dream. Today, it stands as an exciting experimental feature. This narrative dives into the journey of transforming this dream into a reality. Integrating TypeScript natively into Node.js posed significant challenges. These hurdles included managing TypeScript’s lack of strict semantic versioning guarantees and accommodating various TS flavors. Today, the experimental native TypeScript support in Node.js marks a transformative milestone. Beyond merely executing .ts files, it signifies a leap forward in JavaScript development.

Have we been stuck in the same testing pain loops for years? Even though it might seem like it, we haven't!Even if AI is now writing our tests, many JavaScript developers have faced numerous challenges, from the unclarity of test classifications to the struggle of mocking, long-running integration tests, and shifting everything to E2E tests.Let's recap everything that has happened in the past years and look into the present to explore what 2025 will bring for testing in the JavaScript world around test runners, testing libraries, mocking, production practices, and AI-based tools.

The 2025 State of JavaScript Testing

Daniel Afonso

Compilers have long been seen as one of the most complex topics in computer science. Nowadays, web frameworks are evolving from runtime libraries into optimizing compilers and reshaping how we build user interfaces. Different topics in front-end development—e.g., reactive programming—are now experiencing this era fueled by static-analysis-driven insights.This talk will explore how modern UI compilers are redefining performance and developer experience. We’ll discuss how some compilers are designed and different open-source solutions — including the React Compiler, Million.js, Svelte, and Marko, as well as enterprise apps, and the growing role of compilers in automating things.By the end of the session, you'll probably be optimistic about a future where compilers understand our entire code and offload a huge part of our mental burden related to manual tasks!

Compilers, User Interfaces & the Rest of Us

We all have those repetitive web tasks we wish would just handle themselves – sorting through data, extracting information from multiple pages, or customizing content for different audiences. What if your JavaScript application could do this autonomously, right in the browser?This talk demonstrates how to create intelligent AI agents in JavaScript that eliminate tedious tasks without sending sensitive data to the cloud. We'll combine modern web technologies with client-side AI techniques like RAG (Retrieval-Augmented Generation) and function calling to build applications that understand content, make decisions, and take actions based on user goals.

Let's Build Your Personal AI Agent in JavaScript

Join me for a technical deep-dive on TypeGPU which, among other things, allows your WebGPU shader to be made up of JavaScript either partially or entirely. This means a library can be written fully in WebGPU Shading Language, yet accept a JS callback that gets compiled and injected into the shader code. Improving APIs by going past just tweaking knobs and parameters.In my talk, I’ll be touching upon how we offload most of this work to a build-step while still supporting dynamic scenarios, how we mitigate the differences between JavaScript and WebGPU Shading Language, and how we leverage existing tooling like the TypeScript language server to make CPU and GPU code connect seamlessly through types.

Great teams don’t wait for a single “smart” tool to do everything – they wire simple pieces together. In this talk, I’ll show how combining multiple MCP servers lets an AI agent carry the right context from design to code without ceremony. We’ll pair Figma’s Dev Mode MCP server – which exposes structured design signals like variables, components, and Code Connect mappings – with a tiny custom server I wrote that bridges two repos: one for the design system and one for the app. You’ll see how each server contributes different context (design semantics here, repo search/write actions there), and how the agent stitches them into real changes: opening PRs, updating tokens, and keeping UI and code in sync. Along the way I’ll share the patterns, guardrails, and a minimal template you can adapt to your stack – no vendor pitch, just practical composition you can ship tomorrow.

The web platform is evolving, introducing powerful new primitives that change how we build interfaces. Among these innovations is the toplayer – an important yet often misunderstood rendering concept. This talk explores the toplayer rendering mechanism, learning how it enables UI patterns and examining its role in accessibility, performance, and developer experience.The toplayer isn't just another technical specification—it represents a shift in how browsers handle elements that need to break out of the normal document flow. From dialog elements to the new popover API, custom tooltips to modal interfaces, the toplayer has quietly become essential for creating modern web experiences. By understanding how the toplayer works, developers can build more robust, accessible, and maintainable components while avoiding common pitfalls that lead to inconsistent user experiences.In this session, we'll dive into the toplayer to understand how browsers handle stacking contexts, painting order, and focus management within the toplayer. Through practical examples and live coding demonstrations, attendees will gain both theoretical understanding and practical skills they can apply to their own projects.

Give an AI access to a real Node.js runtime, and things start to get interesting. It can run code, install packages, generate files, and even launch servers on the fly. In this talk, you will see how I built a Node.js Sandbox server powered by the Model Context Protocol (MCP), an open standard that connects AI to real tools and data in a safe, controlled way.We will walk through how the sandbox works: starting fresh Docker containers, installing npm packages on the fly, executing JavaScript, and sending back logs or files. Everything happens through simple MCP messages, allowing the AI to interact with your system just like a developer would, only faster.You will see how this unlocks powerful use cases like generating charts with Chart.js, summarizing long articles from the web, creating and testing QR codes, scraping and saving content, generating PDFs and fake CSV data, or even spinning up mock APIs in seconds. By the end, you will know how to build your own MCP server and give your AI the keys to a real coding playground.

Behind every healthcare dashboard or billing report is a complex web of data logic, regulatory standards, and human decisions. As a Senior Analyst working at the intersection of medical finance and technology, I’ve spent years navigating payment audits, EHR systems like EPIC, and revenue optimization — all using SQL, Python, and data visualization platforms like Tableau.But too often, the tools we rely on break down at the interface level. Whether it’s a dashboard that hides critical edge cases, a confusing filter logic, or performance bottlenecks with large datasets, the gap between engineers and analysts becomes painfully clear.In this talk, I’ll share what non-JavaScript professionals (like data analysts and healthcare teams) wish JS developers understood — from the importance of transparent data flows and smart defaults, to accessibility for non-technical users and the challenges of real-world billing logic.This isn’t a technical deep dive into code — it’s a real-world case study of how design decisions in JS-powered tools can make or break healthcare outcomes, and how engineers can build better, more empathetic data tools.

For years, we’ve defaulted to centralised servers and, more recently, leaned heavily on server-side components to power our web apps. But this dependence has a cost: apps that break without constant internet connectivity, sluggish performance under heavy load, and user frustration when things don’t just work. This talk challenges the cloud-first status quo and invites developers to explore the power of **local-first**. Imagine building multiplayer, collaborative experiences that thrive offline, sync smoothly when online, and harness the value of localised state. We’ll also tackle the complexities of conflict resolution when shifting from a centralised authority to a sync server as a lightweight mediator. It’s time to rethink collaboration.

Today it's possible to create advanced eye tracking systems without specialized hardware but simply using a standard webcam and the inevitable AI. But the real difference is made by the model that is already completely on the edge and therefore on the device or browser, allowing you to work even offline! With 'AI on the edge' technologies for facial and eye detection, a bit of linear regression, and a real-time calibration system that adapts to the user and environment, I will show, using only JavaScript and on-device AI models,  the results of the experiment, discussing accuracy, current limitations, and potential improvements. The challenges faced in on-device optimization are many to balance precision and performance, but this experiment opens new possibilities for accessible applications in human-machine interaction, behavioral studies, and accessibility systems, all created with open source technologies and common hardware!

npm powers the JavaScript ecosystem, but many developers still treat it as a black box.This talk aims to demystify core npm workflows and give developers with various levels of experience a clearer mental model of how npm works behind the scenes. With the rise of AI-assisted coding, many engineers are shipping code that depends on npm without deeply understanding it. Meanwhile, seasoned developers often struggle with subtleties around publishing, dependency resolution, and security.This talk clarifies the install and publish lifecycle, surfaces modern best practices, and offers decision-making tools that help developers avoid surprises and regain control over their tooling.

You probably have faced a situation where you needed to debug something particular in your application. Something in a specific condition. These kinds of situations tend to be poorly handled by us developers.A common approach is adding a bunch of logs, deploying the code, and waiting for the logs to return. This is a very slow process and can be very frustrating.It would be much better if you could just get into the environment, while running, execute some code, and see the results. This is where the node:repl module comes in. It allows you to create a Read-Eval-Print Loop (REPL) in your Node.js application.Inspired by Ruby on Rails, which has a very useful console, I implemented a console in the application I was working on. It was a game changer. Now, we have a way more effective debugging/experimentation process. My team fell in love with it. Now, it's part of the app, as it always has been.Another good thing is that it was not hard to implement. The node:repl module gives everything. We just need to ensure the application is properly bootstrapped to use the REPL module.Table of contents<ul><li>The importance of tools and DX</li><li>The module node:repl</li><li>Hands-on: creating an iterative repl for debugging any application</li><li>Conclusion</li></ul>Takeaways<ul><li>Why DX matters and how to improve it through the development of custom tools</li><li>How Node.js modules can help with the creation of effective tools</li><li>Get to know the node:repl module</li></ul>

Feature flags seem simple enough: an on/off switch in your code. But as your team grows, the code gets more complex, and you add more flags, things can quickly go off the rails. Soon enough, you're wondering if a flag is safe to delete, why a toggle no longer in use is still slowing down your app, and why your React components flicker on every page load. This talk covers the three biggest problems I see JavaScript teams hit when scaling feature flags - and the patterns that actually work.

Search is evolving. As AI tools like Perplexity, ChatGPT, and Google SGE transform how users discover content, traditional SEO strategies fall short. Today’s web visibility depends on how well your site communicates with machines, not just humans.In this talk, we’ll explore the foundations of Generative Engine Optimization (GEO)—a new approach to building websites that surface in AI-driven search results. You’ll learn how to structure content for LLMs, create AI-friendly endpoints, and evaluate how your site appears through the lens of generative systems.We'll also walk through a live demo to show these techniques in action, with patterns you can apply regardless of your framework.

JavaScript is great, but it wasn’t built for high-performance tasks like complex data processing or 3D rendering. That’s where WebAssembly (WASM) comes in — a technology that can deliver near-native performance directly in the browser. In this talk, I'll show you how WASM can supercharge your web apps with a real-world demo, where it dramatically outperforms JavaScript in sorting a large dataset. You'll also discover how industry leaders like Prime Video and Figma leverage WASM for massive performance gains. This session will equip you with practical insights and best practices to integrate WASM into your own projects.

Whiteboards. Proof of Concepts. Pairing. Spikes. These are all tools we use every day to have high-level technical conversations about ideas we propose or approaches we think are the “right” way. As someone advances in their career into more experienced levels of software engineering, however, a critical skill becomes how you conduct and lead these conversations. It involves clearly articulating a vision and securing buy-in, while also valuing and integrating the diverse perspectives and feedback from your peers. The goal beyond each individual conversation is to foster an environment where ideas can be exchanged, discussed, enhanced, and decided on. You’ll walk away from this talk with some new, innovative approaches to try out that not only help get your technical ideas across but also solicit additional thoughts and opinions in ways that engage and effectively address different points of view.
