A behind-the-scenes look at running the "State of" series of developer surveys (State of JS, CSS, etc.) as well as lessons learned and upcoming trends.

Node.js continues to thrive despite claims of its decline. We'll debunk myths, highlight recent enhancements, and demonstrate its robust performance in today's tech landscape. The talk will cover Node.js's role in server-side programming and cloud-native applications, community contributions, integration of modern JavaScript features, and influence of emerging technologies. We'll conclude by projecting Node.js's bright future and growth areas in the evolving tech world.

The promise of the web is universal access to services across OSes and devices without gatekeepers, but like all systems, the web isn't what it promises – it's what it does. And today, the web is increasingly exclusionary. The roots of this exclusion are a mismatch between the reality of the hardware and networks users access our services from versus our expectations of those same devices and networks. The trends that put wind into JavaScript's sails on the client side in the early 2010's have long since stopped blowing.

In this talk, Thomas Steiner from Google Chrome's AI team dives into the various built-in AI APIs that the team is currently exploring. First, there's the exploratory Prompt API that allows for free-form interactions with the Gemini Nano model. Second, there are the different task APIs that are fine-tuned to work well for a particular task like translations, language detection, summarization, and writing or rewriting. After introducing the APIs, the final part of the talk focuses on demos, applications, and use cases unlocked through these APIs.

JSR is a community-driven, modern JavaScript registry with a mission to improve the ecosystem through transparency, openness, and innovation. Hear about recent developments, including the establishment of its governance board, ongoing projects and initiatives, and how these efforts directly benefit JavaScript developers. Discover how the community can engage directly, contribute to JSR’s direction, and get insights into the project’s goals and upcoming milestones.

Learn about Transformers.js, an innovative JavaScript library for running state-of-the-art machine learning models 100% locally in your browser. With support for nearly 2 000 pretrained models, spanning a wide range of modalities and tasks, Transformers.js empowers developers to seamlessly integrate advanced ML capabilities into their web applications. We'll also explore how we leverage emerging web technologies like WebGPU and WebNN to create interactive, privacy-preserving, and scalable web experiences.

Chrome DevTools just got a turbo boost! The Chrome DevTools team has been releasing new features at a furious rate over the past year, including  a complete Performance Panel overhaul with real-time Live Metrics and AI-powered Insights that'll expose bottlenecks you never knew existed. Forget tedious documentation searches and forum hunts; now, AI assists you directly within the Elements, Performance, Network and Sources panels, keeping you in the flow. Use the new alignment and collaboration tools to easily share your observations and debugging wizardry with your team and stakeholders, We'll unleash the full potential of these game-changing features, revealing hidden gems and shortcuts that'll transform your debugging workflow from a slog to a supercharged sprint.

Svelte 5 introduced runes which use signals under the hood. While signals are very cool and unlock a ton of composability possibilities they have their own gotchas... let's explore them while creating a reactive signal based system from scratch to really understand them from the base!

What if you could use multimodal LLMs to interact with websites or IoT devices using motion control?As advancements in multimodal AI offer new opportunities to push the boundaries of what can be done with this technology, I started wondering how it could be leveraged from the perspective of human-computer interaction.In this talk, I will take you through my research experimenting with building motion-controlled prototypes using LLMs in JavaScript.

Modern web applications need to be responsive and smooth, providing users with immediate feedback for their interactions. To understand how well our applications perform, we need to understand how browsers process and render content. This is why we now have AnimationFrames, a new representation of unit of work that powers INP and LoAF APIs!

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 talk narrates the journey of transforming this dream into a reality.

pnpm v10 added support for a new type of dependency called "Configurational dependencies". These dependencies make it possible to develop pnpm plugins and share your configurations between projects.

Let’s dive into the world of testing with Deno’s built-in test runner! Come on in, the water’s lovely!We’ll kick things off by exploring the principles of effective testing, perfect for beginners dipping their toes in. Then, we’ll introduce Deno’s out-of-the-box test runner.With the Deno.test API, you’ll be jetting in no time. We’ll cover how to write assertions and see firsthand how they help ensure your code behaves as expected.To wrap things up, we’ll explore writing tests that will be familiar to those experienced with Jest and Vitest, using Deno and its standard library.

In modern apps we have millions of lines of code with data coming from a variety of data sources. To achieve swift user experience using a suspense-like pattern is non-negotiable. Only if there's something that could manage the complexities in suspense with prefetching, waterfalls, data dependencies, etc. How can we make suspense more resourceful?In this talk we'll see how templating and signals make the suspense pattern a breeze in Angular.

AI progress is running away on the server-side, where the GPUs live, but the web platform is never that far behind. In this talk we're going to explore the incredible applications you can build in the browser today and in the near future.You'll see how to build an offline-capable, speech to speech language translation app, a babelfish, using nothing but the web platform. Through this app we'll explore the different ways we can run AI models in the browser today and what may be built into the browser in the future. From low-level standards to high-level experiments, you'll learn how to work with AI on the web.

The European Accessibility Act (EAA) is coming, and companies will rush to certify their websites as accessible in the easiest way possible. But high Lighthouse and Axe scores don't mean real accessibility. Many will rely on these tools to "prove" compliance, despite their critical blind spots – broken focus, misleading ARIA, and inaccessible dynamic content. Even more confusing, Lighthouse and Axe are built on the same foundation, yet they can produce different results.

Signals have been revolutionizing state management lately, offering a more intuitive and performant approach than traditional methods. But what kind of magic is there under the hood? You change a value, and all places that use that value update and recalculate themselves automagically… 🤔In this talk we will look behind the curtain and explore the inner workings of Signals, by building our own implementation from scratch (Disclaimer: use for learning purposes only 😉).Signals have become almost a de facto building block in JavaScript frameworks lately, with some notable exceptions (looking at you React 👀), so it really pays off to have a deeper understanding about how they operate, how to debug them effectively and how to avoid common pitfalls. Plus, who doesn't like a bit of live coding?

This is the story of how I almost spent a night on the street — because of JavaScript's Date object! We'll dive in and try to understand why that happened, and how to prevent it. Luckily coming soon to a browser near you is Temporal, the JavaScript built-in API that makes this kind of mess-up a thing of the past.

In the TV series Knight Rider, the concept of an intelligent car was pure sci-fi. Over 40 years later, we now have the tools to bring it to life - purely in the browser. This talk explores combining AI techniques like RAG and function calling with advanced browser APIs (e.g., WebBluetooth) to create a browser-based AI agent with personality, memory, and autonomy, powered by WebAssembly and WebGPU - fully offline and privacy-preserving!
