Summer’s heating up, and so is ZurichJS.

On Thursday, June 19th, we’re bringing the sixth edition of ZurichJS to life with a server-sized dose of JavaScript energy. 🌞

This month, we’re tuning into the pulse of Node.js infrastructure and high-performance front-end frameworks. Expect:

• Talks that make sure you do not thrash the Node.js Event Loop 👊
• Front-end tricks to push your web performance to the max with Qwik ⚡
• Conversations with other JavaScript fans 🧠
• Good vibes and better ideas 🍻

The bar for high-performing websites keeps rising, and it's a critical factor for both user experience and search rankings. While achieving good scores is possible, it often requires significant effort and ongoing maintenance.

In this talk, I'll show how Qwik makes it easy to achieve top web metrics, automatically, even as your application scales.

We'll dive into Qwik's optimizer, explore the power of resumability and JS streaming, and uncover how its reactivity system works to deliver blazing-fast web experiences.

Deploying Node.js at scale is an art mastered by few. The most common problem is an exhaustion of resources that allows the application to denial of service itself. The result is Node.js systems that are massively overprovisioned, wasting enormous amounts of computing and memory - keeping most of them idle.

In this talk, we will do some math, discover hard truths, and implement a fix.

The Model Context Protocol (MCP) is a foundational layer for enabling interoperable, AI-native systems. In this talk, we’ll explore how to implement MCP servers and clients in JavaScript, focusing on the core structure of the protocol and how to enable communication between models and tools. Through practical examples, you’ll learn how to serialize context, handle events, and wire up components that speak the same protocol. If you're building AI tools or looking to integrate with model-driven ecosystems, this session will help you get started with MCP the right way.

Get ready to embark on a journey into the depths of TypeScript. We'll be exploring the often overlooked, yet powerful, features that lie beneath the surface of this versatile language.

But we're not just talking theory here – this exploration will be a hands-on experience. Each feature will be brought to life through real-world examples, all done in a live coding session. Join in as we shine a light on these secret TypeScript treasures and discover how they can elevate your coding skills to new heights. Recursive types, type permutations and a css validator written in typescript are just three of the cool topics we are going to cover during this talk.

What's all the hype with 'Vibe Coding'? How did it help me ship ZurichJS at lightning speed ⚡

In this lightning talk, I'll share how I created the entire ZurichJS platform in under 2 hours using AI assistance. Turns out you don't need to be in a Silicon Valley garage with lo-fi beats playing to achieve the mystical "vibe coding" state!

I'll walk through my journey from skeptic to convert as I built a full-featured platform including:

- Next.js with those fancy animations everyone loves 💫
- Backend infrastructure that actually works
- Sanity CMS integration (because content is still king)
- SEO-optimized pages (Google still exists in the vibe coding era)
- Analytics tracking (because what even happened if you didn't track it?)

No fancy prompts or "I whispered to the AI and magic happened" stories, just honest reflections on how my development approach evolved and what I learned by embracing this trend to get pragmatic with shipping things fast.

For developers wondering if "vibe coding" is just another buzzword or actually useful, come hear from someone who's shipped real code both ways! 🚀

Solving Real World Data Fetching Challenges with Next.js and TanStack Query: A Pragmatic Case Study 

Al is the next big thing. Machine learning models are interpreting the world and generative Al is taking over more and more of our tasks. And this makes us increasingly dependent on the big Al providers. What if we could use all this magic directly on our devices? Maybe even directly in the web platform, the largest platform for applications that has ever existed?
With WebAssembly and WebGPU, we have the tools to make all this possible.
It's time to get ready for some unexpected examples of how to use Al in the browser!
