JavaScript Luzern #3

🚀 JavaScript Luzern Meetup

Hey everyone! We're planning for another evening of frontend goodness.

📋 What's on the agenda?

Coding the coder: how coding agents work - Hugo Sousa
You’ve probably already tried or are using on a daily basis a coding agent, such as Claude Code, Codex, OpenCode, Pi, etc. But perhaps you’re not aware of how they work. What is a coding agent? What does it take to build one? In this talk I’ll dig into the internals of coding agents and what it takes to build a minimal one.

The Browser Is Your Framework - Mateusz Halada
Let’s explore how modern web applications can be built directly on the platform using HTML, CSS, JavaScript, and browser APIs - without defaulting to heavy frameworks. Through a live demo, we’ll recreate common UI patterns and show what frameworks actually abstract under the hood. We’ll also demystify concepts like SPA, SSR, and CSR to understand where they truly come from. The goal isn’t to replace frameworks, but to give you the clarity to choose them intentionally—and know when you don’t need them.

🎤 Call for Speakers!
We still have open slots and would love to hear from you! If you've been working on something interesting — whether it's AI-related or any other JavaScript/CSS topic — reach out and share it with the community. Not sure what to talk about? We can help suggest a topic based on your interests. First-time speakers are absolutely welcome!

Food and drinks are on us.

A big thank you to CSS for providing the location!

See you there! 🙌
