Learning and Development

AI is changing the way we develop software. Mattia’s talk takes a fresh look at **Type-Driven Development** (TDD), and how types facilitate not only the work of human developers but also **LLM reasoning**. The talk with be hands-on with code examples and open discussions Agenda: * What is Type-Driven Development * An overview of F#’s type system * How TDD facilitates human developers with AI tools * LLM Tooling with types * LLM reasoning with types * Compositionality and reasoning traces Mattia is a data scientist fighting a losing battle: replacing Python with languages featuring richer type systems. As the co-founder of Entropy42, a Zurich-based startup, he specializes in the verification of ontologies and mathematical optimization programs. There, Mattia leverages type systems and provers to sharpen the performance of specialized small language models. Mattia will use F#, but his talk does not require any prior experience with the language.

Hey Zürich, we are not slowing down! Angular Zürich is back with another evening of exciting talks exploring the future of Angular, modern developer experience, and where the framework is heading next. And for the first time ever, we’ll have three speakers sharing their insights, ideas, and real-world experiences with the community. **Talks:** *Even moar Angular skills for agentic development* *by Tomas Trajan* AI agents are quickly becoming part of the Angular development workflow - generating components, refactoring code, writing tests, and even orchestrating full features. But getting reliable results requires more than good prompts. In this talk, I’ll share the Angular patterns, architecture decisions, and tooling techniques that make agentic development actually productive at scale. You’ll see how strong typing, standalone APIs, signals, and clear project structure dramatically improve AI-generated code quality, and learn practical workflows for collaborating with coding agents without sacrificing maintainability or developer control. \-\-\- *From Typos to Type Safety — Building a Typed Router for Angular* *by Dominic Bachmann* Route enums, path constant objects, flat route trees to avoid nesting complexity — Angular developers have invented all kinds of workarounds to bring some safety to navigation. But they all share the same problem: a second source of truth that you maintain by hand. In this talk, I'll share how I built angular-typed-router, a drop-in replacement that infers every valid path directly from your route configuration. You'll see the developer experience in action — full autocomplete, compile-time validation — and learn how interface augmentation, template literal types, and recursive conditionals make it work at zero runtime cost. \-\-\- *Angular 22: The Great Simplification* *by Mateusz Halada* Angular has spent the last few releases removing complexity piece by piece - and Angular 22 takes that vision even further. In this talk, we’ll explore how the framework is evolving toward a leaner, more intuitive developer experience with simpler APIs, stronger defaults, and less boilerplate across everyday application development. You’ll see what’s new, what’s been streamlined, and how modern Angular patterns around signals, control flow, routing, and reactivity fit together into a much more cohesive mental model. By the end, you’ll understand not just the new features, but the bigger direction Angular is heading in. **Agenda** * 18:00 - 18:15 – **Intro** * 18:15 - 18:45 – **Tomas Trajan** \- Even moar Angular skills for agentic development * 18:50 - 19:30 **Dominic Bachmann** \- From Typos to Type Safety \- Building a Typed Router for Angular * 19:35 - 20:05 – **Mateusz Halada** \- Angular 22: The Great Simplification * 20:05 - 21:00 – **Networking**

**Let's talk! Parents with teens** **The reality:** Sometimes life as a family with teens gets complicated. We all worry about getting the classic eye-roll or push back. But if we don't talk to them, you both lose. Join our monthly "Let's Talk." We gather to swap stories, share what works, and find solid ground. **The impact:** Being a leader for your teen doesn't require having a perfect script. It is all about feeling anchored enough to start the conversation. When you lean into connection, you stop reacting and start guiding. #### What to expect * Real talk — come exactly as you are * Guided insights from the Wild Sense method * A breathing space to turn venting into value **Where & When:** * **Date:** Wednesday, 17 June 2026 * **Time:** 19:00 - 20:30 * **Location:** Rote Fabrik, Seestrasse 395, 8038 Zürich **[RSVP Link]** to let us know you're coming *(You are welcome with or without notice, but hitting the RSVP button helps us grab the right table!)* **Important: no perfect parents are allowed!**

As it is sometimes difficult in Switzerland to practice high german, in 2010 we decided to organize a conversation group that is free to everyone who wants to practice german and socialize. WhatsApp group for easier contact: https://chat.whatsapp.com/KmMkpiQxs291vTPv2RBNm4

### **Poolside Chats: Design, Research, Engineering & UX** Join us for a relaxed summer gathering at one of Zurich’s local Badis. This is a casual community meetup for designers, researchers developers, product managers, and other curious builders who enjoy thoughtful conversations, sharing ideas, and spending time outdoors. We’ll gather by the pool to discuss topics such as: * Passion projects * Design, technology, and product thinking * Ethical and responsible uses of AI * Creativity, learning, and experimentation * Personal philosophies and ways of working * Interesting questions about the future The format is intentionally informal. Feel free to join a conversation, listen, ask questions, or share something you’ve been exploring. Need a break? Take a swim, cool off, and come back with a fresh perspective or a new idea to discuss. This is not a recruiting event, job fair, or transactional networking meetup. While meaningful professional relationships may naturally develop over time, the purpose of the gathering is not to find clients, hire employees, or look for your next job. Instead, the goal is to create a welcoming space for genuine conversation, intellectual curiosity, and human connection. Bring your curiosity, a towel, and whatever ideas have been occupying your mind lately. \*Come to exchange ideas, not business cards.\*

No slides, no schedule. We're meeting up for a relaxed ZurichJS summer meetup with drinks, barbecue, and people who build things. If you’re shipping an AI tool, a vibe-coded side project, a SaaS product, or an existing app that could use a better business model, bring it along. We’ll hang out, compare notes, and brainstorm how to turn useful software into something that actually makes money. Let's get the bbq going with beers and geeks. Important: this is a potluck edition. Bring your preferred barbecue option (and maybe some extra to share if you want), some picnic blankets or picnic chairs, anything that you'd normally bring to a picnic. We're a big family at the end of the day 🫶 **Agenda** * None whatsoever **👉 [Event page](https://meetup.zurichjs.com/events/june-2026) \| Location Josefwiese** **About the organizers** * **[Bogdan Ilie](https://www.linkedin.com/in/ilie-bogdan/)** is a user advocate.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
