[VIBE CODE WEDNESDAY] is a weekly gathering of people, hosted by weXelerate, where we are building things with AI — and we'd love for you to join us. Here's the idea: everyone has a mile-long to-do list and a bunch of ideas they never get around to. Things that don't get scheduled don't get done. So we made it a thing. Every Wednesday at weXelerate in Vienna, we block off the time and vibe code together. Think of it like your weekly gym session — except instead of lifting weights, you're finally building that thing you've been putting off for months. Two reasons people keep coming back: you actually get stuff done, and you're not alone in the room and meet new people. Someone next to you just found a tool you've never heard of or you get honest feedback on your idea. That kind of casual knowledge sharing is hard to find — and it happens naturally here. From pros to newbies everyone is welcome. No experience required. No pressure. Just show up and build. Wednesdays @ weXelerate, Praterstraße 1, 1020 Vienna

**Our next show:** [next improv Show](https://www.iicv.at/improvshow) **Leader of the session:** [IICV Calendar](https://www.iicv.at/event-calendar) **What is it ?** An open improv session for all experience levels.

After that, you can: * share your achievements or pet projects (informal, just at the table) * get feedback or inspiration from others * or simply work on your own project alongside the group Bring your laptop (or any device you like to code on) if you want to actively work. Or just come by to connect and get inspired. Please try to be on time so we can kick things off together. Looking forward to seeing you there! 🚀

🎉 Get ready for the **Angular Vienna x MRDS Vienna Joint May Meetup!** This time we partnered up with our friends from **MRDS Vienna** ([meetup.com/reactive-vienna](meetup.com/reactive-vienna)) to bring you an amazing evening of **talks, networking and spring energy**! Expect deep dives, practical insights, and plenty of time to connect with the community. **What's on the agenda:** 🗣️ Expert speakers 🎓 Knowledge sharing on the latest in Angular 🎫 Raffles with cool prizes 👥 Meet old and new friends from the community 🍻 Free drinks 🍕 Free food 🎉 Open-end networking ✔️ Just RSVP! **Location:** LEAN-Coders, Hainburger Straße 33 **Agenda:** 18:00 – Warm-up 18:15 – Meetup Intro 18:30 – Dominic Bachmann 19:15 – Pizza Break (30 mins) 19:45 – Robert Maier-Silldorff 20:30 – Break (15 mins) 20:45 – Raffle 21:00 - Outro & Open-End **\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 🗣️🗣️🗣️ Talks 🗣️🗣️🗣️ \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-** **Robert Maier\-Silldorff \- iteratec \| [LinkedIn](https://www.linkedin.com/in/robert-maier-silldorff-71464ab2/)** **Microfrontend-Plugin-System: Architecture, Challenges, and Lessons Learned** This talk shares the story behind a microfrontend-based plugin system we built for a large enterprise customer. I’ll cover why we chose a plugin architecture, how the system is structured, key challenges we faced and how the solution has evolved over time—ending with lessons learned for building extensible frontend platforms. **Dominic Bachmann - [LinkedIn](https://www.linkedin.com/in/dominic-bachmann-645267319/)** **From Typos to Type Safety — Building a Typed Router for Angular** 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. **\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-❤️🤝❤️ Sponsors ❤️🤝❤️ \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-** **PushBased** PushBased is a close-knit group of IT experts offering their knowledge and services in #Angular #RxJS #NestJS #JavaScript #TypeScript #webperf #Nx and more.

Also, bring clean indoor sports shoes, your racket and a water bottle with you. There is a drinking fountain available if you need to replenish your bottle. If you do not have a racket, it is possible to rent rackets from the club, if necessary (3€). Sometimes the host or other members have spare rackets - please ask in the comment section below! If you are joining our events for the first time, WELCOME! Let the host know that you are new and they will find a place for you. Don't worry, we are an open and friendly group.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
