QDD Mendix Meetup: An Open Space Meetup on Mendix Quality

Mendix, Wilhelminakade 197, Rotterdam, ZH, NL

An Open Space Meetup on Mendix Quality – driven by the community, for the community

Description

Join us for a special Mendix Community Meetup, hosted by the Quality Driven Development (QDD) initiative. Our mission: "Raise the overall quality level within the Mendix ecosystem"

This session will be an Open Space Meetup – highly interactive, collaborative, and community-driven. Expect lively discussions, fresh perspectives, and plenty of inspiration. Since we want to focus on increasing the quality awareness, this meetup is for juniors, mediors and experts. We all can learn, and we hope that you’ll go home with some inspiration about quality.

You don’t know the ‘Open Space’ concept? Here’s a short and informative YouTube video which perfectly explains this concept: https://www.youtube.com/watch?v=M_jhcvCYBbg. Please take a look at this before joining this session. But we’ll also explain the format before we start the discussions.

Note: This is an in-person event with no recordings.

Hack the Halls: A Mendix Christmas Bauble Mini-Hackathon 🎄✨ (NL Version)

Sopra Steria, Ringwade 1, Nieuwegein, NL

This Mendix Meetup brings a festive hackathon twist: you’ll design and style your very own digital Christmas baubles inside Mendix 11. Using only Mendix widgets and modern CSS (no JavaScript), guided by your own AI assistants like ChatGPT, Copilot, or Claude. You’ll learn how to create interactive, theme-aware ornaments that sparkle brightly on our shared Mendix Community Christmas Tree. This is the NL version, see here for BE version.

🦃 The Grand Prize
The organisers will make a selection. The audience will decide the winner by applause, measured with a decibel meter, and the loudest cheer will earn the champion a grand Christmas Prize. We may add additional prizes. A grading score form will be shared beforehand.

🎁 For Everyone
All participants will receive the final Mendix project containing the full list of baubles of all participants. That means you can take the magic home and sprinkle some Christmas love into your own production environment, right before December starts.

## Aim of the Evening...

Is to let participants discover how to use AI to create fancy CSS features and animated SVGs that can make any Mendix app look and feel beautiful. You will take this time to learn how to experiment with prompts, CSS (variables) and visual effects, guided by coaches and some community spirit.

***

## Takeaways

• 🎄 Style your Mendix app in a Christmas theme using only platform Mendix widgets and CSS (no JavaScript)
• 🤖 Practice vibe coding with ChatGPT, Copilot, or Claude to generate and refine CSS you can paste directly into Mendix (bring your own AI/Charged Laptop)
• 🌗 Build baubles that shine in both light and dark mode using CSS variables and theme switching in Mendix 11
• ✨ Get challenged to use modern CSS 2025 features like `:has()`, `light-dark()`, container queries, and cascade layers — and learn how to apply them with fallbacks for real-world use
• 🧑‍🎨 Learn practical front-end tricks: gradients, animations, conic patterns, focus states, and motion accessibility (`prefers-reduced-motion`), and how to use AI to do CSS magic, or any feature you’d like to experiment with
• 🌟 Take home the full starter project with all bauble templates, ready to bring festive love into your own Mendix production environment before December

• Starter project is mandatory: it will be shared beforehand and includes a starter setup, including CSS variable setup, and theme switch.
• Each participant must create a new Styling Module in the project for their bauble(s). Merge conflcits will not be resolved. Create your own bauble page, we can link to (e.g. Bauble_Wouter_Penris)
• Pure Mendix + CSS only. No JavaScript. If you really want to impress, you may build a second optional bauble with JavaScript, but this is not part of the main assignment.
• AI prompting is part of the challenge: vibe coding encouraged!
• Hand in your page by 19:30 to appear on the Mendix Community Christmas Tree.
• We will provide a top 20 list of possible baubles to create, such as snowy backgrounds, snow crystals, baubles, candles, and more, as inspiration and guidance.
