Also in brief: new Angular Space podcast episodes and articles, Micro Frontends, Native Federation v4, RxJS 9, and two Angular community deep dives.
Let's start with Optimus UI. In episode 26-17, we explained that PrimeNG, one of the most popular UI libraries, would become more of a commercial product. Because of that, a fork was created called Optimus UI, which keeps the library fully open source without requiring any additional licence.
Optimus UI was first published as version 1. Later, version 2 followed, aligning it with Angular 22.
Dominic Bachmann, who is one of the people behind OpenNG, which hosts Optimus UI but also other projects, has now started to organize a conference in Switzerland - in Lucerne to be precise.
NG Switzerland will take place on February 11-12, 2027. The call for papers is already open and ticket sales have also started. So, for us, that makes it the first already confirmed conference for next year.
Armen Vardanyan also came back from his summer holidays with his Angular Space podcast. We already had three different episodes: one about machine learning, another one about RAG, and another episode about Agentic UI, where I was also a guest.
So in the end, all three new episodes focus very much on AI topics around Angular.
Angular Space is not just a podcast, but also a platform where different developers can publish their articles. Recently, we got four new articles by Jaroslaw Zolnowski, Paweł Ostromecki, and Emmanuel Oyibo.

Stefan Haas, Senior Software Engineer at Microsoft, wrote quite a detailed article on Micro Frontends in general. He explains the difference between the Federation approaches - Native Federation and Module Federation - and iframes. He argues that large enterprise companies very often go with iframes, not because of performance - they are actually paying a performance price - but because of the isolation. That is really important when multiple applications have been developed for many years and don't work together so easily.
Stefan also mentions that the Federation approaches can be combined with Web Components. But again, that doesn't give you the same level of isolation that you find with iframes.
Stefan sees Native and Module Federation as a perfect fit, especially for greenfield projects, where you can define the boundaries and make sure that everything works together. And he also mentions another, newer alternative called Web Fragments.
All in all, it is a very good and detailed guide to the Micro Frontends landscape and the pros and cons of the various approaches.
Staying with Micro Frontends, Angular Meetup Graz also hosted a special online meetup with multiple talks around Native Federation version 4. So, if you are interested, you can check out those talks as well. The full recording is available on YouTube.
NgRx 22 is finally out. The headline feature is new experimental support for resources called Resource Extensions.
