JavaScript Zagreb October Meetup @ MaMa

Hi everyone!

I’m excited to announce our next regular monthly meetup — it’ll take place at MaMa (Preradovićeva 18) on Friday, October 24th, starting at 6 PM.

We’ve got two great talks lined up, and afterward, we’ll head over to "Cafe u Dvorištu" (Jurja Žerjavića 7) for some casual networking — as always, be sure to stick around!

Styling React Native
by Helena Andrašić

Forget CSS resets, specificity wars, and browser quirks. React Native takes a more direct approach to styling: everything is local, predictable, and powered by JavaScript. In this talk, we’ll unpack how styles are structured, how layout and composition work with Flexbox, and how to think about dynamic styling without relying on CSS. You’ll get a practical look at React Native’s styling model — how it differs from web CSS, what problems it solves, and what to watch out for when making the switch.

Goodbye jsdom/happy-dom, hello Vitest Browser Mode!
by Matija Marohnić

I got so used to unit testing my client-side stuff in jsdom/happy-dom that I forgot that I'm ultimately still pretending that I'm in a browser, and just how limiting that is. With Vitest Browser Mode you get to test a bunch of stuff you weren't able to while testing in Node.js, and discover bugs that only appear in actual browsers. Finally, find out what the difference is between Vitest Browser Mode and end-to-end tests.

See you all there!
