📰 The new era of component testing is here. It is time we talked. It is time you took a deeper look at the browser-like environments, learned how they actively harm your tests, and what you should use instead in 2025. Here's "Why I Won't Use JSDOM".

@tkrotoff I wish to unlock some of the RSC testing with cross-process request interception in MSW so you'd be able to load a component that relies on data/actions and test it in isolation (granted you also spawn the server part of this story).

@tkrotoff A single component cannot do that. You can write that logic in a single module, but it gets split on built-time into multiple things. Your best bet is to test that on an E2E level as a part of a user flow. That is too much expectations toward a single component.

@grow_love @heartereum It's flipped 90 degrees for that pattern to emerge.

@FletcherMR What is it with milk and cosmos? Ancient greeks were either world-building the foundation of fermented horror or had an unhealthy fixation on milk 🤭

@FletcherMR Lactic... Ga-lactic... Oh my we're on to something here.

@mehulmpt @amacarthur @bunjavascript TIL! Thanks.

@mehulmpt @amacarthur @bunjavascript None of those are forbidden in Node.js though.

* in the browser. You can still set all of those in Node.js because otherwise Fetch API on the server would make zero sense.

@oleg008 Regarding the roles, yes, you are likely right. Regarding pixel-perfect design, I find it be a waste of time and there's little anyone can do to convince me otherwise 🤷 It would make sense if design was about pixels. It's not. Never been.

@oleg008 Fair point. As I said, my view here is likely distorted. To make things worse, I don't believe in pixel-perfect design. I find it to be a waste of time. Design is never about exact pixels, it's about the overall experience of the product.

@oleg008 Maybe unpopular take from a lone OSS dev, but I'd rather hire a programmer that can design than the designer + programmer package.

@iuuukhueeee Oh, this is a good metaphor!

@oleg008 If I was working with a designer, I would expect a styleguide from them written in tokens, written in code.

@falsefalse cdassnames ftw.

Sonner by @emilkowalski_ has to be one of the sickest toast libraries I've seen.
