I present: playwright_ex
A simple Playwright client for #elixirlang.
Experimental.
Extracted from phoenix_test_playwright.
PRs welcome!
It's not comprehensive, because that's a daunting task (see playwright-elixir).
But it should be easy to add anything that's missing.

My offer still stands to match people’s donations. Send me a screenshot!
spoke with the executive director of my local food bank today and got this really incredible line: "if you donate 1 can of green beans, we can give away 1 can of green beans. but if you donate a dollar, we can give away 6 cans of green beans"

Just landed an ultra-rare +0/-0 PR. Yes, we merged this, yes it did something we cared about.

Many such cases. Life gets so much better when you rip that Bandaid off.
did a thing I've been dreading for months, to the point of waking up in a cold sweat about it.
it was, of course, easy. Took ten minutes. Had no emotional impact when doing it.
fuck do I hate brains sometimes.

#ElixirLang folks, I would *really* like my org's test suite to run with zero log messages printed unless there's a real error. How do you get to the Promised Land here?! Not all messages are deterministic, so if I fail CI due to logging, people get mad when it wasn't introduced by their change.

Hit off-by-1 errors in timing related tests when upgrading to Elixir 1.19. Turns out DateTime.diff changed subtly, it used to drop microseconds (everything rounded to seconds), now keeps them. Our tests relied on old behavior without realizing it. Hopefully saves ppl some debug time! 😅 #ElixirLang

It’s easy to hate on this, but from the product side, it’s hard to prioritize letting somebody create a bunch of data in your app that they’ll never be able to retrieve again.
Quick question. Why does literally everything require you to have an account.
Everything.
Everything.

At least 25 states plan to cut off food aid benefits in November
The pause in benefits for the Supplemental Nutrition Assistance Program would begin in states from California to Arkansas just before the busy holiday season.

“Did you hear about this hot new startup? They’re on track to becoming a Garfield in the next couple years.”
You can measure the economic value of something in Garfields. Garfield makes about 1 billion USD in revenue annually, so if an industry is smaller than that it's worth less to the world than Garfield

How do people handle required fields in LiveView?
My instinct is to mark it `required` in the DOM and let the browser's native UI say "hey, you forgot this" when the person tries to submit the form. But going that route, there's no way to say "actually you forgot these 3 fields."
