We are launching Endform into early preview. With Endform you can run your Playwright E2E tests faster than anywhere else ⚡
We're looking for early customers to test with. If you've got a Playwright test suite that needs speeding up, send me a DM, I'd love to talk!

1/ End-to-end tests are supposed to give you confidence.
Instead, many Playwright setups create… chaos.
Here’s why (and what to do instead) 🧵

We've been using Endform for a few months at work. It's solid. I recommend it.
We just opened up Endform to public access 🎉 Come join the fun and run your Playwright tests faster!
You get 2000 test minutes for free in the trial, and it's $0.01 per consumed test minute after that.

We're launching a GoFundMe to cover legal fees to #FreeJavaScript trademark from Oracle.
We need to raise $200k to make full use of the discovery phase in the trademark cancelation petition. This is a critical step in protecting the JavaScript name for the whole community.

Just filed an issue to turn `--strict` on by default in TypeScript.
Maybe it's a little bit ambitious, but I'm excited for us to try this one. 😄

Proxies are so cool. We were talking about removing the need to use `createEffect` in 90% cases in Solid, and I was like "I think we can just proxy refs to avoid mounting effects".
Mizulu from Solid community went ahead and put a quick prototype together.

Symbol.dispose is the best thing that's come to Node.js lately. Love using it for test cleanup!
Write flat tests. No "describe", no scenario nesting, no beforeEach/afterEach hooks (as a rule). Each test case is self-contained, listing all the setup it needs. Use Symbol.dispose for reliable cleanup. Use granular test cases.
☝️ These things will make your tests shine.

Moving our marketing pages over from solid-start to Astro. Quite a shift in mentality, and I still need a few interactive solid-components in there, but it fits this use case really well.

Super excited for where we're at with Endform!
🖥️ The CLI and runtime are ready for testing with customers.
📊 The Dashboard is good enough to get people going. We'll invest a lot in making this the best test reporting dashboard going forward.
It's turning out so nicely! 😃

The new --erasableSyntaxOnly flag in @typescriptlang.org v5.8 doesn't work with the --build flag in monorepos using TS project references. How come? 🤔 We'd like to use it in the Endform repo, but only run tsc at the top level.

I just discovered pressing the Escape key from the login screen on a Mac will put it to sleep.
I've been wanting this for so long, because the "Sleep" command is not reliable. It just unsleeps itself instantly most of the time.
Lock + Escape in the future it is!
