📢Introducing ArkRegex📢 a drop in replacement for new RegExp() with types ⬇️

With the help of @GitHubCopilot, its Agent mode (with Claude Sonnet 4.5) and the GitHub and Svelte MCP servers, I just fixed 10 Superforms issues in a few hours of work, and when I say work, most if it was waiting for the changes to be completed, and clicking allow for terminal prompts. The convenience and speed of this was unparalleled to anything I've seen in my 25 years of professional programming: - It worked through very complicated Typescript typing problems due to third-party library updates, kept iterating until it finally was fixed. - It searched through the Zod 4 source code to figure out exactly how to override its JSON Schema generator for types not directly representable in the specification. - It added such a simple fix to a component to get compatibility between different Svelte versions, so simple I wouldn't think of it. - For each step it added detailed test files, covering so many more cases than I would think of (or even bother to write). I became more and more lazy/convenient when I realized how powerful it is, so in the end I just told it something like "Analyze issue 617 and come up with a fix". And almost always, it did. Changelog so you can see what it fixed: github.com/ciscoheat/svel… I can't believe I wrote/edited not more than 10% of the code in all those commits.

Creating a SvelteKit cross-platform native desktop app wasn't that hard with the help of @NeutralinoJs! I made a template to make it as easy as possible to get started: github.com/ciscoheat/neut…

@housecor Thank you for sharing! Great overview, it's hard not to fall into "the paradox of choice" though, when there are numerous products available that do almost the same thing.

I think sync engines are the future. These slides show why. dropbox.com/scl/fi/ofac1vo… Slides from “Write Now, Sync Later” that I just presented at KCDC.

@bonclairvoyant Glad it's being used! It's hard to know the usage stats for the myriad of features, so thank you for notifying!

@encodeart the stickyNavbar option in Sveltekit superforms is such a convenient feature. Thank you!

It's a great day for form validation! With the 2.27.0 release of Superforms for SvelteKit by @sveltejs, the super-trio of validation is ready for you: Zod 4 and Zod Mini by @colinhacks, Arktype 2.0 by @arktypeio and Valibot 1.0 by @valibot. Try it out at superforms.rocks!

2.4K ⭐️ Superforms is a SvelteKit form library 📖 that brings you a comprehensive solution ✅ for server and client form validation. @encodeart #ciscoheat/sveltekit-superforms&Date" target="_blank" rel="nofollow noopener">star-history.com/#ciscoheat/sve… #starhistory #GitHub #OpenSource

Introducing ArkType 2.1, the first pattern matcher to bring the power of type syntax to JS. Fully type-safe and up to 100x faster than ts-pattern🧵

@vivek_naskar "... but they were all deceived."

This is seriously getting out of hand.

@neversitdull Yes but never mind, you're so close to finishing your important project!

Your outie likes complaining about React and other frontend frameworks on Twitter. Your outie has registered over 300 domains. Your outie enjoys purchasing online courses, but never completes them. Your outie knows the difference between a font and a typeface.

This quote is completely reversing the argument. The threat is, just as Sagan says, a small group of people using technology to profit and benefit themselves first and foremost. That's what people worry about. As long as there is profit to be made on war, health issues, the destruction of nature, etc, science is nothing but a tool to be used in that way by the elite, and the objective [sic] scientists are nothing but immoral machines waiting to be replaced by AI.

Carl Sagan saw this coming decades away.

We are live at 1.1.0 🎉

Superforms has gotten some flak lately since it can be a bit too much for simple forms. But remember that you can use it just on the server, and roll your own solution on the client, which is especially easy with Svelte 5. Check out how it's done: sveltelab.dev/rge07lq1b2ouw2…

@hd_nvim Very good, the DCI architecture has expressed this in code for over a decade: blog.encodeart.dev/dci-tutorial-f…

@ThePrimeagen Yes! Check out the epitome paradigm of that statement: blog.encodeart.dev/dci-tutorial-f…

@AaronBastani There are so many complains about money but never about how it is created in the first place. (No, it's not "printed" by the central bank except 1% of it)

What are we offering our young people? Can’t get on the property ladder. Rocketing rents. £50k debt for a degree. AND you cant have any fun. Something will snap, eventually. And it won't be pretty.

One of the coolest and most ambitious validation libraries, give it a try for some next-level typescript wizardry.

🚀 Simplify form handling in your SvelteKit apps with Superforms! 🌟 Supports Zod, Yup, Joi, and more for powerful validation. Build faster & better. 👉 GitHub: github.com/ciscoheat/svel… #SvelteKit #WebDev #Forms #JavaScript #TypeScript #OpenSource #Coding @sveltejs

Which one do you focus most on in your system?

Superforms 2.22.0 brings you a a PR from the creator of Zod himself, @colinhacks, and feature from the very latest SvelteKit (thanks as always, @sveltejs), so now you can send any type of data with the form. 🎄 Merry Christmas! 🎄
