📢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/sveltek…
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/neutral…

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.

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