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: https://t.co/7m8isYcMFy

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: https://t.co/54iY0XWVvP

@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.

[Andreas Söderlund @encodeart]

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

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

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

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.

We are live at 1.1.0 🎉

[Andreas Söderlund @encodeart]

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: https://t.co/gPtH8P5HFb

@hd_nvim Very good, the DCI architecture has expressed this in code for over a decade: https://t.co/K7bjt10mGy

[Andreas Söderlund @encodeart]

@ThePrimeagen Yes! Check out the epitome paradigm of that statement: https://t.co/K7bjt10mGy

@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)

[Andreas Söderlund @encodeart]

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