I recently got to hang with the creator of Valibot, Fabian Hiller on a live stream.
The history of Valibot
Here's a highlight from the live stream that summarizes the history of Valibot is if video is your jam. If not, read on.
During his thesis work, developer Fabian Hiller found himself with dedicated time to pursue an idea he'd been mulling over - creating a new modular data validation library for JavaScript. This led to the birth of Valibot.
Hiller had previously worked on modular forms, but he wanted to bring that same modular philosophy to data validation. While popular validation libraries like Zod offer excellent APIs, Hiller felt there was room to take modularity even further.
"For Zod, it doesn't make sense to make it extremely modular as Valibot, because most Zod users love Zod for its API," Hiller explained. "This would probably be too big of a breaking change."
Instead of trying to rebuild Zod from the ground up, he decided a fresh start made more sense. Valibot aims for ultimate modularity, allowing developers to compose small, reusable validation units together.
Hiller didn't work in isolation. He reached out to Zod's creator Colin McDonnell, but the timing didn't line up for deeper collaboration initially. Hiller remains in touch with McDonnell and other open source maintainers though.
"I'm sure improvements I made in Valibot will hopefully improve other libraries, and other libraries will hopefully affect and improve Valibot," he said. "I hope at the end we end up with great open source projects, and the community can choose what they prefer."
With Valibot, Hiller hopes to provide developers a new, composable approach to data validation. And by cross-pollinating with other libraries, he aims to push the entire JavaScript validation ecosystem forward.
A First Look at Valibot
If you want to experiment with Valibot, I recommend you check out the Valibot playground. Fabian actually made a change to enable prettier support after our live stream! 🤩
Also, version 0.31.0 was recently released with a whole rework of the API.
Let's start of simple. We want to create an e-mail validator. Valibot makes this pretty easy for us.
import * as v from 'valibot';
const EmailSchema = v.pipe(v.string(), v.email());
const validEmail = v.safeParse(EmailSchema, 'jane@example.com');
console.log(validEmail);
First, we import the Valibot package. Next, we create a schema for a valid email, const EmailSchema = v.pipe(v.string(), v.email());
v.pipe is so powerful. It allows us to chain validators. First, we check that the input is a string via v.string(), and next, if it's a valid email via v.email().
If you run this in the playground, you'll get the following output.
[LOG]: {
typed: true,
success: true,
output: "jane@example.com",
issues: undefined
}
You can view the following example in this Valibot playground.
Let's see what happens when we have an invalid email.
import * as v from 'valibot';
const EmailSchema = v.pipe(v.string(), v.email());
const validEmail = v.safeParse(EmailSchema, 'janeexample.com');
console.log(validEmail);
If we run the updated playground, it will now output the following:
[LOG]: {
typed: true,
success: false,
output: "janeexample.com",
issues: [
{
kind: "validation",
type: "email",
input: "janeexample.com",
expected: null,
received: "\"janeexample.com\"",
message: "Invalid email: Received \"janeexample.com\"",
requirement: RegExp,
path: undefined,
issues: undefined,
lang: undefined,
abortEarly: undefined,
abortPipeEarly: undefined
}
]
}
You can view the updated example in this Valibot playground.
If this were running in an application, it would throw, so we'd want to handle that. You can see an example of that in a recent pull request of mine.
feat: enabled loading an existing conversation in StarSearch
#3563
Description
Now you can share an existing thread (conversation in StarSearch). We had a rudimentary version of this previously (see #3324), but it was just sharing the prompt and running it.
These shared conversations are the full conversation that gets replayed and does not hit our AI backend at all.
If you are not logged in, you will only be able to replay it once (unless the page is refreshed in the browser) and any other actions will require you to log in.
One thing to note is if you generate a shared URL, it will generate for beta.app.opensauced.pizza on beta and deploy previews, and one in prod, will be prod links. All that said, you'll just need to replace the beta base URL with the deployment preview URL.
TODO:
- fix flash of content when loading a conversation
- fix OG image for a shareable StarSearch conversation- fix Server-side request forgery warnings
Note: This PR adds Valibot to the project. It is MIT licensed and a small package (1kb). It's used for some validation in this PR and I plan to use it elsewhere in the application long term.

Steps to QA
Here's a few share links you can try:
Associated OG image, https://deploy-preview-3563--oss-insights.netlify.app/og-images/star-search/?id=900686cc-8926-47fd-a1d6-0e19da967f48
Associated OG image, https://deploy-preview-3563--oss-insights.netlify.app/og-images/star-search/?id=ff9b26b7-64e7-460b-9d33-252543bee24d
- Note that the StarSearch page without a shared conversation, should load the normal OG image, https://deploy-preview-3563--oss-insights.netlify.app/og-images/star-search/
--
Also try and create a new conversation then try to share it.

Wrapping Up
We only scratched the surface of Valibot, but I encourage you to check it out. Valibot was highlighted in the latest bytes.dev issue, VALIBOT AND THE CIRCLE OF LIFE. You know a library is gaining traction if bytes.dev covers it!
If you're interested in the catching the recording of our live stream, you can check it out below.
Stay saucy peeps!
