form VS typescript-runtime-type-benchmarks

Also, ReScript Schema supports Standard Schema, a common interface for TypeScript validation libraries. It was recently designed by the creators of Zod, Valibot, and ArkType and has already been integrated into many popular libraries. This means that you can use ReScript Schema with tRPC, TanStack Form, TanStack Router, Hono, and 19+ more at the time of writing the article.

Tanstack Form: A lightweight form management library built by the TanStack team. Furthermore, it supports numerous other libraries like Vue, Angular, Lit, and more

When it came time to introduce a form validation framework to my previous company's app, we actually settled on TanStack Form. We took one swing at it, and immediately felt that the syntax was not for us. Sorry Tanner.

Spoiler: soon it will be possible to validate fields in the form validator too! See: https://github.com/TanStack/form/pull/656

If you want to support the development of the project you can contribute to the GitHub Repo as I'm doing. You'll also find some previews such as this PR which will extend the validation feature.

Tanstack - Tanstack has evolved to an entire ecosystem consisting of the famous Tanstack (or React) Query, Tanstack Table, now also Tanstack Router and Tanstack Form. It started with Tanstack Query, which adopted Nx and Nx Cloud. Zack talked about this collab with Dominik, and we also had Dominik on our Nx live stream. Now, all the above-mentioned Tanstack libs have adopted Nx, and there's more coming.

I’ve tried lots of form libraries, but none solve the burden of easy, rapid form building as well as RJSF does.

Yes. It's ~100 times faster than Zod and on par with Typia or Arktype (benchmark). But often, besides validation, you want to transform data incoming to your system, and here, ReScript Schema overperforms any solution existing in the JavaScript ecosystem.

Something cool that I can't remember if it was posted on HN at one point or I stumbled across when looking for alternatives to yup but this repo has been compiling a bunch of different benchmarks for runtime validation of ts validation libraries. Obviously to some degree the performance is arbitrary when you're reaching millions of operations per second but on the flipside their benchmarks are against rather data. Would be interested to see comparison of either more nested data or otherwise complex. Maybe something to look at in my spare time.

Any plans for web compatible output?

I maintain this repo, and we hand roll the stats page, but if we could get that for free it’d be so great!

Has been heavily optimized, both in terms of its types and runtime performance. Even including the static parser, many types are about an order of magnitude more efficient than equivalent Zod. Early results show it as marginally faster than any validator currently published to typescript-runtime-type-benchmarks, not including more complex cases where (2) would give ArkType a much more significant advantage.

Zod is a bit of an underdog but it is not fast, AJV which is slightly more common can validate and generate types too but requires using JSON syntax, TypeBox offers familiar syntax to Zod while still being JSON syntax in the background.

First, they're not fast (runtime type checking benchmarks).

Aha, so you're using a library in Java for this. You know about libraries in TS for this, there are plenty of them btw, but you don't use them because it's so easy. Express has `any` type for `req.body` because authors don't care about this either and it's so easy. And TypeScript is the one to blame in that you prefer to work with `any` type for incoming data rather than validating it.

It is so much faster than Zod that Zod basically doesn't show, https://moltar.github.io/typescript-runtime-type-benchmarks/ and according to bundlejs, https://bundlejs.com/?q=zod%2Czod%2C%40sinclair%2Ftypebox&treeshake=%5B*%5D%2C%5B%7B+default+%7D%5D%2C%5B*%5D&config=%7B%22analysis%22%3Atrue%7D, it is even smaller. I genuinely have no clue why Zod is this popular in 2023.
