Same `User`. Same rules.
The surprise? Making 7 approaches mean the same thing was harder than making them compile. 😹

Caching. Wenn du dich darauf einlässt, kannst du das bewusst triggern, sogar unter Python. Meine kompilierten Python-Files sind im Schnitt ~doppelt so groß, wie das py-File.
In JS probiere ich das gerade: wenn das funktioniert, deklassiere ich herkömmliche JS-Validierer wie Zod/ArkType.

I've been comparing 7 approaches to runtime validation in TypeScript. 🤔
Native TS, is-kit, Runtypes, Valibot, Zod, ArkType, typia.
Same `User` type. Same validation rules.
But making them behave the same was harder than making them compile. 😹
Full comparison next Wednesday! 🦐

Oh, yeah, Zod was pretty great, too. I ended up leaning a bit more on Arktype after I found it though.

ArkType rules in, valid fixtures out.
fromArkType(User) samples values that satisfy every rule, like 'string.email'.
Break one and you get ArkType's own message: age must be at least 18 (was 15).

A casual reminder that Data is perhaps the best way to generate values out of any Standard Schema-compatible schema library (zod, arktype, valibot, etc).
It's not just data but a built-in, ORM-like querying for it, too.
Testing!

i have a colossal list of projects that i earmark, only barely less than every single git project link i come across. i should totally mechanize this.
notably though it's usually things novel to me. so very obvious projects of interest get missed. examples today: arktype, valibot.

arktype is to effect schema as android is to ios
ioa has a walled garden and locks you in but also is a nice overall experience

I've been a happy user of Zod for the longest time. It rocks. But the 2.0 release of @arktype.io looks jaw-droppingly good... Maybe time to switch..... Not sure... Looks incredible!

I'll try a proper parser (i.e. no string.split("\n") nonsense) and it'll support things like grouping, comment formatting, documentation, deprecations.
What it won't be is an env file validator (beyond syntax violations) as people can use things like zod, valibot or arktype.
