add unknownutil validator

[ryoppippi]

Hi! I created a middleware of unknownutil (https://github.com/lambdalisue/deno-unknownutil) This is kind of a zod or valibot, but so much faster and lighter!

Hi @ryoppippi !

Thanks for the PR. I didn't know unknownutil!

I'm curious about one thing. It seems to me that unknownutil only validates Types. So, in practice, it can only be used for "JSON". zod and valibot will validate the actual value. Examples, length of string, whether it is an email or not.

z.string().length(5);
z.string().email();

But unknownutil only handles Types. Honesty, I'm not a fan of calling it a Validator, what do you think?

Hi @yusukebe Thank you for checking and reviewing my PR!!

As you mentioned, unknownutil validates only types. It is not a "data validator" but "type validator". The bundle size is so tiny and it works really fast.

I'm a huge fan of Hono RPC. Recently I've been using unknownutil with Hono for typing. Although unknownutil lacks some features like length or email, It is quite useful for simple API. For this purpose, I only need to type the input and check the type and keys. So data validation like zod or validot is too much for that purpose.

If you do not think this is a validator, I'll close this and create an independent repository.

PS: lizod is a similar type of validation library. This also only validates type

Hi @ryoppippi,

Thanks for the explanation!

I understand well that unknownutil is not a data validator but a type validator. I also understand that you prefer to use unknownutil.

However, I would like to reject this PR, because most people imagine an actual data validator when they hear the word "Validator".

If you do not think this is a validator, I'll close this and create an independent repository.

When you create your repository, you can add the project to this page!
