TypeScript VS Yup

TypeScript公式サイト

There's also a slight performance caveat when it comes to interfaces vs intersections (&) to keep in mind: https://github.com/microsoft/Typescript/wiki/Performance#pre...

Tip: You can find official docs and guides at typescriptlang. org.

Node.js and TypeScript installed locally

Language: TypeScript (for type safety and better developer tooling)

It's extremely popular in React, Node.js, and full-stack TypeScript applications because it provides:

https://github.com/microsoft/TypeScript/blob/main/LICENSE.tx...

The license is Apache 2.0. With the trademark, they can tell everyone not to call their thing TypeScript but at this point, given the license, they cant't tell them not to copy it and change it and distribute that new thing (assuming the new distributors do so under the correct conditions).

But that is not the case, so you’d need a single cast to make it work (from number to ClampedNumber<1,200>) or however exactly you’d want to express this.

Tbf having looked more closely into how typescript handles number range types, I don’t think I would ever use them. Not very expressive or clear. I think I hallucinated something closer to what is in this proposal: https://github.com/microsoft/TypeScript/issues/43505

I still think that the general idea of communicating what acceptable input is via the type system is a good one. But the specifics of doing that with numbers isn’t great in typescript yet.

Validating API Response with Yup Yup repo Response validation with Yup

Support Yup, Zod, AJV, Superstruct, Joi and others

NPM github/yup

Yup is a schema builder for JavaScript applications, it allows you to validate data against a schema and transform data in your applications easily. It was originally inspired by Joi, a popular validation library, but Yup is optimized for client-side use, making it perfect for form validation with React.

So far, we have managed the state of our order submission form, validated our form fields, displayed error messages,handled form submission, and tracked visited fields. However, there is an even better way to carry out form validation, and that is through the use of a library known as yup. With yup, we can eliminate manual interference from our validate function.

One of the most basic applications of ReScript Schema is parsing - Accepting unknown JavaScript data, validating it, and returning the result of your desired type. There are dozens of such libraries, and the most popular ones are Zod, Valibot, Runtypes, Arktype, Typia, Superstruct, Effect Schema, and more. Also, even though this is slightly different, validation libraries like Ajv, Yup, and others also stand really close.
