Yup VS TypeScript

Formik and Yup empower you to build robust and user-friendly forms in React. By leveraging their capabilities, you can streamline form management, reduce boilerplate code, and ensure a smooth user experience with clear and effective validation. Refer to the official documentation of Formik https://formik.org/ and Yup https://github.com/jquense/yup for in-depth exploration and advanced use cases.

On the other hand, Formik gives you components that you can mix and match to have fully working forms. Formik has builtin support for Yup for data validation.

I was recently building an application that, among other features, allows a user to submit chess players and chess games to a database. I was utilizing Yup for form schema and Formik for error handling, validation, and form submission.

Sometimes our use case might not require a full-blown form validation library though and we might already have a schema validation library installed in our project such as Zod or Yup. In that case, a simple Vue composable is all that is needed to provide a great form validation UX.

As for validation libraries, I would recommend Yup. With it you define your validation rules in a schema object which can be used where ever you need to do validation. It also integrates very nicely with react-hook-form which is what I’ve moved to using for any nontrivial forms.

I'm currently experimenting with the fantastic Redwood framework. However, while going through the excellent tutorial, I didn't find any guidance on using data validation libraries like Yup, Zod, Vest, etc. So, I had to do some investigation and came up with a solution. This article describes the implementation of validation with Zod in a fresh Redwood app. You can find the sources at this github repository.

Do you want to create a form in your React Native app but don't know how? Then this post is for you! In this post I will teach you how to create forms using a library called Formik , as well as how to integrate non-native form components with Formik. Additionally you will learn how to validate forms using Yup (which Formik supports out of the box)

The project has two authenticated pages - Home and Profile. Unauthenticated users can Sign In, Sign Up, Reset Password and Update Password. All of this is powered by Next.js app router, with usage of both Client and Server Components, and Supabase handling all of the authentication related functionality. Forms are built using Formik and Yup for field validation.

Similarly to zod or yup, attributes are now defined through function builders. For TS users, this removes the need for the as const statement previously needed for type inference (so don't forget to remove it when you migrate 🙈).

Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.

Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]

I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.

As a JavaScript or TypeScript developer, you might have come across the terms type and interface when working with complex data structures or defining custom types. While both serve similar purposes, they have distinct characteristics that influence when to use them. In this blog post, we'll delve into the differences between types and interfaces in TypeScript, providing examples to aid your understanding.

TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.

In this guide, we'll be extracting information from Amazon product pages using the power of TypeScript in combination with the Cheerio and Crawlee libraries. We'll explore how to retrieve and extract detailed product data such as titles, prices, image URLs, and more from Amazon's vast marketplace. We'll also discuss handling potential blocking issues that may arise during the scraping process.
