What libraries do you miss from other frameworks like Vue or React?
Don’t know if it can help, but I discovered this only recently, which was really missing for me with svelte: https://felte.dev/
- Introducing Skeleton - a Svelte UI component library for creating web interfaces using Svelte + Tailwind
- Client side form validation

Shadow DOM, Firefox and contenteditable
I’ve been experimenting with web components in order to build a wrapper for Felte that can easily be used with vanilla JS. One of Felte’s features is the ability to use custom field components that are not based on the browser’s native inputs (input, textarea, select). The example I show is a div with an attribute [contenteditable=“true”]. While testing this experiment I found some weird behaviour coming from Firefox: while I could perfectly click each field and type of it, if I tried to use the form only using the keyboard (tabbing to each field) the focus moved but trying to type would always result in the text being added to the first field I focused.

The use:__ feature giving my editor TS errors, but it works
There’s an example on Felte’s repo setting this up!

Using native form with web components + felte no data being passed
Ah. Of course 😅. mwc-textfield is not a native input. Felte relies on native inputs. You can use createField (by creating your own "wrapper" Svelte component that will render your ) or... better yet... you can experiment with what I've been working for the past weeks.

Creating a Chai like assertion library using proxies
For the past few weeks I’ve taken the (arguably pointless) work of migrating Felte from using Jest to uvu. This is a really tedious work by itself, but one of details that would have made this work even more tedious is that Jest prefers assertions to the style of expect(…).toBe* while uvu gives you freedom to choose any assertion library, although there’s an official uvu/assert module that comes with assertions to the style of assert.is(value, expected).

Converting React Forms to Formik and Yup
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.

Crafting Forms in React: Vanilla vs. React Hook Form vs. Formik
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.

Using React Select with Formik
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.

A simple Vue form validation composable with Zod
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.
-
validation ???
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.

Enhancing Redwood: A Guide to Implementing Zod for Data Validation and Schema Sharing Between the API and Web Layers
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.

Creating a form In React Native With Formik
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)

Authentication in Next.js with Supabase Auth and PKCE
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.

The DynamoDB-Toolbox v1 beta is here 🙌 All you need to know!
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 🙈).
