SWR VS react-hook-form

Following is overview picked from SWR site.

If you need more robust features—like caching, re-fetching, or pagination—check out libraries like React Query or SWR. Many of these tools also offer optional Suspense modes, so you can keep your data-fetching code clean while benefiting from powerful caching and refetching mechanisms.

Client-Side Data Fetching with useQuery can be used for interactive components that need to fetch data on the client-side, with initial state hydrated from server-side fetched data. For fetching data that changes frequently or for adding client-side interactivity it is useful the useSWR strategy. It’s a React hook for client-side data fetching with caching and revalidation. It allows fetching data on the client side, usually after the initial page load. Nevertheless, it does not fetch data at build time or on the server for SSR, but it can revalidate and fetch new data when required.

SWR for lightweight data fetching

We can do this with React-Query, SWR, Redux Toolkit Query and many others.

This is a common approach in JS land, and there are plenty of libraries that help abstract the logic and make sure the state is consistent, like swr or TanStack Query.

SWR is a React Hook for data fetching that makes it easy to fetch, cache, and revalidate data at the component level.

We’ll be using Zod and drizzle-zod for schema validations in forms. Zod is already packaged on the demo application along withReact Hook Form and Zod resolver for React Hook Form. So, go ahead and install drizzle-zod. And also drizzle-seed that is Drizzle's handy package for seeding in development:

Yup provides you with a declarative way to validate form data in JavaScript apps. It has a set of features which make it a flexible and efficient choice for handling validation in React, React hook form, and other frameworks.

"Instant" can mean different things to different people.

I have an HTMX/Flask/Bootstrap app that feels instant for most requests on the LAN, except when it doesn't.

Often React apps are pretty snappy, but if you want to do complex data validation on controlled forms, where the state updates for every keystroke, it can drag you down. There are good frameworks for doing uncontrolled forms in a disciplined way

but it's another thing to add to your bundle. React is also not fast enough to do animations so you have a lot of .show/.hide (or display: none) CSS has facilities to do transitions and animations that are pretty good but I always find it a little nervewracking for a JS application to have state in React state variables and any other kind of state. Some ImGUI frameworks have components that look superficially like React components but are fast enough to animate every frame, which makes me feel like I am in control and get the animation to look exactly what I want.

Leverage Libraries: Sometimes, the complexity of forms might require more advanced solutions. Libraries like Formik and React Hook Form provide additional tools and patterns that can simplify the process.

We will use NextAuth later in the article, so install that also.

React Hook Form is a lightweight and fast form validation library that integrates well with Next.js.

We'll use React with Vite, shadcn/ui (a collection of reusable components I have been wanting to try for a while), React Hook Form for form management, and Zod for schema-based form validation.

You want to do all this without writing a bunch of duplicate code and, in this case, without a third-party form library like React Hook Form.

Creating a robust and user-friendly contact form is a vital part of any web application. A poorly implemented form can lead to user frustration, data inconsistencies, or even security vulnerabilities. Leveraging React Hook Form and Zod simplifies this process while ensuring a seamless experience for both developers and users. In this article, we'll explore why these two tools are essential for building contact forms and how they address common challenges in form development.
