Let's figure out how to get form actions and React Hook Form to work together to get the best from both; client AND server side validation when JavaScript is enabled on the client, and user friendly server side validation when it's not enabled.

A bit verbose but pretty cool! I'd definitely write some wrappers for handling all the zod stuff and mapping between formdata and objects, 100 line component for just an email form is a bit much. That's also why I don't like this component pattern with , I usually wrap this with a single component as well. It's great when a library uses it because you can wrap it however you please, but building inputs with more than one component gets tiring pretty fast.

This is exactly how we’ve been doing it in our next.js app router production application. Yes a lot of boiler plate but you get validation at client and the server and status messages sent back from the server to the user. I believe RHF is working on integrating with server actions / react server components which will reduce boilerplate and improve the api for doing all this.

Cool video Jack! I'm right now dealing with some forms in apps I'm currently working. Just a quick question: since Server Actions are handling the 'POST' request we are sending to the server, what's the purpose of adding the attribute `onSubmit` in the element? Isn't the attribute `action` handling the form submission? Looks like all the client side validation is being made with no problem even without the `onSubmit` attribute, from what I've tested. Thanks again!

ok sharing my workaround for this: i moved the client side validation to happen while the user fills the form, so it is not necessary for us to call the form.handleSubmit, and this frees the action behavior. steps: i deleted the "onSubmit" thing from the form and left only the action. then i changed useForm config to contain "mode: 'all'", for it to validate the form not only on submit, but also on blur and on change. and lastly i added "disabled={!form.formState.isValid}" to my submit button

I do it completely differently with react hook form, zod, useTransition and either server action or api route - the trick with server action is really that you do not need to return again the same messages you get from client side validation (my app requires js anyways, so I dont care about nojs) you just need to revalidate data against schema thats it. So I have beatifully working client side validation, with the same validation working on the backend.

If anyone gets this error "A React form was unexpectedly submitted. If you called form.submit() manually, consider using form.requestSubmit() instead," here's a fix. Rather than using a reference to submit the form, you can actually use the formAction (2nd array element when instantiating useFormState) as function to pass the submission data directly to the server action. You'll need to adjust your onSubmit function to accept data as its first and only param. This will still only execute once the validation is satisfied. Then, you can execute formAction(data). If you're iterating over your form entries in your server action since it was previously expecting FormData, you won't need to anymore. You'll actually get an error if you still do. Also, with this method you don't actually need the action prop on the form either since you're calling it yourself.

I really wish there were a better way to do all this, as it's quite a lot of boilerplate. Especially the part where you need to re-stringify the FormData to pass down the fields from the server if zod validation fails. For example, what if a field is of a numeric or boolean or some other type? Ideally you shouldn't have to convert those types yourself. You already have a zod schema, so it would be nice to reuse it. I've been tinkering with Svelte's superforms library and it's phenomenal. It gives you all of this for free, and it works with and without JS. Plus you get inline errors and auto-populated field data from the server. The only downside is that it only supports method="POST".

Question: How is the form resetting? I even downloaded the github code and ran on local machine. It does not reset form after successful submission. And how do i use function like form.reset()?

I think “works even if JS disabled” was a bad marketing plan for a front-end first JS framework. I guess what Vercel and React team trying to pull off is, even JS interactivity is not your first priority, you can still build pages like PHP or similar backend languages (currently what Astro does with official React solution). In other words, steps up and makes a bold move in order to have a better position in the market. NextJS is not taken seriously as a backend solution although it’s a fullstack meta framework. I believe these improvements might change that. By the way a great tutorial as always Jack. Too much boilerplate IMO and I believe soon there will be a more compact solution (by the help of react hook forms I hope) but it’s good to know we’re getting there.

@stancobridge

@jherr Normally, I get the previous state, when the form is submitted and I don't call reset from useForm, the form state remains unchanged, the need for access to the old values is because the server action removes the Value when the browser refreshes. Secondly, I don't need to use hidden inputs to set values after building a component that handles this for me and I can just call setValie to do the rest. Say I have a component that holds crops image and send the value of the cropped image to hook from just calling setValue, why will I need this. RSC is great, React 19 is cool, but trying to use it to replace everything, creating problems that shouldn't exist in the first place or taking us back to the period where we needed something like react to escape all these is not cool, am yet to understand what it solves. Can't I just send the values from useForm to the backend without these extra codes

​@@jherr If i'm not mistaken in your video we assign each input field to a state, making it a controlled. So every key stroke in a field causes a re-render. So the performance gains for using RHF is then lost?
@jherr
@jherr 3 ай бұрын
​@@Tommy-ev6gv I'm not sure that these inputs are controlled. I'm destructuring {...field} into the inputs, and that could just be managing refs. The example is just following the boilerplate code for form inputs provided by shadcn in their react-hook-form integration section. That wasn't the primary point of the example or the video, which is primarily concerned with keeping the client-side validation functionality of RHF while still leveraging `useFormState`. I'm also not particularly worried about the performance impact in this case because re-renders in React are expected and in this case would not result in DOM updates even if the inputs were controlled. React leverages a VDOM to ensure that the DOM is never unnecessarily updated. Renders don't updated the DOM directly. Renders create VDOM nodes which are diffed against other VDOM nodes and the DOM is only updated when there is a delta between the old and new tree.

Hm, I get this error: Error: A React form was unexpectedly submitted. If you called form.submit() manually, consider using form.requestSubmit() instead. If you're trying to use event.stopPropagation() in a submit event handler, consider also calling event.preventDefault(). Any idea what might be causing this?

I think that's a transient HMR issue. Try hard refreshing the page without a form resubmission.

Thank you for the suggestion and the excellent videos! I will give it a try. It appears that this approach is not well-supported currently. It seems that to achieve progressive behavior, one should focus on server components and avoid client-side stuff. However, having client-side validation feels so good! I'm sure that this area will evolve as the development of the framework continues. Keep up the great work!@@jherr

That will work fine with JavaScript enabled. It won’t work if JavaScript is disabled. If all you need is JavaScript enabled support then that works just fine.

I do not get it. How is this usable in real senarios?. What I am I missing here? This seems like we are back in the 2000s. What is the issue we are solving ? Multi-step, conditional fields, dynamic fields... this is going to be a maintenance hell in my mind. I am not getting the value proposition of nextjs here. There are clearly better battle tested ways for this.

What do you mean? This demo shows how can you get client/server-side validation using RHF, Zod and React. You don't have to use Nextjs, but it's a popular fullstack framework.

This is how react prepares to cover larger ground and step into backend game more and more. But of course I agree with you about larger multi step forms. This won’t be much of help. But for example a simple job application form or contact form will be working no matter what even visitor’s disabled JS. First thing NextJS solved was fixing empty html pages through SSR. And now server actions and helper hooks. It’s pretty new concept and obviously needs more time to become a mature solution. Yet they’re doing a pretty solid job IMO.

Not sure what you’re comparing this setup to because you don’t say, but it’s a lot easier than how you would do it in the older versions of next.js. Of course there are easier ways to make a simple form… you don’t have to do all this in next.js either. But if you want client and server validation with nice error messages then this setup is easy to replicate and gets you a long way for the amount of code required.

@Pete133 3 ай бұрын
Was there a way of getting both client-side and server-side validation and custom error messages with this little code in the 2000’s? (HTML validation doesn’t count as client side validation). Also how does this make maintenance harder? Genuinely asking to see if I can help explain or learn something.

this is completely incorrect as the browser will reload in the code provided. RHF is still drafting the support for server action. in the meantime I suggest to use form.trigger() on the onSubmit prop instead of a form ref submit

Jack you're a great resource for anything web development, and more. I however need to question the idea of supporting users who have disabled javascript as a worthy investment in a frontend experience, since it will come at a cost. The cost will be felt by the rest of your site's user base who have not disabled javascript. By supporting non-js experiences you will taking away resources that could be invested towards features and UX improvements for a much larger audience, the folks who have JS enabled. In 2024 should we still care about non-JS experiences? I say no, we're past that. If you want to support non-JS users, then you must make 100% of your site's UX be functional without JS, or at least the minimal amount to for a user to have the intended "user experience", and this is most likely a large investment, for how much gain? I don't see it worth the cost.

Way too overkilled. Server actions don't actually need a form data as input. That is just to handle an action directly from a form. A way better method is to just call the server action inside the submit callback. You can also wrap the code in a react transition to get the pending state.

Given the video description this approach was intentional-demonstrating how the server component model enables form functionality even with disabled JavaScript. Considering many sites don't prioritize JavaScript-disabled support, I concur that the video title "the right way" isn't optimal.

do you ever get Error: A React form was unexpectedly submitted. If you called form.submit() manually, consider using form.requestSubmit() instead. If you're trying to use event.stopPropagation() in a submit event handler, consider also calling event.preventDefault(). when submitting via: onSubmit={form.handleSubmit(() => formRef.current?.submit())} but when changing to .requestSubmit(), the form action no longer works...
