After getting help from another twitch streamer www.twitch.tv/fredkisss, it turns out that useOptimistic is the preferred solution, and it has to be used a specific way. I was doing this in my code (which didn't work) const [names, removeName] = useOptimistic( initialNames, (cur, name) => cur.filter((n) => n !== name) ); // in jsx { removeName(name); removeNameAction(name); }} > but instead I needed to do this: const [names, setNames] = useOptimistic( initialNames, (cur, newNames) => newNames ); // in jsx { setNames(names.filter((n) => n !== name)); removeNameAction(name); }} > for some reason, we can't have the filter occur inside the useOptimistic 🤷‍♂

Would love to see how remix could actually solve this problem. I’m not seeing it because the response of the server is out of synch with the db. The same thing would happen if we pushed out the data update to an hour in the future. The server is out of sync with the data that was just posted. an optimistic update AND no refetch triggered would solve this but it’s imperfect without a local cache that overrides what we know is invalid data on the db.

I know that this is a simplified reproduction of the issue, but I usually prefer to have a 'blacklist approach' when doing client-side removing (doesn't matter if we are talking about local-only data or in this case, an optimistic update), and instead of storing the component data prop in a local state, I store an array of unique ids that i don't want to show, and then i filter the data (with memo if needed) and render the result. In this way you: 1- don't have to store duplicated information (both the parent "state data" that is being passing down as prop, and the local state), and 2- if prop changes, you dont need to have extra effects to update your local state, since you are storing only a blacklist (again, an array of uniques ids) I think that an approach like this will solve your issue, since looks like this is "stale while revalidate" behaviour

@ChristianNaths

10 ай бұрын

THIS. The issue is that useState is being used incorrectly-the initial state argument is not intended to update the state after the initial render. Much better to take this blacklist approach suggested here, where you track only the unique identifiers of the items you want to optimistically remove from the list 👍👍👍 Tracking multiple copies of the same state makes your program more complex than it need to be.

Switched from nextjs to „remix run“ a while ago and never looked back

I observed that while utilizing the 'next 13' version in the development environment, I encountered significant delays in page loading during navigation. The loading times between pages were quite extended, ranging from 10 to 20 seconds. Furthermore, upon initializing the initial server, the loading time for the first page was even more prolonged, spanning 40 to 50 seconds.

Looking forward to the upcoming remix content. Its a great framework.

I’m doing the same for the same reasons, also the caching issue from your last issue. I’ve really enjoyed working with Next but the app dir has just been too frustrating. Remix seems to have a better grasp on the server/client divide.

I've added console logs and debuggers, the RSC does re-run and I see the new data getting printed. The prop in the client component gets old data.

How does your "getNames" function look like? I had a similar issue when I tried a local mock API (where the "DB" is a local const), as somehow the variable/module was cached (but not the data). When I switched from a local const to something outside of the module scope (like a database (SQLite) or an actual API), it started working.

getNames reads from a .json file using `fs`; it's an external data store

But the thing is that you’re hosting the state into a component that is not remounted when the route is refreshed. What you can do is actually put the same code into a sub component and put a key on the component that relates with the route, I think routes contain a key

I feel like these days people don't use nextjs because it's good they use it because they have to, just because of nextjs's community and toolkit

Eventually consistent and refetch immediately will not be solved easily by most frameworks. Either need to await the actual completion within the post (resolve a real promise), refetch later, or more complicated wait for a websocket notification. Also need something like react query’s refetch on focus to help this. I’d go with await the response and optimistic update the data rather than refetch immediately. The settimeout that doesn’t resolve as a promise is going to be a problem. This is all trying to get around a non transactional or slow db which I would solve first. If there’s a long chain of events before the transaction is complete a pending state should be stored somewher.

optimistic updates allow your UI to update instantly when you interact with it (and we assume the backend api request will be successful). If for whatever reason the backend request fails, we just revert the state change back to the original state and maybe show a toast notification saying something went wrong. If you don't do optimistic updates, a user with a lot of latency may have to wait 1 full second before they see their item get removed, and that's bad UX

NextJS 13 is such a mess. I feel like I should be using NextJS because ecosystem matters, but every time I (re)start down the path of using NextJS, I remember what drove me to Remix, which has been a wonderful experience. Nextjs caching is a constant source of friction for me, and even invoking simple actions is far more complex than is needs to be. I do wish Remix had Authjs support (Remix-Auth is works fine, but would feel better using Next-Auth for being battle tested), and Next has better HMR, and better community support delivering things like bundle analyzers, but overall, I find NextJS to be half-baked and overly complex.

So I think there are 2 separate problems here: 1. The setState(initialNames) not setting properly on the redirect 2. the data from an Api not getting fetched when the req. comes but in the moment you revalidate that route I don't think there is an easy way to work around that revalidation stuff. That's why we have to do a router.refresh() but because that is a client side refersh, react doesn't remount the other component, therefore the setState hooks initial value doesn't get set because it just rerenders the component, that's why we have to use the useEffect to update the state on changing props getting passed to the child. I think that problem is solvable by giving that Component a key that is going to change when the data is fresh (e.g. the initialNames.length) so that react actually handles is as a new component and therefore the useState hooks is getting run with the new default value

I know this issue man, it's not really a next issue, it's fundamental of how react works. I have ran into this plenty of times you need to set a key on your Other component. When it's re-rendered it doesn't know that the prop has changed. (think about when you map through an array, how you need to set a key for react to know that item is different from the others, and know when to render it.) When Page re-renders, and diff's the vdom tree it can't tell the difference from Other component with initialNames from how it was before, and how it was after initialNames object was changed. You need to force some kind of key onto it as if you are mapping throug list, so when Page re-renders it can tell Other component as changed in the vdom diff, I feel should fix your issue.

I think the router cache only caches the RSC payload, which is obtained after you call the revalidate path on /other at the end of the server action. Since your DB is not strongly consistent, the RSC payload contains the stale data, but that is what gets cached in the client only router cache. Even though you have optimistic updates on the client component, when the page is revisited, react will build the page from scratch, which is by constructing the server component from the payload cache, and render fresh client components which do not preserve the optimistic updates that you did a while ago.

both /gg and /other are RSC. The other route uses a client component for doing the optimistic updates. Revalidate path causes your frontend to rerun the RSC which re-runs the getNames call and passes it as a props to the client component. The client component should rerender because it was passed new props, but because I pass those props into useState (because I want to optimistically delete things), the client component never shows the updated view unless I add a useEffect and I need a refresh() called from the client component because the eventually consistent endpoint means that if I call revalidatePath in the server action, it'll cause the page to re-render too soon and fetch stale data.

@@deeperlayer I'm not sure I follow. I grabbed your code and added it, and I added back revalidate path. The moment you click on the X, it removes the item but then it adds it back in. So I'm not sure how you say this is working for you because it isn't for me.

5:34 you have to keep router refresh here because you commented revalidate path from your code. If you keep it, i think you dont need it router refresh. P.S. This is not tested from my end, it's just a logical statement.

there are other issues that occur when you add it back to the server action with the UI deleting the entry and then it adds the old list back

Once you Remix, you won't go back!

The true reason to use overwhelming React virtual DOM is to flex other frontend devs showing they know little while architecting the whole caching system with the help of AI 😂

@joshtriedcoding where you at? we need you to rip off this video and make it your own ;)

React's state management was designed by a 500 year old gold fish. Using a good state management library like MobX instead makes React so much better.

@@WebDevCody Here's what stood out for me in the video: you call out the issue at 4:37, saying "The prop is getting the latest data, but for some reason React is just not re-rendering it". If that is indeed the case (I can't verify myself so I'm gonna take your word for it), then the issue is that you're using that prop as the _initial state_ argument to your useState invocation on line 14. React will hold onto that value on purpose-the state you use to eventually render your UI, "names", will not receive the update you're expecting it to receive; it's not supposed to. That's why the useEffect workaround works, because you're forcing that new value into that state. My guess is that if you used that initialNames prop directly, your UI would update as you would expect. Great. Now all you have to do is figure out a different way to do the optimistic update to improve your UX, because the method you chose here has this inherent bug. Here's where @danihv's suggestion (in another comment) of tracking and filtering by a blacklist of unique identifiers would work great. Send a link to a repo and I'd be happy to send a PR with the changes. I try not to be too confident when I can't actually test out a solution, but from what I saw I'm pretty sure that's all you need :)

I think in the other page server component you add export const revalidate =0 It revalidate the component and use no cache

If your to dumb for Next im to dumb for Html

This has nothing to do with Nextjs, this is pure react issue. useState will only populate the initial props on the first render.

Yes but when I redirect between pages, wouldn’t you expected the useState to be cleared because it was a new navigation?

But why are people so hard wired to React. It's literally the worst renderer out there. We use Vue3/Nuxt3 and never had any issues. No performance tweaking, programming model is very consistent, easy to use and understand. So is Svelte and many others.

Instead of read have the write return the record.

the write is deleting the item from the database, so I'm not sure why returning the item I delete from the action helps in this scenario.

use the tag in the navigation, this will hard reloaded your route :)

The most problematic framework 2023

5:03 that has nothing to do with Next, a useState variable is never going to update based on initial props, that's React 101. You need to use the prop directly not assign it to a useState and expect it to change. If you need to assign it and want it to change you can change the key prop of the component, basically anything is better than placing a random useEffect.

@WebDevCody

it has everything to do with next. I setup the exact same layout using a SPA using react-router-dom, the page reloads with fresh data when lifting initialNames to the parent component and passing it down as props. The issue is Next is sending a cached version of the props when the page loads, which means the data I just fetched from the server is NOT passed to the component for it's initial render. It's not until the router.refresh() is invoked that it tries to pass the real value of props into my client component, but at that point it's too late because it's been cached in the useState(), which is why I also needed a useEffect. If next did absolutely no caching, this wouldn't appear.

@@dragosnc6604 It won't work even if Next would fix their problem, a nested component won't update a state variable initialized with props the component received if those were to change. The only way to do that is to change the key, or God forbids put initialProps in the dependencies of a useEffect hook like this guy did.

Not only next, but also react is boring me this days.

​@@WebDevCodySvelteKit is phenomenal. I feel like all I do is write what I want and almost never fight the framework. Rich Harris also just tweeted a preview of the performance of the upcoming Svelte 5 release and it is really impressive. My biggest gripe with Svelte/SvelteKit is the lack of a mature unstyled UI library. Best I've seen is MeltUI but it's not yet 1.0. There are some decent styled libraries (like Skeleton UI) but they're too opinionated for my taste.
