i'd prefer react-query + trpc or react-query+server-actions(yes it's possible). I love react query. because it's reduces state management complexity and usage of useEffect , also caching and handling loading states are so easy.

If you write proper next13+ code, you don't need any state management, or useEffects in 95% of cases. Just manage state with urls. Also next does caching really well and on the server side, which is usually preferable.

surprised its not clickbait and actually teaching. thanks for the info

Good video. I still think it depends on the use case. Let's say you're building a sports betting site, and your page needs to be live fed (normally through polling). ReactQuery (or traditional client side fetching) is your best option. RQ also refetches when you go away and come back to the site which is harder to do with Nextjs as you physically need to revalidate the route. So I think this is a great solution for when you have content that may or may not change and you don't want to make it strictly static but you'll no doubt encounter scenarios where tradicional client side requests are of good use. Regardless, well explained, was very informative!

What a great video bro. Making things clear and understanable

Great content!! new insight achieved, thank you !

High quality video, thanks!

really appreciate these indepth videos

A tutorial on how to apply correct caching in a nextjs project would be very helpful. I struggle with that a lot which page should be static and which one should be dynamic, when to use the no_store() in queries and when to not use it, etc. Your videos are really helpful, Thanks!

Very good video, keep up the great work! I faced this dilemma when starting my latest project, in which I intended to use RSCs. I was constantly going back and forth between Server Actions and tRPC. Ultimately I stuck with tRPC and I think there are still valid reasons to use it: 1. Built-in validation with Zod 2. Simple integration with React-Hook-Form 3. Using it in Next 14 pretty much disables full route caching of UI and of API requests by default, which is exactly how Next should behave in my opinion. That aggressive level of caching should be opt-in 4. You import one object and get access to all route definitions 5. We still get optional caching in client components 6. You can expose your API to other clients. Of course you can achieve all of those things with Server Components too. Actually they even provide even more, as you can cache full API routes, which may be useful. However, it seemed like implementing them on the level that I require would simply be inconvenient, at least in their current state. If some wrapper for Zod comes in with support for typed FormData, then I think it’ll be the good time to switch

A very good summary. I'd add to that - server actions must always be functions and cannot be grouped or namespaced, meaning you can't really organize them properly and have to resort to weird naming patterns to avoid naming conflicts.

You describe everything so clearly and include caveats as well, which is so helpful. I am new to NextJS and am seeing the benefits of Server Components. Thanks for the great video.

the best nextjs vids! thanks so much for this man

Thanks for the insights. In my experience, like you said, there’re always edge cases that require trpc, but the moment I implement a trpc call to fetch the same object, I have to duplicate the code from my server component’s fetch call (input validation, prisma call, etc). Also having both server calls and trpc makes things hard to find, so I always end up implementing everything in trpc.

really cool! nextjs fetching is just missing a devtools equivalent for easy debugging

Thank you so much for your greate content ♥ I have one question please, what do you think about using GraphQl instead of prisma ORM ?

@juancarlostremolss3158

You can even say it adds an additional layer of security within your app. Most of the time you will not work with devs specialized on Next JS and by providing an extra layer like TRPC, on top of the current benefits, you protect your application from accidentally calling server only functions in the client. TRPC is not mandatory, you can always add a parser between your functions, or follow the NextJS best practices, but a well set up TRPC project actually enforces the good practices

amazing! Thanks :)

BTW what to pass to a Suspense key if it should get an array or object? To check if it has been changed?

9:32 we have a separate backend and I set up code generation that generates fetch functions with the correct types from the same openapi spec that generates the backend routes and types. It's quite a nice way to work. I'm not a huge fan of having nextjs do things like interact with the db etc, that's much easier to structure and test in a dedicated backend (we use nestjs).

@@user-lk3iq2bv7t if you mean it should be the same thing as a dedicated backend, in my opinion it really isn't for larger more complex projects. App router is great, and server actions are awesome, but I prefer to use them to complement dedicated backend(s). For small apps where I just wanted to do a little crud or hit some external third party APIs I wouldn't also spin up my own backend and would just rely on app router though. Many things have tried to claim you can do away with dedicated backends (firebase, lambda, etc) for large projects, but they haven't done it yet.

Ok but how do you disable caching with nextjs? What if I DONT want to cache things. Maybe its something that updates a lot

How do you await fetch in a client component? Can you just make an async client component?

Do you mean V14 of next js and app router? I find the need for react-query using v12, quite a bit.

Great tutorial! However, it would be helpful if you could also cover how to invalidate the cache in Next.js. In software development, it's crucial to remember that overfetching is often preferable to underfetching for better application performance and user experience.

react query is also cached, along with the paths. And on client you can have dynamic data, optimistic updates, etc so in a web app you'd still want to use it. On a site for sure not

Next provides a way to revalidate. If you're using fetch() there's an additional attribute `next` inside where you can add {revalidate: time} Eg: fetch(...., next: { revalidate: 10 // revalidates in 10secs } )

I've been toying with a similar setup, and here's my $.02: Lots of overhead when compared to a server action. The main benefit of using a separate backend is that it's not coupled so tightly to the next app. That is useful if your project ever needs a different consumer, either a different app, public API, or Mobile app.

Can someone tell me how server actions work? A HTTP request is still made to the backend, right?

This is just if you’re using server functions, yes? So if I’m still on Nextjs 13, I should stick with React Query?

I came in as a skeptic but you convinced me to give it a try

how would you combine nextjs with a .net backend api?

if you refresh the page, it will request again right? then the concept would be same like using state management like zustand then? just need to avoid useless render page and store data temporarily on zustand?

Is there another way for handling fetching on the server side without using fetch? as its syntax is well, not my favorite.

You mentioned that server actions are like POST but can't server actions do a GET too?

Will there be another video? ... Why use SvelteKit? :D

When working on a very large project, React Query is still necessary because in large applications, data fetching isn't typically handled directly within components. Instead, server actions are utilized. Additionally, Next.js does not cache API calls made within server actions, at least not as far as I know. If I'm mistaken, please feel free to correct me

I love the idea of server actions, especially to make database requests etc. But if I have a database with personal data, I need to protect the server action from being called. That is why I am frustrated at the moment. I am using server actions for such database queries. However, whatever I do, I cannot protect the server function from being accessed from anyone from the client side. The function is in a folder utils alongside app. The can use it from client side but so can anyone! I have looked everywhere, but I cannot seem to find how to handle that…

18:08 You mention how we can use clients outside of Next.js with tRPC. Could you still use tRPC endpoints on a Swift app for example though? I mean if I used Next.js API routes then I can definitely use that but I'm not sure about using tRPC outside the same project. I believe this is possible within a monorepo/Turborepo if you have a Next.js app with tRPC endpoints/procedures, and then a React Native app could consume those tRPC endpoints/procedures.

@Lucas-gt8en

You can use the tRPC API endpoints just like you would use any other API routes. However tRPC has its own conventions (instead of RESTful and/or OpenAPI conventions) on how to call functions and what format is returned. I’d probably prefer either using React Native if that’s workable in your context or abstract out the data retrieval logic from the API logic so you can create a dedicated RESTful API for mobile with API routes. For the first option I’d look into T3 Turbo as a (very good) starting point. You could also look into tRPC OpenAPI or perhaps there’s a codegen plugin for Swift. I’d shy away from the first option because the tRPC conventions are still there and it is therefore not very readable for non-tRPC users. Also in my experience the user app will deviate from the web API sooner rather than later so building out a separate API while being able to reuse a large parts of the shared data retrieval and business logic feels like a worthwhile investment even when it might not directly pay for itself in the short term.

@Disorrder

3 ай бұрын

tRPC is the same HTTP backend, there is no problem to use it from any client that can parse http and json. You just need to understand request and response formats and have a library for that. But it works seamlessly on any typescript environments. If you're using another language on client, you'd prolly better to use REST or graphQL API

fantastic

give a tutorial video of this project, i really like the user interface of it and would like to explore how you build this application each component part looking very neat.

I don't understand why using type unknown is better than specifying the typeam I because in the server action, you verify the schema and the data type. What I am not seeing well at this?

Within a server component, what do you use when calling anything other than fetch to an http endpoint? Does the server side data-cache only work for fetch calls? What tool or method would you use to make a direct sql call to get the information you need for a server component?

@EduarteBDO

What the server caches is the jsx component that it's returned. Not the fetch call, it caches the data that is used in the jsx boiler plate. So you can use any orm, not just prisma. There are others orm that allow direct sql call.

thanks. now i know server action. i never used it before.

i got into problem with just using server components and server actions, everything was fine until I had to do error handling. instead of just fetching an error amd showing them, I'd probably have to wrap the components with error boundary and lose the custom error handling mechanism for each components or page withiut having to spam error boundary on every componebets. Or am I doing it wrong ? Another problem I got was having an onClick handler in a component and I cannot make it a server component anymore. I could try with URL modifications but that was not a page and was a component, so soon I had to use useEffect or react query alternatives anyway. And its not the issue, the issue is now trying to mimick similar loading and error state as you did with error boundaries. It just became a headache to me. This example is probably an easier ones and works best I agree, but when you go one level complex and complex again, it just starts to be a headache imo. Then on top of that try modals with app router and error handling or routing and data cache invalidations with server actions (invalidating a client component fetchers) does anyone have any experience or bootstrap modal of these on how to model these and create the best structure to handle them?

The t3 stack make all this perfect.

I agree. tRPC+react-query can live on RSC. Only when to invalidate is using "router.refresh()", not "await utils.dotdotdot.invalidate()"

Kinda reminds me of what Meteor was! But more up to date/standards

The downsides you listed are the same reasons we moved away from this format in PHP, Rails, and so many others. Server Side Actions are acceptable if you are only ever going to use your data in that one web app. But why not spend more time creating an API layer that will unlock future growth? Separation of concerns and all that? What happened to mobile-first design principles? This isn't just UI media breakpoints. It is designing sites that can work well with limited or even no connection. In this example, a job site, I sure would want to be able to browse and save jobs on my phone.

Okay, what if i have very huge amount of data? Is ISR still can be solution? I think next js caching good for only static data, good for landing page data but not for dashboard apps where you have more than 2000 page data. It becomes a joke to make 2000 pages on build time. So, unfortunately, we still must use client side caching like react query or redux

The server side won't be able to access the client side local storage I don't think, so you'll likely need to either pass whatever data you need from local storage back to next, or better implement some storage that the server can access also (i.e. cookies). If you're only interested in Auth state and are using oauth then next-auth might be ok, I implemented http only cookies myself and just had any client components make a call to get any locally required info.

Why not fix the cache?

I wouldn't say caching is the sole reason someone would use React-Query for. It also abstracts common necessary variables like isLoading and Error, which needing to handle that in comparison to a hook that already does that for you with the bonus that it has caching, I don't see a reason why someone would not use it just because NextJS has caching. Unless it would conflict with NextJS caching, but would it?

🔥🔥🔥

I see that react query is useful in react native projects.

After watching this i appreciate how good laravel is now nextjs is following that methodology

Raact Query is useful beyonf fetching data. It's allbout about asynchronous operations on the State.

Does there exist a proper implementation of infinite scroll data without using react query prefetching in Next.js server components?

@CouchProgrammer

3 ай бұрын

This is part of the streaming api. It's still experimental. But this is not so important, the important thing is that you want to track the state on the client and initiate a request from the client, which means you must manage the cache and state of requests on the client. This means that you are using React-Query. This means that you have 2 managed caching layers. No options. For static sites, you almost never need to track requests and states; the maximum network interactivity on such sites is a link or a static form, apparently the author makes only such sites.

@CouchProgrammer

3 ай бұрын

Moreover, for static sites like a blog, you want to compile the html and put it on a CDN, that is, you do not need a running application per request. You need to make a couple of endpoints for lambda functions or even connect it as an external service without your own backend. So server actions will eat your money by forcing you to use expensive infrastructure. So for many applications this is a very difficult architectural choice.

Comment unrelated. I love this comment so much which I ready earlier in some other video. Someone made this comment which was going in my mind too, he said "I believe 100% whatever this guy says" and I cannot agree enough 🤣 I believe in Wesley supremacy 🛐

I enjoyed watching this video but chasing the latest shiny thing is not sustainable. If you want to cache calls, just set the appropriate header. If you want to return more records in one call, implement paging. I believe a better approach is to use the platform and learn the concepts, instead of installing yet another dependency and refactoring a whole project. As for server side rendering, I don't imagine it'll ever be competitive as an enterprise solution. We've been there and tried that.

I love redux-toolkit ❤

While I completely agree that NextJS tools have come a long way, there are still many things that it can't do better than these tools. For a simple dashboard, obviously framework native tools easier and cleaner, but when your product needs cache invalidation or route groups requiring API tokens, React Query and tRPC does it better. There isn't a feeling more daunting than realizing that your janky custom workarounds are standard in a package that simplifies your workflow.

Does this work outside of Vercel though?

No way, Vercel team is completely vendor lockin customers through sponsoring such developers to use more and more next js dependencies. Its a game that everyone western software company plays.

The best approach there will still be using client-side async state managers like SWR/React-Query/etc. With initial server-side loading using RSC we update client-side cache and operate with it.

Yeah you don't need the OG, the only robust data fetching solution, the REACT-QUERY 🔥.. As long as you are not making a Todo app 😂😂😂. React query will stay relevant and no.1 as long as it is about async state management.
