As of today working with react-query v5 I noticed two changes - 1. If you are importing & calling a function from another file in queryFn it has to be written in a arrow function like queryFn: () => getData() 2. Fetch request is getting called on browser tab change even without mentioning staleTime, and to stop it you need to explicitly mention refetchOnWindowFocus: false Please let me know if others are also facing the same.
i'm new to react and haven't used redux at all, i followed one of your react tutorials and have been using react query since, this video is much appreciated, thanks!
Thanks pedro. Your teaching is awesome. Can you make a video on tanstack react typescript. There are not that much videos on tanstack tables and I’m having lot of errors
I think you is brazilian, right!? I started my channel trying record 100% in english, but the videos got very awkward. I always remember you when I want post a new video.
This is great, hey bro.. can you please make a video regarding react-google-maps? I think if you do the video it could help a lot of people wasting time on alot of tutorials that doesn't teach much.
i dont understand why your code was working and my code not. When you use useQuery for fetching data with id and title i was getting data undefined, after i added isLoading and isError it worked. "In the initial render without isLoading and isError checks, your component tries to map over data, which is undefined, hence causing an error. React doesn't render components with errors, so your component won't be displayed." This was an explication from chatGpt and still dont get it why handling isLoading and isError made the code to work and fetch the data
you can set initial data as empty array, like this const { data = [] } = useQuery….. If you dont want to set initial data then when you are mapping over it have some check like data?.map or data && data.map
I have been following your Reactjs course 2023 and there in the react-query tutorial, you mentioned that the queryFn should return the data fetched by the Fetch API, which then will be stored in the variable. Why are we returning a promise in this case?..considering that the json() method returns a promise.
Did u try it using with next js 14? When I try to use it with next js 14 and create a custom hook that fetches data from the server using tanstack .... the data seem to load properly but the html content does not appear on the page source... note am using the custom hook in a client component...
one request, not about the teaching ,but about the video. Most of the time , in addition to the youtube, viewers, mostly beginners ,also needs to open multiple apps, such as vs code or any code editor, ,browser with multiple tabs, other softwares such as postman etc, so students like me, who has a midrange pc, it would be a slightly heavy load for the device. so in addition to this, if the youtube video itself is also 60fps, it will just double the ram consumption and load to the CPU. Unlike a gaming video which requires 60fps, 1080px @ 30 fps is more than enough for coding videos. so please consider this request in the future videos.

Yeah not everyone knows its the same thing
Seriously haha you need that title
amazing brother ! have been searching for a proper tutorial and found yours
thanks Pedro. I've been looking for a good video guide, just getting started with React query. was so happy when i saw yours.
did you read my mind bro? i was searching for this
How is this even possible? Just Finished your React Query module from react js course and found it bit outdated and here you are.... Just Wow😮
clean and informative . make more good video like this on various topic . eg : (react testing)
this is the best library to be honest, doing it native will take long time!!
i'm new to react and haven't used redux at all, i followed one of your react tutorials and have been using react query since, this video is much appreciated, thanks!
You should make your intro you spinning in a circle while the music plays "Pedro, Pedro, Pedro, Pedro Techhh" 😁
react-query is an amazing library, and great explanation!
I am not native english speaker but some how i can understand you clearly. Maybe your way of teaching is very good
Glad to hear that!!
Thank you so much Pedro. I'm really liking your content about React because you explain very clear in your videos.
wow just what I was looking for, thank u for this amazing video.
React Query + Next.js 14 + prefetch query + using prefetched query in server side nested components ... would be amazing video!
Exactly what I was looking for! Thanks 🎆
Excelente vídeo meu brother. Deu um overview massa.
Great vid. Lots of companies now using this library, very useful.
A very usefull video I learned a lot thanks.
best explanation ever
Great bro, Wallah you are a Master
we need more videos of this kind
We want to see more videos on this. 😍 Thank you
A continuation video using complex searches, passing parameters, and such would be great.
Please make a video about pagination and advanced react query
thanks brother it help me a lot to understand react query♥
Thanks pedro. Your teaching is awesome. Can you make a video on tanstack react typescript. There are not that much videos on tanstack tables and I’m having lot of errors
This was concise and informative. Thanks!
Que vídeo excelente cara! Parabéns!
thank you that was so great 🌺🌺
welcome back pedro , your videos are the best
I think you is brazilian, right!? I started my channel trying record 100% in english, but the videos got very awkward. I always remember you when I want post a new video.
thank you so much for this!
It would be great to see your next video about react-query
it would be cool if you could bring more videos about this topic maybe a project using pagination and infinite scroll as you mentioned
Staletime is a win for me.
This is great, hey bro.. can you please make a video regarding react-google-maps? I think if you do the video it could help a lot of people wasting time on alot of tutorials that doesn't teach much.
Maybe more on dependencies and query Keys?
Awesome content, I might also cover this topic in one of my videos.
I just completed it... loved it
We miss u pedro❤
Thanks for the refresher 👍
16:16 and what is the difference between isLoading and isPending
Fantastic tutorial!
thanks pedro🤜
I really understood it
thanks for the video , can you please share the link of repo....
Hi excellent video :)
Would you make a video how exactly react query can manage globally state ?
Thanks I can now flex to my bosses some React Query stuff
I have been waiting for this
Thanks so much, this was superful. I hope you could work on the pagination also,
also is this proper
{ queryKey: ['word', 'status', 'done'] }
Nicely explained
Very helpful tutorial thank you
what theme do you use? i looks awesome

you can set initial data as empty array, like this const { data = [] } = useQuery…..

I am also getting data undefined error but my code is an exact copy of his???? Thanks for this comment. I was thinking I am losing my mind😂
thanks for the tutorial brother,
ty Pedro, hello from Ukraine 👋
Thank you Perdo
How can we replace redux,zutand with react query
it would be great if you can use typescript with this
Thanks for this. I was wondering what is the benefit of using this library over redux? Because I can do pretty much same using redux and more.
I have been following your Reactjs course 2023 and there in the react-query tutorial, you mentioned that the queryFn should return the data fetched by the Fetch API, which then will be stored in the variable. Why are we returning a promise in this case?..considering that the json() method returns a promise.
make a detailed advance video on react-query please with real backend data
Should I stick to RTK Query when using Redux?
Plzz make a latest firebase tutorial or app write it will be helpful
Did u try it using with next js 14? When I try to use it with next js 14 and create a custom hook that fetches data from the server using tanstack .... the data seem to load properly but the html content does not appear on the page source... note am using the custom hook in a client component...
One question, when we are using for example Axios and want to test it using react testing library we can mock it. How can we test this react-query ?
Awesome, Next time do it with Infinite Scrolling
Amazing tutorial
please make video on infinite and pagination in react query plzzz
Pedro , why you don't try svelte/kit
pedrao, sua opinião sobre a fala do CEO da nvidia?
I wonder, what is the name of the extension which shows size of npm lib
its called import cost
i found out that it doest work with axios
make another one React Query 🎉
Why using CRA and not VITE ? CRA is so slow!
Pedro 😊
can we get the source code bro??
