React Query in 40 Minutes - Everything You Need to Know About Tanstack React Query

[@sreerup_dhrino]

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.

This was by far the best video about react query on KZbin. Subscribed for more of this. I love the pace!!!

[@orashusedmund7675]

[@raviel_0422]

Thank you so much Pedro. I'm really liking your content about React because you explain very clear in your videos.

[@anmolkharel4433]

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!

[@tomasburian6550]

Great vid. Lots of companies now using this library, very useful.

[@melkhywong7594]

did you read my mind bro? i was searching for this

[@DjSeymur]

You should make your intro you spinning in a circle while the music plays "Pedro, Pedro, Pedro, Pedro Techhh" 😁

[@singhramneek3358]

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 Just Finished your React Query module from react js course and found it bit outdated and here you are....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😮

[@andrewredican1413]

react-query is an amazing library, and great explanation!

[@jessicajoseph1633]

Amazing content thank you Pedro

[@zalaam_0]

I am not native english speaker but some how i can understand you clearly. Maybe your way of teaching is very good

[@PedroTechnologies]

Glad to hear that!!

[@LyndonBaylinJr]

`onSettled` is the same as the `finally` block in the `try.. catch...`. It will always trigger regardless if its success or failure

[@italofsan]

Excelente vídeo meu brother. Deu um overview massa.

[@lamiaali4519]

wow just what I was looking for, thank u for this amazing video.

[@aseel1024]

this is the best library to be honest, doing it native will take long time!!

[@lopesleticiam]

Exactly what I was looking for! Thanks 🎆

[@codermeloman3030]

React Query + Next.js 14 + prefetch query + using prefetched query in server side nested components ... would be amazing video!

[@onsiteImagitech]

A very usefull video I learned a lot thanks.

[@afamsval]

We want to see more videos on this. 😍 Thank you

[@ramanjaneyuluv479]

[@giovanniferreira1706]

A continuation video using complex searches, passing parameters, and such would be great.

[@vinaykumarkharwar177]

This was concise and informative. Thanks!

[@quentinhall8838]

welcome back pedro , your videos are the best

[@jubert2096]

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

[@АнтонКовалёв-э7к]

It would be great to see your next video about react-query

[@matheuspiegas]

Que vídeo excelente cara! Parabéns!

[@KaranChauhan-fu6dy]

I just completed it... loved it

[@haniehafzali9661]

thank you that was so great 🌺🌺

[@palcherin]

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.

[@bagheldevansh]

thank you so much for this!

[@SuperMBARutgers2013]

Staletime is a win for me.

[@BugArray]

Awesome content, I might also cover this topic in one of my videos.

[@bruningoat]

it would be cool if you could bring more videos about this topic maybe a project using pagination and infinite scroll as you mentioned

[@Developer_BR]

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.

[@k303k]

We miss u pedro❤

[@King_slayer-hd7df]

Thanks for the refresher 👍

[@Goku-zu3rk]

Maybe more on dependencies and query Keys?

[@bobsecondbrain9330]

Fantastic tutorial!

[@sonamohialdin3376]

Very helpful tutorial thank you

[@mihaichildesco8276]

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

[@coderintrovert]

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

[@chippandenga6722]

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😂

[@rajeevbhosle1580]

thanks for the video , can you please share the link of repo....

[@izunduchukwuemika7915]

thanks pedro🤜

[@izunduchukwuemika7915]

I really understood it

[@metalfort1207]

Thanks I can now flex to my bosses some React Query stuff

[@abdulazeezonadipe6236]

Thanks so much, this was superful. I hope you could work on the pagination also, also is this proper { queryKey: ['word', 'status', 'done'] }

[@tiny_mystery]

thanks for the tutorial brother,

[@adi-ai-007]

Nicely explained

[@ValeriiLutiy]

ty Pedro, hello from Ukraine 👋

[@2ameridiem]

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.

[@mehedihassan6904]

make a detailed advance video on react-query please with real backend data

[@dyarydy6939]

Thank you Perdo

[@thebocksters2756]

[@tariqahmed2526]

Plzz make a latest firebase tutorial or app write it will be helpful

[@regilearn2138]

it would be great if you can use typescript with this

[@mjylove2]

what theme do you use? i looks awesome

[@nullwizard6335]

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.

[@mohammadshezan]

Awesome, Next time do it with Infinite Scrolling

[@zainn7336]

please make video on infinite and pagination in react query plzzz

[@waleedsharif618]

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 ?

[@rumonintokyo]

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...

[@niklausmikaelson7332]

How can we replace redux,zutand with react query

[@JOSEPHEZHAP]

[@akshitathakur5722]

Can anyone please help is this react-query V5 ??

[@joeblack8843]

i found out that it doest work with axios

[@IvanGechv]

Why using CRA and not VITE ? CRA is so slow!

[@anburaghu6294]

can we get the source code bro??

[@emmanuelxs6143]

Pedro 😊

[@hooooman.]

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.

[@drippedfilms]

No. 3 - 😂
