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
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.
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 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.
