In this scrolling condition, at the bottom we by mistake sending multiple requests. So you can replace that logic with this, This will call our function only one time:
useEffect(() => {
window.addEventListener("scroll", handleScroll);
return () => window.removeEventListener("scroll", handleScroll);
}, []);
const handleScroll = () => {
const { scrollTop, clientHeight, scrollHeight } =
document.documentElement;
if (scrollTop + clientHeight >= scrollHeight) {
setPage((prev) => prev + 1);
}
};

[@francoagustin765]

Good tutorial, I haven't seen one like it. others had a lot of logic that when applying it I forgot everything. One thing that I would need is to verify that it does not look for more data if there is no next page.

[@CodeBlessYou]

For that you need to get total number of posts from your backend and after that you can do - ( totalPosts/postsPerPage ) This will return total number of page and then in codition, you have to put page

[@rezafirouzabadi176]

when the scroll is in subcontainer of whole window, and if we want implement scroll in that container will this work?

[@CodeBlessYou]

For that you have to track scroll for that container

[@immanuelrajmohan830]

thank u bruh very short and simple

[@CodeBlessYou]

You're welcome!

[@athulgeorge4873]

Great Tutorial, just wondering if we were to use a our own rest api, would we limit and offset to get the next data be ideal? Also how do we keep the loading animation for longer, setting the loading state to false within a setTimeout is not working for me.

[@CodeBlessYou]

Check setTimeout function if there are some error

[@roycechriston5389]

can you make the like facebook remove recent videos,post, when keep scrolling

We can create that, but for that we need to change in the backend. Because the data we want to show, i coming from backend.

Thank very useful. question, why do not you use a Intersection Observer API? when shold we use eventListener or Intersection Observer API?

[@CodeBlessYou]

You can use both for infinite scrolling. This is the easy way to do that

[@keerthanamalisetty7487]

It would help if u show us how to do this with backend also with nodejs and mongodb

[@pelumioye4196]

hey man, wonderful tutorial but what do i do if i'm using my own server/backend and not a link that has "per_page and page=" ?

[@CodeBlessYou]

Then you have to create API which send posts by page number. When user reach to bottom of page, then you have to call API for that.

[@growwithdesign]

I have my own API file created in my react project, where I am manually maintaining records. How to use your own API file instead of using an external url?

[@CodeBlessYou]

Sorry I don't have clear understanding about that

[@charankumarbasam5866]

Good video.

[@CodeBlessYou]

Thanks😃

[@jritzeku]

Any examples with Redux ? Also isn''t it bad to be making multiple network requests as you are here every 500ms?

[@CodeBlessYou]

I find that in this scrolling condition, at the bottom we by mistake sending multiple requests. So you can replace this logic with this, This will call our function only one time:
useEffect(() => {
window.addEventListener("scroll", handleScroll);
return () => window.removeEventListener("scroll", handleScroll);
}, []);
const handleScroll = () => {
const { scrollTop, clientHeight, scrollHeight } =
document.documentElement;
if (scrollTop + clientHeight >= scrollHeight) {
setPage((prev) => prev + 1);
}
};

[@mylow_____]

yeeeeessssss

[@anikbarua5483]

Suppose i have my own json data that doesn't come from any api so how to add page number in this data?

[@CodeBlessYou]

In that case, you have to set two variables: currentPage=1 and postsPerPage=8,
Now when you reach to bottom, then currentPage will 2 and you have to skip (currentPage - 1)*postsPerPage which is 8, so you have to skip 8 posts from your json data.
If your currentPage is 3 then you have to skip first 16 posts from your json data.
If you already have data offline in your application, then you don't need to add pagination or infinite scrolling. They are just for reducing the data load to server.

[@sandhyaginare857]

Can we do the same if we are getting the data from dummy json file?????

[@CodeBlessYou]

In that case, we don't want Infinite scrolling, we can simply display the data. Because Infinite scrolling essentially for reducing load to server for not sending 100posts in one request.

[@charankumarbasam5866]

make a video on intersection observer

[@CodeBlessYou]

Sure😀

[@AdityaSharan811]

U cannot make callback inside useEffect as async !!

[@CodeBlessYou]

Yes, You can declare async function outside of the useEffects and then call that function in useEffect

[@anjalii1102]

are you gujarati

[@CodeBlessYou]

Yes😄😄 Did you notice that? You are good observer
