When applications fail to manage large amounts of data effectively, they perform poorly.
Pagination and infinite scrolling are two popular techniques it’s possible for you to use to optimize app performance.
They can help you handle data rendering more efficiently and enhance the overall user experience.
In contrast, infinite scrolling provides a more dynamic browsing experience.
As the user scrolls, new data loads and displays automatically, eliminating the need for explicit navigation.
Pagination and infinite scrolling aim to efficiently manage and present large amounts of data.
The choice between the two depends on the tool’s data requirements.

Setting Up a Next.js Project
To get started, create a Next.js project.
Install thelatest version of Next.js 13 which uses the App directory.
Next, implement the TanStack package in your project usingnpm, the Node package manager.
To do that, importQueryClientandQueryClientProviderfrom TanStack Query.
Implement Pagination Using the useQuery Hook
TheuseQueryhook streamlines data fetching and management.
With these features, you’re free to effortlessly create a seamless pagination experience.
Now, to implement pagination in the Next.js app, create aPagination/page.jsfile in thesrc/appdirectory.
Inside this file, make the following imports:
Then, define a React functional component.
In this case, use theJSONPlaceholder APIto fetch a set of posts.
Lastly, thequeryFnparameter,fetchPosts, triggers the function call to fetch data.
These states includeisLoading, isError, and more.
This code also serves two other functions:
Lastly, start the development server.
Then, head over tohttp://localhost:3000/Paginationin a internet tool.
Infinite Scrolling Using the useInfiniteQuery Hook
Infinite scrolling provides a seamless browsing experience.
A good example is YouTube, which fetches new videos automatically and displays them as you scroll down.
To implement infinite scrolling, add anInfiniteScroll/page.jsfile in thesrc/appdirectory.
Then, make the following imports:
Next, create a React functional component.
Now, define the useInfiniteQuery hook.
When the component initially mounts, the hook will fetch the first page of data from the server.
This allows you to easily map over and render the individual posts.
Lastly, include the JSX elements for the posts that render in the surfing app.
once you nail made all the changes, visithttp://localhost:3000/InfiniteScrollto see them in action.
Simply put, it’s an all-around data management library.
