nextjs infinite scrolling in typescript

To implement infinite scrolling in Next.js with TypeScript, follow these steps:

1. Install the required dependencies: yarn add react-infinite-scroll-component

2. Import the InfiniteScroll component in your file:

index.ts
import InfiniteScroll from 'react-infinite-scroll-component';
62 chars
2 lines

3. Create a state variable to track the page number:

index.ts
const [page, setPage] = useState(1);
37 chars
2 lines

4. Create a function that fetches the next set of data when the user scrolls to the bottom of the page:

index.ts
const fetchNextPage = async () => {
  const res = await fetch(`https://api.example.com/data?page=${page + 1}`);
  const data = await res.json();
  // TODO: Append the new data to your existing data
  setPage(page + 1);
};

7 lines

5. Wrap your list component with the InfiniteScroll component and pass the fetchNextPage function as a prop:

index.ts
<InfiniteScroll
  dataLength={data.length}
  next={fetchNextPage}
  loader={<h4>Loading...</h4>}
  hasMore={true}
>
  {/* TODO: Render your list items here */}
</InfiniteScroll>

9 lines

The dataLength prop is used to determine when to trigger the next function. The loader prop is used to display a loading message while the next set of data is being fetched. The hasMore prop indicates whether there is more data to fetch.

Note: You will need to update the TODO comments with your own code specific to your use case.
