React InfiniteScroll in a scrollable component on the Page

by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we are going to see how to create a React infinitescroll in a scrollable component on the page with simple steps. Infinite scroll is a mechanism that shows data based on an endless scroll event and loads data only as needed to avoid critical performance issues. Any application, whether it’s a web, desktop, or mobile app, has tons of records in terms of data. A user may want to access this data in one place for any number of reasons related to the product, items, flights, trains, homes, and so on. For such functionality, it is difficult to load all records at once due to overall performance issues, so we need an alternative. One alternative is called an infinite scroll. To complete this task easier, use our ready-made code snippet on kandi with just one click. Copy and paste the code snippet in your IDE.

Code

In this solution we're using React and Infinitescroll libraries.

const DoseListCardBody = () => {
  const [items, setItems] = useState(Array.from({ length: 20 }));

  const fetchMoreData = () => {
    setItems(items.concat(Array.from({ length: 10 })));
  };

  return (
    <div id="scrollableDiv" style={{ height: "100%", overflowY: "scroll" }}>
      <InfiniteScroll
        dataLength={items.length}
        next={fetchMoreData}
        hasMore={items.length < 200}
        loader={<h4>Loading...</h4>}
        scrollableTarget="scrollableDiv"
      >
        {items.map((i, index) => (
          <div style={style} key={index}>
            div - #{index}
          </div>
        ))}
      </InfiniteScroll>
    </div>
  );
};

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Install npm install infinite-scroll.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in app.js file(remove the earlier code from app.js).
Import libraries.
Open the terminal from IDE.
npm start to run the file.
