Overview

If you’re working with large datasets in React and need a way to efficiently handle infinite scrolling, look no further than the react-window-infinite-loader. This library is tailored for use with react-window, offering a streamlined approach to load data on demand. It’s inspired by the functionality of react-virtualized, making it ideal for projects that require high performance and responsiveness.

With the new useInfiniteLoader hook, managing your loading states and data requests has never been easier. Whether you’re dealing with a fixed list or a dynamically changing dataset, this tool can help enhance user experience by loading data seamlessly as users scroll through your lists.

Features

  • Efficient Row Loading: Uses a custom function, isRowLoaded, to track the loaded state of each row, ensuring only what’s necessary is fetched during scrolling.

  • Dynamic Row Count: The rowCount prop allows for an arbitrary high number, perfect for when the exact number of rows is unknown, which provides flexibility in various scenarios.

  • Batch Requests: With the minimumBatchSize option, you can specify the number of rows to load at once (default is 10), helping to optimize data fetching and reduce unnecessary HTTP requests.

  • Pre-fetching: The threshold prop indicates when to start fetching data based on the user’s scroll position, allowing data to load in anticipation before the user reaches the bottom of the list.

  • Render Prop Function: Provides a render prop for more customized control over the rendering of items, enhancing the extensibility of your lists.

  • Promise-based Loading: The loadMoreRows callback returns a Promise that resolves once the data is fully loaded, integrating seamlessly with asynchronous operations in React.

  • Simplicity and Flexibility: This library is easy to integrate, making it a suitable choice for both beginners and seasoned developers looking to implement infinite scrolling.
