React-virtualized

Standalone version of the AutoSizer component from react-virtualized, react-virtualized. Some components like those found in react-window or react-virtualized require numeric width and height parameters, react-virtualized. The AutoSizer component can be useful if you want to react-virtualized percentage based dimensions. Flex containers don't prevent their children from growing and AutoSizer greedily grows to fill as much space as possible.

A common requirement in web applications is displaying lists of data. Or tables with headers and scrolls. You have probably done it hundreds of times. And what if the pagination technique is not an option or maybe it is but you still have to show a lot of information? The infinite scrolling technique only limits rendering future elements and renders all previous rows, causing performance issues for very large lists.

Interested in our next book? In this guide, we will discuss list virtualization also known as windowing. This is the idea of rendering only visible rows of content in a dynamic list instead of the entire list. The rows rendered are only a small subset of the full list with what is visible the window moving as the user scrolls. This can improve rendering performance. If you use React and need to display large lists of data efficiently , you may be familiar with react-virtualized. A video walkthrough of list virtualization with react-window accompanies this write-up. Windowing in react-virtualized works by:. Rather than rendering s of elements from a list at once which can cause slower initial rendering or impact scroll performance , virtualization focuses on rendering just items visible to the user. This can help keep list rendering fast on mid to low-end devices. In a tree-shakeable library, size is a function of which API surfaces you choose to use. The APIs for both packages are similar and where they differ, react-window tends to be simpler. Lists render a windowed list row of elements meaning that only the visible rows are displayed to users e.

If you're considering adding react-virtualized to a project, take a look at react-window as a possible lighter-weight alternative. Learn more about how the two libraries compare here. Note webpack 4 makes this optimization itself, see the documentation.

React itself aims to decrease the number of times we directly interact with the DOM. In this article, we will compare react-window and react-virtualize, as they are similar but offer different levels of support and overhead to your project. List virtualization, or windowing, is a technique for improving the performance of rendering long lists by only writing the visible portion of the list to the DOM. This works by having a small window element moving over a bigger container, which will host the items, but will only render the items that are currently visible to the user through that window. A few other items in the list, which are outside the limits of the window but are close to the upper and lower boundaries, might be rendered so that when they enter into the view, they will already be loaded into the page.

Note: there are some caveats to the approach in the demo above as there are caveats to using the actual CellMeasurer in react-virtualized. Interested in our next book? Try to create a simple photo collection with this component. This a good example of how core components from react-window can be easily combined to achieve complex scenarios that react-virtualized would solve with one component. This is an advanced property and is not typically necessary. I actively welcome pull requests; learn how to contribute.
