react-virtualized VS react-lazyload

You may increase the rendering efficiency of tabular and huge list data by using the React Virtualized module. React apps perform better overall when the quantity of requests and DOM elements is limited. React Virtualized is comparable to many other tools; however, what sets it apart from the competition is the sheer volume of features and excellent upkeep.

If you have been using React for awhile, you may have heard of the infamous virtualisation library react-window or it's predecessor react-virtualized

React Virtualized is a React library that helps you work with large lists and tabular data efficiently in React. It has more than 25K stars on GitHub and more than 2.5 million weekly downloads on NPM as of August 2023.

Use virtualization (e.g. react-virtualized) to prevent off-screen components from actually rendering.

Virtualization can be achieved using third-party libraries like react-window or react-virtualized. These libraries provide a way to render only the visible data and load more data as needed, resulting in faster application performance.

You can implement the same pattern on the web when dealing with large amount of data. There are some libraries for React that trivialize this, like https://github.com/bvaughn/react-virtualized

Oh, right. I totally forgot to mention that– but the idea of "less rendering" in this case seems less like a Suspense concern and more like a windowing concern. I've written a few libraries for that stuff (react-window and react-virtualized) although there are others that may fit your needs better. Their main focus is limiting what you're rendering to more or less only what's on the screen at any given point. Combine that with memoized filtering and I would imagine you're set.

I've used the InfiniteLoader from react-virtualized in combination with useInfiniteQuery from @tanstack/react-query and it was relatively painless.

Here’s a react library https://github.com/bvaughn/react-virtualized

In this situation, lazy loading, a popular technique used to defer the loading of resources until needed, can be implemented to defer rendering a component unless the user scrolls down to bring it into the viewport. One of the most popular lazy loading libraries in React, react-lazyload, makes use of conditional rendering to render components only when they are scrolled into the viewport of the user's browser or, in other words, are visible to the user.

React LazyLoad is a library specifically built for that purpose. You just wrap your component, and this library takes care of the rest.

React-lazyload :

I'd you are using a frontend framework, you can use lazy loading that loads more content on scroll. For Vue: https://github.com/hilongjw/vue-lazyload For React: https://github.com/twobin/react-lazyload

Also, consider using react-lazyload or react-window or next.js dynamic import to handle your excessive dom size.
