![]() ![]() ![]() The preload function can also have any name as it's a pattern, not an API.How to Print Your Own Pattern Block TemplatesĪfter months of looking for pattern block picture cards, I downloaded set 1 off of Kelly’s Kindergarten (found via this blog post – thank you, Sandra!) With this approach, you don't have to pass promises down as props. You can optionally create a preload function to further optimize parallel data fetching. Preloading DataĪnother way to prevent waterfalls is to use the preload pattern. To improve the user experience, you can add a Suspense Boundary to break up the rendering work and show part of the result as soon as possible. If you have nested components, and each component fetches its own data, then data fetching will happen sequentially if those data requests are different (this doesn't apply to requests for the same data as they are automatically memoized).įor example, the Playlists component will only start fetching data once the Artist component has finished fetching data because Playlists depends on the artistID prop: ![]() This reduces client-server waterfalls and the total time it takes to load data.
