# useBufferedFeeds with concurrency

Pass several feed configurations to buffer them in the background. There is no public concurrency-limit option; choose how many feeds your app preloads.

```jsx
import { useBufferedFeeds } from "@bitsocial/bitsocial-react-hooks";

// Replace these names with the communities your app uses.
const feedsOptions = [
  { communities: [{ name: "news.eth" }, { name: "crypto.eth" }], sortType: "new" },
  { communities: [{ name: "memes.eth" }], sortType: "topWeek" },
];

function FeedPreloader() {
  useBufferedFeeds({ feedsOptions });
  return null;
}
```
