How to use it

Export the ReactPrefetchProvider and wrap your app in it. This allows us to use the useReactPrefetch from anywhere on our site.

import { ReactPrefetchProvider } from "react-fast-prefetch";

<ReactPrefetchProvider>
  <YourApp />
</ReactPrefetchProvider>;

Import the useReactPrefetch hook into a component where your href link is located. Destructure the prefetch function from the hook, and call it onMouseEnter or onMouseDown depending on the priorty of your link. Applying to many onMouseEnter prefetches could cause memory issues, so it's recommended to only use onMouseEnter on very high traffic links.

import { useReactPrefetch } from "react-fast-prefetch";

const Home = () => {
  const { prefetch } = useReactPrefetch();

  const prefetchData = () => {
    prefetch("https://jsonplaceholder.typicode.com/todos/1");
  };

  return <Link onMouseEnter={prefetchData} to="/about"></Link>;
};

In your component that that needs data, destructure fetchData from the hook, and use it like you would with axios.

import { useReactPrefetch } from "react-fast-prefetch"

const About = () => {
const { fetchData } = useReactPrefetch()

    useEffect(() => {
        fetchData('https://jsonplaceholder.typicode.com/todos/1').then(response =>
            // USE THE RESPONSE FROM FETCH HERE
        );
    },  [])

    return (
        <Link onMouseEnter={prefetchData}></Link>
    )

}
