Prefetcher

Customize prefetching by combining multiple interactions.

import React, {Fragment} from 'react';
import Prefetcher from 'react-prefetcher';

export default () => (
  <Fragment>
    <Prefetcher
      onRenderAssets="https://example.com/on-render-asset-url"
      onHoverAssets="https://example.com/on-hover-asset-url"
      onClickAssets="https://example.com/on-click-asset-url"
    >
      <p>
        1. Prefetches https://example.com/on-render-asset-url on render of this `<p />` tag.
        2. Prefetches https://example.com/on-hover-asset-url when the user hovers this `<p />` tag.
        3. Prefetches https://example.com/on-click-asset-url when the user clicks this `<p />` tag.
      </p>
    </Prefetcher>
  </Fragment>
);

Possible values for assets

1. URL
2. Array of URLs
3. Object with custom fetcher

URL as asset:

<Prefetcher onRenderAssets="https://example.com/on-render-asset-url" />

Array of URLs:

<Prefetcher
  onRenderAssets={[
    'https://example.com/url',
    'https://example.com/another-url',
  ]}
/>

Custom fetcher function:

<Prefetcher
  onRenderAssets={{
    href: 'an URL or id to prevent redundant fetch',
    fetcher: () => {
      /*custom fetcher that gets invoked on render*/
    },
  }}
/>
