addPrefetchLink
Adds links with rel="prefetch" on user interaction
to speed up page navigation. Loosley inspired by quicklink.
How it works
addPrefetchLink registers a set of EventListeners per link (by default: mouseover and focus) which will then add a prefetch-link to your <head>-element. To avoid unnecessary network requests only one of the events per link will execute that process.
Links won't be added on slow connections or under data saver settings.
Usage
# Installation:
npm i add-prefetch-link// Import library
import { addPrefetchLink } from 'add-prefetch-link';
// Select links
const links = document.querySelectorAll('a:not([href^="mailto:"]):not([href^="tel:"])');
// Call addPrefetchLink on every link
links.forEach((link) => addPrefetchLink(link));
// Use your own set of events
links.forEach((link) => addPrefetchLink(link, ['focus']));Limitations
This package is build with the latest module standard to date so it won't work as an AMD or CommonJS module
