quicklink – Prefetch links (during idle time) based on what is in the user’s viewport

Great little piece of JavaScript which prefetches links, but only when the browser is idle (and when the user is on a “fast” connection). Uses the aforementioned Intersection Observer to detect which links are in-view.

Install it per NPM and call its quicklink(); method – for example after the DOM has loaded – to initialize the script.

Amongst ignore patterns, it’s also possible to define the origins which are allowed to be preloaded.
