API

Vue.addPreLink(link, elementRef)

Preload single resource. You can provide type ('image'|'script'|'font'|'etc') and a elementRef ('preload'|'prefetch')

Vue.preloadGroup(resourceMap)

Preload group of resources of multiple types. The map keys are limited to valid preload asset types: script, style, image, media, document, font. Also, you can define if is a preload or a prefetch.

Other details

This library adds an id using vue-link-pre${hash} of the url to preload, to avoid duplicating the element in the DOM.
