rel=modulepreload

The modulepreload keyword, for the rel attribute of the <link> element, provides a declarative way to preemptively fetch a module script and its dependencies, and store them in the document's module map for later evaluation.

The type of the preloaded module may also be set to "script" using the as attribute (as="script"), though this is not required as it is the default.
