destination property
The destination read-only
property of the Request interface returns a string
describing the type of content being requested.
The string must be one of the audio, audioworklet,
document, embed, fencedframe, font, frame,
iframe, image, json, manifest, object,
paintworklet, report, script, sharedworker,
style, track, video, worker
or xslt strings, or the empty string, which is the default value.
The destination is used by the to, for example,
help determine which set of rules to follow for CORS purposes, or how to
navigate any
complicated code paths that affect how specific types of request get
handled.
These destinations vary substantially in how they operate. Some are data
receptacles,
where the received data is stored for processing later. Others are
script-based, in
which case the received data is delivered to a script by calling it and
passing the data
along. Script-based destinations include script elements, as well as
any of the Worklet-based destinations
(including subclasses like AudioWorklet), and the
Worker-based destinations, including ServiceWorker
and SharedWorker.
