MDN’s new design is in Beta! A sneak peek:


The integrity read-only property of the Request interface contains the subresource integrity value of the request.


var myIntegrity = request.integrity;


The subresource integrity value of the request (e.g., sha256-BpfBw7ivV8q2jLiT13fxDYAe2tJllusRSZ273h2nFSE=).

If an integrity has not been specified, the property returns ''.


In the following snippet, we create a new request using the Request.Request() constructor (for an image file in the same directory as the script), then save the request integrity value in a variable:

var myRequest = new Request('flowers.jpg');
var myIntegrity = myRequest.integrity;
