Add integrity hashes for remote scripts and stylesheets#61
Merged
Conversation
Why these changes are being introduced: It's good practice to validate checksums for external libraries. We've done this in individual apps, but it makes sense to make the change in the theme gem. Relevant ticket(s): * [ENGX-290](https://mitlibraries.atlassian.net/browse/ENGX-290) How this addresses that need: This adds `integrity`, `crossorigin`, and `referrerpolicy` attributes for remotely hosted scripts and stylesheets. Side effects of this change: I'm not totally sure how to exhaustively test these changes. I've confirmed that the scripts/stylesheets load as expected, and checked the changes locally in a few of our apps. That feels like enough, but just signaling the uncertainty here in case the reviewer has additional insight.
