Not sure if this is what you're looking for, but subresource integrity perhaps? https://hacks.mozilla.org/2015/09/subresource-integrity-in-firefox-43/ https://

  I did see subresource integrity, but I was also curious about last month's string of high profile magecart vulnerabilities, would subresource have saved them there, or is there more to it?

    SRI won't protect you from: * Someone injecting malicious JS code into your checkout page * Non-static JS includes like Google Analytics But it works well for static assets like jQuery or other static JS resources.

      I was working with OP on a static asset integrity tool and testing I found out google analytics and facebook change their code multiple times a day!

        It's been interesting working with teams that have well-defined release management workflows and continuous integration with snapshotted npm/mvn dependencies, but still allow a third party like GA to inject JS that skips the QA queue. Likewise with CloudFlare: Allowing a third party to proxy all your traffic is a huge liability. CloudBleed should have been a wake-up call, but it doesn't seem to have had much effect.
