Shipping support for module script integrity in Chrome & Safari - Shopify

What this post added

Shopify engineers revived Guy Bedford's proposal to integrate integrity metadata into import maps and landed support for subresource integrity in imported module scripts in Chromium and WebKit. This involved creating a working Chromium implementation, updating the HTML spec, and developing a rudimentary test suite. The feature was then implemented in WebKit, leading to its shipping in Chromium 127 (Chrome, Edge) and Safari 18 Beta.
