The require-trusted-types-for and trusted-types directives can be used to enforce the Trusted Types API. This allows you to defend against client-side cross-site scripting (XSS) attacks by mandating that any input must be passed through a transformation function, providing an opportunity to make it safe before it is sent to a web platform API that might otherwise execute it as code.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
