Re: @sjehuda:

Thanks for the visit however this can be achieved outside of the library in post-op before it is applied to the website.

This is also very beta still and very much on the back burner.

Closing as not planned.

I want to know how.
My attempts appear not to work.

Solved by:

function setNonceUponCSP() {
  window.addEventListener("securitypolicyviolation", (e) => {
    //let message = e.originalPolicy;
    //messageTruncated = message.substring(message.indexOf("'nonce-") + 7);
    //let nonceValue = messageTruncated.substring(0, messageTruncated.indexOf("'"));
    let nonceValue = e.originalPolicy.match(/'nonce-(.*?)'/)[1];
    cssStylesheet = document.getElementById(namespace);
    cssStylesheet.setAttribute('nonce', nonceValue);
  }, { passive : true, });
}

I didn't find a way to make it to work on first error.
