02/22/2023, 7:16 PMif I'm adding an unsub header at the top, is this the sane way to do it?Copy codetypescript class ElementHandler { element(element: Element) { console.log(`Incoming element: ${element.tagName}`); element.prepend("<p>Unsubscribe</p>", {html: true}); } } const rewriter = new HTMLRewriter().on('body', new ElementHandler()) const amp_content_value_rewritten = await rewriter.transform(new Response(amp_content.value.toString())); console.debug(await amp_content_value_rewritten.text()); - p
