Edge headers with Workers
export default {
async fetch(req) {
const res = await fetch(req);
const newHeaders = new Headers(res.headers);
newHeaders.set('Link', '; rel=preload; as=style');
return new Response(res.body, { status: res.status, headers: newHeaders });
}
};

- Serve a fast 404 and helpful 410 for removed content.
Measure
- Use PageSpeed Insights and Cloudflare Speed.
- Track CWV in GSC; annotate changes.
