should have guessed that honestly

S

Senti3ntB3ing•5/7/25, 6:24 PM

thats actually showing up on the page as text/plain (so just the html as written), and if i add the headers

case '/message':
                        let mesRes = {
                            headers:new Headers({ "Content-Type": "text/html" }),
                            body: subHTML
                        }
                        return new Response(mesRes);

case '/message':
                        let mesRes = {
                            headers:new Headers({ "Content-Type": "text/html" }),
                            body: subHTML
                        }
                        return new Response(mesRes);

case '/message':
                        let mesRes = {
                            headers:new Headers({ "Content-Type": "text/html" }),
                            body: subHTML
                        }
                        return new Response(mesRes);

case '/message':
                        let mesRes = {
                            headers:new Headers({ "Content-Type": "text/html" }),
                            body: subHTML
                        }
                        return new Response(mesRes);

S

Senti3ntB3ing•5/7/25, 6:24 PM

it shows up as object Object

W

Walshy•5/7/25, 6:26 PM

https://developer.mozilla.org/en-US/docs/Web/API/Response/Response

first param for Response is the body, you'll want

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

MDN Web Docs

Response: Response() constructor - Web APIs | MDN

The Response() constructor creates a new Response object.

S

Senti3ntB3ing•5/7/25, 6:27 PM

thank you! so trying to form the json myself there, with headers, body, doesn't work because it expects the body first, and then a headers obj after?

W

Walshy•5/7/25, 6:33 PM

yep, body is first param with options as the second (as per mozilla docs)

why does cloudflare remove the

<tbody>

<tbody> element upon serving it?

Senti3ntB3ing•5/7/25, 6:42 PM

i have script on the html file itself that is trying to work on it, but it gets filtered out

Cloudflare has ~275+ locations that run Workers, but most you can do for that is to use Durable Objects and Durable Object Hints, but hints are only to broad regions: https://developers.cloudflare.com/durable-objects/reference/data-location/#supported-locations-1, ~6 of them which are usable

no, much less then that.

Chaika•5/8/25, 4:25 AM

There's 6 Durable Object Regions which actually host Durable Objects (western north america, eastern north america, western europe, eastern europe, asia pacific, and oceania). That's the level of granularity you can spin up Durable Objects in

C

Chaika•5/8/25, 4:26 AM

Each of those regions has ~4-5 locations within which may be picked, and if you're making a new Durable Object instance for each request you'll bounce around between them (or you can reuse your instances to try to stay as sticky as possible to one), but you have no choice over that.
