if i send something properly, this is how it looks like

but postman could be doing some stuff that doesn't show me if it fails CORS

The thing is, i get a 401 thrown from the browser as it should, but above it gives me that CORS error

Are you replying with JSON?

ye, stringified

Check your JSON, that error would be because it's invalid/formatted incorrectly.

True, if its actually wrong creds, then its not json, should fix that

Alright, no more cors errors, thanks

@Isaac McFadyen | YYZ01 Pinging you just because we were discussing it yesterday, and a small update in case anyone else wants to utilize the cloudflare cdn in front of their pages application for dynamic pages/functions. If you put a worker in front of the pages project and use that to handle every request to it, you can use the

cacheEverything

& `cacheTtl `https://developers.cloudflare.com/workers/runtime-apis/request/#requestinitcfproperties properties to store the results of that request in the cdn, rather than worker cache. (So cache status shows MISS/HIT instead of dynamic) Pros Can utilize cdn tiered cache to get more cache hits Reduced load on external downstream systems (db/external apis) Save costs if a function has a long runtime Can invalidate cdn globally using the api, compared to the worker cache where you can only create/delete from the workers cache in the data centre the request is being run in. Cons Not worth doing if your page is lightweight Lose control of cdn/cache duration on function level, this is controlled at the worker level now (eg even if function has cache-control private, it will be cached if the worker sets it to be cached) The function can't return headers that would store it in cache, as it will go to the workers cache as well. So you need to know before sending the request to the function whether the result should be cached (eg path, presence of a header/cookie etc) You'll always run a worker for every request, there's no way to have the CDN in front of the worker which could be done if you used an external origin (tradeoff which imo is worth it due to how cheap workers are). More complicated CORS/host setup.

~~I have a pages sveltkit deployment e.g. newcoolpage.pages.dev I'm hoping to use pages to incrementally replace an existing site's paths with pages-based versions. e.g. my-current-site.com/oldcoolpage is replaced with newcoolpage.pages.dev I can't seem to add a path-based url as a custom domain for a pages, so I set up a worker (e.g newcoolpage-proxy.workers.dev) and added my-current-site.com/oldcoolpage as a trigger and it simply responds with a fetch of newcoolpage.pages.dev. If it hit the default worker's trigger the whole thing works beautifully but if I browse to the custom trigger I evenutally get a 522 Time Out from cloudflare... any ideas??? Worker logs actually don't even show hits when calling the proxied url my-current-site.com/oldcoolpage, but I do get logs hitting the default worker trigger.~~ I figured it out... I was using *.my-current-site.com/oldcoolpage... e.g. the preceeding dot was the issue.

is it possible to add headers after middleware next()?

Yeah.. should be possible indeed. If I remember correctly the return value of next() is a Response right?

yeah, i was adding a header but it was null, now i realized it's probably an error from my end

We are trying to build a function to invoke Direct Creator Upload but are getting a CORS error, any tips on how did it? We don't have any issues with it on Workers

I can't seem to access the public folder in a Functions-project; is this a design decision, or did I perhaps do something wrong? can't seem to access

{HOST}/favicon.ico

or

{BASE_DOMAIN}/public/favicon.ico

or

{BASE_DOMAIN}/static/favicon.ico

.
├── functions
│   └── [[path]].ts
└── public
    ├── favicon.ico

How are you trying to access them?

not through some API, just browsing through Firefox

I believe you need to explicitly return the static asset from your Function using

context.next()

(which gets the associated static asset for the request)

ohhhh, I see thanks! the assets need to be stored on Workers KV, right? so I'd need some kind of build step as well, I assuem

Because your Function is a catch-all it's intercepting everything.

And no, if you are using Pages it'll automatically store the static asset.

Just make sure your build output directory is set to

public

if you want to access things in

public

thanks, @Isaac McFadyen | YYZ01 it was the catch all pretty neat, I love functions! very simple layout

I'm trying to use the

PagesFunction

type from @ cloudflare/workers-types in my function, but I'm not sure how to use it correctly? There doesn't appear to be a way to type an entire function

Not Cloudflare 😆

(sorry that did not mean to ping)

Unsure if I'm using it wrong or not

I think it might go after the )?
