Functions is just Workers in a Pages project

Hello, I’m Allie!•11/4/23, 4:23 PM

So either way is good

baboonOP•11/4/23, 4:23 PM

I mean I am gonna use pages to host the static page and assets anyway, so I guess then functions it is.

baboonOP•11/4/23, 4:24 PM

I read it uses more CPU though, will it be much slower?

baboonOP•11/4/23, 4:24 PM

Can pages functions handle some serious concurrent requests?

Bbaboon I read it uses more CPU though, will it be much slower?

Hello, I’m Allie!•11/4/23, 4:24 PM

They should use the same CPU

baboonOP•11/4/23, 4:25 PM

Why do these 2 exists at the same time?

baboonOP•11/4/23, 4:25 PM

Clearly there is some significat difference for different use cases

Bbaboon Why do these 2 exists at the same time?

Hello, I’m Allie!•11/4/23, 4:25 PM

They are merging them slowly

baboonOP•11/4/23, 4:26 PM

Do you know anything about that?

Hello, I’m Allie!•11/4/23, 4:26 PM

Functions works with Pages, and Workers get the newest features

Hello, I’m Allie!•11/4/23, 4:26 PM

That's the main difference

baboonOP•11/4/23, 4:26 PM

thanks alot

baboonOP•11/4/23, 4:27 PM

do you recommend the worker AI over gpt for just summarazing and generating?

baboonOP•11/4/23, 4:28 PM

oh sh * it that is off topic, apologies

Chaika•11/6/23, 3:11 PM

It would get cancelled yea. You can use waitUntil with the promise which will let the promise run without blocking the response: https://developers.cloudflare.com/workers/runtime-apis/handlers/fetch/#contextwaituntil

Fetch Handler · Cloudflare Workers docs

Incoming HTTP requests to a Worker are passed to the fetch() handler as a request object. To respond to the request with a response, return a Response …

AAntol Is there a way to use waitUntil with the staticFormsPlugin?

Chaika•11/6/23, 3:14 PM

doesn't look like it, no, you don't get passed context, maybe some way to hack it but I'm not too familiar with Pages Plugins, but it lets you return either a Response or a Promise<Response>. If you're doing anything like submitting the data, you should really await it so the user knows the form request really did go through

Chaika•11/6/23, 10:25 PM

You might want to reconsider mailchannels: workers-and-pages-discussions
Regardless, it needs to be your pages.dev (even if using a custom domain, has to be the pages.dev of your project), it corresponds with the cf-worker header. ex: cfid=myproject.pages.dev

Jeremy•11/6/23, 10:29 PM

Ah, figured. I don't think any of that is relevant if we have lockdown/SPF/DKIM though, right?

Hi, looking for some help with functions to help me fetch json data from a third party API.

Apologies in advanced if I have got this all wrong, I am usually just front-end but I am helping this animal rescue organisation make their webpage - and to list the animals they have for adoption we are using a third party api that needs a API secret. To hide the API secret from the client-end I went about making an express.js backend that will be hosted and the end points will simply just call the
third party API with the secret, and some basic filtering queries will just be appeneded to the fetch.

As this is just a simple 'backend' I believe it would be best suited for serverless functions like on Cloudflare Pages Functions as I have migrated the static page to be hosted on Cloudflare Pages already. Would this implementation be possible in CloudFlare Pages functions. I tried looking through documentation and attempted to implement last night, would the basic functions act the same with a getRequest. I had issues with parsing the request for the queries as well as returning a proper response. An example query would be ".../listings?page=1&species=Cat"

If anyone has any examples they could point me to or any guidance I would greatly appreciate it.

Attached is an example endpoint for the express implementation.

Any plans to not bundle all functions into one worker and have a worker per function file? I understood that this is the case, but just learned recently that it is not. I really wish it would be a worker per function :/

kian•11/8/23, 5:50 PM

Not that I'm aware of - Workers (and Pages frameworks) projects become a single bundled Worker.

alex (he/him)•11/8/23, 7:17 PM

Yes, but it would be great if that could change in the future.

alex (he/him)•11/8/23, 7:17 PM

You can also use Functions plugins, without having to rewrite them to match whatever system your framework uses

Hello, I’m Allie!•11/8/23, 7:39 PM

But yeah, from the perspective of a Framework author, I would generally go with a

_worker.js

Is this to get around size limits, or just to solidify the limits per file?

Multiple reasons, size limits, custom config per page/route, separate api endpoints & frontend pages, better analytics, etc.

I do actually have an idea for how that could work, but it might make Pages more expensive

goldenhelix•11/9/23, 6:12 AM

I am using pages functions where my frontend react app (made with pages) talks to the server side in the functions. Although, this is working, but it is throwing the following message.

"Your worker created multiple branches of a single stream (for instance, by calling response.clone()response.clone() or request.clone()request.clone()) but did not read the body of both branches. This is wasteful, as it forces the system to buffer the entire stream of data in memory, rather than streaming it through. This may cause your worker to be unexpectedly terminated for going over the memory limit. If you only meant to copy the request or response headers and metadata (e.g. in order to be able to modify them), use the appropriate constructors instead (for instance, new Response(response.body, response)new Response(response.body, response), new Request(request)new Request(request), etc)."

I am not calling response.clone()response.clone() or request.clone()request.clone(). Can someone please explain what needs to be done in this case?

getting this error when trying to establish a logging session for a pages function on a preview deployment

TorontoPhysics•11/10/23, 2:05 PM

X-Forwarded-For gets appending when using functions:
I have a simple function attached to my page that runs fetch(). I use the request.headers.get("CF-Connecting-IP") to get the IP of the original requestor and get the 'X-Forwarded-For' header to that IP address. However, when the request goes out, the header is:
X-Forwarded-For: User-Ip, Cloudflare-IP

Where the IP of (I think) CF-Pages gets added to the X-Forwarded. This seems like odd behavior. While technically I believe the path is User -> CF Pages -> CF Function -> fetch-Request It seems this isn't really a double proxy with two Forwards as the CF Pages->CF Function I think should be transparent. In any case, is there a way to get a function in CF-Pages make a fetch with just the user's IP in the X-Forwarded-For header? If I don't manually add that header, CF sets the X-Forwarded-For header to just the Cloudfare-IP.
