The Images binding is for doing transformations in code

WWalshy yeah that isn't valid functions code

CS176•2/25/25, 11:19 AM

Ahh thank you

@Walshy | Workers/Pages your always there for my stupid questions

11984 Ford Laser The Images binding is for doing transformations in code

Silvan•2/25/25, 11:35 AM

i figured but when they said image bindings i was expecting the entire service
like https://developers.cloudflare.com/images/upload-images/upload-file-worker/

Cloudflare Docs

Upload via a Worker · Cloudflare Images docs

You can use a Worker to upload your image to Cloudflare Images.

SSilvan i figured but when they said image bindings i was expecting the entire service ...

1984 Ford LaserOP•2/25/25, 11:37 AM

Usually they're expecting that the images will be stored somewhere outside Images itself, to be transformed by the binding. I would like your suggestion to be added, as well as listing and getting images directly through the binding instead of needing to pull from R2 or similar

Silvan•2/25/25, 11:39 AM

yea i will have to do things like that soon still have to decide if images alone can even do what i want. else its just r2

1984 Ford LaserOP•2/25/25, 11:58 AM

so the Images binding allows a maximum of 10 transforms per call (

"IMAGES_TRANSFORM_ERROR 9432: Bad request: 10 \"transforms\" maximum"

"IMAGES_TRANSFORM_ERROR 9432: Bad request: 10 \"transforms\" maximum"

). In the docs there is this note for error 9432:

 The Images Binding is not available using legacy billing. Your account is using the legacy Image Resizing subscription. To bind Images to your Worker, you will need to update your plan to the Images subscription in the dashboard.

Is this an error or just part of the runtime?
Edit: I pay for the 'Images Stream Basic' subscription

Hi, i have a question about the rules and R2, I have a rule that redirects all traffic on my domain. But i want to setup a custom domain for R2 storage and i want that the traffic on this domain is not redirecting, but showing the content. Will this custom domain thing overwrite the CloudFlare Rule?

Hi. I use this a lot when debugging my Pages function - npx wrangler pages deployment tail --environment "preview". But, it often just closes the connection and exits after it spits out a few debugging statements. Is there some type of timeout that I need to configure to keep it listening until I'm done debugging?

MEAT SHIELD•2/25/25, 6:50 PM

hi. when I set environment variables they are not available to my pages deployment. see "Environment variables: none". what am I doing wrong?

matt•2/25/25, 11:25 PM

in a pages function, can I connect to a cloudflare tunnel if there are no public dns records?

matt•2/25/25, 11:49 PM

looks like you need either a dns record or a load balancer, since dns records are public... can i use a load balancer and route to the tunnel if the incoming request contains a header secret?

Peps•2/26/25, 2:18 AM

you could totally do that. I forgot if the free plan has access to WAF, but if it does, you could simply create a WAF rule that blocks all requests to that specific subdomain when it doesn't contain a specific header with a pre-determined value

Peps•2/26/25, 2:19 AM

another option would be using Cloudflare Access and making use of a service token to programmatically access the protected app (which would mean just setting 2 headers basically)
https://developers.cloudflare.com/cloudflare-one/identity/service-tokens/

matt•2/26/25, 2:26 AM

cheers @Peps

I ended up just using a load balancer rule since I already had one in place to route between my Pages app and some backend routes on my k8s service that users need to access. i just added the extra condition to the custom rule and voilà!

although the secret does come through in plaintext in the UI, I will probably need to switch to your method if im looking for something more secure

matt•2/26/25, 4:05 AM

how do you create a secret for the Preview branch from the CLI?

TetraEtc•2/26/25, 4:18 AM

page, or worker?

TetraEtc•2/26/25, 4:22 AM

I believe, just

wrangler pages secret put <key> <value> --environment preview

wrangler pages secret put <key> <value> --environment preview

matt•2/26/25, 4:39 AM

for Pages... but I've been through all the help screens and there's nothing to switch environments

bunx wrangler pages secret list --environment preview
✘ [ERROR] Unknown argument: environment

bunx wrangler pages secret list --environment preview
✘ [ERROR] Unknown argument: environment

matt•2/26/25, 4:39 AM

oh its

that works! but not documented in any

1984 Ford LaserOP•2/26/25, 10:31 AM

Can the Images docs get a Limits page documenting things like this?

wolfmankey•2/26/25, 11:53 AM

Hey! Im running a worker that fetches a cloudflare page(static HTML with static assets JS/CSS) and serves it back to the user if a URL-pattern matches.

It seems all the static assets are served totally uncached on each page load. The worker is set to only run on the "/" path, but turned off on "/static-assets".

Do we need to specifically add cache headers for each type, or can this be handled automagically by the CF Page or worker?

Silvan•2/26/25, 11:56 AM

Does anyone have a nice way to debug/log latency?
i use workers assets + d1. locally my api and server routes take 20-40ms while in prod its 70-150 and it feels kind of high? d1 reports queries taking less than 1ms.

Are recipes kinda dead?
Were they replaced with something else perhaps, or maybe I'm looking in the wrong places?
The recipe-exchange official CF forum is ... dead
every "awesome" list I can find for workers is quite outdated
etc

basically looking to browse stuff that I could very quickly just slap on a worker

~~facing something similar as well. after deployment, the query takes quite some time even though the db has practically less data and the query is a single where clause for auth~~
i checked and it looks like a kv issue for me https://imgur.com/a/XSoQP7Q

Hey, I have a hono worker, and I want to call another hono worker via service bindings
Can we do something like this?

Keebs•2/26/25, 8:37 PM

whats the best way to send emails via a pages function right now?

Keebs•2/26/25, 8:37 PM

if I dont want to use some third part, can I use the worker type email somehow?

Silvan•2/26/25, 9:12 PM

should i worry about this? i currently just do pnpm run build and pnpm wrangler deploy

KKeebs if I dont want to use some third part, can I use the worker type email somehow?

Ashley•2/26/25, 10:27 PM

You can’t send emails without using a third-party provider I’m arraid

Luiz Carvalho•2/26/25, 11:14 PM

Is there any way to do this via API or CLI?

Go to Workers & Pages > Create application > Pages > Connect to Git and create a new Pages project.

AAshley You can’t send emails without using a third-party provider I’m arraid

Keebs•2/26/25, 11:16 PM

i thought with the email offering there might be a way now?

Keebs•2/26/25, 11:16 PM

or its just receiving?

Cyb3r-Jak3•2/26/25, 11:16 PM

Yes with the API https://developers.cloudflare.com/api/resources/pages/

Cloudflare API | Pages

Interact with Cloudflare's products and services via the Cloudflare API

KKeebs i thought with the email offering there might be a way now?

Ashley•2/26/25, 11:20 PM

There’s Email Workers, but they can only receive mail - technically you can reply to an email once (but not threads of emails) and you can’t just send a random email e.g. account welcome, password reset etc

Keebs•2/26/25, 11:21 PM

ah alright

Keebs•2/26/25, 11:21 PM

going to use resend i guess, looks simple enough for what i want to do

Keebs•2/26/25, 11:22 PM

thanks for the answer @Ashley :)

HHard@Work No, since they run under your `workers.dev`, which has Cache disabled

dave•2/27/25, 5:00 PM

And to confirm, even the Cache API doesn't work?

Ddave And to confirm, even the Cache API doesn't work?

Hard@Work•2/27/25, 5:02 PM

IIRC, it will work in that it won't error, it will just never store/return cached values

AngryUkr•2/27/25, 5:40 PM

hey all, not sure what's the best place to post a question to avoid spam

could someone please assist with this one workers-and-pages-helpAPO works incorrectly when routing worker is active

Walshy•2/27/25, 7:32 PM

UAM or Purge would not help - let me take a look

Walshy•2/27/25, 7:32 PM

this should only ever happen for like new sites until there's a first deploy

Walshy•2/27/25, 7:32 PM

what's the pages.devpages.dev backing this?
