For Workers, you can click "sort by Requests" and see if it's any of them

Cfor Pages, would have to click on each one
Dyou can use AWS SES directly from a Cloudflare Worker.
FOkay, so I finally found the source of the problem, I was working on a new worker, and on loading it created this "catastrophe". Just for my own knowledge, why the loading of this workers created this amount of requests?
CYou're saying you purely caused all the requests to it? What does your worker do?
FWell, it turns out I did it 
. I'm trying to implement Stripe, launched the server and it made all these requests... why, I have no idea.
. I'm trying to implement Stripe, launched the server and it made all these requests... why, I have no idea.CStripe itself sending webhooks? Iirc they have pretty good logs you could check
FI wasn't receiving any webhooks, I don't know what error caused this, I was just starting to write the code, launched the server, and this happened. I don't know if some error in my code created a loop of requests.
DIf I do less than 6 concurrent requests, I don't need to await anymore, right?
HYou shouldn’t need to, no
Dthanks, I'm gonna use r2 notifications then to do the mirroring
Dreally stupid quesiton, I have just
export default appoh never mind, I remember, found the code you helped me with for an email worker 
Dwait.. I'm an idiot, I can use R2 S3's CopyObject API call instead!!
Dthere is no need for queues
Bis it me or did api's change for this? i wasnt getting this error before
BWebSockets! (WS) I have a working client and server already communicating nicely using CF doc code as a starting point.
What we want to do is on the server side when changes to data occur broadcast it via WS to all open connections. What I can’t figure out is how to inject these events into the open WS session onmessage eventListener.
Two options I can think of:
1.maintaining a ‘list’ of these events and having a function inside the session handler check it
We didn’t think we could use Socket.io server on the Worker, but couldn’t find anything definitive on this.. but Socket.io natively supports CF on client side via CND bundle https://socket.io/docs/v4/client-installation/#from-a-cdn?
References to code examples supporting this or simply a direction to work towards is appreciated. TIA

- on data changes create a new (another) WS session on the server (using a different Worker?) send the message then close
But these seem excessive for what we believe should be easier.

Sguys please help me to use this in worker , its important
FHi all, does anyone know if it is possible to generate otel logs from a worker? (and send them to an OTEL capable server - we are using Uptrace). Thanks!
SCurious, is it possible at all to use workers to send a webhook after an r2 upload? I use ShareX to upload images to r2, and before when I hosted the images on vultr I had a script that would send a webhook of the image and the link to it to a discord channel, but obviously that isn't possible with r2 itself, so I was wondering if there was a cool lil API I could use with workers to detect an upload and send a webhook :Sips:
MI believe this feature was launched just a couple of days ago -- https://blog.cloudflare.com/r2-events-gcs-migration-infrequent-access
The Cloudflare Blog
We’re excited to announce three new features for Cloudflare R2: event notifications, support for migrations from Google Cloud Storage, and an infrequent access storage tier
SOoo talk about perfect timing
SThank you :salute:
OHi - I just used a new version of Wrangler to create a worker - I'm not sure who thought it was a good idea, but please stop adding things like test and .prettierrc files etc. Not all of us want that stuff - so at the least, add it as options in the init command please.
OThis is fantastic - notifications and long store are much welcomed features!
OSorry - only just saw the wrangler channel - shal post in there

Sis this good way to write in worker to detect bot catagory?
CHey, everyone, I'm Chinese. I saw that CloudFlare Worker can support Python language recently. What does it represent and indicate? Reduced development difficulty and more library and API support? Is there anyone who can analyze it from a professional or non-professional perspective? I don't know much about programming, but I am very interested and happy to learn the information and knowledge it brings.
FIs there a way to make hosting static files in a Cloudflare Worker not consume any requests?
AFAIK, Cloudflare Pages static files have unlimited requests on the free tier, while Cloudflare Worker files take up requests.

FI can't move to Cloudflare Pages because there are some issues with a framework I'm using, so I have to resort to using Cloudflare Workers
HNope, other than having an actual origin, Pages is the way to not pay per request
Fdang.. alright, thanks for the heads up
Dabsolutely love the features in https://blog.cloudflare.com/workers-production-safety !
Gradual rollouts aare a huge thing I've wanted since day #1.

RHello!
I am a bit confused which product would best fit my use case.
Basically, I have a worker acting as a reverse proxy.
The goal is: keep it up to date with the latest config table which is on a remote gcloud database.
What i really want to do is to keep the internal (in memory) config up-to-date across all workers and propagate the remote db changes. What should i use to keep everything running smooth and cost effective with billions requests? I am testing D1 and cron triggers but not sure it's the best approach. Would appreciate some tips --- thanks!

TI am sitting here reading about JavaScript-native RPC in workers...
https://blog.cloudflare.com/javascript-native-rpc
Do I understand this correctly:
I can create a worker, that exports a class extending
This worker kan be added as a binding to other workers, and all the methods will be avaiable.
If I want to create more classes that I want the worker to export, i can create other classes that extend
This way, i can create a whole app, and have it directly accessible from another worker, with no http.
If this EntryPoint worker is updated, it will update on all other workers that has it in its bindings

PHey, how do you unsubscribe from Workers updates?
Ceither <id:customize>, "Which products you u use" uncheck "Workers" or /unsubscribe and pick workers
Pthanks
Bhttps://developers.cloudflare.com/workers/runtime-apis/rpc/ workers rpc is super awesome, are there any plans to bring similar implementations to other languages?
Cloudflare Docs
The built-in, JavaScript-native RPC system built into Workers and Durable Objects.
CIs there a cost associated to using cron triggers? Is it just a single worker request? Anything specific to the cron trigger itself?
Twhat doest this err code mean
Toh nvm
Tsorry for the mess
Chlo all！Does anyone have a GPT program for Worker? Can you send it to me so I can try it out? I'd be very grateful. Thank you!
Tnot sure what you mean
CI mean, has anyone made a mirror of OpenAI ChatGPT using GPT's API and Workers, or made something similar to ChatGPT using CloudFlare's API and Workers? Any information about ChatGPT?
