DHow does Worker Queue placement work?
Dif you use an email provider like AWS SES in your Email Worker, you can set up SES to publish events to SNS and have SNS fanout events via HTTPS endpoints to another Worker.
FHello everyone, I just received an alert that I reached 100k limit of Workers requests per day, is there a way to see separately each Workers amount of requests?
CUnder the Workers & Pages Tab, for each Worker it should show you the requests in the last 24 hours, and you can click to see even more metrics under the metrics tab of the worker
CFor Pages you have to click in and go to Functions Metrics
JOh wait.. I can't send transactional emails to my users in an email worker without "verifying" the addresses?
CWith the Send Email Binding that is correct
Cit's not meant that kind of use case, since you have to verify each address
This is useful for when you want to know about certain types of events being triggered, for example.https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/
JThat's a shame, was hoping I'd be able to migrate another thing to cloudflare
FThank you for your answer, it's weird, I received that I reached 100k but when I check Worker by worker, each pages functions they are all in the 10th requests. Over all it should be less than 200. What am I missing?
JOh right, more for kind of internal stuff
Cyea hopefully you found that out before you tried hooking up stuff to it.
Email sending is a hard thing to do right, lots of spam filters and such

CDo you see your request quota in the top right of the Workers & pages page, telling you how much you've used?
JOh yeah, haven't started playing with it. Just not liking the idea of giving MailChimp another $20 a month
FI feel like there is something wrong happening, when I wrote my first message it was at 30k, now it's at 93k, in few minutes 
FI just refreshed and it's. What is happening ?!
?!
Cit's slow to update/eventually consistent
Cprobably just catching up
Cstill means you got a lot of requests in a small period of time
FI don't get it, where I check each workers, they have almost no requests, where are all these requests coming from?
CFor 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?
