I was wondering, would it be possible to make a worker respond to Websockets o SSE events?
As in, keeping a long running connection, and reacting to incomming messages.

I know that workers currently have no limit on wall time, only limiting cpu time, and the worker would be idle while waiting for events..
But i have no idea on how one would "bind" that, if it was possilbe

My usecase is that i have a provider that emmits cdc events using a SSE endpoint, that constantly sends out the events, and i want to capture and process them with CF

I have a huge issue. A worker route is not working. Its in worker routes, the domain is attached to the worker. But when I look, I don't see the worker in the dns records... :/

Hello guys, i've been trying to setup two integrations for my worker, sentry & baselime. But turns out, the wizard overwrote the previous tail worker.
Does it make sense to any of you to write a tail worker to push to 1 queue per integration, ie: sentry-queue baselime-queue and write consumers to push in batch to each service?

removed the domain and added it back to the worker fixed it... hopefully this doesn't happen again :/

Are these notifications still a thing? https://blog.cloudflare.com/introducing-workers-usage-notifications/ I see them on my account, but not receiving the emails, and "test" button doesn't send anything. Just wondering if there's a good way to keep tabs on increased CPU usage for a worker than handles a huge number of requests (where a change from 1ms to 5ms could see a big jump in billing).

I need help and realy fast

jjjrmy•10/10/24, 3:54 PM

if I wanted to constantly listen to a websocket and save that data to KV, would that be a worker or no? Basically it would always be listening to stock market data.

not sure if a worker should be long living like that or not.

SameerOP•10/10/24, 5:25 PM

my nextjs worker build is like 16791.80KiB

SameerOP•10/10/24, 5:25 PM

Hello guys, does anyone know how to change a worker's environment variables through the API? Which endpoint should I use? It would be even better if there are examples.:MeowHeartCloudflare:

Leo_C•10/11/24, 8:29 AM

Yes, I have tried, but I only want to update a variable without replacing the entire worker, which is too unsafe.:NotLikeThis:

Never tried WebSockets with Workers, but any reason not to use Durable Objects? As they have built-in handling for WebSockets, and will be a lot more cost-effective than a Worker as they can hibernate while not processing messages

Ashley•10/11/24, 6:12 PM

I’d take a look at Durable Objects in that case - Workers are perfect for HTTP, but Durable Objects are designed to handle WebSockets, so a lot better fit

Flare•10/12/24, 3:44 PM

When your domain is proxied by Cloudflare, it is assigned an IP address from a shared pool in the Cloudflare network. As discussed in more detail in the below-linked blog post, a government or ISP's decision to block one of those IP addresses is likely to have unintended and disproportionate effects on non-targeted sites.

Those disproportionate effects are typically inconsistent with legal requirements. If you believe your site to be unintentionally blocked by an ISP, it is recommended that you reach out directly to the ISP of the affected users to ensure they are aware of the collateral consequences of the block so that it can be addressed.

Please do still report any incidents to Cloudflare, as Cloudflare is working on initiatives to bring attention to and help address incidents of overblocking. You can report this on https://community.cloudflare.com/ with the tag #ISPBlock.

I neeed some help

Hasi•10/13/24, 1:15 PM

my Workers (paid) are getting cancelled

Hasi•10/13/24, 1:15 PM

why?

Hasi•10/13/24, 1:19 PM

better question

Hasi•10/13/24, 1:19 PM

how to prevent cancellation when the worker need s to send 2 requests

Peps•10/13/24, 6:33 PM

what do you mean with cancelled?

Peps•10/13/24, 6:34 PM

the requests your worker is doing are being called?

Peps•10/13/24, 6:35 PM

if so use to keep your fetch calls alive after your worker has sent a response

Having trouble with typescript class constructor shortcuts, like

looks like they don't get assigned. x is always undefined. Known limitation?

Constantin•10/14/24, 1:13 AM

howdy, trying to assign workers to a wildcard domain like

[env.main.route]
zone_id = "fedc08dd76405e8f83259f8cf9e77f3d"
pattern = "*.app.greatoutdoors.live"
custom_domain = true

however this is not working

Chaika•10/14/24, 2:13 AM

Yea, Worker Routes can be wildcard but not Custom Domains. Additionally you'd need a certificate covering

masd4•10/14/24, 8:53 AM

Is there just the single .dev.vars file for all environments? It would be nice if I could have a config per environment that doesnt go into wrangler.toml because that gets checked in

Constantin•10/14/24, 9:37 AM

thanks Chaika, works fine. for some reason i was expecting to see them in the dns zone (but when used only as patterns, they don't show up)

Constantin•10/14/24, 9:39 AM

ie there a good guide tu setup custom domains for a sass app. i already have a worker in between, that adds an x-served-for header. but i'm missing the big picture .. the TXT validation and what CF API i should be calling
