Are you saying you have a wildcard on nefele.ai pointing to app.nefele.ai, and thus you expect it to work for

*.app.nefele.ai

*.app.nefele.ai

?
If so, wildcards are a bit fun with DNS. It'll stop if it hits anything, and stop on any deeper labels too. Meaning, your wildcard stops recursing because you have a record created for app.nefele.ai.
You'd have to create another wildcard record for

*.app.nefele.ai

*.app.nefele.ai

That's also too deep for your free Universal certificate which only covers first level subdomains, you'd need Advanced Cert Manager (ACM)

will there ever be a new version of the cloudflare apps? I really though it was a powerfull concept!

piffie•12/18/23, 11:26 PM

Hey guys, we are getting updates from around 4k pricepoints, typically around 30-40 per second.
I first thought about running a worker for this, then maybe to query.
But then i reread the durable object API - and it seems i would best actually handle it inside a durable object to hold the values in memory, and give it from there access to others. Whats the best architecture for that?

Unsmart•12/18/23, 11:27 PM

Youre going to have to explain a bit more about what you are looking for if you want anything useful. With only that limited info no one can suggest anything really.

Hi all

I am wondering about Sentry Tails Worker pricing. Will attaching Sentry mean that I will get all the requests and pricing doubled? Because Tail workers are priced the same as workers and are automatically invoked after the invocation of a producer Worker

While it's possible to get a user's ip country from a worker, is it possible to get the context of where the worker itself is being run? An api I'm quering has different base urls depending on location, ideally I'd wanna call the region closest to the worker when it's being run

Isaac McFadyen•12/19/23, 1:46 PM

The only way is to hit a

/cdn-cgi/trace

/cdn-cgi/trace

endpoint and look for the

colo

colo

field. So for example, https://cloudflare.com/cdn-cgi/trace shows EWR and EWR = New York airport, so Worker is being run in New York.

Isaac McFadyen•12/19/23, 1:47 PM

But also it's probably not necessary. Workers run in every datacenter on the Cloudflare network (350+) which means it will almost always be run close to your user.

Isaac McFadyen•12/19/23, 1:47 PM

So if you use the user's country/region it's almost guaranteed to be near the Worker.

aim was to generate switch cases with string literals to use v8 parse-time optimisations. it's also meant to be readable so i'm not custom rolling any "few"-case minifications into if statements etc and move that to the bundler

Does anyone have a reliable way to track timings inside of a worker? I am aware that

Date.now

Date.now

and

performance.now

are only ever updated when I/O occurs, but how do you guys go about debugging internal latency issues?

For example, if my worker is apparently doing some heavy internal work but you can't find out where, how would you go about that?

juri•12/19/23, 7:00 PM

Would you consider these numbers as "true" then?

juri•12/19/23, 7:01 PM

I think my issue is more about an operation inside of the worker taking longer than expected (parsing data, for example), which is not I/O so

Date.now

Date.now

is never updated.

Kkian Internal as in how does Cloudflare do it, or the community?

juri•12/19/23, 7:02 PM

Oh, internal as in code inside the worker taking a long time to execute — but at the same time not being able to identify what piece of code is responsible because comparing

Date.now

Date.now

inside the worker is not accurate.

kian•12/19/23, 7:04 PM

There isn't really a whole lot you can do. Timing with local development should be accurate, but not in remote development or when published.

juri•12/19/23, 7:06 PM

This will be really hard then, I assume. I unfortunately cannot use the worker locally as it requires being connected to a Dispatch Namespace and D1

DaniFoldi•12/19/23, 7:07 PM

yeah dispatch namespaces don't yet have support in local development, still in an early PR phase meowsad

Unsmart•12/19/23, 7:07 PM

I mean you can always pull out a test where you dont use dispatch namespaces and run it locally to test

DaniFoldi•12/19/23, 7:08 PM

of course you can perform an isolated test to check the timings there, but it's not the best developer experience

kian•12/19/23, 7:11 PM

Yeahhh. Measuring anything latency or CPU/RAM related is a dead end on Workers which sucks as eventually the only billing model is based on CPU runtime that you can only measure on a "whole Worker" basis using the analytics.

kian•12/19/23, 7:18 PM

Well, you can get accurate per-request CPU time if you feel like paying for Enterprise and using LogPush :^)

We should most definitely have access to that, I have not used it before, I'll try out another solution I was proposed and will then check LogPush out!

Unsmart•12/19/23, 7:22 PM

a fetch to a dispatch namespace uses 0ms cpu time so you can figure out where your cpu usage is by taking out specific code blocks and trying to figure out what uses the most cpu there

juri•12/19/23, 7:34 PM

How would you suggest to go about this? Send individual logs to LogPush at the desired spots? The idea is that LogPush then reveals the actual wall-clock times when the logs were pushed, correct?

kian•12/19/23, 7:35 PM

LogPush creates a log per request, you can't send anything to it

kian•12/19/23, 7:36 PM

That log can include

WorkerCPUTime

WorkerCPUTime

and

WorkerWallTimeUs

WorkerWallTimeUs

juri•12/19/23, 7:38 PM

Oh, I see, I also just read that when setting it up. But this is only the total of the request and not individual "checkpoints" I can track during code execution?

kian•12/19/23, 7:39 PM

Correct, total of the request.

juri•12/19/23, 8:41 PM

Is the TimestampMsTimestampMs for every item inside the LogsLogs array wall-clock time or is it based on the same time

performance.now

performance.now

Date.now

Date.now

use?

kian•12/19/23, 8:43 PM

Same as performance/date

kian•12/19/23, 8:43 PM

There is nothing that provides accurate time for individual events in Workers that is available to non-employees.

juri•12/19/23, 10:59 PM

Another idea: could we use Workers Analytics Engine for this? When you call writeDataPointwriteDataPoint, I would expect it to insert data with a correct timestamp.

juri•12/19/23, 11:00 PM

There must be some way to gather metrics inside of a worker reliably.

i am trying to build a sveltekit SSR app that will be deployed to pages. in my app i'm using mongodb. I can't build the project because the workers runtime apparently expects node js apis to be imported with the syntax 'node:crypto'. i have no control over how the mongodb client does its imports. i have no idea how to fix this or proceed.
