SteffTek•6/18/24, 5:52 PM

be transparent, say the bytes come from the files on your storage backend

NickOP•6/18/24, 5:53 PM

I guess if I get enough $ to afford enterprise then I can offer a “discount” on bandwidth

SteffTek•6/18/24, 5:53 PM

i always tell my business partners: "there are some problems that should be solved with tech solutions, others should be solved with ToS" :D

NickOP•6/18/24, 5:53 PM

Yeah good point! if there’s no easy solution then I’ll go that route, just wondering if I was missing something. Seems not. Thanks anyway

Erisa•6/18/24, 5:58 PM

Yeah for that you wouldnt want to think in terms of bandwidth and rather "bytes retrieved from storage"

SteffTek•6/18/24, 6:03 PM

all your bytes are belong to us

Why am i only getting a CORS error when i try calling worker endpoint from localhost? Works fine calling it in browser and i set Access-Control-Allow-Origin to * as well as added preflight

simons2889•6/19/24, 8:00 AM

At this point, is it possible to communicate via grpc directly from the worker to the client?

Hey all, does someone know if it's possible to use a more advanced http client than the provided

fetch

fetch

? I would like more control on timeouts and ssl which could be done with access to undiciundici or node:httpnode:http but these two don't work on workers

Nicolas•6/19/24, 4:17 PM

The only alternative I see is to wait for Python packages deployment to be available and use httpxhttpx or aiohttpaiohttp, but something in js should surely be available

Chaika•6/19/24, 4:21 PM

fetch goes out through the cdn request pipeline, you'd have to use the tcp socket support https://developers.cloudflare.com/workers/runtime-apis/tcp-sockets/ with some library to do completely arbitrary ssl/timeout stuff. There was work being done on making node networking/sockets work iirc, just slow
fetch() = through cdn, cloudflare.com/ips
TCP Socket = using WARP IPs (unlisted), arbitrary, can't connect to Cloudflare IPs though

Chaika•6/19/24, 4:21 PM

httpx/aiohttp are just patched to normal js fetch https://github.com/cloudflare/workerd/blob/main/src/pyodide/internal/patches/aiohttp.py, would have same limitations with ssl/timeouts

Nesk•6/19/24, 4:45 PM

Hi everyone, is there any way to use the Rate Limiting API with a custom duration period? The documentation says:

Period: the duration of the period, in seconds. Must be either 10 or 60

Is this some kind of limitation during the beta? I would like to use a 1 hour duration period, or more.

Nicolas•6/19/24, 4:50 PM

@Chaika thank you for the details that's interesting

Nesk•6/19/24, 4:57 PM

Yes, as in “yes, you can use a custom period duration”?
Or yes, as in “yes, this is a beta limitation”?

Nesk•6/19/24, 4:58 PM

thank you for your help

cron•6/19/24, 6:36 PM

possibly a silly question - i have a worker that i created 5 months ago and it defaults to a file named index.js for fetch

but i created a worker now, which defaults to worker.js for fetch calls, even if i try to change it to index.js - has something changed with the archetype between the last five months, or did i use a different template while setting up and have forgotten about it?

cron•6/19/24, 6:39 PM

AH. I figured it out - I guess it defaults to wrangler projects now when you're trying to create a blank worker?

cron•6/19/24, 6:39 PM

has it always done that? i feel like i am having amnesia lol

Hard@Work•6/19/24, 7:03 PM

Yeah, I don't think that would be able to be run on any Cloudflare products at the moment. You would need a VPS or something like Fly/AWS Lambda(or another service that can run Node)

madi. ™•6/19/24, 7:03 PM

ah i see, ok thank you :)

Brett Willis•6/19/24, 9:11 PM

Hey, can anyone give a gauge of the hardware performance underpinning the Workers platform? Given that "CPU time" is a billed metric, and we have no gauge of how many ops/sec or something the isolate/thread can do, it is quite arbitrary and hard to gauge. Any hardware acceleration for crypto operations? I'm guessing the hardware is constantly evolving and different depending on the data centre... but perhaps someone can comment or improve my understanding...?

For example, verifying JWTs using the SubtleCrypto API is common on every request for an API, and also a computationally heavy operation. And just from experience I'm getting the feeling that the CPU available to Workers feels pretty slow compared to other "single vCPU" runtimes I've used... any insights?

Ah thanks! I see in https://blog.cloudflare.com/cloudflare-gen-12-server-bigger-better-cooler-in-a-2u1n-form-factor their Gen 11 fleet was AMD Milan 7713, but doesn't look like they actually confirmed what their Gen 12 (2024) fleet is going to be...

Brett Willis•6/19/24, 9:39 PM

Also I've been finding that our Workers get evicted crazy fast. Like it gets evicted in under 5 seconds a lot of the time, and then does a cold start for a request to the same data centre 5 seconds later. Is that normal or what? On a cold start it also has to do a bit of CPU work like importing crypto keys etc.
The docs say that the

env

env

object can be equal by reference until the env variables or bindings change, so we cache our state on the env object but it gets evicted crazy fast.

Brett Willis•6/19/24, 9:42 PM

I've got one too that verifies a JWT and sends a response, and it tends to use upwards of 80ms CPU per request which feels like a lot. But I've got a feeling that a lot of that CPU is related to spinning up a cold environment as it goes down significantly when I ramp up the RPS to keep the instance alive.

Brett Willis•6/19/24, 9:46 PM

Ah I see, that is interesting... It felt natural because the application state is explicitly tied to the env config, and the docs says it's the same object reference between requests. If using global vars I'd have to reason about invalidating when env config changes.
Caching on env does seem to work, but it just seems to get evicted pretty promptly...

Original message was deleted

Brett Willis•6/19/24, 9:46 PM

Are there any docs about this env being a software update that causes eviction?

Brett Willis•6/19/24, 9:52 PM

Hmm ok. Well it's worth a try, I'll try caching on

globalThis

globalThis

instead of

env

env

and let you know if that changes our crazy-fast eviction.

Ttoby357 I'm wondering if this would cache the result from a sub worker

Hello, I’m Allie!•6/20/24, 7:08 AM

Service Bindings are not cached automatically, you need to call the Cache API manually

Database IDs, account IDs, etc. are all safe to publish. The ID is meaningless unless you have access to the account or are a Cloudflare employee. You can see opensource repos published by Cloudflare with IDs in wrangler.toml

MISANTHROPIC J•6/20/24, 6:18 PM

Hi all! Noob here, sorry if this is a silly question, but I'm not finding clear answers. Are workers only able to be deployed on the dev urls created by cloudflare on a free plan ?

Context: I'm trying to set up a reverse proxy worker for dispenseapp so my dispense store url is "mydomain.com/store" the documentation on dispenseapp seems straightforward and even updates code automatically when updating desired store url or adding multiple stores. After setting up everything step by step it works fine on the dev url, but the route pointed at my domain doesn't work at all. I feel like I'm missing a critical step to connect this worker to my domain on cloudflare besides setting up my

route : domain.com/shop*

Zone: domain

Xiao 🥑•6/20/24, 9:14 PM

Hi question about the workers execution time

I'm migrating from Supabase edge function cause they have a hard limit on the function execution time (2 seconds), does anyone know what is the limitation on Workers?
I'm trying to generate a pdf which contains ~30 pages, which could take ~10s.

The issue is I don’t want someone to count the bytes and be like “you’re overcharging me for bandwid
