new Function() on Workers? It turns out a library I'm using relies on it for it's core functionality and I'd rather not reimplement it all

I can see the WebSocket support is gradually improved over the time, as well as mqtt support, I wonder how long will WebSocket connections remain open once connected from client? It is not immediately clear to me by reading: https://developers.cloudflare.com/workers/examples/websockets/

Using the WebSockets API · Cloudflare Workers docs

WebSockets allow you to communicate in real time with your Cloudflare Workers serverless functions. In this guide, you will learn the basics of …

Unsmart•12/21/23, 4:50 PM

It depends how long it takes for you to reach the CPU limits

space77along•12/21/23, 4:50 PM

OK? How do I calculate that?

space77along•12/21/23, 4:51 PM

I'm trying to replace a node-red implementation that receive from mqtt and send to WebSocket connected to that topic at any moment, basically an adapter. No storage is required.

Unsmart•12/21/23, 4:52 PM

There's not really any good way to know your CPU usage unless you are enterprise unfortunately.

space77along•12/21/23, 4:52 PM

We are enterprise, is this something we need to purchase as addon?

Unsmart•12/21/23, 4:55 PM

You can use http logpush and enable the workers cpu time field, that will get you per request cpu time. Havent tested it myself but websockets specifically should show up after it is closed with the full cpu time it took during the entire time it was connected. So you can open up a websocket throw some sample requests you would do and close it. Take note of the cpu used and the duration and use that to see max length of connection possible by the cpu limit you have (30s max and default)

space77along•12/21/23, 4:57 PM

OK thanks, should be cheaper than IBM WebSphere anyway haha.

Hi! I asked this in queue-beta, hope it's ok to ask it here too: When I have a worker that is a queue consumer with a max_batch_size of 5, does this imply that the processing of those 5 messages will share the 128MB memory allocated to the worker? And if I set the max_batch_size to 1, does it ensure that the processing of each message will exclusively have 128MB of memory?

Hi! I have created a worker using the web dashboard, now several developers need to be able to make changes to this project locally, we followed the steps to install wrangler, but we can't find a way to fetch/download this project/worker to make changes to it locally, does anyone know how to do that? thank you

Hello! Does Cloudflare have any existing standards/best practices for creating a back-end API with Workers that can be written in Go? From what I've read, if you want to use Go with Workers, sounds like you'll need to convert it to WebAssembly but having some trouble finding examples of a Worker using Go

If I call an LB endpoint from within a worker, will WAF rate limiting rules apply to that LB endpoint?

liam | helius.dev•12/22/23, 2:13 AM

Or is it skipped because its calling it from within the worker?

Any suggestion on getting plain IP address from the request header?

When I use request.headers.get("CF-Connecting-IP")request.headers.get("CF-Connecting-IP"), in a worker it prints -

"ip": "2a06:98c0:3600::103",

"ip": "2a06:98c0:3600::103",

If a user connects via IPv6 then the connecting IP will be an IPv6 one.

They are 2 entirely different things and you can’t get an IPv4 from IPv6 or vice versa.

Cyb3r-Jak3•12/22/23, 9:11 AM

You’d have to disable IPv6 on your zone to prevent users from connecting via IPv6, but would affect all your other sites. Also think you need pro plan for it.

Chaika•12/22/23, 1:41 PM

As a stopgap to accelerate the adoption of IPv6, Cloudflare offers Pseudo IPv4 which supports IPv6 addresses in legacy applications expecting IPv4 addresses. The goal is to provide a nearly unique IPv4 address for each IPv6 address, using Class E IPv4 address space, which is designated as experimental and would not normally see traffic

It just generates a fake one

HHello, I’m Allie!And afaik, since Workers support IPv6, then that won't do anything anyway

Chaika•12/22/23, 4:28 PM

hmm what do you mean by that? They run behind proxy, you can have V4/V6 only workers ex: https://v4.chaika.me/, https://v6.chaika.me/, have to use Ent Spectrum though.
Free plan can still disable IPv6 last I checked, should make any workers v4 only (on that zone/domain via routes or custom domains). Can't do that for v6 though without Spectrum

Hello, I’m Allie!•12/22/23, 4:31 PM

I meant in that case specifically, since Workers are the "origin"(and they support both), it should still return IPv6

Finally, we made it clear that customers can serve video and other large files using the CDN so long as that content is hosted by a Cloudflare service like Stream, Images, or R2.

Ahh so the blog says this (no mention of DevPlat), but it looks like you're right when you look here:

https://www.cloudflare.com/service-specific-terms-application-services/

Cloudflare offers specific Paid Services (e.g., the Developer Platform, Images, and Stream) that you must use in order to serve video and other large files via the CDN.

Thanks!

One of my function is waiting for a promise to be resolved. Imagine it took 10 seconds for promise to be resolved in which the network call took 9 seconds to fetch the response. In this case, how much I would be billed for?

1. 1000 milliseconds OR
2. 10,000 milliseconds?

kian•12/23/23, 3:21 AM

Bundled? N/A (doesn't charge by duration)
Unbound? 10s (wall time)
Standard? 1s (CPU time)

ashutosh•12/23/23, 3:27 AM

With Standard pricing.

ashutosh•12/23/23, 3:28 AM

I think Bundled and Unbound will be discontinued in the future. Right?
