Unless I'm mistaken, that is the client's closest datacentre, not necessarily where the worker is running if smart placement is enabled?

Chaika•8/4/24, 1:16 AM

If smart placement is enabled then request.cf.colo would indeed just be the entry data center and not the worker is running in. You'd have to fetch /cdn-cgi/trace to get the colo then within the worker or look at the cf-placement response header (which you can't get/see within the worker).
In other cases request.cf.colo would be accurate though and it's way easier then those other options

Brett Willis•8/4/24, 2:32 AM

Would /cdn-cgi/trace/cdn-cgi/trace be against any Cloudflare "orange clouded" hostname?

Chaika•8/4/24, 2:36 AM

You can just fetch https://cloudflare.com/cdn-cgi/tracehttps://cloudflare.com/cdn-cgi/trace

Chaika•8/4/24, 2:37 AM

any proxied/orange cloud hostname would work though yea, although you wouldn't want to depend on something that could change in the future. It's a pretty cheap subrequest as it should be handled by same machine/same location

Brett Willis•8/4/24, 2:37 AM

Ok understood

Barry_Based_Benson•8/4/24, 7:13 PM

What's the correct way to skip a prod worker when the locally-running version of that same worker also needs to access the same route so that it doesn't conflict with the prod worker's code?

Barry_Based_Benson•8/4/24, 7:19 PM

Currently I send a key in a header to skip if the env is prod but it seems a bit messy. Not sure if there's a more official way to do it

I've spotted TraceMetrics while I was working on my tail worker in the typescript types for @clouflare/workers-types@clouflare/workers-types:

export interface TraceMetrics {
  readonly cpuTime: number;
  readonly wallTime: number;
}
export interface UnsafeTraceMetrics {
  fromTrace(item: TraceItem): TraceMetrics;
}

export interface TraceMetrics {
  readonly cpuTime: number;
  readonly wallTime: number;
}
export interface UnsafeTraceMetrics {
  fromTrace(item: TraceItem): TraceMetrics;
}

Is this already available under a flag?

Isaac McFadyen•8/5/24, 2:22 PM

Usually the types marked unsafe are either for internal use only or only in the non-production (i.e. selfhosted) workerdworkerd runtime.

ItsWendell•8/5/24, 2:24 PM

Yeah I already suspected that, I even tried to see if the production global scope of a tail worker had these available but sadly no, would be great to have it available in a tail / trace worker to better debug CPU spikes

Rohan•8/5/24, 2:26 PM

Hey guys im new to cloudflare so bear with me
my question is whether I can run a tensorflow.js program in worker
its basically a model to convert chess images to FEN(notation)
from what i searched the answer is kinda vague

Rohan•8/5/24, 2:27 PM

I dont think it can run in python worker from what i searched since its pure python

Isaac McFadyen•8/5/24, 2:30 PM

That's correct (re Python workers). You might be able to run via Tensorflow.js assuming the combination of runtime and model is light enough - under 10MB combined.

Isaac McFadyen•8/5/24, 2:30 PM

I'm assuming tensorflow.js uses WASM which is supported on Workers with the caveat of the 10MB size limit total.

Rohan•8/5/24, 2:32 PM

Erisa•8/6/24, 5:45 AM

you dont really, I usually add them as comments to the wrangler.toml

Ashley•8/6/24, 8:39 AM

And if they are encrypted because they are genuine secrets though, e.g. API keys, then they shouldn't be kept in plaintext at all and whoever wanted to use/fork your worker would need to add it themselves - if they are not secret and just need to be set in the environment, you can set environment variables
