Though you don't really "pick" that

Hello, I’m Allie!OP•3/27/24, 8:48 PM

Other than where your origin is

HHello, I’m Allie!Though you don't really "pick" that

Chaika•3/27/24, 8:49 PM

you can kind of hack it by binding it to a d1 and it'll run near the d1 but not perfect

jason•3/27/24, 8:51 PM

I'm writing a worker to measure a website's performance, and I'd like to be able to measure it from multiple spots around the world. Right now I'm proxying requests through some Amazon API Gateways to get the "source" of the request in different parts of the world. But I'd like to be able to only use CF and not have to rely on proxy servers.

jason•3/27/24, 8:55 PM

It looks like attaching to a D1 might be the best choice at the moment.

Chaika•3/27/24, 8:56 PM

for my own monitoring I just have cron going to DOs with location hints in each region

Chaika•3/27/24, 8:56 PM

a bit expensive though since you pay for duration with DOs

Chaika•3/27/24, 8:57 PM

with the d1 hack or DOs, you can only go where DOs go eitherway, which means no South Africa, or South America, or Sydney Australia, China, Russia, etc

Chaika•3/27/24, 8:57 PM

only where DOs run: https://where.durableobjects.live/, and only in coarse region assignments

jason•3/27/24, 8:57 PM

Okay, so probably just sticking with my proxy servers then.

You pass it in, or use

AsyncLocalStorage

AsyncLocalStorage

Cloudflare Docs

AsyncLocalStorage · Cloudflare Workers docs

To use Node.js APIs in your Worker, add the nodejs_compat compatibility flag to your wrangler.toml file.

Hello, I’m Allie!OP•3/28/24, 9:40 AM

Yeah, so like

   // use env here
}

export default {
  async fetch(req, env) {
    myNewFunction(env);
    // Do more stuff
  }
}

   // use env here
}

export default {
  async fetch(req, env) {
    myNewFunction(env);

}

Hali•3/28/24, 9:44 AM

ah, I see. So now we can use

env.variable_name

env.variable_name

, right?

HHali ah, I see. So now we can use `env.variable_name`, right?

Hello, I’m Allie!OP•3/28/24, 9:44 AM

Yup

Hali•3/28/24, 9:45 AM

Gotcha, I'll give it a try. Thank you so much!

HHello, I’m Allie!Yup

Hali•3/28/24, 9:53 AM

Sorry, could you mind showing me how to use AsyncLocalStorage as I feel like this would be more convenient? I have some variables stored in cloudflare variables. How could I get them? Thank you!

ItsWendell•3/28/24, 10:25 AM

I think the part where you assign domain names to a worker has disappeared from the Cloudflare Dashboard, should be at: https://dash.cloudflare.com/XXXX/workers/services/view/WORKERNAME/production/triggers right? But it's gone? Any tips on how to bind (sub)-domains to workers now?

Hi! How can we setup llangchain or something siimilar on cloudflare

@Chaika have you had issues with query encoding on Backblaze B2 before?

Ddave @Chaika have you had issues with query encoding on Backblaze B2 before?

dave•3/28/24, 2:27 PM

I can't use

in the

response-cache-control

response-cache-control

query parameter on Backblaze B2. It works fine on R2 though. I'm using aws4fetch for signing.

dave•3/28/24, 2:30 PM

oh, manually replacing

with

%3D

%3D

on the signed URL works

dave•3/28/24, 2:30 PM

weird.

Ddave @Chaika have you had issues with query encoding on Backblaze B2 before?

Chaika•3/28/24, 2:33 PM

I've only ever used b2 with rclone before, and I don't actively use it atm

dave•3/28/24, 2:54 PM

ty, I moved my question to general-discussions since it's not a Worker question anymore

Isaac McFadyen•3/28/24, 4:04 PM

Once your cron handler is finished then the Worker will be idle, yes.

Isaac McFadyen•3/28/24, 4:04 PM

Workers only run when invoked, either from a request (fetch handler) or a cron (scheduled handler).

Isaac McFadyen•3/28/24, 4:04 PM

If you need something to run all the time then you should probably look at non-serverless options, Workers don't really suit that use-case

Chaika•3/28/24, 7:58 PM

Not a known issue I know of then. I've got a few for requests that always seemed fine.
Might be service binding requests or something, the dash often filters/shows requests in a specific way via graphql

Hello CF community! I have a project where I'm using react with Pages, and I would like to use Supabase Auth, and I have some questions. Tbh, I don't know from where to start (beginner alert

). The integration of Workers include Supabase Auth? If so, should I use it in my project to auth users, or I can just stick to the client-side from react? Also, is there anyone who tried and made this work who eventually has some repo as a reference? Thanks a lot in advance.

zach•3/29/24, 4:36 AM

I think it'd be easier to stick with clientside

zach•3/29/24, 4:37 AM

with a worker in the middle, you gotta handle frontend <-> worker <-> supa errors

zach•3/29/24, 4:37 AM

i think if you have properly scoped access tokens for supa, you'll be chill to use it on the clientside

zach•3/29/24, 4:38 AM

that said, I've never been happy with letting untrusted internet interface directly with my db

Alvee•3/29/24, 4:43 AM

does cloudflare loadbalacner have concurrent connectino limits ?

vimo•3/29/24, 11:23 AM

Is there a way to pause the quick reload of the workers playground? or add a delay to its reload?

K•3/29/24, 11:54 AM

There is an issues with concurrent fetches and queing. Its described and posted with workaround here workers-and-pages-helpSimultaneous fetches over 6 are being dropped instead of being queued.

I don't know whom to ping for this (which channel) so I'll leave it here.
