PBKDF2 is currently limited to 100,000 iterations on Workers, fyi

SSteved @Petter That looks really interesting. A concern of mine is that bcrypt.js on wo...

Unsmart•11/11/23, 8:58 PM

A like 12 or 13 cost bcrypt runs in 500ms and is plenty for the cost value

Kkian PBKDF2 is currently limited to 100,000 iterations on Workers, fyi

Steved•11/11/23, 9:36 PM

Argh. Thanks for the info, that's a pretty good argument against PBKDF2 given OSWAP suggests 600,000+.
And thanks @Unsmart | Tech debt yes, 12 or 13 should be fine, and 500ms seems reasonable.

what's the best way to use fetch with a proxy from a Worker?

sathoro•11/12/23, 6:27 AM

can't find any proxy providers that support a dedicated IP with an API endpoint

bkyerv•11/12/23, 1:20 PM

is there any way to create folders in the dashboard where all workers and pages are listed so to group them by projects?

Cyb3r-Jak3•11/12/23, 3:27 PM

Unfortunately not

bkyerv•11/12/23, 3:56 PM

is this something in the roadmap? I thought this is something that most people would want to use. or am I being biased? now when I heavily use cloudflare for many small projects I spent a lot of time finding my workers and pages.

Theli•11/12/23, 4:31 PM

You are one pages project and few API calls away from it

Ssathoro what's the best way to use fetch with a proxy from a Worker?

dave•11/12/23, 7:34 PM

you mean like a SOCKS-like proxy service that works with Workers?

Ddave you mean like a SOCKS-like proxy service that works with Workers?

sathoro•11/12/23, 7:34 PM

yeah through HTTPS endpoint that has dedicated IP support

sathoro•11/12/23, 7:34 PM

"that has dedicated IP support" this is the part I can't find

sathoro•11/12/23, 7:34 PM

I already have rotating proxies with HTTPS endpoints

Ssathoro "that has dedicated IP support" this is the part I can't find

dave•11/12/23, 7:34 PM

what's the reasoning behind needing a dedicated IP from a third party? Why not use your own?

sathoro•11/12/23, 7:35 PM

my own IP, from where?

Ssathoro I already have rotating proxies with HTTPS endpoints

dave•11/12/23, 7:35 PM

those work with Workers?

sathoro•11/12/23, 7:35 PM

there is a host that has completely blocked all incoming workers

sathoro•11/12/23, 7:35 PM

and we have lots of users that use that host for an integration

sathoro•11/12/23, 7:35 PM

and they won't work with us

Ddave those work with Workers?

sathoro•11/12/23, 7:35 PM

of course because its a normal HTTPS call

sathoro•11/12/23, 7:35 PM

no proxy config

Ssathoro of course because its a normal HTTPS call

dave•11/12/23, 7:36 PM

huh interesting, could you show an example fetch?

Ddave huh interesting, could you show an example fetch?

sathoro•11/12/23, 7:37 PM

const params = {
  url,
};

const queryString = new URLSearchParams(params).toString();

fetch(`https://app.scrapingbee.com/api/v1/?${queryString}`);

const params = {
  url,
};

const queryString = new URLSearchParams(params).toString();

dave•11/12/23, 7:37 PM

oh, that ,makes more sense lol. I was thinking it was a straight up standard HTTP proxy

Ssathoro my own IP, from where?

dave•11/12/23, 7:38 PM

why not spin up an instance on DigitalOcean or something?

dave•11/12/23, 7:38 PM

or is it a scaling problem too?

Ddave why not spin up an instance on DigitalOcean or something? 🙂

sathoro•11/12/23, 7:39 PM

I have a feeling that will be blocked already but yeah that is the next move if this doesn't work. this was supposed to be the easiest option but nobody offers it..

sathoro•11/12/23, 7:39 PM

might just use rotating residential proxy should work

dave•11/12/23, 7:40 PM

in theory you could use outbound TCP sockets and connect to a "normal" HTTP or SOCKS proxy.

GRPC doesn't have 401s...

what GRPC code are you returning?

CCB GRPC doesn't have 401s... 🙂 what GRPC code are you returning?

liam | helius.dev•11/13/23, 5:11 PM

set grpc-status header to PERMISSION_DENIED but didn't change anything

Lliam | helius.dev set grpc-status header to PERMISSION_DENIED but didn't change anything

CB•11/13/23, 5:13 PM

are you using some sort of GRPC gateway?

CCB are you using some sort of GRPC gateway?

liam | helius.dev•11/13/23, 5:14 PM

Using envoy

liam | helius.dev•11/13/23, 5:14 PM

Have a wasm plugin that for eg. will return 401 if no api key is present

liam | helius.dev•11/13/23, 5:14 PM

for http1 this works, for grpc the LB returns 520

Lliam | helius.dev Have a wasm plugin that for eg. will return 401 if no api key is present

CB•11/13/23, 5:15 PM

What that sounds like to me is the gateway you are using is translating the GRPC -> to http1 error codes incorrectly

CB•11/13/23, 5:15 PM

when the grpc request is authenticated does it work correctly?

CCB when the grpc request is authenticated does it work correctly?

liam | helius.dev•11/13/23, 5:16 PM

Yep it does

CB•11/13/23, 5:16 PM

yeah, so cloudflare part is working

CCB yeah, so cloudflare part is working

So to use Pages advanced mode I have to use this https://developers.cloudflare.com/pages/platform/functions/advanced-mode/

I did follow the docs, but like im struggling with putting the _worker.js in the actual output dir??

Like as you can see in the first photo, running the build command generates a _worker.js file, but it is not the one that I wrote, how do I get MY worker to be in the build directory? Keep in mind I'm using svelte

Panda•11/13/23, 7:20 PM

This is my wrangler.toml file, it is worth noting that my worker is located in /worker/index.js
