Ok now I get that, I need to check latency. I tested KV and its around ~20ms. I wonder how much slower DO is.

HHello, I’m Allie!I would probably go with something like https://lucia-auth.com/

Thx, but does this work with CloudFlare Workers, has it been tested on CF Workers? Would really appreciate it

Hello, I’m Allie!•5/26/24, 3:59 PM

I've seen people use it on Workers, so yes

Hello, I’m Allie!•5/26/24, 3:59 PM

Whether everything works, idk. If you do find issues, I would recommend reporting them to the Lucia authors

haz•5/26/24, 4:00 PM

Sounds good, will probably need to look into what flags might be required, I'll test and hopefully post my findings here

antonio eldelpan•5/26/24, 4:32 PM

Given that cf workers are limited in cpu time, what is the recommended hashing algorithm to store securely passwords?

haz•5/26/24, 5:18 PM

From what I've read, here are the options:

https://developers.cloudflare.com/workers/runtime-apis/web-crypto/
https://developers.cloudflare.com/workers/runtime-apis/nodejs/crypto/
Or something purely written on JS and not a wrapper on top of something like C++ which is basically what Argon2 is. Not sure what Bcrypt uses but that is what is used by Lucua Auth @Puliczek

Say I want to have a DO that polls an endpoint for new data. I then want to have a worker that allows the user to stream events using SSE, getting a new event every time the DO finds new data. What's the simplest way to connect those two things together? Do I need to have the worker consume a websocket from the DO in order to get updates?

johtso•5/26/24, 9:54 PM

ah, I guess I can have the DO expose SSEs

.gwapes•5/27/24, 12:10 AM

I was looking on the Cloudflare api documentation and I couldn’t find what I was thinking of. When you view the dashboard and click on your worker and you can see the total amount of requests, errors sub requests etc, is it possible to get this info through a request? (Pls ping if you answer)

Hey team - how big are Cloudflare workers? E.g., ballpark how many worker invocations happen per day across all of cloudflare?

Kirk Ouimet•5/27/24, 7:03 PM

Billions?

James•5/27/24, 7:07 PM

More than that. I don't think any official numbers have been published recently, but this tweet is a good example: https://x.com/KentonVarda/status/1783996343813652801

An internal team dropped 12.5M requests per second on Workers and it worked just fine

Kirk Ouimet•5/27/24, 7:08 PM

WOWOWOW

Kirk Ouimet•5/27/24, 7:08 PM

thats incredible

Chaika•5/27/24, 7:09 PM

A good amount of Cloudflare features are internal workers too: https://blog.cloudflare.com/building-cloudflare-on-cloudflare
Like Zaraz, Cloudflare Challenges, Waiting Room, Image Resizing, Images, Mirage, Rocket Loader, etc. All Cloudflare Pages requests go through a worker too

James•5/27/24, 7:09 PM

All KV requests too, so much.

Chaika•5/27/24, 7:09 PM

It's Workers all the way down lol

James•5/27/24, 7:09 PM

I definitely wouldn't ever have any worries about my traffic scaling beyond Workers, haha

Walshy•5/27/24, 7:30 PM

let me see what number i can give

Walshy•5/27/24, 7:33 PM

eh we don't have public stats to go on

Walshy•5/27/24, 7:33 PM

but yeah, a lot

WWalshy but yeah, a lot

Chaika•5/27/24, 7:33 PM

that's a good number

Walshy•5/27/24, 7:36 PM

not yet, rapid reset was hitting 200 mil rps though

Walshy•5/27/24, 7:36 PM

so i'm sure we'll see a ddos hit that within the next 2 years

Alvee•5/27/24, 10:43 PM

can I use redis inside a worker ? does it support these protocols ?

Jayvi•5/28/24, 6:14 AM

Hello anyone can you please help me I forgot my email which I have used for cloudflare, my domain purchased from godaddy and in name server I have cloudflare name servers, so I want to know my cloudflare email, can you please guide me how to get email

I don't think there are metrics for that?

it doesn't show anything that can show the performance or anything useful

🌸algmon🌸•5/28/24, 1:12 PM

ok figured out

�

🌸algmon🌸•5/28/24, 1:13 PM

await fetch(url).ok is false

await fetch(url).ok is false

if it fails

�🌸algmon🌸```await fetch(url).ok is false``` if it fails

Isaac McFadyen•5/28/24, 1:22 PM

The okok field simply checks if the status is 200 (which it won't be if you're out of requests) so yes, that will work.

GuillaumeLakano•5/28/24, 4:12 PM

Hi!

About the workers subrequests limits (1000 for paid plan), if we need more, could we uses the last subrequests to trigger this same worker to continue ? ( or using a 3rd-party FaaS to loopback to the CF worker if required )

Queues or DurableObjects + Alarm seems to be very heavy works and money to just call 2 or 3 times a worker to finish some subrequests call
