Just to confirm. The footnote means each DO instance and not DO class?

PPhisn Just to confirm. The footnote means each DO instance and not DO class?

Chaika•5/23/24, 5:44 PM

yes, I mean each instance of a DO class is, itself, a single Durable Object

PhisnOP•5/23/24, 5:46 PM

Because, since they didn’t use the word each or individually in the end, I think the description is ambiguous.

At least for me it doesn’t seem wrong to assume, that they mean that all instances combined will always take at least 128 mb of memory

PPhisn Because, since they didn’t use the word each or individually in the end, I think...

Chaika•5/23/24, 5:46 PM

Durable Object Namespace is the name of the binding/the overall object

Neiki•5/23/24, 7:26 PM

i have an cloudflare worker that fetches another api, can i send more than 100mb of size in that fetch call or does the upload limit of 100mb (cloudflare standarts) also count for worker sending files to stuff?

Neiki•5/23/24, 7:26 PM

and if yes can i increase that?

Kurzon•5/23/24, 9:14 PM

I really want to use global scope for asynchoronous operations

Kurzon•5/23/24, 9:14 PM

But I cannot

Kurzon•5/23/24, 9:14 PM

How would you guys deal with this?

Cyb3r-Jak3•5/23/24, 9:17 PM

Store that data in KV and read it on request

CCyb3r-Jak3 Store that data in KV and read it on request

Kurzon•5/23/24, 9:18 PM

But i want it globally available, not just in the fetch function itself

Cyb3r-Jak3•5/23/24, 9:18 PM

If the JSON is local, then depending on the size of the JSON you can bundle it into the worker

ALECKS•5/24/24, 1:01 AM

Anyone know of any npm libraries that work on CloudFlare Workers to edit images? I'm looking to specifically change colors (convert image to duo-tone). I looked through the CF Images product but that doesn't seem to allow the editing I need. A library like sharpsharp would be great, but that doesn't seem to work as far as I can tell.

hi anyone know "zaraz context enricher worker"? I created one, but it didn't work at all

Vittorio•5/24/24, 12:27 PM

hello guys we are trying to run Workers on a small Shopify Website, is it possibile to active the O2O feature without purchase an enterprise license?

Vittorio•5/24/24, 12:28 PM

Is there something alternative that we could do in order to run Workers/proxy on a shopify website?

Hello everyone, I'm trying to create a discord bot using workers. but for some odd reason, when i try to save the endpoints url in discord developer portal, it throws me with an Invalid Form Body, and doesn't let me change the interactions endpoint.

Do you handle the PING type and the verify the request

dL^ | Creditcoin•5/24/24, 7:27 PM

hi, is it possible to configure unsafe bindings similar to with wrangler.toml with quick edit or inside quick edit instead of using Wrangler CLI?

SML•5/24/24, 8:11 PM

Is there a way to install the jsjs library so I can get code completion in Pycharm?

WTH is Late usage ?

Jadugar_Jaggu•5/25/24, 2:51 PM

does anyone know about it? after shifting to new standard pricing, my overall costs have been doubled and getting very confusing bills

Jadugar_Jaggu•5/25/24, 2:53 PM

I noticed a "Late Usage" charge on my current bill. I already paid the bill for the period of February 25 to March 24, so I'm not sure why I'm receiving another bill this month. Could anyone please clarify this for me?

Well I already tried it, but cloudflare is not letting me to submit new tickets and showing old tickets which are already solved.

I kindly request cloudflare Discord support to help me out here.

Jadugar_Jaggu•5/25/24, 3:20 PM

also I prefer not to re-open the existing ticket to avoid causing confusion for the support team. However, Cloudflare is not allowing me to submit new tickets, which leaves me feeling as though I'm being forced to pay random bills.

HHello, I’m Allie!I'm wondering, what does `itty-durable` do that RPC doesn't?

Kevin•5/25/24, 11:25 PM

itty-durable (current version) basically did the following:

PROS:

brought RPC [years] before the official RPC release (which is great, btw)
added auto persistence
added some middleware convenience to access DOs by string ID (which is super common... as you likely want a DO based off some other identifier)

CONS:

required itty-router because the middleware was required to wire up the Worker side of the RPC calls

---

The NEXT version (upcoming) shrinks drastically as a result of the recent RPC changes, so for only 400 bytes you get:

auto persistence
persist to/from any data store, not just the default DO storage (e.g. persist to/from D1, KV, R2, supabase, an external API, whatever)
no router requirements... works with any/no router at all (hono, itty, vanilla, etc)

(more details and example code here: https://x.com/kevinrwhitley/status/1792416233968816500)

how do i acess env variables outside the fetch() method in workers?

haz•5/26/24, 12:32 PM

I want to try and make a application using CloudFlare. I can host the frontend app in Pages and Backend on Workers but I am trying to find a solution for Authentication.

These are my current choices:

Use a CloudFlare service for Auth if there is one (Couldn't find one) I need one with Sign in With Google, MFA, Sending Forget Email from Own Domain
Implement it using CloudFlare D1 + Worker but writing the code on my own like using the argon2 library and other libraries.

Please advise, I would ideally like to use a pre-built service from CloudFlare

Hello, I’m Allie!•5/26/24, 12:33 PM

I would probably go with something like https://lucia-auth.com/

Lucia

Lucia documentation

Lucia is an open source auth library that abstracts away the complexity of handling sessions.

Puliczek•5/26/24, 1:05 PM

hello group

I have built cloudflare worker with hono. I would like to add authentication Bearer Auth with usage, for example user can hit only 100k/monthly endpoint. Whats the best way to do that? Should I go with KV or Durable objects to store API Keys + usage? Or is there better way to do that?

Unsmart•5/26/24, 3:00 PM

DO is the only option of those 2 that could be used in that way

UUnsmart DO is the only option of those 2 that could be used in that way

Puliczek•5/26/24, 3:05 PM

Thanks. Can't get why DO is better for that.

Unsmart•5/26/24, 3:06 PM

KV is eventually consistent and can only be written to the same key 1 time per second. DO is strongly consistent and can have hundreds to thousands of hits a second

Puliczek•5/26/24, 3:11 PM

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/

haz•5/26/24, 3:58 PM

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

Hhaz Thx, but does this work with CloudFlare Workers, has it been tested on CF Worker...

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

johtso•5/26/24, 9:36 PM

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)

import * as assert from 'node:assert'; const scores = await fetch('./scores.json'); const data = await scores.json() as any; assert('weights' in data, `Failed to get weight data of scores.json`); assert('max_scores' in data, `Failed to get max scores data of scores.json`); export const WEIGHTS: { [key: string]: number; } = Object.freeze(data['weights']);

Just to confirm. The footnote means each DO instance and not DO class?
