Like. If each instance uses 24/7 1mb. Do I get billed 100 x 128mb?
CCorrect, as the footnote says
Duration billing charges for the 128 MB of memory your Durable Object is allocated, regardless of actual usage
PJust to confirm. The footnote means each DO instance and not DO class?
Cyes, I mean each instance of a DO class is, itself, a single Durable Object
PBecause, 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

CDurable Object Namespace is the name of the binding/the overall object
Ni 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?
Nand if yes can i increase that?
KKI really want to use global scope for asynchoronous operations
KBut I cannot
KHow would you guys deal with this?
CStore that data in KV and read it on request
KBut i want it globally available, not just in the fetch function itself
CIf the JSON is local, then depending on the size of the JSON you can bundle it into the worker

AAnyone 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
sharp would be great, but that doesn't seem to work as far as I can tell.An/m, found a great one: @cf-wasm/photon
Ehi anyone know "zaraz context enricher worker"? I created one, but it didn't work at all
Vhello 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?
VIs there something alternative that we could do in order to run Workers/proxy on a shopify website?
SHello 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
Dhi, is it possible to configure unsafe bindings similar to with wrangler.toml with quick edit or inside quick edit instead of using Wrangler CLI?
SIs there a way to install the
js library so I can get code completion in Pycharm?
JWTH is Late usage ? 
Jdoes anyone know about it? after shifting to new standard pricing, my overall costs have been doubled and getting very confusing bills
JI 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?

JWell 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.

Jalso 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.
Wif you do Billing -> Other are you able to create?
Jyea I created one that way, here is ticket no. 3274941
Kitty-durable (current version) basically did the following:
PROS:
The NEXT version (upcoming) shrinks drastically as a result of the recent RPC changes, so for only 400 bytes you get:
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)
- 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)
Khow do i acess env variables outside the fetch() method in workers?
HI 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:
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.
HI would probably go with something like https://lucia-auth.com/
Lucia
Lucia is an open source auth library that abstracts away the complexity of handling sessions.
Phello 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?

UDO is the only option of those 2 that could be used in that way
PThanks. Can't get why DO is better for that.
UKV 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
POk now I get that, I need to check latency. I tested KV and its around ~20ms. I wonder how much slower DO is.
HThx, but does this work with CloudFlare Workers, has it been tested on CF Workers? Would really appreciate it
HI've seen people use it on Workers, so yes
HWhether everything works, idk. If you do find issues, I would recommend reporting them to the Lucia authors
HSounds good, will probably need to look into what flags might be required, I'll test and hopefully post my findings here
AGiven that cf workers are limited in cpu time, what is the recommended hashing algorithm to store securely passwords?
HFrom 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

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