Hello! I am building a proxy on Workers. If the proxied api is slow, will this cost me GB-s? So optimizing my api will save me money on workers? Or is only real computing power billed, like heavy calculations?

Chaika•5/22/24, 4:59 PM

If you're using Workers Standard (which everyone should be outside of Enterprises, and Durable Objects), you're only billed for CPU time (the time the worker is actively doing work) and not duration (GB-s), so the api being slower shouldn't cost you anymore, as the cpu is idle while waiting

Cyb3r-Jak3•5/23/24, 3:30 AM

Correct, there was no need for a seperate channel for it

Jjai_s What is the level of typescript support on workers?

Ian•5/23/24, 5:44 AM

fully supported. Nearly every example in the docs shows both JS and TS.

Can someone explain the difference between workers for platforms and standard? I couldnt unterstand it pretty well on internet. Thanks

advaith•5/23/24, 7:34 AM

I have a worker that runs every minute, checks if there are posts newer than the last post saved in KV, and forwards them if so. On the past few days, I've noticed posts being forwarded twice, which indicates that KV is returning outdated info a minute later. I've never seen this happen before; was there a recent change that would make KV take longer to update? Is there anything I can do to avoid this happening, other than changing the interval the worker runs on? (please ping with response)

Walshy•5/23/24, 8:52 AM

Workers for platforms is so you can turn workers into a SaaS product.
Docs give a good explanation: https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/

Walshy•5/23/24, 8:54 AM

Wonder if this is what we're seeing in #releases

I haven't had time yet to investigate.
There shouldn't have been any changes which could cause this but of you can confirm that behaviour I'd recommend posting in #kv

Walshy•5/23/24, 8:54 AM

WfP doesn't give you more limits (except more script count) and the cf properties is available in all workers

Walshy•5/23/24, 8:54 AM

What are you hitting exactly?

WWalshy What are you hitting exactly?

ehrenmann•5/23/24, 8:58 AM

Well i have my own basic dashboard for cloudflare API and manage few hundreds of domains. Each of them should have its own worker and each worker should save headers etc from each visitor. Would this be possible with normal workers? - also there is a limit of 500 workers per account right? Can i have more workers with WFP

Walshy•5/23/24, 8:59 AM

I'd recommend doing that in a single Worker but err yeah, you can have unlimited with WfP so if you really wanted to go that route it'd work

ehrenmann•5/23/24, 9:00 AM

What would you recommend for saving the information of the visitors. Should i use the hypersrive, d1… or maybe something else

Walshy•5/23/24, 9:01 AM

Depends on the information

Walshy•5/23/24, 9:01 AM

If it's for analytics and you just want to save like request count - Analytics Engine

Walshy•5/23/24, 9:01 AM

If you need an actual DB (e.g. auth) then yeah D1 or your own DB with Hyperdrive

ehrenmann•5/23/24, 9:03 AM

Ok thank you very much i appreciate it.

advaith•5/23/24, 9:17 AM

yeah looks the same - I think I first noticed it on 5/20. should I just repost that same message in #kv?

kindaraffy•5/23/24, 11:30 AM

Is an event handler (like fetch()) is always required even if you only use that worker in a service binding via RPC? I can't seem to deploy without specifying fetch.

kian•5/23/24, 12:12 PM

you don't need a fetch handler, but you do need a default export

kian•5/23/24, 12:12 PM

if you're not exporting your WorkerEntrypoint class as the default, Wrangler will get upset

DaniFoldi•5/23/24, 3:32 PM

Hey, workers (and more specifically, Durable Objects with their websocket hibernation api) would be perfect, assuming you can adapt your data storage solution. #durable-objects is the best channel to ask if you get stuck, the docs don't contain enough examples to understand everything

Togira•5/23/24, 3:33 PM

thanks for the quick answer :) I'll make same research regarding durable objects then

Jameson•5/23/24, 4:39 PM

how can i clear everything i have cached using the workers cache api cache.put()?? i tried a curl {purge_everything:true} using the api but the cached response is not being deleted

kap•5/23/24, 5:33 PM

I'm looking for an example of a successfully built workers-sdk / workerd stack --- I'm fixing a bug in workerd myself and would like to compile it end-to-end. Anybody have any examples / resources?

Phisn•5/23/24, 5:33 PM

Question regarding durable objects (DO). If I have one DO class but let’s say 100 instances. Will I be billed 100 x 128mb or only once 128mb if they all do in practice not occupy more than that? It is not explained very well in the documentation

Chaika•5/23/24, 5:39 PM

Those footnotes go over it pretty well:

4 Duration is billed in wall-clock time as long as the Object is active, but is shared across all requests active on an Object at once. Once your Object finishes responding to all requests, it will stop incurring duration charges. Calling accept() on a WebSocket in an Object will incur duration charges for the entire time the WebSocket is connected. If you prefer, use state.acceptWebSocket() instead, which will stop incurring duration charges once all event handlers finish running.

5 Duration billing charges for the 128 MB of memory your Durable Object is allocated, regardless of actual usage. If your account creates many instances of a single Durable Object class, Durable Objects may run in the same isolate on the same physical machine and share the 128 MB of memory. These Durable Objects are still billed as if they are allocated a full 128 MB of memory.

Chaika•5/23/24, 5:39 PM

if they were all constantly active, you would get billed 100 x 128 mb. Otherwise it's just a static billing for 128 mb x the time that instance is active

CChaika if they were all constantly active, you would get billed 100 x 128 mb. Otherwise...

Phisn•5/23/24, 5:40 PM

So I could read it as if they are still billed individually?

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

Phisn•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

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?
