on WfP can you use native RPC to talk to other workers on the same namespace? do they have to be service bindings/workers? Just trying to clarify that aspect

Only if you have less than 1000 customers.
Take a look at https://developers.cloudflare.com/r2/reference/limits/

Beny•5/21/24, 3:40 PM

I think they'd prefer you used 1 bucket and give each customer a folder, but there are no technical limitations if you wanted 1 per customer.
See Sid's post here: r2

rob•5/21/24, 3:40 PM

Yeah I don't mind doing one drive and partitioning g with "folder" prefixes per customer either

rob•5/21/24, 3:40 PM

Yeah looking for confirm on which makes more sense .

Did Sites ever work with Workers for Platforms? The big thing with Sites was just that it had a package/upload tool(Wrangler) that was supported by the team. Everything it can do, you can build yourself

rob•5/21/24, 8:44 PM

yeah it esbuild or something bundles ur frontend into like static assets? thne id do a dist or static folder and like app.servestatic on hono or something, but i saw in thier docs they said it's been dscontinued

Sites was deprecated many years ago

yah not sites I was talking about serve static files aspect

Walshy•5/21/24, 9:34 PM

That's Sites :p

Walshy•5/21/24, 9:35 PM

Pages is the recommended way for now

With convergence static assets will come to Workers officially (Sites was always quite a hack) but that's still a way off

rob•5/21/24, 9:39 PM

welp. lol . alright so for WFp if someone wants to deploy static frontend jsut use pages API or something liek that? it won't be able to be served from the same worker ?

no, you can spin up a site though and invoke it (we have customers doing similar just not through wfp)

I want to pass some custom args to the user worker without modifying the original request. Is this not possible right now? could be a good use case of the second parameter in dispatcher.get(..).

Gotcha, I guess I can do that. Would the cfcf object still be stripped when passing the RequestRequest through?

ehrenmann•5/22/24, 7:37 PM

hi guys, im new to all this so this may be a stupid question.
I want to make a worker that gets visitors data from headers (useragent...) and want to save this somewhere. i saw that there is hyperdrive and as far as i understand it, i can connect my db. are there any limits for reading/writing and also for this kind of worker should i get worker for platforms? are there any benefits?
thanks

Abdallah Abis•5/22/24, 9:58 PM

Hey Folks,
In docs here https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/get-started/dynamic-dispatch/
I see that await userWorker.fetch(request)await userWorker.fetch(request) will throw an error with message that starts with Worker not foundWorker not found if the worker is not found.
What if I'm using this with RPC, when the worker is not found I get internal error.internal error. and not Worker not foundWorker not found how can I configure this, or how would I know that if the worker threw exception or not found

Owl Reddy•5/25/24, 2:07 AM

I'm the newest one here but I guess you can use cloudflare analytics for that kind of data as it's easy to do time series queries with that besides normal queries. Hyperdrive needs Postgres which you gotta deploy urself or use hosted services and it's maily for read heavy workloads.

Hey folks,
Doing a PUTPUT request to /secrets/secrets returns this:

{
    "result": {
        "name": "TEST",
        "type": "secret_text"
    },
    "success": true,
    "errors": [],
    "messages": []
}

{
    "result": {
        "name": "TEST",
        "type": "secret_text"
    },
    "success": true,
    "errors": [],
    "messages": []
}

But doing a GETGET just after that to the same endpoint returns this:

{
    "result": [],
    "success": true,
    "errors": [],
    "messages": []
}

{
    "result": [],
    "success": true,
    "errors": [],
    "messages": []
}

Any idea why secrets aren't being set?

Abdallah Abis•5/28/24, 4:50 PM

I found the issue, but have no idea how to fix it.
So assuming x-script-namex-script-name is deployed to both namespace-devnamespace-dev and namespace-prodnamespace-prod (namespace-dev first)

If I do a PUTPUT to /workers/dispatch/namespaces/namespace-prod/scripts/x-script-name/secrets/workers/dispatch/namespaces/namespace-prod/scripts/x-script-name/secrets
The API hits /namespaces/namespace-dev/scripts/namespaces/namespace-dev/scripts and not namespace-prodnamespace-prod for some reason.
I think it hits the namespace that it was deployed to first.

I did rename the worker and deploy it to namespace-prodnamespace-prod first and add a secret to it and it worked, but deploying the same renamed worker to namespace-devnamespace-dev and trying to add a secret to the last deployed worker it actually ended up added to the namespace-prodnamespace-prod one.
In other words, the dispatch namespace in this API has no effect it just looks in all the user workers on the account and picks the first one deployed and not the one in that particular workspace.

avogadro•5/28/24, 8:15 PM

I am calling return await userWorker.handleRequest(request)return await userWorker.handleRequest(request). When i look in the logs, I see that it says "outcome": "cancelled". Any ideas?
the handleRequest implementation is just return new Response('Hello World!');return new Response('Hello World!');

Isaac McFadyen•5/28/24, 9:04 PM

So I believe you're confusing latency and CPU time. 1-2ms would be a reasonable CPU time for a simple JSON worker, and 28-32ms would be a reasonable wall time for that worker. I can't imagine any scenario where a simple JSON worker is using 28-32ms of CPU time per request, that's very high.

Isaac McFadyen•5/28/24, 9:04 PM

?cpu-time

Flare•5/28/24, 9:04 PM

CPU Time: the amount of work the CPU needs to do, measured in msms. More CPU-heavy things will increase it (for example, hashing passwords). This is not the same as the time a fetchfetch request takes.
Wall Time: the actual amount of time a Worker runs for, as though you measured it with a clock or your browser DevTools

Aalgads Im talking about the execution speed of the user worker to receive the payload a...

Isaac McFadyen•5/28/24, 9:08 PM

Ah OK, I misunderstood then. Just to clarify - you are not billed for ~30ms, you are billed by CPU time.
