It should appear. I believe it’s at the end of the DNS records because it’s a Cloudflare one and not a standard one.

AnotherAlex•2/28/24, 3:16 PM

Thanks. That’s what I originally thought but I can’t find anything in the code that should do that. Anything that needs setting up on first request is done inside fetch, as it requires env vars. Is the Date.now() time at the start of fetch function accurate? I know it only updates on I/O operations but not sure if “fetch has just been called” is one.

kian•2/28/24, 3:20 PM

It'll be pretty accurate, yeah.

Rasel Rana Rocky•2/28/24, 3:36 PM

Hi, I hope it's not too dumb question.
I see that CF workers has a limit of maximum 6 outgoing requests simultaneously.
So, if somehow a single worker gets more than 6 simultaneous requests and I call auth service using

fetch()

fetch()

from the worker, then the requests above the limit will start failing?
I'm decoupling everything into multiple microservices and each request might make more than 1~15 requests to other services, both internal and external.

kian•2/28/24, 3:40 PM

It's 6 outgoing subrequests per incoming request.

kian•2/28/24, 3:41 PM

If you have 10 people hitting the same Worker, each one of those Worker invocations can make 6 outgoing subrequests concurrently.

Rasel Rana Rocky•2/28/24, 3:45 PM

Ah that makes more sense. Thanks

setup locks in a persisent store (KV, D1, Durable, whatever meets your usecase needs best).

JoeDoe•2/28/24, 9:29 PM

So all workers start with the fetch() function and thats it?

Chaika•2/28/24, 9:33 PM

The fetch function/handler is just one of (although the most common) Workers handlers, which is ran on every request to the Worker: https://developers.cloudflare.com/workers/runtime-apis/handlers/fetch/

Fetch Handler · Cloudflare Workers docs

Incoming HTTP requests to a Worker are passed to the fetch() handler as a request object. To respond to the request with a response, return a Response …

Chaika•2/28/24, 9:34 PM

There are other handlers. Email handlers for Email Workers, Queue Handlers, Scheduled Handlers (Cron), Tail Workers and their handlers, Durable Object with Fetch & Alarm handlers

Chaika•2/28/24, 9:35 PM

global scope is always evaluated/ran first in startup technically, not the fetch handler. For example Workers have no cold starts by loading the Worker during the TLS Connect, which would run global scope and fetch would only run when/if the request gets there

JoeDoe•2/28/24, 9:36 PM

so for example, if I wanted a worker that will just do a API call each 5mins, would fetch be the one I use?

JoeDoe•2/28/24, 9:36 PM

for right now, just call a api each 5 mins, console out the data

You would want cron triggers, and the scheduled handler

Scheduled Handler · Cloudflare Workers docs

When a Worker is invoked via a Cron Trigger, the scheduled() handler handles the invocation.

alan•2/28/24, 10:54 PM

is there an easy way for me to get the current memory footprint of my worker?

i have a memory sensitive application that i'm hoping to be able to attach logs to

alan•2/28/24, 10:54 PM

or maybe i should be posting on the help page?

Isaac McFadyen•2/29/24, 12:07 AM

There's no way, unfortunately.

FISK•2/29/24, 12:17 AM

Does workers free tier have any limitation on concurrency, e.g how many instances of a single worker can run at once?

Isaac McFadyen•2/29/24, 12:26 AM

~~No.~~ Sort of.

Isaac McFadyen•2/29/24, 12:27 AM

You may be rate-limited if you request Workers too quickly, however. Let me see if I can find the docs.

Isaac McFadyen•2/29/24, 12:27 AM

Isaac McFadyen•2/29/24, 1:49 AM

Yes, it's routed internally on the Cloudflare network.

No, you can only use workerd

Thanks - I finally found it. It isnt at the end, but is written as a weird CNAME record with the R2 identifier of it. I think it would just make more sense to keep all the CF records in a seperate list under the traditional DNS records?

Old Man Maker•2/29/24, 8:34 AM

Hi - I'm not quite groking HONO

I am attempting to write an image into an R2 bucket - but the HONO request body returned is not happy

        const body = await c.req.parseBody();
        c.env.R2_MY_BUCKET.put('test.png', body);

        const body = await c.req.parseBody();
        c.env.R2_MY_BUCKET.put('test.png', body);

Type 'BodyData' is missing the following properties from type 'ReadableStream<any>':..........

Any assist?

If you astro site is static, it can already run completely for free.

Hello, I’m Allie!•2/29/24, 10:43 AM

I mean that, by default, doesn’t Astro use sharp during build, which then allows the entire shebang to be served statically?

Even the images?

Hello, I’m Allie!•2/29/24, 10:44 AM

You don’t need the Image Service if all of the images are pre-generated
