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

JJoeDoe 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/

Cloudflare Docs

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

JoeDoeOP•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?

JoeDoeOP•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.

JoeDoeOP•2/28/24, 9:38 PM

hmmm I see I see

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

https://developers.cloudflare.com/workers/platform/limits/#burst-rate 1000 requests per minute on Free.

Santosh•2/29/24, 12:34 AM

In case of smart placement, would the request still be routed thru Pops to the Worker location?

Isaac McFadyen•2/29/24, 1:49 AM

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

Unsmart•2/29/24, 3:03 AM

No, you can only use workerd

Isaac McFadyen•2/29/24, 3:38 AM

(which is what is used in the production Cloudflare Workers environment)

Old Man Maker•2/29/24, 8:32 AM

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?

zegevlier•2/29/24, 10:21 AM

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

PPatrick Star Not if you enable the adapter, which is required for the image pipeline.

Hello, I’m Allie!•2/29/24, 10:39 AM

Then it isn’t static, no?

Hello, I’m Allie!•2/29/24, 10:40 AM

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?

Hello, I’m Allie!•2/29/24, 10:43 AM

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

PPatrick Star Rezising etc is useful

Hello, I’m Allie!•2/29/24, 10:45 AM

Yes, but if the dimensions of the image are available at build time, then you are wasting cycles resizing images on the fly

JJoeDoe Is there a limit to how long a worker can run?

Hello, I’m Allie!•2/29/24, 10:59 AM

30 seconds of CPU time, and theoretically indefinite runtime, though it may be evicted after 30 seconds

JoeDoeOP•2/29/24, 11:00 AM

oh cpu time is quite different from actual time right?

JoeDoeOP•2/29/24, 11:00 AM

I need my worker to get some data, but the initial 'sync' might take like 10mins+

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