Yeah, I don't think that would be able to be run on any Cloudflare products at the moment. You would need a VPS or something like Fly/AWS Lambda(or another service that can run Node)

Hey, can anyone give a gauge of the hardware performance underpinning the Workers platform? Given that "CPU time" is a billed metric, and we have no gauge of how many ops/sec or something the isolate/thread can do, it is quite arbitrary and hard to gauge. Any hardware acceleration for crypto operations? I'm guessing the hardware is constantly evolving and different depending on the data centre... but perhaps someone can comment or improve my understanding...?

For example, verifying JWTs using the SubtleCrypto API is common on every request for an API, and also a computationally heavy operation. And just from experience I'm getting the feeling that the CPU available to Workers feels pretty slow compared to other "single vCPU" runtimes I've used... any insights?

Brett Willis•6/19/24, 9:39 PM

Also I've been finding that our Workers get evicted crazy fast. Like it gets evicted in under 5 seconds a lot of the time, and then does a cold start for a request to the same data centre 5 seconds later. Is that normal or what? On a cold start it also has to do a bit of CPU work like importing crypto keys etc.
The docs say that the

env

env

object can be equal by reference until the env variables or bindings change, so we cache our state on the env object but it gets evicted crazy fast.

Brett Willis•6/19/24, 9:42 PM

I've got one too that verifies a JWT and sends a response, and it tends to use upwards of 80ms CPU per request which feels like a lot. But I've got a feeling that a lot of that CPU is related to spinning up a cold environment as it goes down significantly when I ramp up the RPS to keep the instance alive.

Brett Willis•6/19/24, 9:46 PM

Ah I see, that is interesting... It felt natural because the application state is explicitly tied to the env config, and the docs says it's the same object reference between requests. If using global vars I'd have to reason about invalidating when env config changes.
Caching on env does seem to work, but it just seems to get evicted pretty promptly...

Original message was deleted

Brett Willis•6/19/24, 9:46 PM

Are there any docs about this env being a software update that causes eviction?

Brett Willis•6/19/24, 9:52 PM

Hmm ok. Well it's worth a try, I'll try caching on

globalThis

globalThis

instead of

env

env

and let you know if that changes our crazy-fast eviction.

Ttoby357 I'm wondering if this would cache the result from a sub worker

Hello, I’m Allie!•6/20/24, 7:08 AM

Service Bindings are not cached automatically, you need to call the Cache API manually

MISANTHROPIC J•6/20/24, 6:18 PM

Hi all! Noob here, sorry if this is a silly question, but I'm not finding clear answers. Are workers only able to be deployed on the dev urls created by cloudflare on a free plan ?

Context: I'm trying to set up a reverse proxy worker for dispenseapp so my dispense store url is "mydomain.com/store" the documentation on dispenseapp seems straightforward and even updates code automatically when updating desired store url or adding multiple stores. After setting up everything step by step it works fine on the dev url, but the route pointed at my domain doesn't work at all. I feel like I'm missing a critical step to connect this worker to my domain on cloudflare besides setting up my

route : domain.com/shop*

Zone: domain

Hi question about the workers execution time

I'm migrating from Supabase edge function cause they have a hard limit on the function execution time (2 seconds), does anyone know what is the limitation on Workers?
I'm trying to generate a pdf which contains ~30 pages, which could take ~10s.

Chaika•6/20/24, 9:18 PM

there's no hard limit on duration (other then the fact that runtime upgrades happen and your worker only gets 30s to finish its work). There are limits on CPU Time (time the cpu is active/doing stuff, most importantly excludes time waiting on i/o like fetchs) and Memory: https://developers.cloudflare.com/workers/platform/limits/#worker-limits

In https://blog.cloudflare.com/pages-workers-integrations-monorepos-nextjs-wrangler, under the "What’s next for the convergence of Workers and Pages?" there is a bit about Pages features coming soon to Workers - Serve static assets from Workers. You will be able to deploy and serve static assets as part of Workers – just like you can with Pages today – and build Workers using full-stack frameworks!

I'm curious, are there any new updates on this work?

Walshy•6/21/24, 8:27 AM

Just that it's in development and we're working on it

ItsWendell•6/21/24, 9:37 AM

In Cloudflare (Workers), how does the 'fetch' caching behavoir work when the fetched resource is a redirected to somewhere else?

Let's say we have a cache everything and TTL on a specific fetch request, that fetch requests ends up doing a temporary redirect to another URL, will it, the URL that is being redirected to, be fetched from cloudflare's cache if available?

A concrete example for our Storyblok scenario: If we don't have a cache version (cv) available and we fetch

/v2/cdn/stories/home?key=234234234

/v2/cdn/stories/home?key=234234234

, Storyblok will redirect this to a link that does have the cache value (cv) query param

/v2/cdn/stories/home?cv=2342342234&key=234234234

/v2/cdn/stories/home?cv=2342342234&key=234234234

, will the second URL be fetched from the cloudflare cache or not? Preferably in this case, if we get a redirect status code from Storyblok, we don't want to cache that response. But if it redirects to an URL that does have the cache version (cv) included, and we already have that cached, we want to actually retrieve it from the cloudflare cache if available there.

Might I need to add a response status code specific cache rule? Or how does the caching behavoir work when redirects are involved?

Xiao 🥑•6/21/24, 1:40 PM

Hi I'm to create a simple api with itty-router, but ran into this error, anyone has any idea how to fix this?

A hanging Promise was canceled. This happens when the worker runtime is waiting for a Promise from JavaScript to resolve, but has detected that the Promise cannot possibly ever resolve because all code and events related to the Promise's I/O context have already finished.

const router = Router();

router.get('/api', () => {
    return new Response('Welcome to the inspecti api', {
            headers: { 'Content-Type': 'text/plain' },
    });
});

router.all('*', () => new Response('404, not found!', { status: 404 }));

export default {
    fetch: (request: Request, env: Env, ctx: ExecutionContext) => router.handle(request, env, ctx),
} satisfies ExportedHandler<Env>;

SonyC•6/21/24, 3:19 PM

Good day guys.
I wanna ask for advices about how deploy a worker API that I implemented using D1 as storage and a react SPA built using vite, that I used to serve using express.js.
1 - Is it good to deploy the worker as is and in parallel the react SPA in pages? Will this be ok?
2- Will this need cors whitelist or something?
3 -Will be better to serve the SPA using getAssetFromKV from '@Cloudflare/kv-asset-handler'?
4- Will using functions will be better for my case?

I'm reading now about Workers Sites, will this be an option?

yeah I would definitely recommend folks just stick with Resend, Postmark, SendGrid, SES, or many others rather than using MailChannels. Security issues and the company's communication has made it impossible for me to recommend MailChannels to anyone.

In exchange for being an early user, you will receive a significantly discounted price when the improved commercial service launches later this year.

The API will continue working. We have been providing email delivery service continuously since 2012 and have no intention to pull any rugs. The only thing that is ending is the provision of a free service tied to Workers IPs.
