That works fine, I can see message in logs. But the catch-all doesn't work and I need to read all the inbound email and decide to insert / reject on worker. Instead CF reject it before the email is reaching to my worker.

Do you know if the dart support for workers is any good?

Piero512•3/22/24, 12:53 PM

It's just that the main works a little like a deprecated JS entrypoint

Piero512•3/22/24, 12:56 PM

ie. the startup script looks like the service workers flow.

Piero512•3/22/24, 12:58 PM

and also the js bindings are extremely basic

GoodluckH•3/22/24, 7:09 PM

let's say i have 10000 active users. And I need to do some jobs for each of them, ideally concurrently. wondering if this is achieveable using cf workers?

i looked at the Limits page, it says the limit is 6 for Simultaneous outgoing
connections/request, that sounds pretty limiting

should i programatically create and deploy many workers so i distribute load among workers?

GGoodluckH let's say i have 10000 active users. And I need to do some jobs for each of them...

Chaika•3/22/24, 7:12 PM

it's 6 per invocation/incoming request

Chaika•3/22/24, 7:13 PM

If your 10k active users all send http requests to your worker at the same time, Workers have no issue handling that load, and each of those requests has 6 Simultaneous outgoing requests it can make

GoodluckH•3/22/24, 7:14 PM

what does outgoing requests mean?

GoodluckH•3/22/24, 7:15 PM

like performing http requests inside of the worker?

Chaika•3/22/24, 7:27 PM

Sounds like you want CF for SaaS: https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/,
https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin/
You have to specifically setup each Customer Domain though, can do it through the API though. For example, all Shopify Custom Domains use CF For SaaS

You can use rate limiting rules. https://developers.cloudflare.com/waf/rate-limiting-rules/

Rate limiting rules · Cloudflare Web Application Firewall (WAF) docs

Rate limiting rules allow you to define rate limits for requests matching an expression, and the action to perform when those rate limits are reached.

GoodluckH•3/23/24, 8:24 PM

why would i need a queue if i can invoke wokers millions of times a day? let's say every day i have 10000 active users each needs to get info from 100 websites. so a worker basically just scrape the info.

in this case can't i just do a 10,000 * 100 for loop to call my worker 1 million times?

GGoodluckH why would i need a queue if i can invoke wokers millions of times a day? let's s...

Chaika•3/23/24, 8:53 PM

Queues are for more reasons for that,
to start with, you get 1k subrequests per worker invocation, only 6 at one time, and Workers can only call workers up to a certain depth (I forgot what, exactly). The user may disconnect before all your requests are done.

Queues also are for instances where your backend can't handle it at all at once. They let you trade off latency for throughput.

GoodluckH•3/23/24, 8:54 PM

interesting. how did you get 1k subrequests?

DarkDeviL•3/23/24, 11:20 PM

Was this the one you referred to with "fixed this"?

If not, you need to look around in you chain, all from where you are putting the message together, and to the point where you're seeing that error.

Somewhere in that chain, it appears that you're ending lines in your code just with

\n

\n

(

<LF>

<LF>

), which must be changed to

\r\n

Walshy•3/24/24, 1:06 AM

Yep, you can import the file and return it (it'll be uploaded as a module)

E.g.

import indexHtml from './pages/index.html';

export default {
  fetch(req) {
    const { pathname } = new URL(req.url);

    if (pathname === '/') {
      return new Response(indexHtml, { headers: { 'Content-Type': 'text/html' }});
    }

    return new Response('404 Not Found', { status: 404 });
  }
}

import indexHtml from './pages/index.html';

export default {
  fetch(req) {
    const { pathname } = new URL(req.url);

    if (pathname === '/') {
      return new Response(indexHtml, { headers: { 'Content-Type': 'text/html' }});
    }

    return new Response('404 Not Found', { status: 404 });
  }
}

thanhle•3/24/24, 1:49 PM

i really love workers and really enjoy using it. my question is: is there anyway I deploy a worker but dont go to egde network. I want the workers only deployed to a specific region not global. I try to use smart placement but not help. the reason I want to deploy worker to a specific region is when I benchmark the query Postgresql database by using CloudFlareWorker and AWS Lamba(aws lambda is deployed to only one region), the response time for aws lambda is TWICE FASTER than that of cloudflare workers. Thank you all.

alotabits•3/24/24, 2:07 PM

The Cache API allows interaction with the same cache used for fetch requests via caches.default. Is it possible to get or put the entries in this cache for a particular device type in a manner compatible with cache-by-device-type settings?

alotabits•3/24/24, 4:04 PM

So it’s not a special cache key value? As long as we construct a Request with the correct cf-device-type header when passing to cache get/put/delete it will work correctly?

That is `ticketdesk.ai`. You sent an email to `ticketdek.ai`
