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.

GoodluckHOP•3/23/24, 8:54 PM

interesting. how did you get 1k subrequests?

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

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 });
  }
}

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' }});

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.

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?

A

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?

yeah you'll want to declare a module like:

}

declare module '*.html' {
  const value: string;
  export default value
}

declare module '*.html' {
  const value: string;
  export default value
}

declare module '*.html' {

I have a project in which I have to have a WebSocket connection on 24/7, watching for a (rare) event. If that event happens, I need to run some code, then restart the WebSocket and watch for the event again.

Is Workers suitable for this? From my understanding, there's no limit on wall time, so this would be feasible as long as the total CPU time stays under 10ms

Ok what if like cloudflare team works on less things but finish them instead of just having 100 things in beta? Like what? Probably wrong channel for this but i think it gets the most attention from cloudflare team so i hope anyone sees this

W

Walshy•3/25/24, 11:47 AM

Things that are in beta go GA when they're ready to.

I think you'd rather we call it beta than have a "production ready" product that isn't production ready.

I have a general cache question:
I am using Hono's cache middleware to set the cache:

cacheControl: "public, max-age=600"

cacheControl: "public, max-age=600"

When the endpoint is hit in Postman, it always returns

public, max-age=600

public, max-age=600

in the response headers.
When the endpoint is hit from a browser, it returns

public, max-age=14400

public, max-age=14400

in the response headers.

Having said that, it does seem like the browser does respect the 600 seconds. I'm wondering why it shows 14400
