Chaika•3/13/24, 6:43 PM

the actual write? Well, KV only has two central stores, one in US, one in EU, so slow from some locations.
for seeing those changes? If a location had viewed that key, it'll be cached for a min of 60s, until they pull from central store again and see update

Hello! I am new here and sorry if this is a noob question, I am running Android 11 and I was going to make a discord bot using discord.js that runs on workers. But when i tried to install C3 on termux, it gave me an error on one of the post install steps in some dependency. Can someone help me troubleshoot my problem?

Hey

I would stop you a bit short though, Cloudflare Workers are not node.js, they instead run on V8, same Javascript Engine as Chrome and similiar Web Environment. There is some nodejs compatibility but no net support/CF only supports TCP Sockets through a special interface. Additionally, Discord bans CF IPs from their CDN except for ephemeral media/static things like Avatars, and they banned CF entirely from Gateway for a while, which I think is still active? Eitherway it just won't really work.

Instead of Gateway bots you can do Interactions Bots/slash commands (https://discord.com/developers/docs/tutorials/hosting-on-cloudflare-workers), but they're semi-limited.

Ah so DiscordJS doesnt work on workers as a diurable object type thing ?

hi all, I am trying to create a worker which proxy to my pages on suffix. I have this code for worker.js but it is not working as it throws an error as page not found.

// Export a default object containing event handlers
export default {
  // The fetch handler is invoked when this worker receives a HTTP(S) request
  // and should return a Response (optionally wrapped in a Promise)
  async fetch(request) {
    // Parse the request URL
    const url = new URL(request.url);

    // If the request URL matches '/blog1', proxy it to the Cloudflare Pages site
    if (url.pathname.startsWith('/blog1')) {
      // Construct the proxied URL
      const proxiedUrl = 'https://coderabbit-docs.pages.dev' + url.pathname;

      // Proxy the request to the specified URL and return the response
      return fetch(proxiedUrl, request);
    }

    // For other requests, return a default response
    // return new Response('Welcome to my Cloudflare Worker!', {
    //   headers: { 'Content-Type': 'text/plain' },
    // });
  },
};

// Export a default object containing event handlers
export default {
  // The fetch handler is invoked when this worker receives a HTTP(S) request
  // and should return a Response (optionally wrapped in a Promise)
  async fetch(request) {
    // Parse the request URL
    const url = new URL(request.url);

    // If the request URL matches '/blog1', proxy it to the Cloudflare Pages site
    if (url.pathname.startsWith('/blog1')) {
      // Construct the proxied URL
      const proxiedUrl = 'https://coderabbit-docs.pages.dev' + url.pathname;

      // Proxy the request to the specified URL and return the response
      return fetch(proxiedUrl, request);
    }

    // For other requests, return a default response
    // return new Response('Welcome to my Cloudflare Worker!', {
    //   headers: { 'Content-Type': 'text/plain' },
    // });
  },
};

If I hit my domain with suffix, it goes to 404 .

Chaika•3/14/24, 1:27 PM

sounds like you're hitting this:

On the Unbound billing model, scheduled Workers (Cron Triggers) have different limits on CPU time based on the schedule interval. When the schedule interval is less than 1 hour, a Scheduled Worker may run for up to 30 seconds. When the schedule interval is more than 1 hour, a scheduled Worker may run for up to 15 minutes.

although that mentions Unbound, I would imagine Standard would be the same

Is there any way to check the compatibility version/flags on a deployed worker? I can't use the Header.getSetCookie function because it doesn't exist, although the code editor reports it existing on the type.

You could hit the API to see what it's currently set to, but that's about it.

kian

kian•3/14/24, 1:59 PM

The types aren't aware of your compat flag unless you set them up to point to a specific date, so it probably is always showing you the latest

If I am using the mailchannels API in my worker to send emails. Does my domain need to be on Cloudflare? Or does it just need have the DNS Records?

Mitya•3/14/24, 2:23 PM

Is something up with Workers today? I test locally, but with the remoteremote flag, and in my console output I'm getting lots of

[object Object]

[object Object]

references for things that are definitely not, 100% note, objects - they're just strings. This is shown by instead logging the result of encodeURIComponent(myStr)encodeURIComponent(myStr), and the problem goes away. Obviously it's hard to give a reproducible example, but is there anything that might be causing this? It's just started happening today, in multiple endpoints of my code, and wasn't happening before.

Mitya

M

Mitya•3/14/24, 2:24 PM

The objects are illusory; when I ask my PG util what query it's about to run, it says it contains

[object Object]

[object Object]

. This would obviously result in a query failure, but the query runs fine, which again suggests that this is some sort of illusion in Workers or the Workers console output.

  // The fetch handler is invoked when this worker receives a HTTP(S) request
  // and should return a Response (optionally wrapped in a Promise)
