Nope.

kianOP•3/12/24, 5:03 AM

You'd need to check the CF-WorkerCF-Worker request header in order to restrict traffic to only your Workers.

Kkian Nope.

Hello everyone, I've got a problem regarding service bindings. I've already posted a question in workers-help but didn't got any help yet and I don't know what I'm doing wrong. workers-and-pages-helpNot able to parse request body when using service bindings

UUnsmart Also way better because it doesnt rely on jwts like most if not all auth provide...

sathoro•3/12/24, 8:33 AM

we do it immediately by setting a flag on the user object that we load in on every request anyways. we set the flag on events like the user changing their password. zero overhead (since we load the user information from a DO anyways to check usage, permissions, etc), and invalidates existing sessions immediately even when using JWTs

sathoro•3/12/24, 8:34 AM

this is with Supabase auth. and we don't sync anything, we just cache the JWT result in a DO. its super nice

New to workers and I'm trying to deploy a Hono app but I'm getting

import * as Bun from 'bun';
You can mark the path "bun" as external to exclude it from the bundle, which will remove this error.

I added node_compat = true to wrangler.toml and it removed some of the other errors but can't find how to mark this as external.

Unsmart•3/12/24, 5:15 PM

You cannot use the bun runtime on workers. I dont think you can really even import bun like that even if you are using the bun runtime

dolarshop•3/12/24, 5:20 PM

It works but im using it for const hash = await Bun.password.verify(password etc..)

dolarshop•3/12/24, 5:20 PM

but I guess i can remove it and use bcrypt package

dolarshop•3/12/24, 5:27 PM

I have other packages that throws error and it suggested to do it. Is there a better way to handle imports?

dolarshop•3/12/24, 5:35 PM

I have a pretty simple setup

Original message was deleted

dolarshop•3/12/24, 5:49 PM

thanks, i'll try. The app is pretty bare bone. I feel i'm missing something very simple to make this work on workers

Devon•3/12/24, 5:55 PM

just be aware of the impact of using a hashing system (bcrypt) which is designed to be time and CPU intensive, on a platform that bills you for CPU time:)

Advany•3/12/24, 7:18 PM

I am using a worker in zone1 that gets data from zone2. Both zones are in different accounts.

The traffic from zone.source1 to zone.destination is reaching a point that its hitting the rate limiter of zone.destination

If I split the traffic within one account between two workers. One in zone.source1 and zone.source2. Will that fix the rate limiting happening in zone.destination?

Advany•3/12/24, 7:19 PM

And how can the owners of zone.destination increase the rate limit of my zone.source1?

Brandon | Cloudflare TSE•3/12/24, 9:28 PM

depends if you're hitting the global api rate limit, or, if you're making http requests, the destination zone might have a rate limiting rule set.

Brandon | Cloudflare TSE•3/12/24, 9:31 PM

Separate Workers-related request... I learned about resolveOverrideresolveOverride today, to keep a Host header intact while changing the resolved origin address.

Is it possible to do the reverse? Keep the origin intact but change the Host header?

ivanfvj•3/12/24, 10:33 PM

Is Cloudflare having issues with Cloudflare Workers? I have been experiencing a lot of different problems since this morning.
I've added this ticket to the #workers-help channel

workers-and-pages-helpSudden appearance of CPU time limit

I''ve been trying to deploy a worker application using wrangler and the Cloudflare Dashboard and is not getting updated on the custom domain

ivanfvj•3/12/24, 10:34 PM

I'm having these errors in 2 different Cloudflare accounts. My work Cloudflare account and my Personal Projects Cloudflare Account

Unsmart•3/12/24, 10:43 PM

Just esclated this for you @ivanfvj

Unsmart•3/12/24, 10:52 PM

To clarify when you deploy via wrangler do you get any errors? I think the error shown on the dash is unrelated as I get that as well but deploys work perfectly fine. @ivanfvj

ivanfvj•3/12/24, 11:59 PM

Yes I do, I have found and applied a solution that was moving an import inside the cloudflare workers handler, so it reduced the startup time. Reference example here: https://github.com/cloudflare/workers-sdk/issues/3096#issuecomment-1560883961
I am using apollo server on cloudflare workers with this library "@as-integrations/cloudflare-workers": "^0.2.0".

But what I found weird is that the dashboard didn't work either. Also, the deployment was delayed, and even changing to a different network didn't work.
I am testing it now and seems like it's working again, and the last deployment is now using the updated environment variables

Did Cloudflare change some limits?

hi, I have a question for anyone who might use scheduled handlers in workers with cron triggers. In this example, what happens?

export default {
  async scheduled(event, env, ctx) {
    ctx.waitUntil(Promise.reject('oh no'));
  },
};

export default {
  async scheduled(event, env, ctx) {
    ctx.waitUntil(Promise.reject('oh no'));
  },
};

I've checked the docs for waitUntil()waitUntil() , scheduled handlers for workers, and for cron triggers, but none seem to mention what happens in an error case.

dclarke•3/13/24, 6:36 AM

I did find a mention for waitUntil()waitUntil() although it does not state if there is any cascading of that rejection to anywhere outside the handler, or what might happen as a result of that. Would they appear in Cron events as a Status of Internal Error?

Advany•3/13/24, 1:20 PM

I am making http requests to the other zone.

Resolve override has to many restrictions.

What do you mean keep the origin intact and change the host header? Thats not allowed with cloudflare right?

andifined.dev•3/13/24, 2:55 PM

What do you think about using globalThis within workers to avoid „prop drilling“ to get request information in nested function calls?

kianOP•3/13/24, 2:57 PM

Ideally you'd use AsyncLocalStorage

Hello - does anyone know of a tutorial on how to connect a worker to a mysql database via argo tunnel?

Chaika•3/13/24, 5:08 PM

there was an old one but it got removed, had to use a hacky old unmaintained patched sql js driver because Cf Tunnels only expose TCP via Websockets

the repo still exists though: https://github.com/cloudflare/worker-template-mysql

DC•3/13/24, 5:15 PM

Thank you. Did this work OK for you? I am guessing that they are probably not maintaining this pending hyperdrive for mysql. However, it seems to have been on the 'future' list for a while.

Chaika•3/13/24, 5:15 PM

I last tried it a very long time ago. One of the big issues with it is no connection pooling like hyperdrive, so have to make a whole new connection on each request, slow

DC•3/13/24, 5:18 PM

Ah OK - thanks for your insights - I wonder if perhaps the worker solution is not quite ready enough. I wonder how others deal with the lack of access to DB's ? KV write latency is too slow for us and D1 does not quite seem to be production ready. I guess it depends on the usecase.

rob•3/13/24, 6:39 PM

how is everyone.. KV write latency is slow?

rob•3/13/24, 6:39 PM

what about using hyperdrive and raw sql queries?

Rrob how is everyone.. KV write latency is slow?

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
