anyone know how to use mongodb in normal js for cloudflare worker

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

AnotherAlex•3/14/24, 3:14 PM

Thanks. They are both empty but I think a downstream service might be affecting compatibility so going to try updating that.

Enduriel•3/14/24, 3:24 PM

Is there a way to measure the ~CPU time of a request when developing locally?

Enduriel•3/14/24, 3:24 PM

I'd like to know the approximate ballpark of w/e I'm doing

You cannot currently connect to MongoDB from a Cloudflare Worker except through the MongoDB Atlas Data API.

Isaac McFadyen•3/14/24, 4:32 PM

You might also be able to use Prisma Accelerate but I haven't tried it.

so the D1 database can only be accessed via workers?

Isaac McFadyen•3/14/24, 5:43 PM

D1 can be accessed either from Workers or using the Cloudflare API (which has rate limits so the Workers binding is better)

ok, so lets say I use cron jobs to slowly sync my database, and then I want to run some script to process the data in the D1 database, what would be the best way to do that?

IMHO that is way too vague for anyone to provide useful direction

Hunter Bertoson•3/14/24, 7:51 PM

I have a worker set up to send emails using the MailChannels Integration. It works great from the console. But when I call it from my localhost to try and send an email. I get a 403 error. Is this not possible? My site is Astro and is deployed on Cloudflare Pages.

Devon•3/14/24, 7:54 PM

when you say localhost are you running the Worker locally? if so that won't work, as the MC integration only allows calls from deployed Workers IPs

Hunter Bertoson•3/14/24, 7:55 PM

I am not. I can try that. I did try it on my deployed site and it still came back with a 403 error though

Devon•3/14/24, 7:57 PM

okay yeah it has to be running deployed in CF env. I just went through getting MC working (using the free setup with Workers). It's sort of a pita;) You did the Domain Lockdown DNS thing, DKIM, SPF, etc...?

Devon•3/14/24, 7:57 PM

and they usually send an error messsage back in the response body that has more info

Hunter Bertoson•3/14/24, 7:58 PM

Yeah. I have the Domain lockdown DNS, DKIM, SPF all that Jazz. If I run it from the Dashboard. It works great. Let me try it again with some better errror handling

Devon•3/14/24, 7:59 PM

I guess I'm not sure I understand Dashboard vs "localhost" for the execution if the Worker is running deployed (not locally).

Hunter Bertoson•3/14/24, 7:59 PM

Here:

Devon•3/14/24, 8:01 PM

ah! okay. but when you trigger the Worker by calling it's endpoint it fails? that IS odd

Hunter Bertoson•3/14/24, 8:09 PM

I figured it out now.

Devon•3/14/24, 8:10 PM

what was it?

Hunter Bertoson•3/14/24, 8:11 PM

Hunter Bertoson•3/14/24, 8:13 PM

I think I want the "cf-worker" Header?

Devon•3/14/24, 8:13 PM

is it being called in a way that would pass the referrer? CORS works off the Origin header (set by browsers when executing AJAX calls). So maybe you just need a CORS implementation?

Hunter Bertoson•3/14/24, 8:14 PM

Not sure. i will take a look when I get back. Got to go some Ref some soccer games. Thanks for the help!

kian•3/14/24, 10:13 PM

Sounds like the dashboard is wrong

JoeDoe•3/15/24, 6:50 AM

Is there any sort of "on exit" or "on close" event callback for workers?

limikael•3/15/24, 7:04 AM

What has happened to the "Triggers" tab?

limikael•3/15/24, 7:04 AM

There used to be a "Triggers" tab, right? To set up a custom domain for the worker... Or am I dreaming?

I have a question regarding the design of worker logics. I frequently encounter situations where I want to extract the logic required by a fetch handler into separate functions. However, as I proceed with the extraction steps, I find myself needing access to the request and environment objects within nested functions. I'm struggling to find a solution for designing these parent-child relationships without having to pass the request, context, and environment objects several levels deep. Is there a solution for this issue?

limikael•3/15/24, 7:33 AM

I would say that passing it down is fine. This is also the same as other platforms, e.g. Node.js. If you don't want to pass down three objects, you could create your own class to wrap request, env and context, and pass down instances of that class.

jepp•3/15/24, 7:48 AM

Good Morning, if I may ask, I have a question regarding a worker prototype I've recently built. Essentially, it functions as a bundled worker serving as a WebSocket server

[yes!]. It listens for incoming parameterized requests, looks up a value in KV, and returns the value via the WebSocket connection. Due to the inherent behavior of bundled workers having a 50 ms lifetime, the WebSocket connection is automatically closed or terminated. This behavior is intentional. I utilize the WebSocket connection to transmit data to the client in a manner that is intended to make data scraping (e.g., via REST) more challenging.

Now, here are my questions: How does a worker, in general, scale concerning WebSockets? Or is this a general inquiry regarding the behavior of bundled workers concerning concurrent connections? I'd like to determine how many parallel WebSocket connections/requests I could potentially serve, both in the free plan and the smallest paid plan initially. Additionally, I don't yet grasp whether it's my responsibility as a developer to spin up the appropriate number of workers myself or if this process is handled automatically by the Cloudflare infrastructure (meaning only one worker needs to be programmed, and the rest occurs automatically).

Hello, I’m Allie!•3/15/24, 7:56 AM

It's not your responsibility to scale, it happens automagically. As for limits for WebSockets, your wallet is the limit.

jepp•3/15/24, 8:14 AM

@HardlyWorkin' let's say I go with the paid plan. It's $0.15/million requests per month. Could those 1 MIO websocket based requests be served also in an hour? Will the infrastructure scale?

Hello, I’m Allie!•3/15/24, 8:16 AM

They could be served in a second, if needs be

Hello, I’m Allie!•3/15/24, 8:16 AM

If you are at that scale, you would probably have a custom pricing agreement, but

jepp•3/15/24, 8:17 AM

@HardlyWorkin' maybe... just scaling in theory. You never know. Realistically I am not expecting it. Just want to assess if the planned infrastructure is feasible

jepp•3/15/24, 8:19 AM

what does it mean in the logs if a bundled worker results into "canceled"? 50 ms cpu time exceeded and worker killed?

Hello, I’m Allie!•3/15/24, 8:20 AM

Cancelled iirc means the client has disconnected before a response was returned
