Anyone managed to run nestjs in a worker ?

CJZh•2/26/24, 8:53 PM

hi, just want to confirm that the AI gateway helps to collect more data, but you can build a worker connecting to Openai, WITHOUT using AI gateway, is that correct?

kian•2/26/24, 8:54 PM

Yes

CJZh•2/26/24, 8:55 PM

Thank you! And I think the AI gateway also does not improve any network performance, right?

kian•2/26/24, 8:56 PM

You can use it to cache results

kian•2/26/24, 8:57 PM

It's likely a tiny bit slower if it isn't cached as there's the additional hop, I don't know if it uses CF's backbone.

CJZh•2/26/24, 8:58 PM

I see, I am new to this I think I will skip the gateway to keep it simple for now. Thanks!

After a few days and a few escalations, I've recieved an answer.

The mailfrommailfrom object was apparently an internal API that was not intended to be public. However, since it was documented, they told me how to use it.

- Do not set the top level fromfrom field. Do this inside the personalizationspersonalizations object instead.
- Set the mailfrommailfrom in the top level.

From then, it should work. Tested and it seems to be working.

So to clear up, from this screenshot, - the solution is just to move the very first "from:" here, with '${from}@${domain.domain}', down under "personalizations:"?

when a worker throws an exception https://developers.cloudflare.com/workers/observability/errors/#error-pages-generated-by-workers what is the http status code returned to the client? I am looking through analytics for my zone and I don't see any 1XXX errors.

kian•2/27/24, 1:35 AM

500

Kkian 500

Justintime•2/27/24, 1:35 AM

thanks!

Justintime•2/27/24, 1:48 AM

@kian and those 500s would show in zone analytics?

I personally feel it is better that way, as the header "From:From:" is technically a "personalization" just like other headers such as e.g. "To:To:", "Subject:Subject:", and so forth.

I'm actually starting to wonder if the outer from:from:/mailfrom:mailfrom: are technically synonyms of each other, e.g. both being the mailfrom:mailfrom:, as that would somehow make better sense.

Interesting fact is also no matter if it is from:from:/mailfrom:mailfrom: in the outer area, or the from:from: under personalizations:personalizations:, they all seem to indicate the optional friendly name:name: string, which the actual SMTP MAIL FROM (mailfrom:mailfrom:) / Envelope From / Bounce address doesn't have.

That friendly name:name: only makes sense for the bcc:bcc:/cc:cc:/from:from:/reply_to:reply_to:/to:to: within personalizations:personalizations:, if you ask me.

And with bcc:bcc:, it depends quite much on how their system is handling the bcc:bcc: though.

DarkDeviL•2/27/24, 3:55 AM

I would also say that having headers:headers:, reply_to:reply_to: and subject:subject: both in the outer area, as well as the inner personalizations:personalizations: area makes absolutely no sense either.

DDarkDeviL I personally feel it is better that way, as the header "`From:`" is technically ...

addison•2/27/24, 3:56 AM

I did actually test and the outer from isn't an alias of mailfrom, it just does the same thing as the inner from

addison•2/27/24, 3:56 AM

there's definitely a lot of weird decisions made

DarkDeviL•2/27/24, 4:05 AM

Thanks for also testing that!

DarkDeviL•2/27/24, 4:06 AM

to that weird decision part.

is there a way i can run a worker only once after being deployed?

Mongy•2/27/24, 5:50 AM

i was thinking i could use cron expression to be run on the same date being deployed but i was curious if there might be other methods

MMongy is there a way i can run a worker only once after being deployed?

Hello, I’m Allie!•2/27/24, 6:28 AM

Put a WAF rule on the route that checks for a certain header, then hit that URL?

Hello, I’m Allie!•2/27/24, 6:39 AM

Or validate it in the Worker, then undeploy it afterward

Mongy•2/27/24, 8:03 AM

So Im looking to use github actions to deploy the worker. The worker repo will also contain files to be put into a D1. Was looking to see if I can configure the worker so it just runs one time and i guess in some way shut off. For every new merge to main, it will contain new files to be stored into a D1 which github actions will take over again and fill the database through the worker.

Hello, I’m Allie!•2/27/24, 8:04 AM

For a one-off like that, would it maybe be easier to just call the D1 API directly?

Mongy•2/27/24, 8:04 AM

using wrangler locally

Hello, I’m Allie!•2/27/24, 8:05 AM

No, in the Action

Hello, I’m Allie!•2/27/24, 8:05 AM

You don't even have to use wranglerwrangler. You can make the API calls with your HTTP-client of choice

Mongy•2/27/24, 8:09 AM

Ah, I can do that

Mongy•2/27/24, 8:10 AM

Appreciate it

Has anyone tried to develop gRPC services with workers? Is this possible?

Kuuba_•2/27/24, 11:23 AM

Hello.
Any idea how to fix #No such module "node:buffer". imported from "worker.js" ?

impairedFelon•2/27/24, 12:26 PM

Worker JS Runtime doesn't supports node crypto completely, whats gonna happen if i use Python? Will worker support Python's Crypto libraries?
Also i can't use Firebase Admin SDK with Js Runtime, can i use that in Python?

Mongy•2/27/24, 4:27 PM

hey, after looking through github actions and wrangler actions, I think i may of gotten more confused with this comment hahahaha. The idea im having is to create a worker that will parse a folder within itself containing mdx files to store into a D1. The workflow goal is to push to the main branch of the worker repo with new mdx files where in turn the worker will re-deploy and add them to D1. The mdx files will be pulled from D1 by a client application to display them.

how do I connect my my workers with a github repo?

There's no special integration for it, no CI/CD like Pages has if that's what you're looking for
