Hey, I'm curious, how does sending email via Cloudflare works?

MMicorksen Hey, I'm curious, how does sending email via Cloudflare works?

You can't. The only exception is if you use Email Routing, in which case you can only send email to your own (authorized) addresses and only in response to an existing email coming in.

The use-case there is to forward email to yourself or filter email before forwarding it on.

And can't I use Gmail Relay with CF Workers? Because I'm using CF Workers as a tiny webhook system and would like to use Trustpilot to send invites when someone closes a ticket (can't use their API)

You can send email via an HTTP API through another provider, but you can't send SMTP via Cloudflare Workers sadly, nope.

I

Isaac McFadyen•10/6/24, 6:35 PM

Also just as an addendum in case you're looking online: you might see some past reference to a partnership between Cloudflare and Mailchannels to send email, but that's since ended and can no longer be used.

Yeah because I would've just trusted Cloudflare Workers IPs on Google Workspace relay at this point but bad idea

M

Maybe I'll try to reach out to Trustpilot to see if they can allow me to use that feature (it's normally paid)

How are _header files generated with Framework deploy create scripts? I'm using Vue / Nuxt for example, and it's generating this _header file, but I'm not sure how to customize it other than building, then modifying the _header file in dist/ after the fact.

Is there a proper way to hook into that process to add custom headers? Custom headers also don't seem to be actually working this way, I can't get custom headers to show up at all on the pages endpoint. I tried to add x-frame-options and content-security-policy in all manner of ways and it shows up in the dashboard for headers for that deployment, but they don't show on the request in dev tools network for example, so aren't being respected.

those headers only affect static files and not dynamic functions requests, it would be better to add the headers in the code for the functions however that's done in the framework

B

Biggee•10/7/24, 3:47 AM

Thanks, I thought pages were workers basically, and the headers are showing here for example on the page deployment. Do these headers not apply to the actual routed request?

B

This is probably more of a pages question

Biggee•10/7/24, 4:02 AM

I see what you're saying now, I got it to work by modifying the framework responses. I thought since it was served via cloudflare, I needed to modify headers on the CF side more or less and that _headers was how that should be controlled. I'm not doing SSR, so that was a bit confusing, but even still, it's managed by the framework routing. Thanks for your insight

Ashley•10/7/24, 9:51 AM

That’s fine, then select hello world example, then there should be an option for “Worker with Assets”

A

ArmoredCavalry•10/7/24, 1:57 PM

I see that for Service Bindings for a function call to Worker B from the parent (Worker A) I must "await" the function to prevent it being terminated early. Does this mean there's no way to execute async code within Worker B, which Worker A doesn't have to wait for completion of before returning a response? Specifically I'd like to make a secondary API call / fetch out within Worker B that should be async.

D Trombett•10/7/24, 2:06 PM

did you try using

context.waitUntil()

DD Trombett did you try using `context.waitUntil()`?

A

ArmoredCavalry•10/7/24, 2:22 PM

Doh, apparently it is too early in the morning for me... for some reason I was thinking that wouldn't apply for service bindings (no clue why), will give it a try!

D

D Trombett•10/7/24, 2:38 PM

You're welcome! I do not know either if it'll work with bindings but that's the only solution that I could think of ahahah

The current limit for static assets in workers is the same as pages-- 20k files, and 25 MiB in total assets size. I have not heard of any plans to bump this limit as of present

Was looking for a way to set a timeout on fetch requests from workers, I saw this reply mentioning 100s, but if you are enterprise and want a lower timeout, say 30s, can this be set on the request or does it require account level configuration?

W

Walshy•10/7/24, 8:34 PM

You can set a lower timeout with AbortSignal - https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal#aborting_a_fetch_with_timeout_or_explicit_abort

What is the cloudflare API route that can give me these results for a specific worker?

https://developers.cloudflare.com/api/operations/worker-routes-list-routes

Is inside "Worker Routes" but only returns me routes for a specific zone, but a worker route can be configured for more than one zone.

if I wanted to constantly listen to a websocket and save that data to KV, would that be a worker or no? Basically it would always be listening to stock market data.

should workers be active for that long? or do I want to use something else for this?

Hey guys does anyone know why building a nuxt 3 app in might take more than 5+ minutes 95% of times? Its too long and if you want to revert it if something went wrong takes too long and we have problems.. is there a way to mirror and apply the latest working branch immediately if something wrong happens until the other branched is fixed?

I have a pages project I'm trying to bind a service binding to. The binding is added, but I get a runtime error trying to call my RPC function.

Should I expect to see my pages project in the service binding worker's "Trigger Events" section? I only see another worker that is bound, not my pages project.
