Send email using Workers with MailChannels

MailChannels has created an email sending service specifically for Cloudflare Workers that removes all the friction associated with sending emails.

Did you go to the link the error said? Should explain what you need there

what are service workers in this context? can I test regular module workers with vitest pool?

Unsmart•5/11/24, 3:08 AM

service workers are the old form of creating workers, module workers are the new form

Unsmart•5/11/24, 3:09 AM

https://developers.cloudflare.com/workers/reference/migrate-to-module-workers/#migrate-from-service-workers-to-es-modules is the migration guide and can show the differences from them

Sadly not a direct solution to your problem, but I would recommend you avoid MailChannels. Cloudflare's continued partnership with them is very disappointing after their security issues and terrible response. See https://canary.discord.com/channels/595317990191398933/779390076219686943/1226529017763463219 for more details.

how long can a websocket connection be open on free plan

Cloudfare•5/11/24, 11:38 AM

when i create a new file in my javascript worker and deploy it the file is still not saved

It doesn't save the new javascript file

I'm thinking about migrating a Nuxt application from Vercel to CF pages, but I'm curious if I'll be able to use the cache JavaScript api on the Nuxt server side code?

To be clear, I'm talking about this: https://developers.cloudflare.com/workers/runtime-apis/cache/

clearly works within vanilla workers just wondering what the limitations are with SSR frameworks like Nuxt on pages

Unsmart•5/11/24, 7:59 PM

you can use cache, pages ssr functions are just workers

I have a cron task that should add jobs to a queue. In order to avoid a duplicate jobs being added to the queue the next time the cron runs, I need to keep track of which jobs have been triggered. What's the best way to do that? My initial thought was KV, but I don't think it has any support for something like a transaction.. and neither does D1?

johtso•5/12/24, 12:34 AM

The enqueuing and the storing of the "this job has been enqueued" record needs to be atomic

matt•5/12/24, 4:17 AM

with the new RPC calling, should you still have zod schemas passing the incoming parameters?

Unsmart•5/12/24, 4:20 AM

I mean you can if you want. You didnt even need zod schema when you didnt have RPC its use is mostly do you trust that you actually sent the correct data format or do you want to double check it. I personally never used it because I trusted types

matt•5/12/24, 4:23 AM

how were you able to avoid using it pre-RPC? e.g. let's say the payload is in the body, and you do let body = await req.json()let body = await req.json() then the typeof body would be "unknown"

Unsmart•5/12/24, 4:23 AM

as <type>

matt•5/12/24, 4:24 AM

ah ok, i guess as long as you were wiring up your calls correctly then the parser isn't needed

my thoughts are more along the lines of deploying new versions of the worker, what if you change the payload? you're going to probably start getting some cryptic errors without a front-loaded parser

GirlRacer•5/12/24, 8:08 AM

Hi, quick question
If i install a package such as aws-sdk/client-s3aws-sdk/client-s3 in a typescript worker, can i expect it to just work as normal in a cloudflare worker?
Currently I cannot see any logs or output when trying to use it

IIsaac McFadyen I don't think there's a limit.

wow awesome

florent•5/12/24, 1:32 PM

Is it viable to use only CF workers for the backend of my mobile app? I can't find any drawbacks some maybe someone could share some experiences. I would greatly appreciate that

WWai #NeyiSevsekKapatılıyor wow awesome

Isaac McFadyen•5/12/24, 2:57 PM

So there's not, but there is this: https://developers.cloudflare.com/network/websockets/#technical-note

Isaac McFadyen•5/12/24, 2:58 PM

When Cloudflare releases new code to its global network, we may restart servers, which terminates WebSockets connections.

Isaac McFadyen•5/12/24, 2:58 PM

So you definitely want to implement retries of some sort on the client.

Walshy•5/12/24, 2:58 PM

Hey, is it posible to change the MOTD of a Minecraft-Server whit a cloudflare worker. So you could do like that for every subdomain, for example *.example.com the Motd is Hey this is a Minecraft-Server of example.com?

Cyb3r-Jak3•5/12/24, 7:14 PM

I would doubt it. I don't know the minecraft protocol but I would imagine they do it over TCP which workers don't have inbound for

But do you maybe know a other way? Like not with workers?

PPrivt But do you maybe know a other way? Like not with workers?

Cyb3r-Jak3•5/12/24, 7:49 PM

No. My guess is you'd have to run something in front of the minecraft server to intercept and change the request.

Ok thx for your help.

Martial•5/13/24, 12:23 AM

I just had a terrible DX today. I need to share it.
Cloudflare pages + workers is really sexy. I am currently building a Nuxt3 app on it and was enjoying it so far, even if I known I am using fairly new techs so wasn't expecting to encounter no obstacles. The thing is, I just wanted to stream some text (from open ai models) from my worker, and once I made it work on my dev server, I checked a preview with

wrangler pages dev

wrangler pages dev

: it was not streaming, the response from the open ai APi was outputted all at once. I spent a lot of time, either here or online in the docs, just to realize it was working perfectly fine once deployed! only it is not working when previewing! (Image I found lately in the AI space of the doc) Damned! And I love to think that it's nice to be able to run the app locally in an env close to the production one, a bit like starting a docker container. But it cost me a lot today.

rob•5/13/24, 3:47 AM

https://developers.cloudflare.com/workers/playground/ on this playground is it actually deploying the worker or is it emulating it all like miniflare3 but running in the browser only? So it's like compiled in browser ?
