While this isn't directly possible using only Workers, it is definitely possible if you use something like https://sendgrid.com/

Is it possible to install any type of libraries when using functions?

I would imagine it is NodeJS under the hood. And there are multiple ways to send emails in NodeJS

e.g.

nodemailer

Functions are "functionally" Workers on top of Pages. So, if you can use it on Workers, it should work with Functions.

So

nodemailer

would not work, or at least not without serious tooling/shimming/feature loss.

Functions/Workers isn't NodeJS under the hood-- they're a special kind of V8 service worker. This gives them excellent performance at the cost of incompatibility with libraries that expect a node environment.

My app sends email by making a

fetch

POST request to the Mailgun API

Yeah, it's not Node.JS as Toggle says. Also they don't proxy TCP, only HTTP, so you need to use an HTTP email API like Sendgrid or Mailgun or similar.

Are websockets supported in pages functions ? Essentially I'd like to connect through to a Durable Object via the function's worker. Despite quite a bit of searching I've not seen any mention or examples. My assumption is that I'd need to modify the _workers.js. Obiously I could connect to a worker on a separate domain that connects through to the DO but having it all in one place in the pages app would be sweet.

So WebSocketsw are supported in Workers yeah, but I'm not sure about Functions because they are currently running an older version of the Workers runtime.

(And there's no way to upgrade, yet)

Ah, ok. thx. I may give it a go to see if I can upgrade the connection, but I'll assume it needs to be separate. I guess that custom routes for workers can't be overlaid over the pages domain either.

Hi

My cloudflare pages function in advanced mode

works under miniflare

but gives 500 error code when deployed

I tried putting it in a global try catch function

And returning the error in the body

but it is not working

What should I do to debug this issue?

Here is the code: https://www.pastery.net/ykvhsx/

It's a simple SSR + static assets handler

Any suggestions anyone?

Short of opening a CF support request, I have ran out of ideas on how to debug this

Because CloudFlare doesn't provide logs for functions

@Isaac McFadyen | YYZ01 🙏

I'm not sure it's .ts compiled when you use a

_worker.js

Ah sorry, i have a separate build script

Lemme post the repo
