What's the best way to send mail from a Pages instance?
ICreate a function which you can send a POST to that calls an email API like SendGrid to send the email for you. You need the function so that you can use secrets/api keys (passed in through environment variables) that should not be revealed in the frontend.
IIf this function is for something like a contact form that is exposed to the public (you don't have to log in to use it), then take extra precautions to prevent abuse. Add CSRF prevention and rate limiting.
IEven though it's a single endpoint, you might want to consider using a microframework like Hono since it has built in middleware you can apply that does CORS, CSRF, and there's a 3rd party rate limiter middleware as well.
MHey folks, how can it be that one of my functions (it's proxying a websocket request) sometimes produces exceptions which the log stream doesn't show? Like I would have expected the logs or the exceptions array to contain something...
TI'll look into this! Thank you
Ino problem. I've got quite a bit of experience with Hono in Page functions so feel free to ask me questions about it here.
Mthis is happening hundreds of times per hour, so that's really concerning...
TIsn't there like a request duration limit? Might be related?
JIs there any way to use
I'm not getting the same compatability between Pages Functions and Workers.
"node_compat" within the wrangler.toml?I'm not getting the same compatability between Pages Functions and Workers.
HNot on Pages, no
Jso what can I do? I'm not able to use some libraries that I am able to use on Workers
HPut them in a Worker, then call it with a Service Binding?
JI guess ... but that seems going opposite of the whole Nuxt building for Pages setup
Jthis isn't a feature that can be supported by CF? Seems weird that Functions and Workers isn't 1:1
Inode_compatnodejs_compatI expect that's why there's no target of feature-parody there.
Jthe package I'm having issues with is

II know getting stuck is frustrating, but coming in hot and yelling about it doesn't make anyone want to help you. Outline the problem, what versions of Sveltekit you're using, explain CLEARLY what steps you took and what isn't working, etc. Also, Sveltekit has their own tutorial https://kit.svelte.dev/docs/adapter-cloudflare-workers
HTThis is perhaps too general of a question, but often when I look for docs and info about how to set up and use Pages Functions, I get docs for Workers intead. I know there's a lot of overlap, but it's not clear to me exactly how to adapt info about Workers to apply to Functions. Are there some general guidelines, or docs that discuss this?
HClarifying Question: are you using any kind of framework for your project?
TUsually Hugo, but I have successfully set up and used functions in projects that don't use a framework, too. To be slightly more specific, I've managed to get my functions talking with Stripe checkout and Google scripts, but not Respond or Mimetext.
BDo functions support python? I see the documentation covers javascript and typescript, but I didn't see any mention of python (or I'm blind).
JThey don’t unfortunately, no. https://docs.google.com/spreadsheets/d/1T7j7FZZO7zmkrEegzhMeMtlFPIh-efYGMc7BuenMPWY/htmlview# is a good reference for what works where on Cloudflare’s developer platform
BThanks.
IYou could theoretically transpile python to WASM but that would come with all sorts of limitations on dependencies and such
Fdid you ever figure this out?
IYou can use sentry for page functions. I'm using it with Hono.
IThe above code injects sentry onto the context, so inside your routes you can do
Fhmm, does this auto-capture uncaught exceptions as well?
IIt can catch some that fall through, but you can also add it to an
onError()gotcha. I'm pretty new to hono/CF ecosystem. So a very dumb question:
how did you do this? did you do anything in your
If you're running your application on Cloudflare Workers, set a binding value named SENTRY_DSN, which will be used as the DSN.
how did you do this? did you do anything in your

wrangler.toml.dev.varsI've put it in there and am able to access the url, but I'm unable to access the instance:

Fjk, I got it. thank you!

GitHub
monorepo for Hono third-party middleware/helpers/wrappers - honojs/middleware
Fgot it. yeah, I got the errors firing into sentry. how did you handle source maps by chance?
II didn't. Source maps don't make sense for HTTP errors; either your route returned a success or an error. Any internal errors are probably going to be custom try/catch so you can put a more descriptive explanation of what went wrong.
JDoes anyone know why Access-Control-Allow-Credentials causes an Invalid Header error in Cloudflare Page Functions? 
IHow have you defined the header?
JJust like new Response(null, { status:200, headers: {"Access-Control-Allow-Credentials": "true" })
JWith the standard other CORS headers
JHi, when I use fetch to do sub request, when headers contains
headers.set('Accept', 'application/json');
