just used the MailChannels pages plugin for a simple signup form on my site and it worked flawlessly on the first try. I'm blown away

Quick question, with the MailChannels pages plugin (or any other plugin). Does it have CORS setup in place? Like if a request comes to that plugin from someone (not the page itself), will the request proceed? (I'm looking to make sure that it only works from the contact form and not from curl or postman for example)

It does not. Note too though that CORS is implemented client-side, not server side. As in, you can pass CORS headers to a client, but they can just choose to ignore them.

Hmm, right. Any ideas how to secure the endpoint? Either on the plugin or in a worker standalone.

Only send an email when some other verification is sent? But also, the plugin serves more as an example, and you should probably write your own instead.

I already have a worker that I use for the bellow. I have a contact form, client puts his mail, form submits to my email, and also sends a copy to the mail the client put. The problem here is, anyone can start sending requests to the workers endpoint, and putting anyone's email, and writing whatever he wants in the form. Which can "impersonate" my mail. Tho the same can be done from the form, but I can have some time delay there I guess.

Hello! I am trying to publish a Pages project from Github, that uses a library called "@xata.io/client". It works locally, but when I publish to Cloudflare the deployment fails with the error "Could not resolve @xata.io/client". Does that mean I can't use it, or am I missing something?

Nevermind, I think I figured it out. I added "npm run build" as a build command in the Pages settings, and then "build: npm install @xata.io/client" as a script in package.js. It seems to have worked.

Quick ? - can my Pages project have a function that's run as a cron trigger? I've added the [triggers] section in my wrangler.toml, and I can see a cron log every time it fires - but I can't seem to figure out how I'm supposed to specify my event handler. I have an index.ts inside a functions/api/scheduler/ folder (with both an addEventListener and export default, which call my handler) - but this never seems to get run. If i instead run with

wrangler dev <path to index.ts> --test-scheduled

, it runs - though then of course my pages aren't hosted (as it's not a pages run). Or if my question should be asked elsewhere, that would be helpful to know too

I am trying to use a function to write a file R2, and I can't get any blob-type to work. Here's a very basic repro:

js
const obj = { hello: 'world' };
const blob = new Blob([JSON.stringify(obj, null, 2)], {
        type: 'application/json',
    });
const r2Obj = await ctx.env.PUBLIC_BUCKET.put(uuid(), blob);  // This throws an empty exception

console.log(JSON.stringify(r2Obj, null, 4));

try blob.stream() as the second argument to put

Nice! That works, thanks @kian

Are pages functions different from workers? I'm trying to figure out how to write to a kv namespace from a function but everything I'm finding is for workers/wrangler and I'm curious if I have to switch to that to be able to use kv

nvm, I just found where the bindings settings are. They didn't show up in the page settings until I deployed a function.

They're the same thing just different syntax

It’s very confusing when googling and looking for examples. Do you know of an example of writing to kv from a page function? I failed to find one and do it last night

Do I import ctx? Maybe that’s what I was missing

No,

ctx

is present within the Function handler.

Like

js
export async function onRequest(ctx) {
  await ctx.env.KV.put(“key”, “value”);
  // Do something else
}

oh cool, that wrote something. thanks!

Can I deploy nextjs site with prisma without prisma data proxy to pages function

Currently pages functions has the same pricing and request limit as workers, how does the size limit of workers applies to pages functions? Does every pages function file count as one worker or does cloudflare bundle all pages function files into one worker?

Sorry if it has been asked before, but using Discord search bar and the official docs didn't bring any result

Yes, the limits are the same

All of your Functions files are bundled into 1 Worker

Thanks for the quick answer! Is there any plan to map each function file to separate worker?

Just like Vercel edge functions.

I think this information should be included in the docs.

AFAIK, Edge Functions are also a single deployed Worker
