Well, I suppose if it's compiled to WASM it might work, but if that's not supported adding that yourself will be extremely tricky

GetPsyched•10/8/23, 2:33 PM

Fair enough.

G

GetPsyched•10/8/23, 2:33 PM

I can run them on normal Pages though, right?

G

GetPsyched•10/8/23, 2:34 PM

AFAIK, I can't run stuff on Node on Pages either

zegevlierOP•10/8/23, 2:47 PM

Pages is a static file host. Pages functions is workers integrated with pages. Neither of these can run node. Pages also has a build process (you push a change to git -> CF builds the project and uploads the results to pages). This runs in a VM where you can do whatever you need, including running node or other binaries. You can't trigger this build process per request.

G

GetPsyched•10/8/23, 3:19 PM

Thanks for the detailed explanation!

G

GetPsyched•10/8/23, 3:19 PM

Neither of these can run node

this refers to functions and workers, right?

Z

zegevlierOP•10/8/23, 3:35 PM

I was referring to the static file hosting part of pages and the pages functions part of pages. But indeed, workers also can't run node or executables

Zzegevlier I was referring to the static file hosting part of pages and the pages functions...

G

GetPsyched•10/8/23, 4:05 PM

So, I can only run node and binaries during the build process and not at runtime? (of Pages, not Functions)

Yes.

I have configured a build that yields a

D

divby0•10/9/23, 1:42 PM

I've seen this and an guess is that only a service like Sentry then uses the map to re-map the stack trace and present the usable stack trace to me? Currently for my small project I am just hitting a webhook that sends the stacktrace as a telegram to me

K

kian•10/9/23, 1:43 PM

Sourcemaps for individual routes aren't useful (iirc) - all of your Functions are bundled later into a single file.

D

divby0•10/9/23, 1:45 PM

I am not following - I have one single [[path]].js function and map. The build artefacts are already just one file (but with mappings to other files that exist during development). Disclaimer, I am inexperienced with buidl maps and infra setup

D

divby0•10/9/23, 1:49 PM

This is how my functions dir looks like (and it should look like that in Cloudflare's CI step as well, so cloudflare should have everything they need to provide the usable stack trace)

I'm stuck on function bindings... I have worker A with a service binding to worker B.

WORKER_A does the following:

    const request = new Request("/", payload);
    const response = await env.WORKER_B.fetch(request);

    const request = new Request("/", payload);
    const response = await env.WORKER_B.fetch(request);

    const request = new Request("/", payload);
    const response = await env.WORKER_B.fetch(request);

    const request = new Request("/", payload);
    const response = await env.WORKER_B.fetch(request);

I get an error:

TypeError: Fetch API cannot load: /

TypeError: Fetch API cannot load: /

All the examples I see show just passing the request that worker A received, but I need to hit a different endpoint on WORKER_B.

K

kian•10/9/23, 4:18 PM

The URL needs to be absolute.

K

kian•10/9/23, 4:18 PM

(i.e have a hostname)

K

kingmesal•10/9/23, 4:20 PM

really? OMG! I though the whole point of that Fetcher was that it was BOUND to the service!

K

kian•10/9/23, 4:21 PM

The hostname doesn't really do anything, it doesn't send it to anywhere but the bound Worker.

K

kian•10/9/23, 4:21 PM

It's the same as Durable Objects - the URL needs to be absolute.

K

kingmesal•10/9/23, 4:49 PM

Okay, well, that did "resolve" my issue... one more question on the topic though ... when I call that worker both the workers log a canceled event, but there was a 200 response:

 "outcome": "canceled",
    "response": {
      "status": 200
    }

 "outcome": "canceled",
    "response": {
      "status": 200

In Cloudflare Workers, I use code like this

if (request.headers.get("Origin") !== "(Website)") { } return new Response('Unauthorized', { status: 403 }); }

I set it to reject all requests except those from my website.

However, using the above method, since the server code is executed even when rejecting requests from other websites, it counts towards the 100,000/day limit on the free plan. This means that a malicious user may intentionally send requests to exceed this limit. How can I prevent this?

Just like workers, pages functions don't run on Node, and they don't have access to the operating sy
