Now, after a week of driver hacking, I'm just sad that I can't get Hypervisor working for my Pages app. However I can use my own Pooler service for now, but it'll have to be a single location while I wait.

is there an alternative to file I/O for nodejs projects?

GetPsyched•10/8/23, 1:29 PM

My project is in SvelteKit and I use a lib that, unfortunately, only accepts input as a file path and outputs to a file.

GetPsyched•10/8/23, 1:30 PM

I use the

node:fs

node:fs

library as of right now. is there any alternative that can work on Functions?

Hello, I’m Allie!•10/8/23, 2:06 PM

Input as a File object, or a file path?

GetPsyched•10/8/23, 2:15 PM

path

GetPsyched•10/8/23, 2:15 PM

if it were an object, I wouldn't need to do file I/O haha

GetPsyched•10/8/23, 2:15 PM

Oh wait nvm I see wym

GGetPsyched path

Hello, I’m Allie!•10/8/23, 2:16 PM

Yeah, then short of trying to rewrite all of the fs calls to R2/KV/whatever, there isn't much you can do

GetPsyched•10/8/23, 2:16 PM

Oh I can work with R2

GetPsyched•10/8/23, 2:16 PM

but that'll butcher local testing

GetPsyched•10/8/23, 2:16 PM

whenever I test it will push to R2 haha

GetPsyched•10/8/23, 2:17 PM

besides, that's a ton of overhead, isn't it? since I'm almost instantly using the outputted files

I'm trying to eliminate each roadblock from hosting on Pages one at a time

AFAIK

should work on Pages

GetPsyched•10/8/23, 2:26 PM

it brings its own binary

zegevlier•10/8/23, 2:30 PM

Just like workers, pages functions don't run on Node, and they don't have access to the operating system. You can't run binaries on pages functions. You could, however, run stuff like that during build

Zzegevlier Just like workers, pages functions don't run on Node, and they don't have access...

zegevlier•10/8/23, 2:30 PM

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

Zzegevlier Just like workers, pages functions don't run on Node, and they don't have access...

GetPsyched•10/8/23, 2:33 PM

Fair enough.

GetPsyched•10/8/23, 2:33 PM

I can run them on normal Pages though, right?

GetPsyched•10/8/23, 2:34 PM

referring to binaries specifically

GetPsyched•10/8/23, 2:34 PM

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

GGetPsyched I can run them on normal Pages though, right?

zegevlier•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.

GetPsyched•10/8/23, 3:19 PM

Thanks for the detailed explanation!

GetPsyched•10/8/23, 3:19 PM

Neither of these can run node

this refers to functions and workers, right?

zegevlier•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...

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)

zegevlier•10/8/23, 4:15 PM

Yes.

GetPsyched•10/8/23, 4:20 PM

Unfortunate.

GetPsyched•10/8/23, 6:05 PM

is there no other local file I/O alternative?

GetPsyched•10/8/23, 6:05 PM

I'm guessing no

GGetPsyched is there no other _local_ file I/O alternative?

Hello, I’m Allie!•10/8/23, 6:39 PM

Nothing other than storing everything as a string/blob

GetPsyched•10/8/23, 6:40 PM

Gotcha.

I have configured a build that yields a

functions/[[path]].js

and a

functions/[[path]].js.map

functions/[[path]].js.map

file. Do I expect stack traces to automatically use the sourcemap? Cause the logs are unreadable for me when I connect to a live function and an error happens.

KKris Does anyone understand the Pages Functions framework enough to understand what m...

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

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.

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

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)

actually it's just my DNS server that is not aware of the domain

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);

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.

kian•10/9/23, 4:18 PM

The URL needs to be absolute.

kian•10/9/23, 4:18 PM

(i.e have a hostname)
