I think to call a pages function, u gotta hit the full endpoint, like https://urdomain.com/formsub

When I have Cloudflare page connected via git and 11ty creates this site

$ find _site 
_site
_site/index.html
_site/functions
_site/functions/hello.js

$ find _site 
_site
_site/index.html
_site/functions
_site/functions/hello.js

$ find _site 
_site
_site/index.html
_site/functions
_site/functions/hello.js

$ find _site 
_site
_site/index.html
_site/functions
_site/functions/hello.js

I was expecting the function to be available as

/hello

/hello

... but it's not.

Do the functions need to be in the root of the git repo? or the root of the site?

Is there any way to use a page function as a service binding for another worker

T

tcurdt•2/24/24, 11:43 PM

why are the pages functions not async? https://developers.cloudflare.com/pages/functions/api-reference/

T

tcurdt•2/24/24, 11:57 PM

after some digging it seems async should still work

T

tcurdt•2/24/24, 11:59 PM

but ...

core:user:worker: Uncaught ReferenceError: process is not defined

Nope. The workaround is:

    // ...use variable

Isaac McFadyen•2/25/24, 2:25 AM

Well it depends on how long your initFromEnv takes.

I

Isaac McFadyen•2/25/24, 2:25 AM

Workers are single-threaded so if there's no

await

await

points (no IO) inside initFromEnv then you should be good.

I

Isaac McFadyen•2/25/24, 2:26 AM

If you're

await

await

'ing inside the

initFromEnv

initFromEnv

then there's concurrency issues because Workers may switch the request they're serving on

await

await

points.

T

tcurdt•2/25/24, 3:11 AM

In this very case - no await. But I could imagine there to be one.
That said, I don't think there is ever the need for a full singleton restriction.
This would just be about caching. So I think it should be OK - even then.

alok•2/27/24, 10:50 AM

Hi, I have a BetterStack monitoring job hitting a pages function endpoint which always returns the same data (the code instantiates a few JS classes and then returns

{"env":"prod"}

{"env":"prod"}

, there's no sub-fetch or database queries going on. The endpoint sets

cache-control: private

cache-control: private

. On my BetterStack graph, I'm seeing lots of requests which take ~1 second and even a handful which take ~2 seconds. I switched to paid workers, but don't see any difference in the graph. So a couple questions:

any debugging suggestions for minimizing these latency spikes?
is the performance of workers vs page functions very different? I can migrate from page functions to workers with a little bit of work.
ideally I would like to see numbers more in line with https://www.openstatus.dev/blog/monitoring-latency-cf-workers-fly-koyeb-raylway-render.

My account id is 9be6f6ea52d6a7dffc494c0fe0bc6729 if anyone wants to help look into this. Thanks!

Walshy•2/28/24, 6:33 AM

Complex answer haha. What's the code doing? Are you fetching external resources?
They're the same. Functions is just Workers
That benchmark is measuring time to invoke and start. The code is very simple and returns right away. Adding more complexity (e.g. fetching external resources) will understandably add more time before a response can be returned

We'd really need to understand the code to understand where this can come from. You talked about it a bit but we'd really need to know more.

Also question, do you have something like Smart Placement enabled?

A

alok•2/28/24, 8:39 AM

The code isn't doing anything. It's instantiating two classes I use everywhere (the constructors just set a bunch of properties). Then returns with
```
Response.json()
```
```
Response.json()
```

alok•2/28/24, 8:42 AM

not all my requests need the D1 binding. I guess I should split things into two workers? Or two distinct pages projects.

  The provided entry-point path, "functions", points to a directory, rather than a file.

When I run it using

my script works perfectly.

This also means, that my build logs show the following error because it can't find the index.js. How do I fix this?

Hi, is it not possible to get query parameters via a Pages Function?

I am wanting to do a login callback via a Pages Function, which returns a token as a query parameter, however, my

context.request

context.request

object is completely empty?

I would have expected

context.request.url

context.request.url

to at least exist?

My

JSON.stringify(context)

JSON.stringify(context)

look like:

{
  "request": {},
  "functionPath": "/api/auth-callback",
  "params": {},
  "data": {},
  "env": {
    "ASSETS": {}
  }
}

{
  "request": {},
  "functionPath": "/api/auth-callback",
  "params": {},
  "data": {},
  "env": {
    "ASSETS": {}
  }
}

{
  "request": {},

fwiw, JSON.stringify is the culprit here

Even on browsers, you can't stringify the Web API objects

Lambo•2/29/24, 7:23 PM

Interesting, good to know

K

kian•2/29/24, 7:23 PM

console.log is better, but still has some issues - util.inspect from the nodejs_compat compatibility flag is much better

Still can't figure it out. I tried a few different strategies to pin down the issue:

```
wrangler pages functions build ...
```
```
wrangler pages functions build ...
```
then run the compiled file via plain
```
wrangler dev
```
```
wrangler dev
```
in local and remote mode and
```
wrangler deploy
```
```
wrangler deploy
```
All worked fine. Also the compiled script was 700kb minified gzipped.
`Tried reverting all the packages to the last known good packages. this didn't work too. Then I tried deleting some old deployments (maybe I have too many preview deployments??) Somehow it worked. Then I switched back to the latest main branch and it didn't work again.
Any other ideas of things I should check?

I think was a file size issue! This is a Remix Vite app. I turned on

build.minify

build.minify

in my vite config and it deployed. I guess I am closer to the 1mb limit than I thought.

Does

wrangler pages deploy

wrangler pages deploy

minify by default?

Feature request: Could
```
wrangler pages deploy
```
```
wrangler pages deploy
```
show the uploaded size of the worker bundle? (Right now it just shows
```
Uploading Functions bundle
```
```
Uploading Functions bundle
```
) (Edit I found an existing feature request)
I guess I will write myself a script to print my worker bundle script size and gzipped size to help keep better track of this in the future.

Hey, I want to parse some HTML which I am scraping via a Pages Function. My initial thinking was

HTMLRewriter

HTMLRewriter

would be the way to do this, but I'm not sure now I'm actually trying to implement it.

Essentially, if I was querying on the client I would have something like:

const items = Array.from(parsedData.querySelectorAll("#example-parent")).map(parent => {
  const thingOne = parent.querySelector("#example-thing-one").getAttribute("content")
  const thingTwo = parent.querySelector("#example-thing-two").getAttribute("content");

  return { thingOne, thingTwo }
});

const items = Array.from(parsedData.querySelectorAll("#example-parent")).map(parent => {
  const thingOne = parent.querySelector("#example-thing-one").getAttribute("content")
  const thingTwo = parent.querySelector("#example-thing-two").getAttribute("content");

  return { thingOne, thingTwo }
});

const items = Array.from(parsedData.querySelectorAll("#example-parent")).map(parent => {
  const thingOne = parent.querySelector("#example-thing-one").getAttribute("content")
  const thingTwo = parent.querySelector("#example-thing-two").getAttribute("content");

  return { thingOne, thingTwo }
});

const items = Array.from(parsedData.querySelectorAll("#example-parent")).map(parent => {
  const thingOne = parent.querySelector("#example-thing-one").getAttribute("content")
  const thingTwo = parent.querySelector("#example-thing-two").getAttribute("content");

  return { thingOne, thingTwo }
});

If I try implement something similar via

HTMLRewriter

HTMLRewriter

I end up with:

class ExampleElementHandler implements HTMLRewriterElementContentHandlers{
    element(element: Element): void {
        element.??? // how do I access the children
    }
}

const parsedData = new HTMLRewriter()
  .on("#example-paret", new ExampleElementHandler())
  .transform(res);

class ExampleElementHandler implements HTMLRewriterElementContentHandlers{
    element(element: Element): void {
        element.??? // how do I access the children
    }
}

const parsedData = new HTMLRewriter()
  .on("#example-paret", new ExampleElementHandler())
  .transform(res);

class ExampleElementHandler implements HTMLRewriterElementContentHandlers{
    element(element: Element): void {
        element.??? // how do I access the children
    }
}

const parsedData = new HTMLRewriter()
  .on("#example-paret", new ExampleElementHandler())
  .transform(res);

class ExampleElementHandler implements HTMLRewriterElementContentHandlers{
    element(element: Element): void {
        element.??? // how do I access the children
    }
}

const parsedData = new HTMLRewriter()
  .on("#example-paret", new ExampleElementHandler())
  .transform(res);

However, because

Element

Element

Element

Element doesn't (as far as I can tell) implement any methods to get the children elements, I'm not sure how I should progress.

Any pointers are greatly appreciated.
