If you are using next-on-pages, then you need to use Next Server Routes

You can’t use Pages Functions directly

Im trying to set up a function that simply takes the form data and submits it to the d1 database thats binded to the page. this is the form element:
<form class="form" data-form="" action="functions/formSub" method="POST">

when i submit the form it takes me to the action address instead of just running the function itself. ive added event.preventDefault(); to the handle but that doesnt seem to help. can anyone give me a hand submitting form data to a binded d1 DB via a function?

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/hello.js

_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

/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

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

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.

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"}

{"env":"prod"}

{"env":"prod"} , there's no sub-fetch or database queries going on. The endpoint sets

cache-control: private

cache-control: private

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?

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()

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

context.request

context.request.url

context.request.url

context.request.url to at least exist?

My

JSON.stringify(context)

JSON.stringify(context) look like:

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

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
