I cant find the option to set if functions fail open or closed in the dashboard anymore. Does anyone know where it was moved to?

in your settings run, did you set compatibility flags as :

Ricky U•10/13/24, 11:25 PM

and in root i usually have a file called wrangler.toml
compatibility_date = "2024-09-17"
compatibility_flags = ["nodejs_compat_v2"]

Ricky U•10/13/24, 11:26 PM

then install jsonwebtoken in your root /functions directory,

for me its in the side bar called "workers routes" after you select your pages website.

it is getting very confusing, i hope pages are seperated from all the rest, seems like so many things you cant do if you are using pages, the menu system is still very confusing.

can you send a pic zoomed out more, I still cant locate it

Ricky U•10/14/24, 1:41 AM

without disclosing i cant, there is a search bar, look for worker routes

I understand. Thank you.

Can Worker / Functions be made to send email using a self hosted SMTP server ?
I want to be able to send contact form submission emails for a Pages site.

Burrito•10/15/24, 12:36 PM

How do functions work in terms of modules/bundling? Are your functions in a project effectively bundled into a giant script, and effectively is just the same as workers? Can you use npm packages in functions?

Walshy•10/15/24, 12:37 PM

yes and yes

Burrito•10/15/24, 12:40 PM

How are routing handled at runtime then, does it mean the bundled worker has some built-in routing code?

Walshy•10/15/24, 12:44 PM

yup

Walshy•10/15/24, 12:46 PM

if you look at the build output you can see it or look at the code: https://github.com/cloudflare/workers-sdk/blob/97110195a751dae70128fb892cb2fb86f6d94470/packages/wrangler/src/pages/functions/routes.ts

Burrito•10/15/24, 1:07 PM

I'm wondering if it's better to do my backend as a pages project using functions, or a regular worker

Burrito•10/15/24, 1:10 PM

Routing libraries like Hono do things like generating some special data structure so looking up the route gets faster, but that's irrelevant for workers since IIRC requests will rarely hit the same machine twice, so all those work are just unnecessary overhead.

Walshy•10/15/24, 1:16 PM

they can hit same metals twice but reducing from less than a millisecond to even less than a millisecond is very inconsequential, the rest of your code will be far far slower than routing ever is

Walshy•10/15/24, 1:19 PM

pick what makes more sense for you, hono is great, functions default stuff is great, itty-router is great, lots of things you can use

better to prioritise what makes sense from a dx/usability prospective than worry about micro-optimisations in perf

Burrito•10/15/24, 2:00 PM

I was also thinking about the cost of including library's code which needs to be parsed and run, and well a dependency is a dependency you need to maintain. But I see your point.

Ricky U•10/16/24, 2:02 AM

Are my API functions being scanned?

Im looking out the Real time logs for my pages functions and i see random api calls to endpoints that do not exisit such as:
/api/liferay
/api/users/admin/check
so many other randoms..
and despite not having any functions there, cloudflare returns a 200 OK?
are these cloudflare pings? or what are they?
my guess is that all routes to /api/* are allowed but if function does not exist it should block or not pass through...
any help much appreicated

Ricky U•10/16/24, 2:04 AM

the User-agent seems normal
And the json for the botsManagment shows as :

"botManagement": {

          "verifiedBot": false,

          "score": 99
        }
      }
    },
    "response": {
      "status": 200

    },

Ricky U•10/16/24, 2:05 AM

shouldn't it return a 404 at the very least, or have no response if the route doesn't exisit

Ricky U•10/16/24, 2:19 AM

seems to be coming from : "asOrganization": "Amazon.com",

Isaac McFadyen•10/16/24, 2:33 AM

Check if you have a 404.html. If not then Pages will assume SPA mode and will always serve an index.html even for not found routes.

hey, really quick, can I run page functions in python, or does it have to be with js/ts?

jsk•10/23/24, 10:47 PM

The documentation says this regarding switching from fail close/fail open for a cf function:

jsk•10/23/24, 10:47 PM

jsk•10/23/24, 10:47 PM

There is literally no place inside of a project to change this setting anywhere

jsk•10/23/24, 10:49 PM

I checked workers routes under domains to see if the cloudflare function would be present there for this domain and its not. Not sure if a lot of additional config needs to happen but the cf function is currently up and running

RRicky U for me its in the side bar called "workers routes" after you select your pages w...

jsk•10/25/24, 5:52 PM

I'll follow up on my old message lol -- I can't see fail closed under Workers Routes, or any worker even available under workers routes, because we're using cf functions which technically isn't an isolated worker?

I can add the route but it doesn't matter since worker is none regardless -- theres nothing to match to it and indicate whether to fial open/fail close

Kevin•10/27/24, 4:33 PM

This right here... lotta folks wasting time on optimizing a near-zero to even nearer-zero (every mainstream router) instead of their code that is the real slowdown, haha

Pick the router that fits your vibe/needs and don't look back [until much later]

crossbeau•10/29/24, 12:38 PM

Whats the real difference between workers and functions

Walshy•10/29/24, 12:38 PM

functions are just workers underneath so not much

Walshy•10/29/24, 12:39 PM

functions are just nicely packaged with workers and have their own file based routing system

crossbeau•10/29/24, 12:39 PM

Any limitations of one vs. the other?

Walshy•10/29/24, 12:40 PM

functions usually lags behind a bit in terms of features due to the way it's implemented (e.g. newer bindings will take longer to be supported, logpush and other things like that aren't supported)

Walshy•10/29/24, 12:40 PM

but otherwise, functionally the same limitations

crossbeau•10/29/24, 12:41 PM

Got it, thank you

rob•10/31/24, 3:10 AM

on a pages project using Wrangler, if u put mode = smart it doesnt do anything, h aveto change it in the dashboar

rob•10/31/24, 3:11 AM

but the docs say

placement Placement optional

Specify how Pages Functions should be located to minimize round-trip time. Refer to Smart Placement.

to put it at the highest level like pages_build_output_dir but that throws an error so idk, any ideas?

MrTeddy•11/2/24, 9:02 PM

Hi, I'm trying to build a full-stack application with Pages and Functions. My framework is Angular. I've added a functions folder, and I have a single route currently, however when I send a request to that route it returns the Angular app HTML rather than the expected response.

Any ideas?

"botManagement": { "corporateProxy": false, "verifiedBot": false, "jsDetection": { "passed": false }, "staticResource": false, "detectionIds": {}, "score": 99 } } }, "response": { "status": 200
