does middleware count towards your functions quota?

H

heftymouseOP•3/25/24, 4:39 PM

additionally, can i only run middleware on some static files? i'd like it to run before my actual pages get served but not static assets

H

heftymouseOP•3/25/24, 4:41 PM

the documentation just mentions

functions/_middleware.ts

functions/_middleware.ts

functions/_middleware.ts

functions/_middleware.ts for 'all requests, including in front of static files', can't tell if there's any granularity for static files

I can't seem to figure out from the documentation, but is it possible to prevent a Pages Function from being called from anywhere other than the Page itself?

Not really. While you can use CORS to prevent other websites from calling your Functions, that only works in browsers that respect CORS. Not to mention tools like

Dally•3/31/24, 3:05 PM

Hey guys, quick question. I'm using Pages to deploy my site in advanced mode, that is with _worker.js file. Currently my framework builds the site with _worker.js directory, meaning that it is not bundled. Does Pages deployment do any bundling before the worker is deployed, or do I have to bundle it myself? Thanks!

D

Dally•3/31/24, 3:05 PM

I googled and only found this: https://community.cloudflare.com/t/refactor-a-worker-to-a-pages-function-problem/536838 when one user mentions this, so I want to be just sure

When using advanced mode, you need to bundle the worker—Cloudflare Pages build system doesn’t handle the bundling (if I recall correctly.)

D

Dally•3/31/24, 3:22 PM

So I may have confirmed this myself, there is no bundling step done automatically. Please correct me if i'm wrong.

I have a service worker and I'm getting in a bit of a muddle trying to pass it some data. Hopefully just being blind but can anyone just point out what I'm missing. Context (or request when destructured out) doesn't contain the data I'm trying to send

 //service worker
     const body = JSON.stringify({
        eventData: event.data,
        shown: true,

I am a little confused about pages function, is it just like clouldflare workers and can be fetched?
so

functions/hello.ts

functions/hello.ts

can be fetched like

fetch('/hello')

fetch('/hello')

in my fullstack app?
Because when I do that in my remix app and try running it locally using wrangler, I can access directly via

http://127.0.0.1:8787/hello

http://127.0.0.1:8787/hello

but fetching it gives an error

Invalid URL string. checkURL

so in your fetch do “http://127.0.0.1:8787/hello” as the url

R

Ruxorly•4/2/24, 2:23 PM

although i’m not well versed in remix, they could have a check to see if it’s a valid full url

R

Ruxorly•4/2/24, 2:24 PM

you might be able to use an environment variable to see if it’s running on prod and if it is, use that base url, otherwise use 127.0.0.1

V

vimo•4/2/24, 2:30 PM

You are not wrong to assume that but relative urls in Remix works.
Yes, I guess for now I will use a local env to concatenate it with the cf pages endpoint in my fetch calls. Will figure it out later when deploying if theres a better way or just if local concatenate else relative.
I hope relative url on deployment works.
Thanks for the help and env suggestion. Really appreciate it.

V

vimo•4/3/24, 9:27 AM

Are pages functions by default CORS protected? Since the function route works like an endpoint, do I have to worry about CORS protection?
Edit: Ah I see https://developers.cloudflare.com/pages/functions/examples/cors-headers/

Hey there!

Using Cloudflare pages functions, local building works great.

Everything compile with

wrangler pages dev  dist/

wrangler pages dev  dist/

. Same using

wrangler pages functions build

wrangler pages functions build

. This last says

Compiled Worker successfully.

If I compile locally and deploy with the next command, again the app is compiled and deployed with success :

wrangler pages deploy  dist/ --project-name my-project

wrangler pages deploy  dist/ --project-name my-project

.

However, if a page build is triggered on Cloudflare based on git push, then the build fails with errors like the following:

I don't believe you can, and I don't think it will be coming. Pages relies on bundling your Functions into one big Worker at deploy time, which wouldn't really work with some being Python and some not - plus they inject custom code which is written in JS, which also wouldn't really work.

IEatBeans•4/8/24, 2:57 AM

I see that pages now supports a wrangler.toml. This is great, but what happens if you already have one for workers in the same project? I am using pages functions primarily, but workers for a few cron tasks. Do I need to move all the workers stuff into a subrepo, or can they both share a toml file?

Seeing a 401 error in your console during a Turnstile security check?
You can safely ignore the error, it's requesting a PAT but your device/browser does not support PATs yet, so you see the error.
