Which way to do yall use to make http POST requests? I am not that used to nodejs or workes to know some lightweight way to do this

SageSphinx63920•3/11/24, 7:31 PM

Its just a simple POST request with 2 headers and some JSON payload

SageSphinx63920•3/11/24, 7:31 PM

And the return is also just some simple JSON object

Can anyone here somehow use React or Next with Cloudflare Workers?

Unsmart•3/11/24, 7:35 PM

You can use both cloudflare pages makes it easy

Alisson Acioli•3/11/24, 7:36 PM

Yes, I saw here that it is easier with Pages but I wanted to try with Workers. Is there any code compatible with today's workers? I had found "Flareact" but its wrangler settings are very old, the last update in the repository was 3 years ago

Try the fetch API. It's included automatically in Workers but it's not workers-specific, it's the same one as in all modern browsers.

Hello, I’m Allie!•3/11/24, 7:45 PM

Pages is generally Workers + Website hosting stuff. Most of what you can do on Workers, you can also do on Pages

fs0x30•3/11/24, 8:24 PM

Run into a weird problems. My worker is currently doing a fetch() for me to get certain resources. The resource site blocks certain IP ranges which is understandable. When I call my worker's endpoint (deployed) which would then fetch the resource for me from my dev machine, it works. But once I push the code to a server which then calls the worker's endpoint, it is blocked. So does the worker's IP somehow derived from the caller of the worker? Or I am calling from 2 different CF datacenter and one of it is blocked by the site?

fs0x30•3/11/24, 8:27 PM

or is the caller ip being forwarded through HTTP headers

Hello, I’m Allie!•3/11/24, 8:29 PM

No, but Cloudflare uses multiple IP ranges for outbound calls. It may be that only some of them are blocked

Alisson Acioli•3/11/24, 8:32 PM

Are image, js, css files counted as calls on pages or are only visits counted? Imagine that I have a website that has js, css and 3 images. Will it charge like 6 calls? (1 visit + 5 assets?)

fs0x30•3/11/24, 8:32 PM

That's my thought or the caller's IP is being forwarded through the HTTP headers like x-forward and connecting-ip which the resource site is using to also block. I believe the resource API is also on CF

Hello, I’m Allie!•3/11/24, 8:32 PM

If they are not, then those requests would be free

HHello, I’m Allie!It will only be charged if your requests are served by Functions

Alisson Acioli•3/11/24, 8:34 PM

For example, I deployed NextJS hello world: https://baf257f6.my-next-app-qpn.pages.dev/

In this call it is loading css, js and some images. For each user visit to pages, I would be charged as 1 request and not per call including these assets?

fs0x30•3/11/24, 8:54 PM

Yea you're wrong. I checked and the IP of both my server and my dev is the same outbound ip but the Connecting-ip/x-forward forward my real ip address to the site

fs0x30•3/11/24, 8:54 PM

I wonder if there is a way to not do that

fs0x30•3/11/24, 8:56 PM

very interesting mechanic

Nicolas•3/11/24, 8:58 PM

I have code running in my pages under the scriptsscripts folder, is the easiest way to make it such that I can see the logs is to move this under a /functions/functions directory? Is there really no other way to see the server-side logs? i want to avoid generating functions per each file

Nicolas•3/11/24, 9:01 PM

This is what happens when I try to stream logs

Nicolas•3/11/24, 9:03 PM

I don't think so? I don't even know how to check for that lol, there doesn't seem to be an option for that in any of the tabs

Chaika•3/11/24, 9:03 PM

nvm actually, the better question is, what are you trying to do exactly?

Chaika•3/11/24, 9:03 PM

Functions are a Pages thing, yet you're in #workers-discussions and have a wrangler.toml

Chaika•3/11/24, 9:04 PM

those scripts also look like local static website js and it doesn't look like you're using a framework or anything

Nicolas•3/11/24, 9:04 PM

oh yea I should probably switch channels lol

Just trying to log some runtime errors that are happening in my api.js, yea no framework

Chaika•3/11/24, 9:05 PM

so those are just local js running in the browser?

Nicolas•3/11/24, 9:06 PM

oooo i didn't even realize that, I thought this all shipped to the pages backend

Nicolas•3/11/24, 9:06 PM

lol your right

Hello.
Is there a way to change the egress IP of Cloudflare Workers to a fixed IP?
When connecting workers to external services, I need to specify the IP of the workers to the external service from a security standpoint.
However, specifying all of Cloudflare's IP ranges ( https://www.cloudflare.com/ips/ ) is risky, so I would like to specify only the IP of my workers.
Is it possible to do this?

Cloudflare

IP Ranges | Cloudflare

This page is intended to be the definitive source of Cloudflare’s current IP ranges.

kian•3/12/24, 5:02 AM

Nope.

kian•3/12/24, 5:03 AM

You'd need to check the CF-WorkerCF-Worker request header in order to restrict traffic to only your Workers.

Kkian Nope.

sathoro•3/12/24, 8:33 AM

we do it immediately by setting a flag on the user object that we load in on every request anyways. we set the flag on events like the user changing their password. zero overhead (since we load the user information from a DO anyways to check usage, permissions, etc), and invalidates existing sessions immediately even when using JWTs

sathoro•3/12/24, 8:34 AM

this is with Supabase auth. and we don't sync anything, we just cache the JWT result in a DO. its super nice

dolarshop•3/12/24, 5:12 PM

New to workers and I'm trying to deploy a Hono app but I'm getting

import * as Bun from 'bun';
You can mark the path "bun" as external to exclude it from the bundle, which will remove this error.

I added node_compat = true to wrangler.toml and it removed some of the other errors but can't find how to mark this as external.

Unsmart•3/12/24, 5:15 PM

You cannot use the bun runtime on workers. I dont think you can really even import bun like that even if you are using the bun runtime

dolarshop•3/12/24, 5:19 PM

haha yeah i'm using Bun.
