CORS is not liking this page

ChaikaOP•5/8/24, 8:13 PM

oh is it broken by apple or the latest chrome stuff? rip

az•5/8/24, 8:14 PM

is this not just standard CORS ?

az•5/8/24, 8:14 PM

i will try a different ISP

Aaz is this not just standard CORS ?

ChaikaOP•5/8/24, 8:15 PM

oh a few of them are broken looks like, it should still display most of them

ChaikaOP•5/8/24, 8:15 PM

possible your ISP just had a fluke for a second with routing. If you're checking off the Cf-Ray that should be your input colo, but just to double check, you don't have smart placement on that worker right?

az•5/8/24, 8:16 PM

works fine on icloud private relay

az•5/8/24, 8:16 PM

must just be my ISP

I'm trying to create a worker to use as a service binding following the instruction in the recent blog post javascript native RPCjavascript native RPC but the worker fails immediately with the warning:

The entrypoint src/worker.js has exports like an ES Module, but hasn't defined a default export like a module worker normally would.

The entrypoint src/worker.js has exports like an ES Module, but hasn't defined a default export like a module worker normally would.

This is promptly followed by the error:

How to fix?

The Cloudflare Blog

We've added JavaScript-native RPC to Cloudflare Workers

Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system for use in Worker-to-Worker and Worker-to-Durable Object communication, with absolutely minimal boilerplate. We've designed an RPC system so expressive that calling a remote service can feel like using a library.

No but I can post code, it's only a few lines a this point.

Actually I think I just figured out the problem. If I include

it appears to work.

blindChicken•5/8/24, 8:58 PM

Hello, I’m Allie!•5/8/24, 9:01 PM

Oh... Yeah, that's because

wrangler

detects the type of the Worker based on whether or not you

Does your

HHello, I’m Allie!Does your `class` have a `fetch()` method?

blindChicken•5/8/24, 9:09 PM

No. But neither does the code in examples of the blog.

Hello, I’m Allie!•5/8/24, 9:09 PM

Does your

include a route/workers.dev?

Hello, I’m Allie!•5/8/24, 9:10 PM

The example on the blog appears to be for a Worker that can only be called via Service Bindings, so it shouldn't have any routes/crons/queues, etc.

blindChicken•5/8/24, 9:10 PM

name = "worker-t"
main = "src/worker.js"
compatibility_date = "2024-05-07"
node_compat = true

name = "worker-t"
main = "src/worker.js"
compatibility_date = "2024-05-07"
node_compat = true

Hello, I’m Allie!•5/8/24, 9:11 PM

Try adding

workers_dev = false

workers_dev = false

Hello, I’m Allie!•5/8/24, 9:12 PM

IIRC it adds

workers_dev

workers_dev

by default, unless you add a route

blindChicken•5/8/24, 9:12 PM

Same error!

BblindChicken Same error!

Hello, I’m Allie!•5/8/24, 9:20 PM

Ok, looking at it, it does appear to work if you add a

fetch()

fetch()

method, even if it doesn't actually do anything

blindChicken•5/8/24, 9:22 PM

Yup! added

async fetch(){}

to class and it deployed.

Where could I find well-written cloudflare workers that I can use as reference? Something more complex than the examples in the docs

@HardlyWorkin' It appears to have worked. The binding found worker and called the method. I made a mistake in my code, but that will be quickly fixed.

Steven•5/8/24, 9:56 PM

Hi all, I have a quick questions, I currently have a Worker that is responsible for putting json's in KV that will be read from a Cloudflare pages project. The idea is to prepopulate the cache in order to get super fast pages. At the moment I created a worker that runs fine locally and can add a few thousand entries into my local wrangler state. However after deploying the worker I hit the limit of 50 subrequests. I think I can rewrite the worker to use a queue and split up the work, thus reducing the number of subrequests. But I'm wondering what the best approach is for my use case?
