Just a quite note for anyone using NextJS and Workers with Stripe and having issues.

Setting the HTTP client helped me.

Using a Static Asset Worker + the Asset binding, the docs say we should expect the same caching behavior - is this still true with run_worker_first enabled? I understand it will still hit the Worker, but then if the Worker calls the Asset binding with the request it receives, shouldn’t that return from cache if it has it? The reason I ask is we’re seeing a 0% cache hit rate with this, but maybe I’m missing something.

Walshy•2/19/25, 12:35 PM

Yes, if the asset service is invoked we always run through cache

Walshy•2/19/25, 12:36 PM

It won't impact zone caching percent though. It's confusing but that will say 0% but you may have like a 99.99% cache hit rate.

I need to see if we can do anything about that

WWalshy It won't impact zone caching percent though. It's confusing but that will say 0%...

Ashley•2/19/25, 1:19 PM

Yeah it just looks odd on the subrequests metrics as it looks like it’s never hitting cache, but I figured it was purely because the response time was ~20ms plus the issue I had last week not handling 304’s, but the dash made me confused

If i create a KV and associate to my worker which i have created for websockets. Will it behave the same as durable object kv?

Ccrossbeau If i create a KV and associate to my worker which i have created for websockets....

Ashley•2/19/25, 10:17 PM

Nope, the key-value store built into a Durable Object will be separate to a KV Namespace - but you can access bindings from the DO if you want the storage shared between a Worker & a DO in KV

Yongkie•2/20/25, 2:09 PM

Hi all, I'm trying the possibility to deploy a full stack Astro application with Pages+Functions+Supabase Auth. I created a folder

<rootproject>/functions/auth/

<rootproject>/functions/auth/

containing signin.ts, signup.ts. In the documentation for local development, I can run

npx wrangler pages dev <DIRECTORY-OF-ASSETS>

npx wrangler pages dev <DIRECTORY-OF-ASSETS>

. Can someone explain what is this directory of assets? Is it the dist folder created after running the command astro build? I tried

npx wrangler pages dev dist

npx wrangler pages dev dist

. The web app can be opened in the local browser, but trying the signup button returns

POST http://localhost:8788/auth/signup 405 (Method Not Allowed)

Hi , please guide me running containers in cloudfare

Containers aren't generally available yet. Hopefully we'll see them in the near future, and there's a sign up form in a recent blog at https://blog.cloudflare.com/container-platform-preview/

dan•2/20/25, 5:00 PM

is it possible to use readablestreams over RPC in service workers? I'm guessing not considering this warning on the docs:

The Streams API is only available inside of the Request context, inside the fetch event listener callback.

The Streams API is only available inside of the Request context, inside the fetch event listener callback.

dan•2/20/25, 5:07 PM

or just generally how do i go about forwarding a stream from a service worker through another worker to the client?

dan•2/20/25, 5:14 PM

the example is:

client calls API (on a worker), hitting an endpoint named
```
/importRecipe
```
```
/importRecipe
```
API worker passes the work off to a service worker
```
recipe-importer
```
```
recipe-importer
```
which kicks off a series of requests culminating in a LLM call that returns a stream (in this case an
```
AsyncIterableStream
```
```
AsyncIterableStream
```
, but I can convert that to a
```
ReadableStream
```
```
ReadableStream
```
. I want to essentially relay this stream back to the API worker, which will relay it back to the client

1984 Ford Laser•2/20/25, 10:06 PM

What do you mean by manually? You will need to define a class in a Worker, bind it and deploy. The REST API only lets you list namespaces and objects within namespaces, not create

Handling Abusive Content on Website

Hi everyone,

I want to create a website similar to Imgur that allows users to upload content.

What happens if users upload abusive content? Will Cloudflare request its removal, or will they immediately ban my account?

hi all - is there any way to set an environment variable or tell whether the current build was triggered by a commit or a deploy hook?

You need to be moderating this content where possible. Many jurisdictions (Australia for one example) will find a platform liable for hosting illegal content, best to be on the safe side

You don't need workerAI for openAI you just send requests to the openAI api. As to whether or not open source models are as good or not is open for debate. The best model will depend mostly on your use case.

you can't use workers AI with openai (doesn't make sense), you can use the ai gateway in front of it tho

the worker works with vercel ai sdk and openai api. the issue here is I am using the vercel ai sdk and after a few message with model, i get the error from worker tell that "cpu time exceeding". I am in the free plan. so there is 10ms limit. the issue here is before return the response to client, the vercel ai sdk doing some transform for that response, these transformation need cpu time to transform the response message from openai.

You could always use the OpenAI API directly, it's a standard HTTP API and they have reference documentation published that you can use

Isaac McFadyen•2/22/25, 2:16 AM

Yes but it will be transformed at build time, and you must use a specific version of Wrangler: https://developers.cloudflare.com/workers/runtime-apis/rpc/lifecycle/#how-to-use-the-using-declaration-in-your-worker

Isaac McFadyen•2/22/25, 2:17 AM

This version of Wrangler will transpile using into direct calls to Symbol.dispose(), before running your code or deploying it to Cloudflare.

Walshy•2/22/25, 1:10 PM

Improvements on the way but yeah that is very heavy sampling
