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?

Tom Ellis•2/21/25, 10:35 AM

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?

Benos•2/21/25, 11:29 AM

Does anybody know what would be the average/normal latency for:

API call to the Rate Limit runtime-api
Get the value of Key in KV
Get one indexed row from D1
Grab a value from key in Durable storage

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

i mean chat api from open ai. i understand we have worker AI. But it only for open source model and they are not good when compared to open ai or anthropic.

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

thanhle•2/21/25, 5:17 PM

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.

Question around Rate Limit bindings https://developers.cloudflare.com/workers/runtime-apis/bindings/rate-limit/ is there a way to add more than 1 to the rate limiter?
My use case is as follow:

Worker is called and forward to a backend service via HTTP (hosted outside of cloudflare) based on the "ClientID" (in the headers)
The backend calls another API and may get blocked
I know that the send API has a rate limit of around 150/10sec
I want to return 429 to as many requests as possible to not overwhelm the backend

Simple implementation is just to put the same rate limit
More advanced one is to increase the key more than once if I get a 429 from my backend.
I don see a way to do something like:
const { success } = await env.MY_RATE_LIMITER.limit({ key: pathname }, increment_num=20)
Should I just loop 20 times over env.MY_RATE_LIMITER.limit({ key: pathname }) without an await and return the 429?

Cloudflare Docs

Rate Limiting · Cloudflare Workers docs

Define rate limits and interact with them directly from your Cloudflare Worker

danboyle8637•2/22/25, 6:17 PM

In my app I want to send a request to another Worker using my service binding but I need to construct the request as a new request.

However when I build my new request --

new Request()

new Request()

I get a type error when passing the request to the

env.BINDING.fetch(req)

env.BINDING.fetch(req)

because my request is a native fetch request and not a Cloudflare request.

How can I type my new request so I avoid the type error when passing it to the binding?

Cloudflare smart routing placements seams incorrect?

I have database hosted on ap-south-1 (BOM) and I have my API deployed on cloudflare workers with smart placement enabled. When I send a request from Delhi, India, I expect the request to be routed to either DEL datacenter or BOM (Preferred) datacenter but for some reason it is getting routed to FRA (Germany) and sometimes it is getting routed to SIN (Singapore).

Because of this my I am having huge latency between my database and api which makes our whole app a lot slower.

Any tips on how to fix this ?

Finally solved it, you will have to get cloudflare pro account for a custom domain and set up same custom domain for the worker.

Basically without pro account cloudflare workers are not much useful in India

Looking at gradual deployments, is there a way to specify a minimum version by date?

Seems crazy that there's no such header for this very common use case: deploy workers + app the same time, gradual rollout for older versions, newer versions must use workers past their build date

How to expose the Cloudflare environment form wrangler to the front-end (client) side of a full stack app with Vite?
I need to export the environment name

preview

preview

production

production

(the only environments accepted by wrangler for a pages project), but I don't know how to intercept this at build-time with the Github Integration of a SolidStart app, build with Vite.
Ideally I only need to export a URI for each environment this being the main purpose, the

preview

preview

app needs to make some API request from the client to an endpoint different form the

production

production

, and since Environment Bindings are only exposed from the context object of the workers I can't reference the correct URI for different remote environments

preview

preview

is gonna be my staging while

production

production

is of course the prod.

Ssathoro "useless"

Niveth•2/24/25, 6:11 PM

I think my reaction was bit strong. I wasted one whole day going through community forums to figure out the issue. I really wish cloudflare addressed in their documentation somewhere so we can just buy pro account in advance.

Other than this one particular issue, I had really good experience with all other cloudflare offerings like queues and durable objects.

Brett Willis•2/24/25, 8:01 PM

So stoked about the new Images bindings API! Got some questions though:
In this example, doesn't the

env.IMAGES.info(stream)

env.IMAGES.info(stream)

call consume the

ReadableStream

ReadableStream

and then

env.IMAGES.input(stream)

env.IMAGES.input(stream)

try to reuse the stream that is already consumed? Is there some magic going on there?
Can I call

env.IMAGES.info(stream)

env.IMAGES.info(stream)

on a stream just to verify info and then pipe the same already-consumed (?) stream to R2 without any transformations? Or do I need to tee the stream?
Also how are these transformations priced? Is

.info(stream)

.info(stream)

free? Do I assume that each call to

<some transformations>.output()

<some transformations>.output()

triggers one "unique transformation" quota usage? E.g. 5k free

.output()

.output()

calls per month then $0.5 per 1k thereafter?
