they did but not sure if extremely high / necessarily higher than other days of using the sites quite a bit. Have you seen internal worker (or pages) rate limits applying? (e.g. 3.2k in a 15min span doesn't sound that large for something that will download assets/etc)

Might be worth checking out your WAF events and see if that user ran into blocks that has workerworker as rule name - If so, then they're triggering Cloudflare's anti-abuse system for workers

Workers don't have threads, so you can't run things in parallel. Note that you could do a Promise.all() that calls one or more Durable Objects but it wouldn't be a thread per-say, it would be a whole other instance of a DO.

Hello everyone, I discovered a bug while trying to write tests that uses the cache API.
Here's a minimal worker reproduction that can be pasted in the cloudflare playground :

const baseRequest = new Request("http://example.com", { method: "GET" })

export default {
    async fetch(request, env, context) {
        const url = new URL(request.url)
        if (request.method === "POST") {
            const cacheUrl = new URL(`http://cache.key/custom${url.pathname}`)
            const cacheKey = new Request(cacheUrl, baseRequest.clone())
            context.waitUntil(caches.default.delete(cacheKey))
            return new Response("Busted", { status: 201 })
        }

        const cacheUrl = new URL(`http://cache.key/custom${url.pathname}`)
        const cacheKey = new Request(cacheUrl, baseRequest.clone())
        const cache = caches.default
        const cacheResponse = await cache.match(cacheKey)
        if (cacheResponse?.ok) {
            console.log("Returning from cache.")
            return cacheResponse
        }
        const newResponse = new Response("Something")
        newResponse.headers.append("Cache-Control", "s-maxage=3600") // 1 hour
        context.waitUntil(cache.put(cacheKey, newResponse.clone()))
        console.log("Returning Fresh")
        return newResponse
    }
}

const baseRequest = new Request("http://example.com", { method: "GET" })

export default {
    async fetch(request, env, context) {
        const url = new URL(request.url)
        if (request.method === "POST") {
            const cacheUrl = new URL(`http://cache.key/custom${url.pathname}`)
            const cacheKey = new Request(cacheUrl, baseRequest.clone())
            context.waitUntil(caches.default.delete(cacheKey))
            return new Response("Busted", { status: 201 })
        }

        const cacheUrl = new URL(`http://cache.key/custom${url.pathname}`)
        const cacheKey = new Request(cacheUrl, baseRequest.clone())
        const cache = caches.default
        const cacheResponse = await cache.match(cacheKey)
        if (cacheResponse?.ok) {
            console.log("Returning from cache.")
            return cacheResponse
        }
        const newResponse = new Response("Something")
        newResponse.headers.append("Cache-Control", "s-maxage=3600") // 1 hour
        context.waitUntil(cache.put(cacheKey, newResponse.clone()))
        console.log("Returning Fresh")
        return newResponse
    }
}

Over there it works perfectly, the cache gets correctly deleted.
But locally, when running with wrangler dev, it doesn't work (the cache doesn't get deleted).
It also doesn't work when runnning test with vitest-workers-pool T_T

Does anyone has a workaround ?

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•12/6/24, 4:46 PM

No I moved on to other projects. The key here is that the CNAME effectively authorizes the traffic, you might try fetching with an overridden Host header but I doubt that works

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•12/6/24, 4:47 PM

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ

Ꭱ

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•12/6/24, 4:49 PM

I think it’s either create the records or implement your own tunnel directly in the worker

Hi, is anyone experienced with using encryption in nodejs on Cloudflare?

I'm working with cloudflare and want to use createCipherivcreateCipheriv and createDecipherivcreateDecipheriv from the nodejs cryptocrypto module.

However, Cloudflare doesn't support these yet as shown in their documentation:

I get this error:
Error: [unenv] crypto.createCipheriv is not implemented yet!

What alternatives can I use instead?

Workers supports the Web Crypto APIs. Your equivalents there are crypto.subtle.encrypt()crypto.subtle.encrypt() and crypto.subtle.decrypt()crypto.subtle.decrypt().
However the Web Crypto API does not support all of the algorithms available on NodeJS.
So it depends on which algorithm you're after but take a look at the docs:

Warren•12/7/24, 2:44 AM

I am using Workers in Workflows and I am running up against the 1000 subrequests limit. my question is is there a way to clearly see what are the subrequests made in a Worker?

so for context, my worker is trying to do long running job in batches. the issue is I am using another Durable Object as a rate limiter. the problem with rate limiting is I can’t estimate how frequently the rate limiter will be called in a single worker run.

now that I’ve gotten rid of the rate limiter, it seems to not run into the subrequest issue anymore.

my feedback would be:
- if a Worker in a Workflow has hit the subrequest limit, it seems pointless to retry since any retries would also by definition hit the same limit
- I personally feel that this subrequest limit really dampens the promise of Cloudflare platform being serverless and scales infinitely, esp if it includes calling internal Cloudflare resources like Durable

I haven't used CryptoJS, but it looks deprecated. And I haven't used drizzle ORM to tell you if there's a way to do async.
However have you considered returning a plain string type from the ORM, and then having an async helper function to decrypt it in your application code?

const baseRequest = new Request("http://example.com", { method: "GET" })
