Fhey! in my pages proejct i'd like to add some extra workers. how can i put them into a subdirectory with their own wrangler.toml and deploy?
Fah
-c will do the trick.
II managed to bring this down to
"Service bindings are fast. When you use Service Bindings, there is zero overhead or added latency. By default, both Workers run on the same thread of the same Cloudflare server."
And all the RPC call does is read a environment variable. Curious if anyone has any insight into this?
~91ms by setting the edge config worker to smart placement I guess? But the binding latency is still not 10ms< which I expect since service bindings should run on the same thread / isolate right? In the docs it states:"Service bindings are fast. When you use Service Bindings, there is zero overhead or added latency. By default, both Workers run on the same thread of the same Cloudflare server."

HHow are you testing the speed?
ITime.now before and after the RPC call and log tail that pushes it to a log aggregator (axiom)
HAre you doing any other work before that point?
NI was following the Cloudflare Workers KV quick start guide and ran into an unavoidable error:
✘ [ERROR] Error processing request: TypeError: Cannot read properties of undefined (reading 'put')
I have no idea what this error means, and there aren't any docs or resources available to help.

LHi, I want to make websocket server for a game in worker. What does "Max of 30 seconds of CPU time per invocation" or "10 milliseconds of CPU time per invocation" mean? Does my websocket stops if it go over?
NHey @Mike Nomitch | Workers PM regarding your recent message on the announcement channels about containers in the workers platform, we have a very specific use case that is currently being delegated to fly.io which basically consists of the execution of long running tasks in an asynchronous manner, think of it as a job runner that can run a container instance to completion with parameters passed as environment variables.
We basically use it as a way of executing bulk Tasks like post processing on media, AI tasks, report generation, RPAs, puppeteer and other such things where system dependencies are needed.
Our main reason for delegating it to fly.io right now is that they don't impose a time limit so our long running tasks don't get timeouts while still providing quick startup times once the image is cached.
We find that currently no cloud provider provides a complete solution for running asynchronous jobs while just paying for the compute time and providing fast startups (we achieved that with fly.io but it required us to hack around with their platform API and writing our own scheduler) so I think that would add great value to the Cloudflare developer platform.

DDoes anyone know what is the key for package.json conditional exports for wrangler esbuild?
worker, workers or workerd
KIt'll also try
worker then browser if there is no workerd key.IEssentially what I do is this in my pages workers / functions (next-on-pages) (simplified)
EHello guys I need help with cloudflare worker
as I was using K6 Gafana to load-test my worker.
It was went well at the start but then at certain time I cant sent request anymore. I'm not sure wether its the problem from K6 or Cloudflare worker that block repetitive coming request with in short period of time.
if the problem is with my Cloudflare worker, how can I unlock this block feature to test how much can my Cloudflare worker can handle? do I have to upgrade the plan or Are there any better solution to solve this
thank you
ps. I attatched the report file from my K6 to see whats the actual problem.

KI need help
EHi, i want to save headers and other stuff from each visitor through workers, what would you recommend for it? I made a worker for saving in D1 but i noticed the data cant be downloaded and i would like to download that data locally. I appreciate your help
CI personally use AE but you can't download from that. You can export the data from D1: https://developers.cloudflare.com/workers/wrangler/commands/#export
Ewould maybe hyperdrive be an option?
UWhat exactly is your goal? Why are you downloading data locally?
Ei would like to download it and collect it and then do some study about my traffic
Ethorugh months
Ethrough*
UWhy not just feed it to an analytics tool and use queries in that instead of downloading it? AE is good if you only need 3 months
Esorry but im new to this and dont understand completely what you mean by AE
U#analytics-engine
Eand is it possible to read that data externally or so? because i would like to create my own overview with all that information.
UYes there is an API you can post queries to
Edo i need a page on my domain for that? because i use my domain mainly for redirecting
Gstill here from the discord block incident
HNo, though there is a max number of outgoing connections(6)
SSince this is backed by WAF does using it to limit an endpoint stop the requests from counting towards the daily limit?

Sis there a way to decrease number of requests for workers , as each visit to my website is hitting the worker hundreds of time , for each path , and for each request it count 1 request
SI just want 1 worker request for each ip address nothing more , can i do that
KI’m traveling so I’m a bit late in seeing this, but switch router.handle —> router.fetch should fix your issue. “handle” was finally deprecated fully in v5 
When you access router.handle now, it’s trying to register a route on the HANDLE verb instead of processing a request… so it fails to respond.

KFor more help I def recommend jumping on the itty discord - folks there will beat me to answers all the time! 
HYou would need to reduce the requests your Website makes. This can be aided with stuff like SSR, though you would probably still have 2/3 requests per page view
MIs it possible to add specific query string parameters to be redacted from Cloudflare's request logs for GET requests?
ADid you find a way to make this work for (larger) files in the cf ecosystem?
ADid you find a desirable alternative using cf building blocks?
