Rate Limiting API open beta feedback

The new Rate Limiting API for workers (https://developers.cloudflare.com/workers/runtime-apis/bindings/rate-limit/) is quite interesting to e.g. API a rate limiting mechanism to a API hosted on Cloudflare Workers. However, I think there is a room for improvement to even offer more opportunities leveraging this API. 1) More Rate Limit result details like remaining and reset window ...

Service Bindings on NextJS

Hey everyone, I'm trying to get a NextJS setup on workers. My NextJS app needs to make a call out to another worker, which is setup as a service binding. I've gone through the steps of using wrangler types to generate types, have the latest versions of everything. But whenever I make a call to getRequestContext() I get an error saying that the Cloudflare Request Context can't be loaded. The other challenge I've got, is that when I set export const runtime = edge I get another error saying ```...

silly question about workers billing

hi. i'm currently screwing around with workers to see if it's viable for a thing i want to make. i'm using the free plan and i very specifically do not want to be charged (but cloudflare has my payment details because i'm using the free tier of r2). my understanding is that the free tier of workers limits you to 10ms CPU time per request and just kills the worker after that. and yet my median CPU time is showing as 617ms, see the attached image. is there a way i can verify if this is right or not, and more importantly, is there a way i can check if cloudflare has suddenly started billing me for workers paid or not...

Emulating R2 locally

Hello! The R2/worker docs state:

By default wrangler dev runs in local development mode. In this mode, all operations performed by your local worker will operate against local storage on your machine.

I have a worker pulling files from R2, so no problems there. Also the wrangler deploy is quick, so generally I have no need of local storage. I am curious however what "operate against local storage on your machine" means. Is the general idea that we will setup env.BUCKET_NAME to point to some local folder to make this work? Does the R2 get (e.g. env.BUCKET_NAME.get()) somehow grok this local filesystem link?...

"Update name in Wrangler configuration file to match deployed Worker" even though name is the same

Hey everyone, I took an existing github project of a cloudflare worker, removed my old deployed workers via the dashboard and then created a new one from that github repo. Reason being that I'm switching from my self-built github actions to the new worker preview feature. So I enabled it and now every time I push, the cloudflare integration opens a pull request to change the name of the worker in the worker configuration. The issue is that the name is exactly the same, and said pull request ends up with no file changes. ...

Startup Time Exceeded Despite CPU Profile Showing <400ms

Hey all, I'm running into a weird issue while deploying a Worker. I’m getting an error saying my Worker exceeds startup limits:

✘ [ERROR] Your Worker failed validation because it exceeded startup limits.
To ensure fast responses, there are constraints on Worker startup, such as how much CPU it can use, or how long it can take. Your Worker has hit one of these startup limits...

DNS missing for custom_domain = true worker

Hello there, I'm successfully deploying a worker with custom_domain = true, but the worker isn't responding on the domain because there are no A or AAAA records in my DNS for that zone... I thought the custom domain deploy would automatically create them, but I guess not. Can you tell me what DNS records I would need to add to get the worker to respond on my zone?
