System Prompt for Cloudflare Workers

I build a system prompt (to be used inside cursorrules or any other ai tool) to generate cloudflare worker code: https://github.com/advany/cloudflare-system-prompt I would love to get PR's to improve this so it makes it easier to generate cloudflare worker code!...

How to access environment variables in Cloudflare Workers when using RPC binding

I'm working with two separate Cloudflare Workers, where Worker A calls a function in Worker B via a binding (RPC). Worker B requires an environment variable to send an email, and this variable should be scoped to Worker B itself, so it doesn't depend on Worker A's environment. Here's the relevant code for Worker B: ```typescript export class WorkerEmail extends WorkerEntrypoint {...

Does it worker get its own wrangler file

Hello. Does each worker gets its own wrangler file or its one wrangler file per project? I'm asking for a few reasons but one, is that when I created a worker using the UI, I was not provided with a wrangler file but when I tried to create one, it told me this project already has a wrangler file. Try it out yourself. Create a basic worker, go to edit code and try to create a wrangler.toml file. It'll give you an error saying that it already exists....

Slow Response Time

npm install timeouts with Workers builds?

I'm noticing build timeouts with my Turborepo npm monorepo which contains about 6 cloudflare workers (and a page) as well as a handful of packages (see screenshots) i'm assuming the issue is because of the large amount of npm dependencies we have across all projects, but i'm not sure what to do about it using install-strategy=nested in my .npmrc, not sure thats relevant...

Workers concurrency

Maybe a dumb question but I tried to learn about concurrent requests to workers - when documentation says only one instance of the worker in a edge server, how will it handle let's say we get 100 requests concurrently to the same edge server? How are memory limits handled? Will it span more workers in the same edge location or it will reject the requests if the instance is already beyond 128mb. Are cancelled requests retried? I am a bit lost trying to understand this topic even after a lot of research into Cloudflare forums also. How do we plan for concurency? GCP Cloud Run offers it as a configurable parameter for each instance of the container....

Using WAF to block Traffic

Hello, We use workers to host our site. Over the past few weeks we noticed some major attacks on our API. We thought it was on the API direct, but turns out after watching the Stream Logs, that we have some people able to bypass Cloudflare protections on the website using crawling tools. We use a subdomain company.workers.dev. However, I this links to our CNAME for our company.com website. I am inside our company.com website WAF settings and attempting to block a few subset of IPs from our workers.dev account page.
How or why is the block not occuring? What light switch am I missing?...

rate limiting issues

Hi Im using the cloudflare rate limiting beta, and it works fine when I make my requests through the browser. When I make requests through my local API client (bruno) it seems to have no effect and will never rate limit the user even if they exceed the threshold. Don't really understand why....

Queue consumer from nextjs worker

I'm trying to figure out what the project structure would look like if you're using the nextjs framework and you're deploying to workers. Supposedly, worker nextjs should support effectively all services (creating durable objects, workflows, service bindings). But where would all of those worker specific files be located? They wouldn't be in the app/api/[route] for nextjs backend routes. Do people just make a seperate folder at the root for all "worker functions"? Any examples people can point to?...
