Avoid hardcoded IDs in the repository

Hi everyone, I'm testing the worker and I have a question: Is there a way to avoid hardcoding the ID of a D1 in the wrangler.jsonc file to prevent it from being available in a repository, like GitHub?...

Private NPM registry install does not work on Worker Builds

I'm not quite sure what the issue is but there appears to be one. I setup my workers build exactly the same as my pages build with an NPM_TOKEN set in the build env. However sometimes the build fails with ...

Streaming response disconnect hook

I'm experimenting with a worker that responds with an indefinite ReadableStream - for the sake of this example, let's just say that it sends the current time as a string every second. I'd like to know when the client manually disconnects, and when that happens, write the number of messages I've sent until that point to a data store. Is there any way to achieve this reliably with Workers? I'm primarily interested in Rust, but would also be interested in a TS/JS solution.

Local Integration Testing

I need to test my stripe webhook and also test against my d1 database after the webhook is ran which is not possible via vitest. I cannot use vitest-pool-workers because the endpoint will not be available to my local machine, only the internal testing environment. This is not possible stripe listen --forward-to localhost:PORT/endpoint The first option listed here looks like my best choice:...

How to prevent Worker from running on certain colocations?

We're using Anthropic's API. Some of our users from South Korea are being routed to the Hong Kong Cloudflare colocation, and Anthropic's API doesn't accept requests from China (& Hong Kong). We want to block Workers from routing to Hong Kong (& instead route to, say, the one in Seoul, KR).

Parsing .EML using workers

i have tried using a variety of mail parsers with workers but since workers does not have full nodejs compatibility, i am unable to use buffer or stream etc which is used by popular libs such as mailparser. is there a workaround or a compatible lib which could do it on workers?

My wrangler.toml, which I also have to re-enable in the folder settings after every deployment: ```name = "myworkername" main = "worker.js" compatibility_date = "2023-08-23" ...

Getting blocked when trying to deploy worker

I came across an interesting issue just now. I tried to deploy my worker with some new code so i clicked on the Deploy button. Then the message "API Request Failed: PUT /api/v4/accounts/ACCOUNT ID/workers/services/forwardreleases/environments/production?include_subdomain_availability=true (403)" came up. So i checked in the Network tab of my Browser to see what's going on and it seems like i am getting blocked by cloudflare? At least i see it when i visualize the html it returns i get this what's shown in the screenshot. Ray ID is:

Periodically re-importing D1 database and Maintenance mode

I have a read-only REST API serving (semi) static data. Each month the data changes and we basically get a full name database; there is no diff or whatsoever available. So my idea was to drop the existing D1 tables, and run the import script. And in the meantime return a maintenance response....

My worker serves sitemap.xml but Google can't read it

I don't have a static site on the domain so if cloudflare chooses to not proxy and run the worker then it will fail, but is there a policy about when cloudflare will step back and try to make the client use the static site? I can't be sure that's the problem, so maybe it's something else. Is there a way to see what Google sees?...

Does Cloudflare Workers will handle custom HTTP/S headers?

Hi, I am looking forward to use CW as middleware to create custom headers for a website to secure it in a better way. Website itself has been created using Webflow and there is not a way to add custom HTTP/S headers by the admin panel nor domain registar does not provide any tools to do that. I've learned that CW can do that, so I would like to know how to preprare before I start. Is there an specific knowledge (i know HTML/CSS/JS/TS and tools around like Git quite well). I haven't done that before and I am looking for professional tips to do it properly....
