Vitest and cache

Hello, I'm trying to test the cache process of a worker (proxy requests). It's a very simple setup, it receives a request, if there's a cached response, return it, otherwise fetch a different origin, cache that response and return it. The worker works as expected, but in the tests the cache.match never matches, always returns undefined. Am I doing something wrong? Or is this not supported? Example code in attachment....

Clarification needed on confusing documentation on R2 Bindings for pre-signed URLS

I'm trying to follow this documentation which seems to infer that I can generate a presigned url from a binding by passing no values for bucket id or key id to the url request. However, the resulting url is missing these in the url as well. Is this documentation actually correct? https://developers.cloudflare.com/r2/api/s3/presigned-urls/#presigned-url-alternative-with-workers...

Worker + hono without typescript

I see that most examples has a hono<..> for bindings, as I'm only using js, is worker support mixing of both? Do I need to specify typesctipt as language when setting up a new worker using wrangler? Sorry I'm new and moving from deno deploy

Added vars through wrangler.toml was not added to dashboard secrets

This is a pages project. I added a var to [vars] in my wrangler.toml and when I merged my PR it was not automatically added to my secrets in the dashboard settings. Yesterday I merged a PR with vars added to wrangler.toml and they were automatically added to secrets. Should note that the new var which was not added is a number, which worked fine in development. I will try making it a string in wrangler.toml but this is odd behavior, if someone could explain.

ci on workers project

Hi folks. I'm creating a Remix app using Cloudflare Workers as a learning exercise. The template I'm using: https://github.com/vhscom/remix-cloudflare-template I'm able to run wrangler deploy on this project to run the custom build and deploy the running app to a workers.dev domain. Though when I try and hook this app up to build from the GitHub repo via the Workers & Pages section in the Cloudflare Dashboard it builds and deploys to a pages.dev domain and not a workers.dev domain yet the Preview URLs never resolve. Could that be because Workers projects (those with main = "index.js") are not yet supported by Cloudflare Pages?...

Use wildcard domain with worker (assets)

I'm trying to make subdomains work with a wildcard. Because worker domains do not support wildcards, I'm just doing it with a DNS entry. This did not work with assets (CORS error) so I added a route rule that adds access-control-allow-origin: * to the response headers. Now, when I go to the subdomain, the assets are loaded but any other request to the domain still return http 522 responses. The domain without the wildcard works just fine....

Redirect Worker only works on localhost

Hey, I decided to do a chrismas day hobby project. I wanted to set up a simple domain redirect service to try and replace my paid redirect SaaS. Never done it before, but ChatGPT said it wasn't too hard. I have the whole thing (Wrangler, VSCode, Git integration) working and it performs perfectly on localhost. I can't seem to get it to work for the source domain/route that I want. I was getting 1000 errors for a while, then I started getting DNS_PROBE_FINISHED_NXDOMAIN errors. I don't know if my problem now is propegation related (I've been tinkering around with DNS files for a few hours) or if I just am not on the right track at all....

Fetch requests to third party api

I'm new to workers. I have a very simple script that reaches out to the API for ipqualityscore.com. They API is authenticated with an API key in the url. This works as expected with the wrangler dev server, but in production I get an error back from the API that the API key is invalid. I have quadruple checked this, and if I log the url that fetch is reaching out to and just paste it in my browser it also works as expected. Seems like there is something happening to the request specifically when...

OpenTelemetry + Hono

Hi there, has anyone an example on how to integrate OpenTelemetry with Hono? I found this PR on hono: https://github.com/honojs/middleware/pull/901 But it looks like the node-SDK package isn't supportewd on Cloudflare Worker. Gives startup, compile issues. Also found this: https://github.com/evanderkoogh/otel-cf-workers But I have zero clue on how to add it to hono. The setup I tried doesn't log anything 😦...

I have Caddy to proxy to wrangler for a worker. In my local I am struggling to get the sub domain. I know I can pass host wile launching wrangler but that wont scale for integration tests. And when I add this in Caddy hoping it could be a decent workaround, I am shocked to see the following behavior: request_header X-Original-Host customer3.mydomain.app...

Is it possible to use service bindings with `vectorize` db?

I have a worker A that uses worker B. This worker B has bindings to a vectorize index (this index works when used by itself). Both are deployed (given that vectorize doesn't work locally) , but this fail with Cannot read properties of undefined (reading 'VECTORIZE'), which is the binding defined in the wrangler.toml for WorkerB. I guess i'm missing something obvious or this cannot work. (the deployed url from the worker A fails with Error 1101) ```ts //workerB.ts...
