QUESTION
I'm using KV namespace defined in cargo.toml by adding to it the lines
ANSWER
Answered 2022-Apr-09 at 06:29Wrangler will look for a wrangler.toml unless told otherwise. cargo.toml means nothing in this context, given it isn't a rust project.
once you've renamed your config file to wrangler.toml (or modified your build script to point to cargo.toml in despite of the least astonishement principle) you'll need to declare your globals in an ambient module src/bindings.d.ts

I am trying to use the jwt_simple library in a cloudflare workers webassembly runtime. Following the basic example in the linked documentation, everything works fine up until key.authenticate(claims)? is executed, at which point the following stack trace is generated in my terminal running wrangler:

QUESTION
What version of JS/ES do CloudFlare workers use?
I want to be able to use modern JS like string.replaceAll() but haven't been able to find versioning info in the official docs
ANSWER
Answered 2021-Apr-12 at 15:57Cloudflare Workers always uses at least the version of V8 that is current in Google Chrome's stable channel. (Actually, it usually tracks Chrome's beta channel, but that's not guaranteed.)
This is documented here (as @Calculuswhiz noted in their comment).
QUESTION
I need to configure that requests that match the domain1.com/test// pattern be serviced by the domain2.com application. Tried to configure it as follows. Created a worker, added code
'''
...ANSWER
Answered 2020-Nov-11 at 12:05You have 2 options to add redirects in Cloudflare: Page Rules and Workers.
In both cases source domain's DNS records must be proxied (orange cloud ON).
WorkersOpen the source domain page in Cloudflare dashboard.
Go to the
Workerstab.Manage Workers->Create a WorkerAdd the following code. On matching paths it will redirect a visitor to the target URL. If there's no match request will be sent to the origin (source-domain.com).
QUESTION
There's a very common problem I have seen from many people who use different versions of their site for mobile and desktop, many themes have this feature. The issue is Cloudflare caches the same page regardless of the user device causing mixes and inconsistencies between desktop and mobile versions.
The most common solution is to separate the mobile version into another URL, but in my case, I want to use the same URL and make Cloudflare cache work for both desktop and mobile properly.
I found this very nice guide showing how to fix this issue, however, the worker code seems to be outdated, I had to modify some parts to make it work.
I created a new subdomain for my workers and then assigned the route to my site so it starts running.
The worker is caching everything, however, it does not have the desired feature of having different cached versions according to the device.
...ANSWER
Answered 2020-Aug-05 at 17:23The problem here is that fetch() itself already does normal caching, independent of your use of the Cache API around it. So fetch() might still return a cached response that is for the wrong UA.
If you could make your back-end ignore the query parameter, then you could include the query in the request passed to fetch(), so that it correctly caches the two results differently. (Enterprise customers can use custom cache keys as a way to accomplish this without changing the URL.)
If you do that, then you can also remove the cache.match() and cache.put() calls since fetch() itself will handle caching.
QUESTION
I'm attempting to test the implementation of Fast Google Fonts with Cloudflare Workers, from Cloudflare's blog for inlining the Google Fonts stylesheet directly into the HTML. The implementation itself seems to be working fine when running via the Cloudflare worker. But I wrote some tests, and when running the tests, I get this error that says TransformStream is not defined.
Error when running my Jest test via npm run test:
ANSWER
Answered 2020-May-07 at 23:59TransformStream is part of the Streams API, a browser-side standard. It is not implemented by Node (because they had their own streams long before this spec existed), so you will need a polyfill when testing your code in Node.
Incidentally, the example you're following is fairly old. These days, it would be better to use HTMLRewriter to implement this kind of transformation -- it is much more efficient for rewriting HTML specifically. (However, it is a Cloudflare-specific feature, so you wouldn't be able to test it under Node at all.)
QUESTION
I'm trying to follow this article on cloudflare regarding how to fetch Amazon S3 assets through a subdomain.
It works as expected when I manually define a specific subdomain with DNS like the following:
CNAME ----- assets ------ fullpage.sites.s3-website-us-west-1.amazonaws.com --- orange cloud icon
Then I can access my amazon files when using: https://assets.example.com
However, I want to use a wild card so each subdomain can be redirected to a folder inside my Amazon S3 bucket. I don't want to manually define those subdomains as that's something my web users will generate in their web app.
So, I add the following record with the wildcard NAME. CNAME ----- * ------ fullpage.sites.s3-website-us-west-1.amazonaws.com --- grey cloud icon
Notice I wasn't allowed to use the "orange cloud icon" (Proxied) and I had to use the grey one (DNS only)
Now this URL stopped working as expected: https://assets.example.com
And I get an aws error:
404 Not Found
- Code: NoSuchBucket
- Message: The specified bucket does not exist
What's going on?
How can I solve this?
...ANSWER
Answered 2020-Mar-12 at 17:37Notice how the non-wildcard CNAME record has an orange cloud icon on the right and says "Proxied". This means that requests to this hostname are processed by Cloudflare first, including e.g. running Cloudflare Workers to rewrite the URL.
Your wildcard hostname, though, says "DNS only". This means that the hostname is set up to point directly to AWS's IP address; requests do not go to Cloudflare first. AWS does not expect to receive requests for your hostname, so it returns a 404 error when it sees them.
Unfortunately, Cloudflare only supports proxying of wildcard hostnames for enterprise accounts, so there's not much you can do about this unless you want to upgrade to an enterprise contract, which typically starts at around a few thousand dollars a month.
