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)?

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
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I found this very nice guide showing how to fix this issue, however, the worker code seems to be outdated, I had to modify some parts to make it work.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.

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.)
