hey i noticed i sometimes get 524 http errors on my worker while requesting another api with the nodejs fetch request, i searched a little and its a "cloudflare timeout error", why does this happen?

and when or is it in sometime possible to use axios instead of fetch?

Rich•5/1/24, 2:31 PM

I've been told it should purge so long as you use

caches.default

caches.default

(rather than

caches.open

caches.open

) -- however we've been unable to get purging to work sadly.

Hi, Does changing a worker's Usage model in cloudflare worker dashboard incur downtime or is it only applied to new instances of that worker?

Cyb3r-Jak3•5/1/24, 9:38 PM

What do you mean? You can use a lot of npm packages with workers

crusaderay•5/1/24, 9:38 PM

Sorry. I mean python

Cyb3r-Jak3•5/1/24, 9:44 PM

I believe so. I know you can't use requirements.txt files yet but can use the built-in packages support. I'm pretty sure they are open to adding a lot more packages but also worth asking in #

Unsmart•5/1/24, 11:46 PM

Bun will be its own thing no point in tripping over what they do

but yeah I don’t really see cloudflare adding that. You can just setup the proxy server you make to accept the options of a request in a post pretty sure that’s at least the normal way of doing proxies

Ashley•5/2/24, 11:10 AM

Random Q: I think the answer is no, but are there egress charges for Workers? I've been reading https://www.cloudflare.com/en-gb/learning/cloud/what-are-data-egress-fees/

https://developers.cloudflare.com/workers/platform/pricing/ and there's no mention about workers. It focusses on R2, but in the pricing, there's nothing about egress - just requests/CPU etc. so while it doesn't explicitly say, is there anywhere that explicitly says in the docs/website (and Pages too as a bonus!)

Hello, I’m Allie!•5/2/24, 11:12 AM

Ashley•5/2/24, 11:13 AM

I thought not, it seems weird Cloudflare doesn't shout about it more, and only talks about R2? Like, even just saying "no egress charges" under Workers pricing would make sense

Unless I am just blind. Is it fair to say there are zero egress charges for any Cloudflare developer products?

Ashley•5/2/24, 12:35 PM

CalBoy•5/2/24, 3:39 PM

Is there anywhere to see recent worker releases etc? My worker has started to do weird things with the cache API (things aren't caching as long as I would have expected) and I've not touched that code in some time.

cache API

Assets in cache are evicted based on access frequency, it's possible they changed some internal cache stuff too and I don't think that would be in the Workers change log at all. As long as they being put in cache and serving HITs (the cache api is actually working), then the rest is up to the cache service

CalBoy•5/2/24, 3:55 PM

Short of pinging a ticket into my AM there isn't anyway for me to know if something has changed in the cache service I imagine?

smohian•5/2/24, 5:40 PM

I have an API that I am calling in my worker, which requires my IP address to be whitelisted to access. How would I get the IPv4 address of my worker once it is deployed so the API can be accessed in the worker?

Isaac McFadyen•5/2/24, 5:51 PM

You cannot. Workers run on every machine in the Cloudflare network and so use many different IP addresses.

AD•5/2/24, 6:17 PM

Hi all,

I’m kinda new to JS backends and serverless in general. I’ve recently followed this tutorial (https://youtu.be/H7Qe96fqg1M?si=dtk0DoiFW275Fc20) and had a mostly pleasant experience.

I’m wondering now how would I build a larger backend to power an API with Cloudflare workers. If I wanted to have multiple workers responding to different paths like controller endpoints, what’s the “recommended” way to achieve that? I’m trying to assess feasibility of using this toolchain more deeply in building products and want to make sure I understand its use cases and how to do basic things before I commit too much time to learning it

Callum•5/2/24, 7:26 PM

Hey all, I am exploring service bindings right now, and the docs state one advantage of service bindings is:

Isolate services from the public Internet. You can deploy a Worker that is not reachable via the public Internet, and can only be reached via an explicit Service binding that another Worker declares.

https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/

However, I can't find any instructions on how to achieve this - my assumption being that this is only true if you use the RPC interface, rather than the HTTP interface. Is that true? and if that is the case, I guess it is less clear to me what the advantage of setting up a service binding for a http interfaced worker. Thanks in advance for the help!

how can you specify which environment the secrets get applied to? (For a pages project), does automatically figure it out like it does when deploying?

Elia•5/2/24, 9:55 PM

Guys, regarding Workers <> Neon
What's more performant,

utilizing the "prebuilt" way of connecting (think it uses websocket to connect to a neon proxy)
utilizing raw TCP connection to it via hyperdrive
?

Elia•5/2/24, 9:56 PM

Since websocket also needs tcp in the beginning I'd imagine the hyperdrive way of doing things to be better
