well I imagine some of it is just simple limitations

Tiered Caching Smart requires an IP/geolocation to use, cache api doesn't give it one.
I know Cache Reserve is also part of "Pingora" which their connecting to origin software, so a step outside of the normal stack/where workers run
plus Cache API is completely free

RichOP•4/30/24, 4:29 PM

hmm I see. I guess the Cache API could accept an IP as a header -- but yeah I suppose the fundamental difference between fetch and the Cache API is the Request passed to the latter doesn't necessarily point to an actual origin -- could be

new Request("https://this.doesnt.exist.at/all")

new Request("https://this.doesnt.exist.at/all")

.

Given our cache key isn't really a

Request

Request

, I wonder if we're better off ditching the Cache API and implementing a more standard key / value cache with R2 or KV

bene2591•4/30/24, 7:13 PM

hi, if I store assets into cache using the cache api using a worker and purge the zone cache where this worker has a route, will these files also be purged?

Adi•5/1/24, 1:29 AM

I got seen zoned on general discussions with this question, figured I'd ask here

. Would love some clarification.

Quick question about the smart placement limitation on RPC service bindings. Is that temporary? Or is it a limitation that is expected to be around for a while? Not looking for a timeline, just some confirmation the vision for RPC.

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

(rather than

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

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

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 #

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

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!)

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?

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!
