if i try to add a route, i see i have no zones available

Dawson•4/25/24, 8:20 PM

Hey all, I need to get my API request latency down dramatically globally. I am using:

Workers, TS, Hono, Upstash Redis, and Turso

Dawson•4/25/24, 8:21 PM

I would like to get it from 150-300 -> around 80

Dawson•4/25/24, 8:22 PM

Theres an API that does this, could it be that they just cache every response to cf cache? They deploy to workers and use hono

Unsmart•4/25/24, 8:29 PM

Latency there is going to be highly dependent on where your databases are

Dawson•4/25/24, 8:31 PM

Is turso good for this? Would D1 be better?

Dawson•4/25/24, 8:31 PM

CF-Cache works great, but I need to bill the user for every request. Any way to do this?

jason•4/25/24, 9:01 PM

Is it possible to use got (https://www.npmjs.com/package/got) in a worker? I'm trying but getting a bunch of errors about failed imports and such.

jason•4/25/24, 9:06 PM

My main issue at the moment is sometimes I am doing some subrequests with the built in

fetch

fetch

library and they are failing with 521 status codes. I don't understand why that would be. So I was going to switch to a different http library to see if that would help at all.

Chaika•4/25/24, 10:18 PM

no, looks like that uses node:net/raw sockets

Chaika•4/25/24, 10:18 PM

Workers use V8 Isolates, in a web like environment. Not node,js, although they support some node functions via node compat. They support TCP Sockets through their own interface, but not node networking or raw sockets, nor UDP

Chaika•4/25/24, 10:20 PM

Your options are pretty much:
Use Fetch which sort of goes out through the CDN/normal request path
Use something built on top of custom TCP Sockets API which uses Cloudflare WARP IPs (no list of them). You'd suffer from not being able to keep connections warm/new connection each time and such though

Chaika•4/25/24, 10:21 PM

521 is web server down

Error 521 occurs when the origin web server refuses connections from Cloudflare. Security solutions at your origin may block legitimate connections from certain Cloudflare IP addresses

If it's something you control, does it work through a normal proxied record? Are you specifying a non-standard port?

Hi everyone
I've been having problems using Workers & Pages and D1
With my team we created a D1 database and we want to "connect " it with our web app. We want to connect Backend with Frontend, pulling data from the D1 database and use it on our app (i don't know how to call it)
Could someone help?

so i would need help on how to insert this data into the DB

keithj5389•4/26/24, 3:00 AM

Does anyone know if there is a worker that will allow me to browse my R2 backup folder of JPGs ? And ideally convert them to thumbnails on the fly & save a copy in a /thumbnails folder too. (I don't want to use the $5pm Images product). I'm happy to write one myself, but I am currently time poor.

Can I set cache headers from worker and have the next requests for the same URL skip the worker completely?

Rich•4/26/24, 9:39 AM

I'm finding "Purge Everything" is failing to purge cache entries written using the Cache API and I've got a suspicion it's related to the fact we open our own cache rather than use the default, i.e. caches.open('app')caches.open('app') vs caches.defaultcaches.default.

Can anybody confirm this is expected behaviour and if so, is there a way to purge the 'app' cache instead of the default one?

Hello, I’m Allie!OP•4/26/24, 9:44 AM

You cannot, no. All requests to a Worker route result in an invocation

onnimonni•4/26/24, 10:07 AM

A bit tangential but related: how does one protect against major cloud bill if DDOS happens with workers?

Might be worth updating the docs here https://developers.cloudflare.com/workers/reference/how-the-cache-works/#purge-assets-stored-with-the-cache-api to mention some of that applies to cache.opencache.open

Hello, I’m Allie!OP•4/26/24, 10:49 AM

If it makes a difference, the Cache API doesn't validate that the domains of the URLs you pass in exist. So you could just make up a fake domain to create different cache spaces

Rich•4/26/24, 10:51 AM

ha interesting. It's a really funny API to work with tbh. Kinda dancing around http even though a lot of use cases would be simpler by just passing a string as the cache key.

Rich•4/26/24, 10:52 AM

out of interest, are cache entries written via the Cache API considered part of the zone the worker is running on or is it the zone of the url being cached?

Rich•4/26/24, 10:52 AM

e.g.. worker on foo.com caches something under bar.com

The zone of the Worker. You can cache a cloudflare.comcloudflare.com request, but it won't affect the actual cache for cloudflare.comcloudflare.com

Hello, I’m Allie!OP•4/26/24, 10:53 AM

Would be very bad if you could mess with other people's caches that way...

(we're caching API calls to shopify which I know is also on CF)

Rich•4/26/24, 10:55 AM

but I guess that's actually specific to the ability to single-file purge, i.e. because shopify is on CF then we can't single file purge, as they own that... but maybe we should just change it to be cached under https://{uuid}.comhttps://{uuid}.com or https://domain-we-own.comhttps://domain-we-own.com and then we can single file purge?

Rich•4/26/24, 11:07 AM

Although still worrying to think the owner (shopify) can purge our cache entries "Sorry, you can not purge the asset. Only the owner of notexample.com can purge it"

Hello, I’m Allie!OP•4/26/24, 11:12 AM

No, I meant put it on a non-existent subdomain of your domain

Hello, I’m Allie!OP•4/26/24, 11:12 AM

Since you own it, then only you could break it

It is a real zone, but afaik you can't actually add it as a route, you need to do `workers_dev = tru
