I want to know if it's possible to have a cache for CF workers such that if I come up against the rate limiter, I can just get my response from the cache even if it's stale just to have something returning.

You could use KV/R2?

Hello, I’m Allie!•6/30/24, 4:09 PM

Though both of these options would incur billable usage in addition to the Worker Invocation

HHello, I’m Allie!You could use KV/R2?

StevenOP•6/30/24, 5:17 PM

sure so I can setup a cron job to hit the r2 to cache worker responses. I'd then be hitting R2 first always to see if the response is cached there and if not/"stale hit" then hit the worker, and just in case the worker comes back with an rate limiting error I can just use what I got from R2.

Hello, I’m Allie!•6/30/24, 5:35 PM

Yeah, though unless you set a Lifecycle rule then there should always be something in R2 once you trigger the Cron for the first time

hey guys, i have a cloudflare worker that does only redirections.
for example mydomain.com/path1 then it searches the KVs value for /path1 and redirects to that URL.
But i noticed that i get less visitors on my domain after that. do you maybe know what the issue could be?

Workers aren't based on node.js, they're based on V8 - the JS Engine Chrome and Node.js uses. There is some node compat they've added back in: https://developers.cloudflare.com/workers/runtime-apis/nodejs/ but fundamentally they're never going to have a file system, and currently no node networking support (although I think they were working on that, at least as of the moment it'd be only tcp outgoing, not tcp incoming, or udp in/out), not possible to have generic web servers like express and such, and workers are under pretty strict limitations of needing to startup within 500ms at most, max 128mb of memory and max size of 10 mb on paid

Aditya Mathur•7/1/24, 6:44 PM

Hello! I am using WorkerKVWorkerKV for some experiment and this is my code

await this.namespace.put(keyWithPrefix, JSON.stringify(payload), {
  expiration: Math.floor(payload.resetTime.getTime() / 1000),
});

await this.namespace.put(keyWithPrefix, JSON.stringify(payload), {
  expiration: Math.floor(payload.resetTime.getTime() / 1000),
});

So here are the problems I am facing -

The key is not getting deleted, I am still getting the old value when I fetch it
If I want to update the value for a key but still want to have the same expiration time, what will be implmentation for that? Should I just pass the expirationexpiration props again?

Is anyone aware of a mechanism for "CNAME flattening" to be done by other domain providers in a way that is compatible with workers?

I.e. if you want to host a worker at myroute.com, you have to define a "CNAME" for myroute.com. That's not wise (all subdomains / records get borked)... so Cloudflare has a mechanism called "CNAME flattening" that reconciles this problem by turning the "CNAME" at the root into A records on demand.

However, Workers require "recognizing" this domain as being CNAME'd to the worker route in question. They recognize Cloudflare "CNAME flattening," but not similar mechanisms by other providers (i.e. Namecheap provides ALIAS records that do much the same).

Is anyone aware of a way to get this to work? i.e. host a domain on Namecheap and CNAME the root to Cloudflare workers in a way that makes Cloudflare workers happy? (They just see an A record).

Chaika•7/2/24, 1:00 AM

it's more that you can't just point cnames to cloudflare zones or workers, it just doesn't work

Chaika•7/2/24, 1:00 AM

workers don't have unique ips or anything, you're just pointing to the edge, a shared ip from a pool

Chaika•7/2/24, 1:01 AM

on your own zones you have worker routes/custom domains which allow that specific hostname to execute

cole•7/2/24, 1:01 AM

Right. So I have that set up, but I'm using the SaaS worker stuff, so the other domains have to CNAME to my route

Chaika•7/2/24, 1:02 AM

Right, CF For SaaS enables that. You can't get apex proxying outside of Enterprise so you need to rely on alias records, but it should just work if you go through the prevalidation and such
