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

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

That is actually pretty cool, that also means that if you need to do a simple POST request you can just use sendBeaconsendBeacon without having to pass the excecution context around, I might use this as my amplitude transporter

Does anyone know if we can force outbound Worker requests having an IPv4 address?
We are using an external service (so not hosted on Cloudflare), that can't handle incoming requests since they are coming from an IPv6 address. They can only handle IPv4. Is there something like "Pseudo IPv4" but for outbound requests?

If the external service doesn't have AAAA records/support IPv6, how would you be connecting to them over IPv6? Workers are cool but not magical lol

Chaika•7/2/24, 10:39 PM

fetch uses the normal cdn pipeline too which prefers IPv4 over IPv6

If I understand correctly, would they need to enable "Pseudo IPv4" on their Cloudflare account then?
