Anyone have experience migrating NextJS applications to Cloudflare? Pricing looks attractive. Where would you migrate to, cloudflare pages or cloudflare workers?

Can someone help me about how to get Secrets Store working locally? workers-and-pages-helpSecret Store In Local Dev Mode?

Puliczek•4/25/25, 7:46 AM

Guys, I have a question. Is it possible to add Vectorize Dimensions and Metric value in the 'deploy to Cloudflare' config? Check out my repo: https://github.com/Puliczek/mcp-memory. There's an extra note on setting up Vectorize, but I would like to do it programmatically. Is it possible?

Ccrossbeau even more odd. I ran a printenv and my secrets are populated, but my env vars ar...

We have the same problem. Did you figure this out?

crossbeau•4/25/25, 11:38 AM

Lol… just set all our values to secrets… so silly that we need to convert all values to secrets to expose to build env, which isnt even documented as to being the case. The docs made it seem as if they would be available

it was available before.. seems that they've changed the secrets behavior secretly

Rostislav•4/25/25, 11:52 AM

I suppose it's related to the new "Secrets Store"

Avi•4/25/25, 10:20 PM

is there any way to force a worker to run in a particular region?

Avi•4/25/25, 10:21 PM

or prevent a worker from running in a particular region?

AAvi or _prevent_ a worker from running in a particular region?

Regional Services gives you the ability to accommodate regional restrictions by choosing which subset of data centers decrypt and service HTTPS traffic.

Avi•4/25/25, 10:36 PM

thanks @Hard@Work - and do you know if there's a way to check (from within a DO) where it was spawned?

Avi•4/25/25, 10:37 PM

i assume req.cfreq.cf would indicate the location of the where the request came from, not where it was served from

Avi•4/25/25, 10:44 PM

interesting- is there any documentation/commitment to support that? or is that just a clever trick?

Sseflanka Is there any ETA on when Cloudflare SQL D1 clusters will be available in Brazil?...

Chaika•4/25/25, 10:45 PM

Cloudflare doesn't really do ETAs, not until something is very close. D1 depends on Durable Objects being in the location. They talked about supporting South America and India supported by the end of 2025 but obviously that never happened, would assume it's still something they're working towards though

seflanka•4/25/25, 10:47 PM

Chaika•4/25/25, 10:48 PM

I don't think it's documented anywhere but can't imagine they'd ever mess with it too much. Fundamentally you're fetching inside of the Durable Object, routing to another location wouldn't make sense. Afaik rn it's all handled on the same machine that the durable object is on. It's been a thing for years now
Fetching /cdn-cgi/trace and parsing it is something cloudflare itself does as well on some of their pages/utilities.

Here's a one-liner:

((await (await fetch("https://www.cloudflare.com/cdn-cgi/trace")).text()).match(/^colo=(.+)/m) as string[])[1]

Hard@Work•4/25/25, 11:05 PM

The req.cfreq.cf value is set in the first Worker in the chain. It isn't modified if you pass the request on to another Worker(via Service Bindings) or a Durable Object

Avi•4/25/25, 11:16 PM

in other words, it woul dindicate the location the request came from, not necessraily the location the DO was served from, right?

Hard@Work•4/25/25, 11:17 PM

Yep(and note too that the location is derived from the IP of the incoming request, which may not necessarily be accurate)

Avi•4/25/25, 11:47 PM

strange, even though cdn-cgi/tracecdn-cgi/trace shows my colo is FRAFRA (France), OpenAI is still rejecting my requests when I connect via a VPN to Hong Kong

Avi•4/25/25, 11:47 PM

its like somehow it... knows

Avi•4/25/25, 11:47 PM

yet the DO is apparently definitely running in a supported region (France is supported, HK is not)

Avi•4/25/25, 11:47 PM

i just can't figure out how this is possible

Hard@Work•4/25/25, 11:51 PM

FRAFRA is Frankfurt in Germany. But also, iirc, requests from Workers still pass along a connecting IP header, and I'm wondering if that also happens for the DO

Avi•4/25/25, 11:51 PM

ahhh

Avi•4/25/25, 11:51 PM

Avi•4/25/25, 11:52 PM

requests from a DO might include, without my explicit configuration, a header indicating the IP the incoming request originated from?

Hard@Work•4/25/25, 11:53 PM

That's what I'm guessing might be happening

Hard@Work•4/25/25, 11:53 PM

Also might be some other kind of detection system, idk

Chaika•4/25/25, 11:55 PM

Looks like openai does use cf for their API as well

HHard@Work That's what I'm guessing *might* be happening

Avi•4/25/25, 11:58 PM

i just set up a server that will print all headers of incoming requests and im gonna test this
