should I be able to connect to a postgres database on a remote server from a worker using a zero trust tunnel?

did you find a solution?

Ꭱ

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•12/6/24, 4:46 PM

No I moved on to other projects. The key here is that the CNAME effectively authorizes the traffic, you might try fetching with an overridden Host header but I doubt that works

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•12/6/24, 4:47 PM

And per your use case don’t think that even fits right

Ꭱ

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•12/6/24, 4:49 PM

I think it’s either create the records or implement your own tunnel directly in the worker

Hi, is anyone experienced with using encryption in nodejs on Cloudflare?

I'm working with cloudflare and want to use

createCipheriv

and

from the nodejs

module.

However, Cloudflare doesn't support these yet as shown in their documentation:
https://developers.cloudflare.com/workers/runtime-apis/nodejs/crypto/

I get this error:
Error: [unenv] crypto.createCipheriv is not implemented yet!

What alternatives can I use instead?

Thanks in advance!

Workers supports the Web Crypto APIs. Your equivalents there are

crypto.subtle.encrypt()

crypto.subtle.encrypt()

and

crypto.subtle.decrypt()

crypto.subtle.decrypt()

.
However the Web Crypto API does not support all of the algorithms available on NodeJS.
So it depends on which algorithm you're after but take a look at the docs:

Warren•12/7/24, 2:44 AM

I am using Workers in Workflows and I am running up against the 1000 subrequests limit. my question is is there a way to clearly see what are the subrequests made in a Worker?

so for context, my worker is trying to do long running job in batches. the issue is I am using another Durable Object as a rate limiter. the problem with rate limiting is I can’t estimate how frequently the rate limiter will be called in a single worker run.

now that I’ve gotten rid of the rate limiter, it seems to not run into the subrequest issue anymore.

my feedback would be:
- if a Worker in a Workflow has hit the subrequest limit, it seems pointless to retry since any retries would also by definition hit the same limit
- I personally feel that this subrequest limit really dampens the promise of Cloudflare platform being serverless and scales infinitely, esp if it includes calling internal Cloudflare resources like Durable

Brett Willis•12/7/24, 5:44 PM

I haven't used CryptoJS, but it looks deprecated. And I haven't used drizzle ORM to tell you if there's a way to do async.
However have you considered returning a plain string type from the ORM, and then having an async helper function to decrypt it in your application code?

Mitya•12/7/24, 10:15 PM

Hi everyone - for some reason, when I set up a hello world Worker, then run it locally via

npm run dev

npm run dev

, I just get a spinning browser tab with no content. Nor do I see any requests come in to my worker in the terminal (other workers show the URI + HTTP code when requests come in.) Repro:
-

npm create cloudflare@latest -- test-worker

npm create cloudflare@latest -- test-worker

- choose the hello world options; lang = JavaScript; deploy/version control = no
-

cd test-worker

cd test-worker

npm run dev

npm run dev

- Wrangler says "Ready on http://127.0.0.1:8787"
- Visit that URL; expecting "Hello world!"; getting the above problem.
Is there a server status issue with CF?

D Trombett•12/7/24, 10:18 PM

npm run dev

npm run dev

runs locally so any problem with CF should be unrelated

Mitya•12/7/24, 10:18 PM

Yeah that's what I thought

Mitya•12/7/24, 10:25 PM

Sorry, false alarm - for some reason my machine failed to release the port when I stopped the worker before, so I had multiple processes claiming port 8787. Killing these solves the problem

Xulo•12/8/24, 10:27 AM

Yea you are right, CryptoJS is deprecated.

I'm not sure what you mean. Do you mean manually encrypting data before inserting it into the database and then decrypting it when retrieving it? That’s possible but it’s not very practical and can be quite error-prone. But if there is no other way, that's what I can do in the meantime

Here’s what I had before:

This used encryption with

createCipheriv

and works poerfectly, but unfortunately that’s not supported in Cloudflare

Isaac McFadyen•12/9/24, 3:20 AM

No Kinda? Environment variable changes require a re-deploy of the Worker.

Isaac McFadyen•12/9/24, 3:21 AM

You could technically redeploy the Worker via the Cloudflare API from within the Worker itself, if you really wanted to, but generally other (easier) methods are recommended first, like storing the value in KV.

Ashley•12/9/24, 8:12 AM

Does it need to happen synchronously, before the HTTP response ends? If not, you could use Workflows and do batches of 100 and then a sleep. Alternatively, you could use Queues and publish a message per item and have some rate limiting, but Workflows will be better imo. Only drawback will be you’d need to create sub Workflows at a certain point with the current step limit (e.g. you’d have an effective cap of 51,200 inserts per Workflow)

Bradley•12/9/24, 4:39 PM

Hello, I'm trying to use Browser Rendering to replace a puppeteer ec2 instance, and one difference I've noticed is that in Cloudflare the scrollbars are getting captured when taking a screenshot. I don't see any options or differences from the ec2 side that is different, except for manually setting headless: trueheadless: true in the browser creation in ec2. But from what it looks like Cloudflare should be defaulting headless. Has anyone seen this issue and found a way to work around it? I'm logging out the browser version and seeing Chrome/120.0.6099.321Chrome/120.0.6099.321 , so maybe it's not headless (or it could be "new" headless, we're likely using old headless on ec2). Update I was able to hack this by using an evaluate call to set overflow hidden on html, but would love a better solution.

Brett Willis•12/10/24, 10:46 AM

Variables in the global scope can be shared only in the same instance of the same worker (think: same process on same machine). Not between different Workers (with different name).
This typically only occurs when multiple requests reach the same data center within a few seconds, then they may get routed to the same Worker instance.
