I was checking Service Workers, it is mentioned in ES Modules. Thank you so much!

Is it possible to get amount of written bytes to the client in worker?

In the Response body, maybe. For the entire Response, no, since some of the Response body is written in later stages that are not accessible to the Worker.

I'm trying to reverse proxy from bucket storage to client and I want to know how much bytes it is written to the client so I can deduct the fee from their balance. I assume the only way here would be to clone the response to bucketstorage first, read the content-length, inform the backend, and then return the response. The only risk is that maybe the connection dies on user's side in the middle of the download.

If you are fetching directly from bucket storage, then you should be able to read the

content-length

without cloning the

Response

Yeah good point!

I am trying to calculate if bundled or unbound is cheaper (to send a mail using MailChannels). I only do that in the worker call. I saw that its 0.178 GB-s duration. If I calculate it, it seems like bundled is still cheaper. Or am I doing the calculation wrong? I calculated based on that duration that 1M calls using unbound would be $2.37 while bundled would be $0.5

unless you're doing like 10 mil+ requests all under 225ms, Bundled will be cheaper

yeah I told that to the client. Whats 225ms? is that the GB-s? that isnt a factor when doing bundled right

225ms of either wall time or 8x CPU time

and no, doesn't matter for Bundled, just unbound

is wall time GB-s or is that something different... because I count not find wall time in the cloudflare stats

wall time just means like actual time, like if you look at a clock

(which may be GB-s yes - assuming it's more than the multiplied CPU time)

aaah... awesome. I learned something new 🙂

Unbound billing is sadly quite confusing

Switching our traffic from pointing to Vercel functions to Cloudflare workers in the next 8 weeks (for our own and clients)... 140 million requests a month... Vercel costs: $5600 Cloudflare costs: $70 First things are switched and its already 20% faster...

yeah, but its still great that its there for when needing longer processes

Oh wow, that is quite the saving!

yeah... I was really skeptical about the pricing at first... looked like there was a catch somewhere... but then I understood that vercel is also build on top of cloudflare... they just add a margin on top 🙂

Using CF Access I think it’s possible, but the docs for how to do it seem to have gone missing. https://blog.cloudflare.com/using-your-devices-as-the-key-to-your-apps/

How does one users a library like

sequalize

in a worker? I get all shorts of "cannot resolve" X package

i want to implement some geolocation security based on the user's country/region? the country & region should be 99.99% of the time accurate compared to the city which might differ on every request, right?

do you bundle your code?

It's basically a giant user (or company) maintained database.

There are inaccuracies every now & then.

yeah but how accurate are the region and country field?

It depends on the accuracy of the GeoIP data. It is generally correct for regular users, but server-bounded apps may use Anycast IPs, which may be wildly wrong.
