Hi everyone, why I can't use mtls_certificates binding without

--remote

--remote

?

I created a brand new cf worker project with the following tutorial: https://developers.cloudflare.com/workers/get-started/guide/#1-create-a-new-worker-project
I added the mtls certificate like the following tutorial: https://developers.cloudflare.com/workers/runtime-apis/bindings/mtls/#client-authentication-with-mtls

When I run the command

wrangler dev

wrangler dev

the binding

environment.MY_CERT

environment.MY_CERT

environment.MY_CERT

environment.MY_CERT is

undefined

undefined

.

But when I run the command with remote like

wrangler dev --remote

wrangler dev --remote

wrangler dev --remote

wrangler dev --remote the binding starts to work.

I mean, you can define ranges in the get from r2 can't you?

Erisa•6/17/24, 4:09 AM

Hm but the cache api should handle ranges itself after you cache the full file

Erisa•6/17/24, 4:09 AM

This code works fine with ranges https://github.com/kotx/render/blob/master/src/index.ts

Erisa•6/17/24, 4:10 AM

I would link to a specific line but the range handling is scattered around

Ppeshakoo i took a look and it looks like they are inserting the range in the get, not fro...

Erisa•6/17/24, 4:18 AM

Well the cache just reads the range headers in the request object you passed it and returns the right slice so you don't need any code for it

Erisa•6/17/24, 4:19 AM

I think what render doesn't do is insert the full file into cache when asked for a range, but you could do that instead if it suits your case

Erisa•6/17/24, 4:52 AM

The docs imply that it should extract it from the headers of the request

Erisa•6/17/24, 4:52 AM

and when I tested render that did seem to be the case

Howdy y'all.
I've been recently trying to build some jobs with the scheduled() worker and have a few questions..

So far I've just been testing locally and whenever I run into failures, it just fails silently.
What's the proper way to error handle in a scheduled function?
With local testing, I usually just log out the error but that doesn't seem to work here.

Is it necessary that I use ctx.waitUntilctx.waitUntil whenever I log out?
Do I need to wrap the entire scheduled job in waitUntil or just the bits I want to await?
And how does logging work once deployed? Do I need to log to tail?

And are scheduled jobs ever meant to return anything?

Hi everyone,
I’m looking for advice on how to serve two different codebases (both static frontends) from the same domain (using workers or pages) while maintaining this URL structure:

• example.com - Main webpage (codebase 1)
• example.com/:username/:slug - User-specific dynamic pages (codebase 2)

Can anyone share best practices or examples on how to set this up, especially concerning configuration and routing? Any help would be greatly appreciated!

I would install

cloudflared

cloudflared

and use cloudflared --url http://localhost:8787cloudflared --url http://localhost:8787, it will give you a public url

Erisa•6/17/24, 5:18 PM

you can even use that to run on domains in your account if you cloudflared logincloudflared login and add --name sometunnelname --hostname somedevsub.example.com--name sometunnelname --hostname somedevsub.example.com

awesome, thanks. I think i just need it while dev'ing locally sine i can just use my published url from CF when i deploy.

I just thought from memory there was a way of previewing workers that published a preview URL but couldnt figure it out

johtso•6/17/24, 5:32 PM

is it possible to have multiple versions of a worker deployed?

johtso•6/17/24, 5:32 PM

like referencing a unique version of a worker using a url

johtso•6/17/24, 5:33 PM

and being able to continue using the old version after deploying a new version

np, and no there isnt that but cloudflared is easy enough and also a cloudflare product

How can one local worker access both local and remote D1 databases? I can't seem to find the local

database_id

Is it possible to build an uptime/latency checker using cloudflare workers?
I'm specifically interested whether it's possible to check non-cloudflare server latency from different locations around the world i.e. making worker ping an endpoint from specific location of choosing?
If not, is there a cloudflare product family that would be able to do that?

Ppeshakoo definitely possible. You can use cron workers and (maybe) durable objects (i thi...

q_p•6/18/24, 6:56 AM

I understand that theoretically it's possible, but I wasn't able to find any cloudflare documentation about how to specify in which location my worker runs.
e.g. one worker in USA, one in Europe, one in Asia

SteffTek•6/18/24, 6:57 AM

workers run closest to the origin of the request, so if im in europe, my worker (probably) won't run in the freedom states
