Did you use

wrangler dev --remote

wrangler dev --remote

before? Then the code runs in a CF datacenter and has access to the remote KV store.

As documented it should use a local store to not affect prod data when using local mode (the default):

now again getting some different issue, btw my namespace name 'cred'

kev-ac•7/26/24, 1:21 PM

Its a safeguard to not overwrite prod data by accident. In dev mode wranlger looks for a key "preview_id" in wrangler.toml. Either copy your KV id or create a new one as described in the error message (which is the recommended way)

K

kev-ac•7/26/24, 1:23 PM

So like this:

kv_namespaces = [
    { binding = "<YOUR_BINDING>", id = "<YOUR_ID>", preview_id = "<YOUR_ID>" }
]

kv_namespaces = [
    { binding = "<YOUR_BINDING>", id = "<YOUR_ID>", preview_id = "<YOUR_ID>" }
]

kv_namespaces = [
    { binding = "<YOUR_BINDING>", id = "<YOUR_ID>", preview_id = "<YOUR_ID>" }
]

kv_namespaces = [
    { binding = "<YOUR_BINDING>", id = "<YOUR_ID>", preview_id = "<YOUR_ID>" }
]

hey wanted to run something past the group to see if anyone has tried something similar or if i'm on my own here. everything in me tells me this should be possible, maybe using service workers as the app/api proxies but i haven't worked with them before... ideally this would be possible without using redirects to different domains, maybe using some form of rewrites but i don't know honestly. i'll post results here after i play around with it a bit!

caz•7/26/24, 2:21 PM

good point! i would say though one thing i was considering was when someone hits "/" i would like if the proxy could do an auth check and then the spa would take over if it passes, otherwise render the honox app. that's one reason i considered breaking it up into different workers at least

C

caz•7/26/24, 2:22 PM

currently everything is already hosted in it's own workers/projects at different domains which is fine, just more or less doing a thought experiment i guess?

kian•7/26/24, 4:23 PM

I assume so, but also means you can't fetch proxied hostnames anymore

K

kian•7/26/24, 4:24 PM

(well, assuming the callout in the docs is still accurate)

Currently, mTLS for Workers cannot be used for requests made to a service that is a proxied zone on Cloudflare. If your Worker presents a client certificate to a service proxied by Cloudflare, Cloudflare will return a 520 error.

Kkian I assume so, but also means you can't fetch proxied hostnames anymore

Does it make sense to use workers to host a chat endpoint? Not a peer to peer chat but a chat between a human and a model (the actual model is hosted elsewhere and the worker would just make a request to open ai or whatever and relay the results back to the client).

I ask cause with a serverless endpoint like workers you’re constantly spinning up and shutting down resources with each message. Since there will be so many, does it make sense to use server-less here? Or should I I look into a persistent connection?

Also if workers isn’t the right tool for the job, is durable objects the one I should be using?

Chain the fetch with .then((r) => r.json()).then(console.log) and you’ll have the output of what discord sent back

dashboard is very handy if we are not in the work desk and willing to modify some variables that can change the behaviour of service. But its not working as expected

H

quick question, can I use workers as a basic backend service to my current domain?

H

h•7/28/24, 1:40 PM

basically a proxy to avoid exposing api keys and sensitive info

E

Erisa•7/28/24, 1:47 PM

yeah, you can

but when i write new data with put() it also writes on dashboard's namespace
