db queries also take a suprising 200ms from what ive tested but thats still way too long for just uploading files to r2 right?

has anyone successfully crated / uploaded a worker via the CF API using nodeJS? I can't seem to get the formBody stuff to work right when uploading the worker, I would greatly appreciate it.. Thank you

Have you looked at what wrangler does? That's built for nodejs

J

James•5/5/23, 6:36 PM

Yes you should have no issues with that

rob•5/5/23, 7:37 PM

yes i've used wrangler. but im trying to create a worker programattically, from another worker

R

rob•5/5/23, 7:37 PM

so one worker that can generate another one, I tried followinf the API docs but getting hung up with the formData format

Z

zegevlier•5/5/23, 7:43 PM

I have a very rough version of uploading a worker from another worker. It mostly consists of code copied from Wrangler. If you want I can DM that to you

rob•5/5/23, 8:40 PM

yes please, that would be amazing.

I wonder if #workers-for-platforms has a diff endpoint or way of doing it on their end for if you're managing yur customer's workers etc.. need to talk to someone at Cloudflarer about that

yeah errr my bad , I worded that wrong. I meant like, their function goes into a worker, on my loudflare workers for platforms account etc

Is there any way to schedule a task inside cloudflare workers? Like call my worker after 48 hours or one date/time x?

Sounds like Durable Object alarms might be what you want?

Hi, do you have any dependencies that handle crypto? createHmac should be available natively under

you don't really need an SDK to call an API, could you just call it directly? personally I avoid SDKs whenever feasible in favor of some simple fetch calls

sathoro•5/19/23, 12:05 PM

lmao

calling an SDK is usually as simple as calling fetch if the API is not overcomplicated

S

you are really incorrect here. you should have simply asked how to create an hmac. instead you complicated things by talking about an SDK. I just did this last week for an API...
