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

zegevlierOP•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

R

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?

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

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

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...

If you just need caching you don't need to use workers at all. You can just proxy the site through cloudflare and it should cache things like images automatically
