How to use ProxyAgent and CookieAgent at the same time?

[ickg5]

Hey folks, greetings 👋
I now need to use ProxyAgent and CookieAgent at the same time, I don't know how to write.
I don't see anything about this in the documentation.
Please help me.

My example code goes something like this:

import { ProxyAgent, request, setGlobalDispatcher } from "undici"
import { CookieAgent } from "http-cookie-agent/undici"
import { CookieJar } from "tough-cookie"


async function test() {
  const proxyAgent = new ProxyAgent("http://127.0.0.1:10810")
  setGlobalDispatcher(proxyAgent)
  const jar = new CookieJar()
  const agent = new CookieAgent({ cookies: { jar } })
  await request("https://test.com", {
    dispatcher: agent,
  })
}

Help would be greatly appreciated! 🙏

While we are at it, is setting the global dispatcher the only way to do this? I would like to change some settings but I want those changed settings to be just for that one request, not for all subsequent requests. I see I can set a dispatcher in the options. Would I need to create a new Agent({}) and set it in options? Would I leak agents this way (do I need to dispose of them later)?

I would recommend you reusing them whenever possible. Note that you can also call agent.request() and skip the option.

Ultimately no, but some sockets would linger around until they timeouts. I would recommend reusing them or destroying them.

Perhaps I should open a new question :-).

OK, so what I can do is create a new Agent as a global variable, call it 'selfSignedDispatcher', set the connect to rejectAuthorized: false, and set it as a dispatcher for calls that use self-signed certificates. Thus I would only use either default global dispatcher or the one I created for reuse.
