Use Proxy with Fetch

[Singey32]

Problem

I'm unsure about how to use a proxy with fetch. I've found very little documentation about how to integrate a proxy and I seek to use separate proxies for any fetch request with username and password authentication if applicable.

Solution

As for a good solution I'd hope for a code example to perform a simple get request to a site (e.g. to ifconfig.me) using a proxy and instructions on how to include a username and password with that proxy.

Possible with #1411, but if you are using fetch from node directly, you may need to wait for nodejs/node#43187 (if a decision to expose it is ever made).

If you are on node.js v18.2.0 or higher, you can also use node's fetch.

import { fetch, ProxyAgent } from 'undici'

const agent = new ProxyAgent('localhost:8888')

const response = await fetch('https://example.com', {
    dispatcher: agent
})

TIPs: const agent = new ProxyAgent('localhost:8888') is not working (for me), remember to add http:// protocol.
