How can I configure deno to use a socks5 proxy?

[justinmchase]

I am attempting to connect with a tls socket to a kafka server, but I need to go through a socks5 proxy to do it.

I'm trying to use HTTPS_PROXY=localhost:50000 deno run -A index.ts

The localhost:50000 port is actually a kubectl port-forward ... command to a pod running a socks5 server. I know this works because I can use it to connect to other things, I'm just trying to write a deno script to automate some stuff and have it go through that port. So I'm just curious if how I can do socks5 proxying with Deno?

I think what youre looking for is Deno.HttpClient https://deno.land/[email protected]?unstable&s=Deno.HttpClient. It essentially is deno's option bag for server specific features that can be added on to the browser's fetch api. For your example, I believe something like this could work:

const client = Deno.createHttpClient({
  proxy: {
    url: Deno.env.get('HTTPS_PROXY') ?? 'socks5://127.0.0.1:5000'
  }
})
const req = await fetch('https://myserver.com', { client })

[edit] this is a more useful doc link https://deno.land/[email protected]?unstable=&s=Deno.createHttpClient

Yeah but the socket is not http, its a tls connection, its own protocol. The server is kafka.

I see this library:
https://deno.land/x/socks5

But it does not implement a connectTls version of the proxy...

It seems like the tls connection itself should have some proxy options right on it though, is that not the case?

Im having the same issue except i get createHttpClient is not a function!

@ebrahimkarimi you may need to pass --unstable to your deno command
