Use Custom DNS resolver for any request in NodeJS

0 votes

I'm looking to find a way to use a custom DNS resolver for a nodejs request using node-fetch. I think there is a star of explaining here : Node override request IP resolution but I can't manage to make it work for any request. My goal is to use an alternative DNS resolver, such as cloudflare (1.1.1.1) or Google public DNS (8.8.8.8) instead the OS / ISP default DNS resolution.

import http from "http";
import https from "https";
import fetch from "node-fetch";

const staticLookup = (ip: string, v?: number) => (hostname: string, _: null, cb: Function) => {
  cb(null, ip, v || 4);
};

const staticDnsAgent = (scheme: "http" | "https", ip: string) => {
  const httpModule = scheme === "http" ? http : https;
  return new httpModule.Agent({ lookup: staticLookup(ip), rejectUnauthorized: false });
};

// Both request are not working
fetch(`https://api.github.com/search/issues?q=Hello%20World`, {
  agent: staticDnsAgent("https", "1.1.1.1")
})

fetch(`http://jsonplaceholder.typicode.com/todos`, {
  agent: staticDnsAgent("http", "8.8.8.8")
})

I'm struggling a bit to find a way to make this example work, I'm pretty sure I have to use the nodejs DNS module and set a custom server.
