How to set Node.js global proxy setting?

To set Node.js global proxy setting, we use the global-tunnel-ng package.

For instance, we write

const globalTunnel = require("global-tunnel-ng");

globalTunnel.initialize({
  host: "10.0.0.10",
  port: 8080,
  proxyAuth: "userId:password",
  sockets: 50,
});

to call initialize with an object with the proxy options and credentials to connect to the proxy.
