Firebase/NodeJS behind proxy server

Question

How do I run Firebase admin on NodeJS when the computer is behind a corporate proxy?

npm has already config proxy and https-proxy. npm commands executes alright.

Firebase however, tries to directly access the internet:

Error: Credential implementation provided to initializeApp() via the "credential" property failed to fetch a valid Google OAuth2 access token with the following error: "connect ETIMEDOUT 216.58.203.45:443".

I tried to update the faye-websocket\lib\faye\websocket\client.js under firebase-admin to read

  var Client = function(_url, protocols, options) {
  options = options || {};
  options.proxy = {
    origin: 'http://proxy.server.local:8080'
  };

I tried several variations, but nodejs is still trying to directly access 216.58.203.45:443. What else should I update to make it work?

This is how I run my FirebaseAdmin behind a corporate proxy.

Please install the latest Firebase Admin Node version, which is v6.4.0 and above. Besides, you also require to install a tunnel2 library.

npm install firebase-admin@6.4.0
npm install tunnel2


var admin = require('firebase-admin');
var serviceAccount = require('path/to/serviceAccountKey.json');
const tunnel = require('tunnel2')
// Create your Proxy Agent 
// Please choose your tunneling method accordingly, my case
// is httpsoverHttp, yours might be httpsoverHttps
const proxyAgent = tunnel.httpsOverHttp({
    proxy: {
      host: 'yourProxyHost',
      port: yourProxyPort,
      proxyAuth: 'user:password' // Optional, required only if your proxy require authentication
    }
});
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount, proxyAgent),
  databaseURL: 'https://<DATABASE_NAME>.firebaseio.com'
});
