npm install firebase-admin-proxy --save

const caw = require("caw");
const https = require("https");

// Your Proxy
const firebaseAgent = caw("http://127.0.0.1:8118", {
  protocol: "https",
});

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://YOURAPP.firebaseio.com",
  agent: firebaseAgent, // proxy agent
  logging_enabled: true, // open logging info
});

If logging_enabled is open, your console will print out a similar log:

Firebase provides the tools and infrastructure you need to develop your app, grow your user base, and earn money. The Firebase Admin Node.js SDK provides admin (second-party) access to several Firebase services.

For more information, visit the Firebase Admin SDK setup guide.

The Firebase Admin Node.js SDK is available on npm as firebase-admin:

$ npm install --save firebase-admin

To use the module in your application, require it from any JavaScript file:

var admin = require("firebase-admin");

If you are using ES2015, you can import the module instead:

import * as admin from "firebase-admin";
