const express = require('express')
const firebaseAuth = require('express-firebase-authenticate')

admin.initializeApp()

const app = express()

// Add middleware
app.use(firebaseAuth)

// Handle POST request to the "widgets" Firebase function
app.post('*', async (req, res) => {
  // ... your firebase function code here

  // You will have access to the decoded token at 'req.user'
  // For example...
  console.log(req.user.uid)

  res.sendStatus(200)
