title: firebase.storage is not a function error using node.js
body: <p>I am looking to upload an image to firebase storage, the service is still running and not deprecated, I don't want to use google-cloud, how I am supposed to solve that?</p>
  
  <p>All other posts suggest gcloud</p>
  
  <p>I was able to use realtime database but no luck with storage</p>
  
  <pre><code>var firebase = require('firebase  ');
  app.use(express.static('public'))
  
  var config = {
      apiKey: "xxxxxxxx",
      authDomain:  "xxxxxxxx",
      databaseURL:  "xxxxxxxx",
      projectId:  "xxxxxxxx",
      storageBucket: "xxxxxxxx",
      messagingSenderId:  "xxxxxxxx",
  };
  firebase.initializeApp(config);
  
  app.get('/home', (request, response) =&gt; {
    var storageRef = firebase.storage().ref('/master/'+file.name);
    fs.readFile('public/test.png', function(err, data) {
      if (err) throw err;
      storageRef.put(data);
    });
  })
  </code></pre>
