google-apps-script Firebase and AppScript : Introduction Some more functions to implement read and write.

Example

1. To write a simple data to test whether connection is working or not.

function myFunction(){
 var firebaseUrl = "https://example-app.firebaseio.com/";
 var secret = "secret-key";
 var base = FirebaseApp.getDatabaseByUrl(firebaseUrl, secret);
 base.setData("test", "Hello Firebase"); 
}

2. To read all the Data

function getAllData() {
         var firebaseUrl = "https://example-app.firebaseio.com/";
         var secret = "secret-key";
var base = FirebaseApp.getDatabaseByUrl(firebaseUrl, secret);
 var data = base.getData();
          for(var i in data) {
            Logger.log(data[i].firstName + ' ' + data[i].lastName);
          }
}

  var secret = "secret-key";
  var base = FirebaseApp.getDatabaseByUrl(firebaseUrl, secret);
  var contact = base.getData("Yash-Udasi");
  Logger.log(contact);
}
