How do I set the snapshot value to a $scope variable

[chris...@cwtinteractive.com]

// Books Controller
var databaseRef = firebase.database().ref('books');

$scope.allBooks = function() {
    bookRef.on('value', function(snapshot) {

        var data = snapshot.val();

        return data;

    }

};

I am trying to set the $scope.allBooks variable to an array of objects containing all of the books in the 'books' node. Can anyone help me with this?

You can't return a value from an asynchronous method. Read more here.

Considering that you're struggling with asynchronous concepts here, the best option might be to use a library like AngularFire (for Angular 1.x) or AngularFire2 (for Angular 2.x) to manage these things.

If you're determined to try this out yourself, the Stack Overflow link above on async should be considered required reading, and probably contains enough examples to help you through this.
