This is an experimental library and is not supported by Firebase
$ npm install mockfirebasevar MockFirebase = require('mockfirebase').MockFirebase;$ bower install mockfirebase<script src="./bower_components/mockfirebase/browser/mockfirebase.js"></script>MockFirebase supports the normal Firebase API plus a small set of utility methods documented fully in the API Reference. Rather than make a server call that is actually asynchronous, MockFirebase allow you to either trigger callbacks synchronously or asynchronously with a specified delay (ref.flush).
