Uncaught ReferenceError: firebaseui is not defined

The website does not display anything. It gives the error: firebaseui not defined. I am running my code in eclipse, on my localhost web server. The error is displayed in "app.js" file of a sample web application I took from github. The output must show sign-in widgets.

var ui = new firebaseui.auth.AuthUI(firebase.auth());
Solution

  • Add this into the HTML page's <head>, because firebaseui.js defines the missing firebaseui:

    <script src="https://cdn.firebase.com/libs/firebaseui/3.5.2/firebaseui.js"></script>
<link type="text/css" rel="stylesheet" href="https://cdn.firebase.com/libs/firebaseui/3.5.2/firebaseui.css" />

    This must be loaded before the app.js is being loaded, so the it won't be undefined anymore.
