Basic application - angular has not been declared

I'm currently diving into the realm of javascript and angularjs, following along with the tutorials on .

After setting up a basic IntelliJ javascript project, I created two essential files:

index.html

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>My Angular App!</title>
        <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js"></script>
        <script src="app.js"></script>
    </head>
    <body ng-app="HelloWorld" ng-controller="MainCtrl">
        <div>
            {{test}}
        </div>
    </body>
</html>

and app.js

var app = angular.module('HelloWorld', []);

app.controller('MainCtrl', [
  '$scope',
  function($scope){
    $scope.test = 'Hello world!';
  }]);

However, I keep encountering "ReferenceError: angular is not defined" when trying to run the program. Despite my efforts, I haven't been able to solve this issue. Most recommendations suggest checking the order of script tag declarations, but I believe it's properly set in my case. Any guidance for a novice like me?

Unfortunately, I don't have the privileges to comment directly, so I'll share my thoughts here instead.

In reference to what yarons mentioned, it's advisable to utilize developer tools in your browser (excluding IE), and monitor the console output both in the browser and where your Node application is running.

Here are two recommendations:

  1. Make sure the dependencies in your application are configured correctly. Check the package.json file for any angular tags and verify if there are any version conflicts.
  2. Copy the specified files from /node-modules/angular to /public/libs/angular, then update the script references in your index.html to include:
    • angular.min.js
    • angular.min.js.map
    • angular-csp.css

<script type="text/javascript" src="libs/angular/angular.min.js"></script>

It's worth noting that while using CDN for libraries is common practice, sometimes keeping them stored locally can be beneficial...
