"Trouble in paradise: Angular.js fails to make a lasting impression

As a beginner in Angular, I am attempting to create a simple Hello World application. Below are my source files:

<html >
  <head>
    <script src="./node_modules/angular/angular.js"></script>

    <title>ngClassifieds</title>
  </head>
  <body ng-app="ngClassifieds">
    <div>
      <label>Name:</label>
      <input type="text" ng-init="yourName = 'oie'" placeholder="Enter a name here">
      <hr>
      <h1>Hello {{yourName}}!</h1>
    </div>
  </body>
</html>

..\ngClassifieds\scripts\app.js

angular.module("ngClassifieds",[]);

The current file structure (generated using npm) is as follows:

└───ngClassifieds
    │   index.html
    │   package.json
    │
    ├───css
    ├───node_modules
    │   ├───angular
    │   │       angular-csp.css
    │   │       angular.js
    │   │       angular.min.js
    │   │       angular.min.js.gzip
    │   │       angular.min.js.map
    │   │       bower.json
    │   │       index.js
    │   │       LICENSE.md
    │   │       package.json
    │   │       README.md

I am encountering the following issues:

  1. If I specify ng-app as ng-app="ngClassifieds" in the index.html file, Angular ceases to function correctly (see output below)
  2. Using \ngClassifieds\node_modules\angular\angular.js instead of https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js results in failure (see output below)

Error: https://i.sstatic.net/RKx4f.png

However, when I remove the ng-app attribute and utilize https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js, the application functions as expected:

https://i.sstatic.net/E9oZ7.png

This is the revised index.html:

<html >
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>

    <title>ngClassifieds</title>
  </head>
  <body ng-app>
    <div>
      <label>Name:</label>
      <input type="text" ng-init="yourName = 'oie'" placeholder="Enter a name here">
      <hr>
      <h1>Hello {{yourName}}!</h1>
    </div>
  </body>
</html>

Answer №1

It appears that the module was defined but not included in the file, resulting in an error due to the missing ngClassifieds. To resolve this issue, simply include your app.js file in the header section after angular as shown below:

<html>
  <head>
    <script src="./node_modules/angular/angular.js"></script>
    <script src="/ngClassifieds/scripts/app.js"></script> <!-- Include it here-->
    <title>ngClassifieds</title>
  </head>
  <body ng-app="ngClassifieds">
    <div>
      <label>Name:</label>
      <input type="text" ng-init="yourName = 'oie'" placeholder="Enter a name here">
      <hr>
      <h1>Hello {{yourName}}!</h1>
    </div>
  </body>
</html>

EDITED

The issue was resolved by correcting the path to the app.js file. Once the correction was made, everything worked smoothly.
