`How can I add external JavaScript files to an Angular template?`

On my index.html page, I have a form that utilizes an external javascript:

<script src="https://js.braintreegateway.com/v2/braintree.js"></script>
<script>
var clientToken = removed
braintree.setup(
          // Replace this with a client token from your server
          clientToken,
          "dropin", {
            container: "payment-form",
            form: "checkout"
          });
</script>

Prior to integrating this page with Angular, I made sure it was functioning correctly. After making it an angular state using $stateProvider:

 .state('billing', {
        url: '/billing',
        views: {
            'main': {
                controller: 'BillingController as billingCtrl',
                templateUrl: '/billing/index.html'
            }
        }
    });

When routing to the new page, I encountered these errors:

I prefer not to use third-party libraries like braintree-angular. It appears that the Angular template does not recognize the <script> tags because they are used to bind controllers to the HTML.

Answer №1

To effectively include a JavaScript file in Angular.js, follow these steps:

  1. Begin by creating a 'scripts' folder within the assets directory for improved organization
  2. Place your JavaScript file inside this newly created folder
  3. Locate and open the angular.json file at the root of your Angular project
  4. Add the path to your JavaScript file to the scripts key as shown below:

{
  "projects": {
    "replace-with-your-project-name-here": {
      "architect": {
        "scripts": ["src/assets/scripts/myScriptsFile.js]
      },
      ....
}

Answer №2

In the build process, an index.html file was being generated that consolidated all assets, including js/controller files. To incorporate an external js file, I simply added my script tag to the index.html file along with all the dependencies.
