Challenges faced when integrating Angular with Bootstrap elements

I am currently in the process of developing a website using Angular 12, and although it may not be relevant, I am also incorporating SCSS into my project. One issue that I have encountered pertains to the bootstrap module, specifically with components such as dropdowns, modals, and tooltips, which are essential for my site. To integrate the bootstrap module, I utilized the command 'npm install bootstrap'. Within my scripts array, the configuration is set up as follows:

"scripts": [ 
"node_modules/jquery/dist/jquery.slim.min.js", 
"node_modules/bootstrap/dist/js/bootstrap.bundle.min.js" ]

The specific code snippet for the dropdown component can be found at: https://getbootstrap.com/docs/5.1/components/dropdowns/

<div class="btn-group">
  <button type="button" class="btn btn-danger dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
    Action
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
    <li><hr class="dropdown-divider"></li>
    <li><a class="dropdown-item" href="#">Separated link</a></li>
  </ul>
</div>

Any assistance would be greatly appreciated.

Answer №1

Having duplicate imports of Popperjs is causing the issue, removing both popperjs and bootstrap.min.js imports will resolve the problem. Alternatively, you can follow the steps outlined below:

Here are the steps to use Bootstrap in Angular:

  1. Firstly, install Bootstrap by running the following command:

    • npm install bootstrap --save

  2. Next, in your angular.json file:

    • Within the styles array, import bootstrap.min.css like so:

      • "node_modules/bootstrap/dist/css/bootstrap.min.css"

    • Within the scripts array, import the bootstrap.bundle.min.js file which includes popper.js. If you only import bootstrap.js, make sure to include popper.js before it. For more information, refer to the Bootstrap Docs.

      • "node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"

For Jquery Integration:

  1. If you also want to use jQuery, ensure that you import jQuery before bootstrap.bundle.min.js.

  2. Install jQuery types from npm using the following command:

    • npm install --save @types/jquery

  3. In your angular.json file, import jQuery as follows:

    • "node_modules/jquery/dist/jquery.min.js"

  4. In the tsconfig.app.json file, add jQuery type under compilerOptions:

    • "types": ["jquery"]

  5. You can then use the famous $ variable for jQuery.

  6. Enjoy utilizing jQuery with Bootstrap!

UPDATE:

If you're working with SCSS, import Bootstrap SCSS files in the styles array instead of CSS files.

In your angular.json file, within the styles array, import the Bootstrap SCSS files using:

node_modules/bootstrap/scss/bootstrap.scss

In Angular, components are generated dynamically, meaning that scripts designed to manipulate elements on page load will not automatically function when incorporated into Angular templates.

If you're looking to integrate Bootstrap with Angular, there are numerous libraries available for this purpose. One popular option is .
