What could be the reason for the malfunction of Bootstrap Js in my template?

This question focuses on understanding how something works rather than just fixing it. I really enjoy learning about this.

Currently, I am involved in a project that combines VueJS and Symfony. One of the things I would like to achieve is using Bootstrap JS components such as collapse.

I have imported Bootstrap into my application and verified its presence in my file.

//app.js
import $ from 'jquery'
window.$ = window.jQuery = $
import 'bootstrap'

if (typeof $.fn.popover == 'function') {
    alert('yolo') //works
}
//My view
{% block javascript %}
    {{ parent() }}
    <script>
        if (typeof $.fn.popover == 'function') {
            alert('yolo') //works
        }
    </script>
{% endblock %}

However, simply importing Bootstrap is not enough to achieve the desired functionality in my view. For example, the attribute-related method does not work.

<!-- This does not work -->
<div id="accordion">
    <div class="card">
        <div class="card-header" id="headingOne">
            <h5 class="mb-0">
                <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
                    Collapsible Group Item #1
                </button>
            </h5>
        </div>

        <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
            <div class="card-body">

            </div>
        </div>
    </div>
</div>

After some research, I discovered there is a library (which I cannot use due to extensive refactoring required) that addresses this issue. Is there a specific reason for this?

How does it work? Could webpack loader be the reason behind this? (I am using Webpack Encore)

Answer №1

It appears that you may have forgotten to include all of the CSS components, as there are no errors showing in your console.

Have you double-checked to make sure that you have imported the necessary CSS files?

@import "~bootstrap/scss/xxx";

If you are using SCSS, this step is crucial.
