Why is Bootstrap Js not working in my template?

Asked by At

This is a question about how does it works more than how to fix it. I realy like to understand this.

So I'm working on a VueJS/Symfony project. And one of the thing I want to do is to use the bootstrap js component like collapse for exemple.

I do import bootstrap within my app and check if it is imported in my file.

import $ from 'jquery'
window.$ = window.jQuery = $
import 'bootstrap'

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

However this is not sufficient enough to make it work like I want on my view. For exemple the attribute related method will 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

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

By searching a bit I found out there is a library (I cannot use due to too much refactory work) which is doing this. Is there a specific reason ?

How does it works ? Is it due to webpack loader ? (I'm using Webpack Encore)
