requirements needed for Bootstrap's image slider

When using just the Carousel functionality in JavaScript, which dependencies need to be included excluding `bootstrap.js` but including necessary code for Carousel (`carousel.js`, ...)?

As per the docs, the setup code is:

var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel)

The error message 'Uncaught ReferenceError: bootstrap is not defined' indicates that the Bootstrap 5 part is missing.

I have searched through Bootstrap's official documentation and other sources but could not find this information.

Answer №1

If you want to avoid errors, make sure to include the bootstrap bundle.

Be sure that popper, jquery, and bootstrap(.min).js are included in your code.

Here is an example of how to include it:
