I'm using Swiperjs in my website. Today I saw that swiper is not working, and in console were 404 errors, because css and js files could not be found.
I am using swiper from CDN, in the way that is written on swiperjs website https://swiperjs.com/get-started/
Now the problem: when I developed my website, there was a different url to swiper CDN (writen in swiperjs website, last year). In my code, before, was this, and it worked:
<link rel="stylesheet" href="https://unpkg.com/swiper/css/swiper.min.css">
<script src="https://unpkg.com/swiper/js/swiper.min.js"></script>
Today, this code gave me errors. So I changed to:
<link rel="stylesheet" href="https://unpkg.com/swiper/swiper-bundle.min.css">
<script src="https://unpkg.com/swiper/swiper-bundle.min.js"></script>
And this now works.
My question is:
how can I be sure that in future there won't be any changes like this? Am I more safe if I download these scripts and include them in project?
I thought that CDN should always work.
