6 JavaScript/jQuery plugins I use in almost every project.

The list:

Zoom

Photoswipe (http://photoswipe.com/)

Intuitive touch gestures. Works on all tested devices by me (iOS and Android). Just a little bit harder to convince the back-end developers to send you the real image size to get setup going.

Modals/Lightbox

Magnific Popup (http://dimsemenov.com/plugins/magnific-popup/)

Anything you’ll ever need from a modal plugin (Inline, ajax, videos, maps, images). As photoswipe, this plugin is created by Dmitry Semenov — Thank you for all the great work!

Form validation

Parsleyjs (http://parsleyjs.org/)

Easy to integrate, simple API, internationalization and very good UX.

Infinite scroll

Infinite AJAX Scroll (http://infiniteajaxscroll.com/)

History, Masonry + many more options to get you up and running in no time.

Lazy loading

Lazy load XT (https://github.com/ressio/lazy-load-xt)

If you don’t want to load the entire content as the plugin above does, maybe it’s a good idea to lazy load the images at least. This plugin works great both on mobile and desktop and it has a really simple API.

Carousel

Owl Slider (http://www.owlcarousel.owlgraphic.com/)

Works really nice on mobile and on large screens and you can customize the number of items based on custom breakpoints.

Any other plugin you use in your projects often?
