About

This image swiper/slider/carousel library, written in TypeScript, aims to provide a high-performance slider best used when having many instances on a page (e.g. list of cards where each card has a swiper gallery - like Airbnb or hometogo).

Virchual uses virtual slides to only render visible slides. No unnecessary DOM elements.
