Gallery
Gallery is a JavaScript library for creating responsive media galleries. It provides touch-enabled lightbox views and carousels for displaying collections of images and videos across different web browsers.
The library distinguishes itself through a factory-based rendering system that supports diverse content types, including local video playback, external video embedding, and custom HTML content. It features an input-agnostic navigation controller that maps swipe gestures, mouse clicks, and keyboard presses to a single state machine.
The project covers high-level capabilities including automated slideshow playback with timed transitions, responsive image delivery based on screen resolution, and on-demand lazy loading of high-resolution media. It also includes a programmatic API for managing gallery state and a set of lifecycle hooks for executing custom logic during transitions.
