jQuery File Upload is a mature, feature-rich jQuery plugin for handling file uploads in web browsers. It provides multiple file selection, drag & drop support, progress bars, client-side image resizing, preview functionality, and supports cross-domain, chunked, and resumable uploads. The architecture follows jQuery widget patterns with a modular plugin system that separates concerns into core functionality, processing pipelines, media handling, validation, UI components, and transport mechanisms. The code demonstrates sophisticated handling of browser inconsistencies and edge cases while maintaining a clean, extensible design.
This repository provides `react-photo-view`, a React component library for image and custom element preview with touch gestures, animations, and keyboard navigation. The library exposes three primary components: `PhotoProvider`, `PhotoView`, and `PhotoSlider`. `PhotoProvider` manages a group of images via React context, tracks visibility and index, and renders a `PhotoSlider` portal. `PhotoView` registers individual images or custom render nodes with the provider and handles thumbnail click/double-click triggers. `PhotoSlider` renders a full-screen overlay with a backdrop, swipeable carousel, zoom/pan/drag support, and optional toolbar/overlay customizations. The architecture is monolith-like within the library but decoupled through context and custom hooks. Key entry points are the `PhotoProvider` wrapper and `PhotoView` child components. External dependencies include React 16.8+ and ReactDOM. The codebase demonstrates strong craftsmanship: physics-based scrolling, debounced/tap gesture handling, and modular utility functions. No unit tests are present, and TypeScript version (4.9) and some dependency versions are slightly behind current, but the library is actively maintained and functional.
