Plupload
Plupload es una librería de carga de archivos JavaScript que proporciona una interfaz estandarizada para gestionar transferencias de archivos a través de diferentes runtimes y entornos de navegador. Funciona como una interfaz y gestor de carga cross-browser, admitiendo selecciones de múltiples archivos y filtrado de archivos basado en el navegador.
La librería se distingue por sus capacidades especializadas para manejar grandes volúmenes de datos e integración en la nube. Incluye un gestor de carga de archivos fragmentados para dividir archivos grandes en partes más pequeñas y evitar los límites de tamaño del servidor, así como un procesador de imágenes en el lado del cliente para reducir el tamaño de las imágenes y eliminar metadatos antes de la transmisión. Además, actúa como un cliente de carga directa a S3, permitiendo que los archivos se envíen directamente a buckets de Amazon S3 utilizando políticas firmadas y claves de acceso.
El proyecto cubre una amplia gama de capacidades de gestión de carga, incluyendo soporte para arrastrar y soltar, filtrado de archivos personalizado por tipo MIME o extensión, y la capacidad de enviar datos binarios o parámetros multipart. También gestiona el tráfico a través de reintentos de carga fallida y admite solicitudes cross-domain mediante CORS o archivos de política.
Features
- File Upload - Provides a comprehensive JavaScript library for managing file selection and transmission across different browsers.
- Multi-Method File Uploads - Implements a comprehensive web interface for uploading multiple files via drag-and-drop and selection dialogs.
- Chunked Uploaders - Provides a mechanism to split large files into smaller binary segments to bypass server upload limits.
- S3 File Uploads - Implements client-side logic for sending files directly to Amazon S3 buckets using signed policies.
- Large File Uploads - Manages the transmission of oversized files by splitting them into chunks to bypass server limits.
- Runtime Abstraction Layers - Standardizes upload logic across HTML5, Flash, and Silverlight runtimes via a single abstraction layer.
- Cross-Browser API Standardizations - Standardizes file upload logic across different browser runtimes and environments using a single JavaScript API.
- Cross-Browser Upload Interfaces - Provides a standardized interface for managing file transfers across different browser runtimes including legacy fallback support.
- Direct-to-Cloud Uploads - Sends files directly from the browser to Amazon S3 buckets using signed policies and access keys.
- MIME Type and Extension Filters - Provides mechanisms to restrict files in the upload queue based on MIME type, file extension, or maximum size.
- File Type Restrictions - Limits which file types and sizes a user can add to the upload queue.
- Client-Side Compression - Downsizes and compresses images in the browser before upload to reduce bandwidth use.
- Binary Stream Uploads - Enables sending files as raw binary streams to servers that do not require multipart form-data.
- Upload Retry Mechanisms - Attempts to re-upload a file or chunk a specified number of times following an HTTP error.
- Multipart Form Uploads - Supports transmitting files and additional form parameters using the multipart/form-data standard.
- Custom Logic Filtering Hooks - Allows the creation of asynchronous validation rules to reject files based on custom logic or API checks.
- Upload Interface Customization - Provides pre-built components for implementing file selection and upload management interfaces.
- File Extension Filters - Restrict files selected via dialog or drag-and-drop based on file extensions and custom MIME type mappings.
- Bulk File Selection - Enables the selection of multiple files simultaneously from the system file dialog.
- File Upload Queue Widgets - Ships pre-built queue widgets and components to handle the visual flow of file transfers.
- Drag-and-Drop File Upload - Allows adding files or folders to the upload queue by dragging them from the desktop.
- Client-Side Resizing - Adjusts image dimensions in the browser before transmission to reduce bandwidth consumption.
- Metadata Stripping - Downsizes images and strips metadata headers before upload to reduce file size and save bandwidth.
- Image Resizing - Uses a browser canvas to resize images and reduce quality to save bandwidth before uploading.
- Client-Side Media Processors - Processes images in the browser to downsize and strip metadata before they are uploaded.
- Form Components - API for handling multiple file uploads and filtering.
- Form Components - Multi-runtime file upload API.
