Angular File Upload
This project is a file upload module designed for the AngularJS framework, providing a comprehensive system for managing file selection, validation, and asynchronous transmission. It enables developers to build interactive web interfaces that capture local files through standard inputs or drag-and-drop zones, facilitating the entire lifecycle of a file transfer from initial selection to server-side upload.
The library distinguishes itself through its focus on cross-browser consistency and granular control over the upload process. It includes an automatic fallback mechanism that routes data through hidden frames when modern transport APIs are unavailable, ensuring functionality across legacy browser environments. Furthermore, it provides a robust queue-based orchestration system that allows for batch processing, real-time progress tracking, and the application of custom validation filters to enforce data constraints before transmission.
Beyond core transfer capabilities, the library offers tools for client-side media handling, such as generating image thumbnails for user verification prior to upload. Developers can also configure individual HTTP request settings, including custom headers and authentication credentials, to integrate with diverse server-side architectures.
Features
- AngularJS File Uploaders - Implements file upload functionality within AngularJS applications with support for drag-and-drop and progress tracking.
- AngularJS File Upload Modules - Provides a library for managing file selection, validation, and asynchronous HTTP uploads within the AngularJS framework.
- Upload Progress Tracking - Provides real-time monitoring of data transmission progress for individual files and batch uploads to the server.
- File Upload Constraint Validation - Enforces custom validation filters on file size, type, and content before files are added to the upload queue.
- Batch Upload Workflows - Manages the lifecycle of multiple file transfers by organizing items into queues and monitoring individual progress.
- Task Queues - Manages file transfer lifecycles by organizing individual items into a sequential or parallel processing pipeline for server transmission.
- Upload Request Configurations - Allows developers to define custom headers, methods, and authentication credentials for individual file uploads or batch transmissions.
- Iframe-Based Upload Fallbacks - Maintains compatibility with legacy browsers by routing file data through hidden frames when modern transport APIs are unavailable.
- Browser File Management - Provides interactive web interfaces that allow users to select, validate, and preview local files before transmitting them to a remote server.
- File Selection Interfaces - Provides interactive file selection inputs and drag-and-drop zones to collect user files for subsequent processing and transmission.
- Upload Constraints - Defines operational limits on file quantities and drop zone behavior to govern incoming data flow.
- Drag-and-Drop File Upload - Enables drag-and-drop file uploads by defining interactive zones that accept files from the local file system for immediate processing.
- Queue Management - Manages file transfer lifecycles by organizing files into a managed queue, enabling sequential or parallel transmission and batch status tracking.
- Blob-Based Preview Generators - Generates local image thumbnails using browser-native object URLs for visual verification.
- Browser Compatibility & Utilities - Maintains consistent file transfer functionality across modern and legacy browsers by switching between native transport methods and fallback techniques.
- Legacy Browser Support - Ensures consistent file transfer capabilities across older web browsers by automatically falling back to iframe-based techniques.
- Event-Driven Progress Tracking - Hooks into low-level data transfer streams to broadcast granular status updates and lifecycle events to the application layer.
- Client-Side File Validations - Executes custom filter functions on file objects before they are committed to the upload queue to enforce data constraints.
