File Upload widget with multiple file selection, drag&drop support, progress bar, validation and preview images, audio and video for jQuery. Supports cross-domain, chunked and resumable file uploads. Works with any server-side platform (Google App Engine, PHP, Python, Ruby on Rails, Java, etc.) that supports standard HTML form file uploads.
This module provides a dependency injection container. Modules may define a key and specify a default value (which can be static, cached lazy, or dynamic lazy), but other code can set and reset the value as needed. There is also an event system, for alerting on value changes, both specific to a key and for any key.
