Flowjs – Angular HTML5 Uploader

Flow.js is javascript library which is provides multiple simultaneous, stable and resumable uploads via the HTML5 File API. This library allows automatic resume uploading file when internet connection is lost
either locally or to the server. Additionally its provide a facility to pause, resume and recover uploads without losing any data because flow.js upload file in chunks so only currently chuck is aborted not entire upload.

Flow.js does not depends on third party library, its use HTML 5 API. Flow.js have a ability to break / chunks file in smaller pieces, that’s why currently flow.js support is limited to Firefox 4+, Chrome 11+, Safari 6+ and Internet Explorer 10+.

1. Flow.js is currently available for angular.js (ng-flow)
2. JQuery and node.js backend (link).
