A Ja*aScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API Code on Github It’s a Ja*aScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API. The library is designed to introduce fault-tolerance into the upload of large files through HTTP. This is done by splitting each files into small chunks; whenever the upload of a chunk fails, uploading is retried until the procedure completes. This allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows for users to pause, resume and even recover uploads without losing state. Resumable.js does not have any external dependencies other the HTML5 File API. This is relied on for the ability to chunk files into smaller pieces. Currently, this means that support is limited to Firefox 4+ and Chrome 11+. A new Resumable object is created with information of what and where to post: To allow files to be either selected and drag-dropped, you’ll as*ign drop target and a DOM item to be clicked for browsing: r.as*ignBrowse(docu*ent.getElementById('browseBu*ton')); r.as*ignDrop(docu*ent.getElementById('dropTarget')); After this, interaction with Resumable.js is done by listening to events: Most of the magic for Resumable.js happens in the user’s browser, but files still need to be reas*embled from chunks on the server side. This should be a fairly simple task and can be achieved in any web framework or language, which is able to receive file uploads. To handle the state of upload chunks, a number of extra parameters are sent along with all requests: Please note that the size of the data received in the HTTP might be lower than resumableChunkSize of this for the last chunk for a file. You should allow for the same chunk to be uploaded more than once; this isn’t standard behaviour, but on an unstable network environment it could happen, and this case is exactly what Resumable.js is designed for.
