tus.io – Resumable file uploads for web and mobile apps by Felix Geisendörfer

3,323 views

Published on

File uploading is an incredibly annoying, yet very important feature to get right for your applications. Unfortunately time is usually short, so most applications handle network errors during file uploads very poorly. For this reason we have started tus.io, which aims to define an open protocol for resumable file uploads along with providing implementations for all plattforms and languages. This session will introduce you to the project, and show you how to add better file uploading to your web and mobile apps.
