Uppy
Uppy is (going to be) a #JavaScript file uploader that fetches files from Dropbox, Instagram, local disk, remote URLs, and other exciting locations. It has a plugin-based architecture, first-class support for resumable #uploads according to the open standard: tus, and custom encoding backends, making it extensible and robust. Uppy is in the early stages of development and should not be used for anything serious yet.

ping @kent1 pour plus tard ;)
