Using Tus to upload things to Vimeo.
Vimeo.js contains the code for the Vimeo plugin. It handles authentication with Vimeo, creating the video, and then configures the Tus plugin in order to upload.
The client ID in app.js is only allowed to upload to my (@goto-bus-stop) own account though, unfortunately!
When users are signed in, they are redirected to redirect.html, which sends the authentication data to the Vimeo plugin using localStorage events.
Clone, then npm install and run npm run dev to try.
