Upload from Google Drive [Feature]

[akhil-rana]

This works with SlideLoader #40 and Distro #154

Description

• An "upload from google drive" icon is provided during the upload process.
• Google Picker API is used to let user choose a file from their google drive storage.
• The picker api will extract the fileID from the chosen file and it'll be sent to Slideloader where Google Drive API will download the corresponding file directly on server-side saving user's time and data.
• The instructions for the API usage is described in docs/cloudUploadAPIs.md

How Has This Been Tested?

• Browser: Firefox (v83), Chromium (v87)
• OS: Windows 10, Arch KDE (Linux-LTS)

Screen-recording Demo :

NOTE:

• The authentication has to be done twice, once for picker api and another time for drive api. Once they are both done. User will not be prompted again for the same.
• The app is shown as unverified because it's in testing phase. User can submit their app to google for verification and that message won't be shown anymore.
