Connecting the new "Data" page to workbench via one-click register-approve-add-start process:

• The "Data" page contains a link to launch the NBI jupyter notebook on workbench
  • https://www.wb.nds.org/start?app=jupyternbi
• When the user clicks on the link:
  • If they are not registered
    • They are prompted to register with email verification and optional approval process
    • Once approved, service is started and approval email sent with link to started service and workbench itself
  • If they are registered/approved but not authenticated
    • They are prompted to authenticate.
    • Once authenticated, service is started and user it directed to running service
  • If they are registered and authenticated
    • If the service isn't running, it is added and started
    • If the service is already running, they get a link to the running service (a new one isn't added via this route)

What needs to be done:

• Endpoint that supports "add and start" capability
• Update registration/authentication endpoints to support "add and start" capability
  • Store requested URL until approval is complete?
• Update UI to support specific endpoint (not landing page) – for example /register?rd=<requested action>

Thoughts:

• One click via API or UI?
• Current GET /start/:sid endpoint requires existing added stack
  • Could modify to be GET  /start?service=<service ID>
• If not authenticated, store request (cookie or redirect URL)
  • Redirect to Register/sign-in page
• If register, need to pass requested URL to registration process (user could close browser/remove cookie, etc)
• If sign-in, need to pass to authenticate method?
  • Authenticate an start or return existing?
