Require login for downloading data

[MillenniumFalconMechanic]

Need

• A configurable "login required for downloading data" option is needed for prompting users to login before initiating a download. Specifically, a login-required popup is displayed on click of download if user is not authenticated and the "login required" flag is set for an app.

• Login is not required to view pages that display download buttons (e.g. on the "Choose Export Method" page, login is only required on click of a download option not to view the actual page).

• User should remain in the same flow as before login. For example:

  1. User navigates to entity download page.
  2. User clicks request curl command.
  3. System displays login modal.
  4. User logs in.
  5. curl command is requested.

• The download actions that require authentication are:

  1. Direct file download (from files tab)
  2. Request curl Command (from cohort Choose Export Method)
  3. Request File Manifest (from cohort Choose Export Method)
  4. Analyze in Terra (from cohort Choose Export Method)
  5. Request curl Command (from cohort Download Selected Data Using "curl")
  6. Prepare Manifest (from cohort Request File Manifest)
  7. Request Link (from cohort Export to Terra)
  8. Metadata download and copy (from entity Metadata tab)
  9. File manifest download and copy (from entity Metadata tab)
  10. Matrices download and copy (from entity Matrices tab)
  11. Request curl Command (from entity Download tab)
  12. Request Link (from entity Export tab)

  Note: this list may require updating once Make the general and dataset-details Export panes consistent is completed.

• No change is required to the regular login use case unless updates to existing implementation are required to facilitate reuse with this ticket's use case.

• See design ticket for rationale and mock for implementation.

Approach

• Document technical design.
  • See intended approach.
