• URO-28: Align TopBar to mockup (presentation and accessibility)
  • Top bar appears as in mockup
  • Top bar has hamburger menu and user account menu
  • Top bar shows KBase logo and environment tag
  • Top bar elements are accessible by voiceover.
• URO-126: Fix login and token issues
  • Update legacy kbase-ui to redirect to a better target after login
  • Investigate a better strategy for dealing with different API auth schemes, I.e. not sending the token/token-cookie if it is not valid/undefined. Right now issues are caused
    • on unauthed pages
    • if a token expires while a user is on the page
  • Show logged out state properly in the topbar
  • Add auth check to collections and any other pages missing it
• URO-127: Logout support
  • Enable logging out without waiting for the heat death of the universe 🌌 .
• URO-142: Create canonical build configuration JSON file.
  • Implement in such a way that discourages the use of other build configuration.
  • File may be imported and used at build time to control how the app behaves.
  • Answer the following questions:
    • How does the app import the build configuration at build time? (load into environment variables in build_deploy.sh.)
    • How may the app access the build configuration at runtime? (Environment variables.)
    • How does the app get the URL of the auth API and other services? (Environment variables.)
