Countries auth challenge

challenge #1

• add authentication to your own countries react apps
• protect all views, unless a user has logged in they can't view anything, implement what we did in the lecture
• add a register page so users can create accounts
• add a logout button on every view (destroy the localstorage token)

challenge #2 (optional)

• create a "where have you been in the world" app
• users should be able to navigate to a countries page and click on a button to add that country to their list of visited countries
• users should then be able to go to a view at http://localhost:3000/visited-countries that lists all their visited countries
• you'll need to think about nested data structures for this app, a user could have an array of visitedCountry documents
