impress-2020/scripts/export-users-to-auth0.js

// This exports users from the MySQL database to Auth0.
//
// If you use the --since flag, we'll only include users whose OpenNeo ID
// records were updated (or created) since then. Otherwise, we'll include all
// users.
//
// This sorta creates a second copy of everyone's account, copied onto Auth0.
// We should be thoughtful about how we do the actual migration process!
//
// For now, we can run this whenever we want to make it _possible_ to log in
// with Auth0, even if things will be potentially out of sync, because traffic
// to Impress 2020 is just testers now anyway!
