• DATABASE_URL
  • this specifies the database to use
  • default value: sqlite://test.db (sqlite database in the source code directory)
  • supports mysql, postgresql and sqlite (sqlite in development builds only because it's declared as dev dependency)
  • looks like postgres://user:pass@example.com:5432/dbname
  • no extra setup needed
    • when starting the application, the database tables are created/ migrated
      • this only works for upgrading; if you intend to eventually downgrade, make a backup first (you should make backups in all cases before an upgrade)
• PORT

• MAIL_SENDER
  • sender (for the from-field) for sent mails

  • note: this allows a third party who knows the server url to check if a certain mail address is allowed by trying to sign in with it
