TODO

• Unit Tests
• Store user with encrypted password
• Add unique index to user's email column and avoid duplicated records
• Authentication user
• Issue JWT token after authentication
• Extract HTTP handler to handler sub-package
• Extract Business logic (e.g. Create User in DB) to service sub-package
• Update User's name (with JWT token)
• Create order for user (with JWT token)
• Introduce a validation framework into application layer
• Deploy to Heroku
