Refactoring login code on the server side

We have gathered all the essential ingredients in the previous sections, and as soon as we have the MySQL connection pool created, we can refactor and improve our login code from Chapter 10, Adding a Vuex Store, and Chapter 11, Writing Route Middlewares and Server Middlewares, in the following steps:
