Project structure

The logic is very basic to understand:

    |_src
        |_ beans  : contain the main class used in all project. Like other typescript project has inside that the constants and the creation logic(because of class-transformer)
        |_ service: contain the main business logic
        |_ common : differently from service, this folder not contain business logic
        |_ handler: contain the main of the function visibile for the user. Is the center of the API 

I decide to use some libraries:

1. class-validator: It's very convenient to test inputs in this declarative way
2. class-transformer: facilitates the reading of transformations
