Antaeus
Antaeus (/ænˈtiːəs/), in Greek mythology, a giant of Libya, the son of the sea god Poseidon and the Earth goddess Gaia. He compelled all strangers who were passing through the country to wrestle with him. Whenever Antaeus touched the Earth (his mother), his strength was renewed, so that even if thrown to the ground, he was invincible. Heracles, in combat with him, discovered the source of his strength and, lifting him up from Earth, crushed him to death.
Welcome to our challenge.
The challenge
As most "Software as a Service" (SaaS) companies, Pleo needs to charge a subscription fee every month. Our database contains a few invoices for the different markets in which we operate. Your task is to build the logic that will pay those invoices on the first of the month. While this may seem simple, there is space for some decisions to be taken and you will be expected to justify them.
Structure
The code given is structured as follows. Feel free however to modify the structure to fit your needs.
├── pleo-antaeus-app
|
| Packages containing the main() application.
| This is where all the dependencies are instantiated.
|
├── pleo-antaeus-core
|
| This is where you will introduce most of your new code.
| Pay attention to the PaymentProvider and BillingService class.
|
├── pleo-antaeus-data
|
| Module interfacing with the database. Contains the models, mappings and access layer.
|
├── pleo-antaeus-models
|
| Definition of models used throughout the application.
|
├── pleo-antaeus-rest
|
| Entry point for REST API. This is where the routes are defined.
