Here we are! We will implement the code of our project. Our application is composed of three domains:

• Teams: To manage the information of all the teams that participate in the World Cup competition
• Matches: To manage the information of all the Matches during the competition
• Security: To manage the information of the users and permissions

The teams and matches follow the same implementation with a few variants. For that reason, in this section, we will write the code to implement the Team domain and then expose it via our API, and you will be able to implement the code for the Match domains yourself. Of course, the complete source code is available in the https://github.com/Packt-Aurelia-Fullstack-Book/worldcup-app GitHub repository.

So, having said that. Let's start!
