Gymnastic Center Backend

This is a project for the Software Development subject at the Andrés Bello Catholic University.

In this repository you can find a fitness life course application built with NestJS and other technologies.

Architechture

Different software development practices were applied in our application:

• Hexagonal Architechture: Through this architecture we can decouple the business logic from its implementation details.

• Aspect Priented Programming (AOP): Through the different aspects implemented we can cover the orthogonal functionalities or cruss-cutting concerns presents in the application.

• Domain Driven Design (DDD): This approach allows us to model the logic of our application as closely as possible to the reality of the problem domain.

• Command Query Responsability Segregation (CQRS): This pattern allows us to separate read operations (Queries) from write operations (Commands). This is in order to maximize performance, scalability and security in our application.

• Event Sourcing: This pattern allows us to store all the events that occur in our application in order to be able to reconstruct the state of the application through their reproduction.

Tools

• NestJs: Used as backend framework
• MongoDB: Used for the implementation of the different read models and the event store.
• Firebase: Used for handling notifications within the application..
• RabbitMQ: Used to implement a message queue in charge of synchronizing the different read models with the event store.
• Algolia: Used as a search engine and an IA tool for the recomendations.
• Docker: Used to generate the image and containers needed to run the application.
• Cucumber: Used to make the unit tests in the application.
