Messenger
=========

[](#messenger)

Context
-------

[](#context)

This project is an application designed to explore concepts such as Clean Architecture, Test-Driven Development (TDD), Domain-Driven Design (DDD), and Hexagonal Architecture. These approaches aim to produce maintainable, scalable, and testable code.

Technologies
------------

[](#technologies)

- **PHP** : Programming language used for business logic.
- **Composer** : Dependency manager for PHP.
- **PHPUnit** : Tool for unit testing.
- **Docker** : Containerization platform to simplify application execution and isolation.

Key Concepts
------------

[](#key-concepts)

### 1. Clean Architecture

[](#1-clean-architecture)

Clean Architecture is a set of principles designed to organize code in a way that it is independent of frameworks, databases, and user interfaces. It enables:

- Separation of concerns.
- Easier testing.
- More comprehensible and maintainable code.

### 2. Test-Driven Development (TDD)

[](#2-test-driven-development-tdd)

TDD is a development methodology based on writing tests before coding the functionality. The process follows three steps:

- Write a test that fails.
- Write the minimum code necessary to make the test pass.
- Refactor the code while ensuring the tests still pass.

TDD improves code quality and reduces the number of bugs.

### 3. Domain-Driven Design (DDD)

[](#3-domain-driven-design-ddd)

DDD is a software design approach focusing on the business domain. It encourages collaboration between developers and domain experts to:

- Model the domain effectively.
- Use a common language.
- Structure code around business concepts.

### 4. Hexagonal Architecture

[](#4-hexagonal-architecture)

Hexagonal Architecture, or Ports and Adapters Architecture, separates the core application logic from external interactions (UI, databases, APIs, etc.). It allows:

- Easier testing of the application core.
- Replacement of external components without impacting business logic.
- Simplified application evolution.
