Task manager system using Clean Architecture, DDD and CQRS.

Environment setup

Install Docker
Clone the project: git clone https://github.com/k0t9i/TaskManager-php-ddd.git
Run docker containers: docker-compose -f ./backend/symfony/docker-compose.yml up -d --build
Setup application: make setup. This step installs the composer dependency, generates JWT keys, runs migrations, warms up the cache and reloads the supervisor.

Performing checks

make test - phpunit tests
make code-style - php-cs-fixer checks
make static-analysis - psalm checks
make check-all - all of the above

Api

Swagger api is available on http://127.0.0.1:8081/api/doc

Database

All data is stored on one server in one database, you can see the database structure via adminer http://127.0.0.1:9080/.

Frontend example

Simple vue3 application is available on http://127.0.0.1:7080/

Code structure

 Projects  // Code related to a specific bounded context
  Application // Application layer depends only on Domain layer
   Command
   Handler // Command handlers
   Service // Application services
   Subscriber // Domain event subscribers
  Domain // Domain logic layer does not depend on other layers
   Collection
   Entity // Entities and aggregate roots
   Event // Domain events
   Exception // Domain exceptions
   Repository // Repository interfaces
   ValueObject
  Infrastructure // Infrastructure layer depends on Domain and Application layers
      Persistence // Entity mapping in database
      Repository // Repository realizations
      Service
 Shared // Common code for all bounded contexts

Buses

Command and query buses are synchronous, implemented via the symfony messenger.

The application has two event buses: the domain event bus and the integration event bus.

The domain event bus is synchronous, implemented via the symfony messenger and used inside bounded contexts.

The integration event bus is asynchronous, implemented via the symfony messenger and RabbitMQ (http://127.0.0.1:15673/). Events are received from RabbitMQ through the Symfony Messenger, which is launched using the supervisor.
