README

This project is a template for a DDD-based Modulith. It uses Symfony and is fully Docker-compatible and can be executed directly with docker compose up. The modules are integrated via IntegrationEvents, which can be found in the extra Integration directory.

A rudimentary library application was implemented to illustrate this. This contains the two BoundedContexts Search and Loan. Books can be added to Search, which then appear as a publication in Loan. Real books can then be purchased and borrowed in Loan.

Some useful commands for controlling the application and development are listed below.

Build images

docker compose build

Start application

docker compose up

Install dependencies

docker compose exec -T php composer install

Execute messages interactive

docker compose exec -iT php bin/console messenger:consume

Stop application

docker compose down

Generate migration

docker compose exec -T php bin/console doctrine:migrations:diff --em=<EntityManager>

The database migrations are carried out automatically when the application is started

Debugging

1. Start application in xDebug-Mode

   XDEBUG_MODE=debug docker compose up -d

2. In the Settings/Preferences dialog, go to PHP | Servers
3. Create a new server:
   • Name: symfony (or whatever you want to use for the variable PHP_IDE_CONFIG)
   • Host: localhost (or the one defined using the SERVER_NAME environment variable)
   • Port: 443
   • Debugger: Xdebug
   • Check Use path mappings
   • Absolute path on the server: /app
4. In PHPStorm, open the Run menu and click on Start Listening for PHP Debug Connections
5. Add the ?XDEBUG_SESSION=PHPSTORM query parameter to the URL of the page you want to debug.

Update the containerization-template

1. Run the script to synchronize your project with the latest version of the skeleton:

   curl -sSL https://raw.githubusercontent.com/mano-lis/template-sync/main/template-sync.sh | sh -s -- https://github.com/dunglas/symfony-docker

2. Resolve conflicts, if any

3. Run git cherry-pick --continue
