Dockerized skeleton for prooph software Event Machine

event-machine-skeleton's Issues

Class 'AMQPConnection' not found

Hi,

thanks for this wonderfull guide. I head up with this exception while following it.

I did check image used in docker-compose prooph/php:7.2-fpm and it seems that it should be installed, still when i go inside the container and try to check the extension with php -i | grep amqp i get nothing.

Any idea on what is happening would be appreciated?

thanks in advance for your time,
David

Upgrade to Strategility 3.0

Depends on proophsoftware/event-machine#73

event_machine_projection keeps failing: call to a member function run() on null

@codeliner was trying to create prototype suggested here: proophsoftware/es-emergency-call#8

But I'm having issues running the docker image; on particular, the event_machine_projection service keeps failing to start. The logs show the following:

event_machine_projection_1  | Fatal error: Uncaught Error: Call to a member function run() on null in /app/vendor/proophsoftware/event-machine/src/Projecting/ProjectionRunner.php:93
event_machine_projection_1  | Stack trace:

event_machine_projection_1  | #2 {main}
event_machine_projection_1  |   thrown in /app/vendor/proophsoftware/event-machine/src/Projecting/ProjectionRunner.php on line 93

I've checked the code, and seems like EventMachine.php is trying to create a projection runner, but the projection manager in the service container is null.

$this->container->get(self::SERVICE_ID_PROJECTION_MANAGER)

Any ideas why this could be happening? Have you heard this issue before?

Thanks

Update Skeleton

• Use PostgreSQL for write and read model
• Use ReflectionBasedContainer shipped with event machine
• Use Event Machine watch feature for aggregate projection, depends on: proophsoftware/event-machine#22

Why GraphQL was replaced with Swagger UI?

(from pure curiosity)

Default projection of aggregate state

Provide a default projection that is triggered each time an event occurs.
The projection takes _aggregate_type and _aggregate_id from event metadata and uses the new EventMachine::loadAggregateState method to get current state of related aggregate.
State is json_encoded (add hint in README that state should be json_encodeable) by the projection.
Aggregate type is used for mongo collection name (filter not allowed chars) and aggregateId is of course used as document id. The projection can simply perform an upsert.

Hot reload of projections

Find a way to restart projection containers (or php process insight container) on code changes, so that latest changes are also available within the projections.
