Ag.Event
========

[](#agevent)

TYPO3 Flow package to support domain events as described in the Domain Events chapter from: [https://vaughnvernon.co/?page\_id=168](https://vaughnvernon.co/?page_id=168)

Why?
----

[](#why)

Because using domain events to communicate information between aggregates, modules and bounded contexts decreases coupling and helps avoiding anemic domain models.

How?
----

[](#how)

See [Ag.Shop](https://github.com/agitso/shop) for an example on how to integrate.

### Event processing

[](#event-processing)

There is a CLI command which can be run via `./flow event:process {eventHandlerName}`, where the `{eventHandlerName}` is defined in `Settings.yaml` for example that way:

```
Ag:
  Event:
    eventHandlers:
      async:
        'Acme\Foo\EventHandler\SomeThingTriggeredEventHandler': TRUE
```

Per convention, the class name's namespace separators are substituted by an undersocre, so the key name in this case would be `Acme_Foo_EventHandler_SomeThingTriggeredEventHandler`.

#### Deamonizing configuration

[](#deamonizing-configuration)

The mentioned CLI command must be kept alive manually because it intrinsically will time out after a specified time range in order to avoid for example the MySQL connection timing out.

In order to achieve that, we have three recommendations here.

##### Using *supervisord*

[](#using-supervisord)

Have a pool with the following configuration:

```
[program:some_thing]
command=/var/www/production/flow event:process Acme_Foo_EventHandler_SomeThingTriggeredEventHandler
environment=FLOW_CONTEXT="Production"
redirect_stderr=true
stdout_logfile=/var/www/production/Data/Logs/Supervisord.log
stderr_logfile=/var/www/production/Data/Logs/Supervisord_error.log
user=theuser
autostart=true
autorestart=true
stopsignal=QUIT
```

##### Using *daemon*

[](#using-daemon)

Start the process with a command similar to this:

```
daemon --name="some_thing" --env="FLOW_CONTEXT=Production" --respawn --stdout="/var/www/production/Data/Logs/DaemonStdOut.log" --stderr="/var/www/production/Data/Logs/DaemonStdErr.log" /var/www/production/flow event:process Acme_Foo_EventHandler_SomeThingTriggeredEventHandler
```

Once started, you can stop this deamon with `daemon --stop --name="some_thing"`.

##### Using *upstart*

[](#using-upstart)

Have an upstart config with especially `respawn` active.
