Workflow

Publishing

<?php
$publisher = $container->get(\LeNats\Subscription\Publisher::class);

$event = new \LeNats\Events\CloudEvent();
$event->setType('some.event.type.created'); // This event wil be published to some.event.type queue
// $event->setId('unique-id'); Id will gets from data['id'] field, if it exists 
$data = [
    'id' => 'unique-id',
    'value' => 'Some event value'
];
$event->setData($data);

$publisher->publish($event);

Subscribing

bin/console nats:subscribe some.event.type -t 10
