Use Apache Kafka With Laravel

Laravel Kafka is a package for using Apache Kafka producers and consumers in your Laravel app with ease. Using the publishOn method, you can fluently configure and publish message payloads:

use Junges\Kafka\Facades\Kafka;

Kafka::publishOn('broker', 'topic')
    ->withConfigOption('property-name', 'property-value')
    ->withConfigOptions([
        'property-name' => 'property-value'
    ]);

Here's an example of how you send a message to Kafka via this package in a Laravel app:

use Junges\Kafka\Facades\Kafka;

/** @var \Junges\Kafka\Producers\ProducerBuilder $producer */
$producer = Kafka::publishOn('broker', 'topic')
    ->withConfigOptions(['key' => 'value'])
    ->withKafkaKey('your-kafka-key')
    ->withKafkaKey('kafka-key')
    ->withHeaders(['header-key' => 'header-value']);

$producer->send();

And here's an example of subscribing to messages via a consumer:

use Junges\Kafka\Facades\Kafka;

$consumer = Kafka::createConsumer('broker')->subscribe('topic');

// Handler via callback:
$consumer->withHandler(function(\RdKafka\Message $message) {
    // Handle your message here
});

// Invokable handler:
class Handler
{
    public function __invoke(\RdKafka\Message $message){
        // Handle your message here
    }
}

$consumer->withHandler(Handler::class)

Other features this package provides as found in the readme:

• Configure max messages to be consumed
• Configure a Dead letter queue - Wikipedia
• Configure middleware
• Kafka::fake() method for faking a Kafka producer in tests
• Method to enable debugging during development
• Configurable message payloads

Under-the-hood, this package requires the rdkafka extension, which provides a production-ready, fast Kafka client for PHP. You can learn more about this package, get full installation instructions, and view the source code on GitHub.
