Use Apache Kafka With 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:

1use Junges\Kafka\Facades\Kafka;
2 
3Kafka::publishOn('broker', 'topic')
4    ->withConfigOption('property-name', 'property-value')
5    ->withConfigOptions([
6        'property-name' => 'property-value'
7    ]);

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

 1use Junges\Kafka\Facades\Kafka;
 2 
 3/** @var \Junges\Kafka\Producers\ProducerBuilder $producer */
 4$producer = Kafka::publishOn('broker', 'topic')
 5    ->withConfigOptions(['key' => 'value'])
 6    ->withKafkaKey('your-kafka-key')
 7    ->withKafkaKey('kafka-key')
 8    ->withHeaders(['header-key' => 'header-value']);
 9 
10$producer->send();

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

 1use Junges\Kafka\Facades\Kafka;
 2 
 3$consumer = Kafka::createConsumer('broker')->subscribe('topic');
 4 
 5// Handler via callback:
 6$consumer->withHandler(function(\RdKafka\Message $message) {
 7    // Handle your message here
 8});
 9 
10// Invokable handler:
11class Handler
12{
13    public function __invoke(\RdKafka\Message $message){
14        // Handle your message here
15    }
16}
17 
18$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.
