FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package laravel-kafka

LaravelKafka

LaravelKafka is a simple yet powerful library for producing messages to Apache Kafka from your Laravel applications. It builds upon php-rdkafka and adheres to Laravel conventions, including Service Providers, Facades, Queueable Jobs, Artisan commands, dependency injection, and configuration.

🔧 Maintained by OpenNebel

🧩 Features

✅ Synchronous Kafka message sending
🔁 Asynchronous support via Laravel's queue system
🧱 Modular structure (producers, config, jobs, DLQ)
🧠 Support for headers, keys, partitions, msgflags
🛠 Error handling (Dead Letter Queue with full Kafka options)
🧪 Integrated Artisan commands (status, retry-failed)
📦 Compatible with Laravel Horizon, Telescope, Docker, CI/CD

🚀 Installation

1. Install the PHP Kafka extension

📌 Ensure php.ini loads the extension: extension=rdkafka

2. Install the library

⚙️ Configuration

Method 1 – Full Publication (config + migration)

Method 2 – Separate Publication

`.env` File

✉️ Sending Messages

🔹 Synchronous Sending

🔸 Asynchronous Sending (Laravel Queue)

🧩 Usage with Dependency Injection

💥 Error Handling (DLQ)

If flush() fails or the broker is unreachable, the message is:

recorded in the kafka_failed_messages table
all Kafka options are stored as JSON
accessible via Artisan command
manually re-attemptable

Migration:

Retry Failed Messages:

🛠 Artisan Commands

Command	Description
`kafka:status`	Checks Kafka broker connectivity and lists metadata
