Laravel Event Visualizer

Laravel package to visualize events with their handlers, including jobs to chain them together.

Installation

You will need PHP 8.1 or higher.

Install the package via composer:

composer require jonaspardon/laravel-event-visualizer --dev

Publish the config file with:

php artisan vendor:publish --tag="event-visualizer-config"

Publish the views with:

php artisan vendor:publish --tag="event-visualizer-views"

Usage

Visit your-app.test/event-visualizer on a non-production environment.

How does it work?

The starting point is your registered app events and their listeners/subscribers as defined in your EventServiceProvider.

For each of those listeners/subscribers, the package will try to find the dispatched events and jobs by parsing the code and traversing through the abstract syntax tree. For every event/job found, the same AST traversal will be done recursively until it reaches the end.
