Download the PHP package okaufmann/laravel-horizon-doctor without Composer

Laravel Horizon Doctor

Checks your Horizon config against the Laravel queue config to ensure everything is configured as expected. Optionally scans queued job/listener/mail classes for common footguns and cross-checks their queues against Horizon.

Installation

Requirements

• PHP 8.4+
• Laravel 12 or 13 (illuminate/support is pulled in by your app)
• Laravel Horizon (laravel/horizon)

Install

Require the package with Composer:

The service provider and LaravelHorizonDoctor facade are auto-discovered; you do not need to register them manually.

Publish configuration (optional)

You do not have to publish anything; the package merges its defaults. When you want to change options, run:

That adds config/horizon-doctor.php to your app.

Usage

Errors block the exit code by default. Some warnings (for example Horizon supervises a queue that is not listed under the same connection in config/queue.php) print as warnings only. Use php artisan horizon:doctor --strict-warnings or strict_warnings in config/horizon-doctor.php to fail on those as well. The GitHub Action exposes the same behavior via the strict-warnings input.

Each Horizon environment prints a Redis queue overview table (queue name × Laravel queue connection × whether the name is listed in config/queue.php for that connection × which supervisors run it × status). Use --no-overview or show_overview => false in config/horizon-doctor.php to hide it (for example in compact CI logs). Run with -v (or verbose in config) for a short glossary: queue connection vs Redis client vs Horizon supervisor connection.

For a compact reference when writing queueable jobs and listeners, see docs/jobs-horizon-cheatsheet.md.

Queued class scan (optional)

Static analysis of PHP under configurable directories (default: app/Jobs, app/Listeners, app/Mail). Disabled by default so config-only runs stay quick and do not depend on your sources being present or parseable.

• Turn on: php artisan horizon:doctor --scan-jobs, or scan_queued_classes => true in published config/horizon-doctor.php.
• Skip once: --no-scan-jobs overrides config.
• Paths / ignores: queued_class_paths (relative to the app base path), queued_class_exclude_patterns (regexes for Symfony Finder notPath).

Checks performed when scanning:

• Job timeout vs Redis retry_after for the effective Redis connection (literal $connection on the class when present, otherwise queue.default) — strict_job_timeouts chooses error vs warning when the timeout is not safely below retry_after.
• Queued listeners — warns if onQueue() is only used from __construct(); prefer #[Queue], public $queue, or the queue at dispatch time.
• Horizon vs declared queue — after a scan, each environment section can warn if a class targets a Redis queue/connection that no supervisor handles there.

The published composite action can enable scanning with the scan-queued-classes and strict-job-timeouts inputs (see action/README.md); configure paths and exclude patterns in published config/horizon-doctor.php, or run php artisan horizon:doctor --scan-jobs in a custom step.

GitHub Action

Run the same checks in CI with the composite action published from this repository:

Pin a semver tag (for example v1.0.0) instead of @v1 if you want fully reproducible builds. Full inputs, outputs, prerequisite behavior, and Marketplace notes are documented in action/README.md.
