Mastering Laravel Queues: Basics to Advanced Techniques

Dispatch and delay jobs in Laravel queues, then build an image processing app that handles image uploads in the background, exploring synchronous versus Redis or database drivers and delays.

Learn how to dispatch an image processing job that emails a user a photo attachment using Laravel queues, a Livewire component, a mailable, and a test mailbox.

Add an alert to the component to display a message after a queued job processes, illustrating immediate feedback and future multi-step background jobs for image sizes and email delivery.

Install and configure an image manipulation library compatible with GD or IMG for a Laravel queues workflow, then split image processing into parallel jobs with a final email attachment step.

Process background image manipulation and send email to user within Laravel queues by debugging docker-based jobs, managing file paths, resizing images, handling attachments, and serializing processing into separate jobs.

Split a large image processing job into multiple queue jobs and dispatch image resize tasks alongside email sending. Understand serialization issues and dependency tracking in Laravel queues.

Explore job chaining in Laravel queues to sequence dependent tasks, prevent race conditions across workers, and understand encrypted jobs for compliance using the should be encrypted interface.

Master the bus facade for job chaining by dispatching an array of jobs on the same queue to run in order with parameters like file output path and sizes. Create a dedicated job for sending user email, iterate over sizes with a for each, and explore a closure and failed job handling for robust queues.

Explore how job batching in Laravel allows parallel execution across multiple workers, unlike job chaining which runs tasks sequentially; learn tracking batch progress and handling failures with batch closures.

Learn how to orchestrate Laravel job batching and mixing batches and chains, handle cancellations with middleware, and use life cycle hooks, progress, and pruning for robust queues.

Fix logging for Laravel queue workers by using the correct log file instead of stdout, and configure production workers with supervisor in Docker or Kubernetes.

Learn how to manage failed Laravel queue jobs by retrieving them with artisan, scheduling regular checks via cron, and diagnosing failures to mitigate issues rather than blindly deleting records.

Explore testing queue jobs in Laravel using queue facilities, including faking jobs and tests of a Livewire upload component to verify dispatch of image processor, image resizer, and user emails.

Explore testing queue jobs by focusing on batches, bus, and chains, using assert batched and assert batch count to verify batching while separating queue and bus fakes.

Install and configure Laravel Horizon with Redis, publish the config, set up horizon workers and the scheduler for regular snapshots, and address production requirements like the Redis extension.

Install and configure the Laravel workflow based queue package, publish its config, run migrations, and learn to orchestrate parallel and dependent jobs with chains and batches.

Upgrade to Laravel 11 requires minimal changes; publish the queue configuration with one or two commands and Horizon remains compatible, following the upgrade doc.
