jobs-events

When to use

Use when creating jobs, events, listeners, or queued workflows.

Do NOT use when:

• Artisan commands (use artisan-commands skill)
• Scheduling configuration (use laravel-scheduling skill)

Procedure: Create a Job

Step 0: Inspect

1. Check existing jobs — match naming, queue config, retry strategy, failure handling.
2. Determine sync vs. async — only queue work that is slow, retryable, or non-blocking.
3. Check queue driver: .env / config/queue.php (Redis, database, sync).
4. Check Horizon: config/horizon.php for queue names, supervisors, balancing.

Step 1: Create the job class

1. Pass IDs or compact DTOs in constructor — not full models with relations.
2. Set queue via $this->onQueue(Queue::NAME->value).
3. Add tags() for Horizon filtering.
4. Set $maxExceptions, backoff(), $uniqueFor as needed.

Step 2: Implement handle()

1. Keep focused and readable.
2. Delegate complex logic to services/actions.
3. Design for idempotency — retries must not create duplicates.

Step 3: Test

• Bus::fake(), Queue::fake(), Event::fake().
• Test side effects, not just dispatch assertions.

Procedure: Create an Event + Listener

Step 1: Create event

• Past-tense naming: OrderPlaced, ImportCompleted.
• Keep payload focused.
• Laravel 11+: automatic discovery — no manual registration.

Step 2: Create listener

• One responsibility per listener.
• Delegate large logic to services.
• Use ShouldQueue on listeners that do heavy work.

Conventions

→ See guideline php/jobs.md for full conventions (serialization, idempotency, events, dispatching).

Output format

1. Job/Event/Listener class(es) with proper serialization and retry config
2. Event registration in EventServiceProvider if needed

Gotcha

• Without ShouldQueue, jobs run synchronously.
• Queued jobs serialize constructor args — don't pass loaded models.
• Listener exceptions block the event chain — queue heavy listeners.
• Set $tries and $backoff — unlimited retries overwhelm the queue.

Do NOT

• Do NOT serialize Eloquent models with loaded relations into queued jobs.
• Do NOT ignore idempotency — retries must not create duplicates.
• Do NOT hide critical business flows behind deep listener chains.
