Background Tasks Symfony Laravel Package

Getting Started

This is a Symfony bundle, not a Laravel package, so a Laravel developer's first move is to confirm the fit before installing anything. It belongs in a Symfony application (or a Symfony bundle embedded in a larger PHP service) that wants fire-and-forget background work without standing up a queue worker like Horizon or a broker like Redis/SQS.

First steps:

1. Read the bundle's README and the src/ directory of the v0.1.2 tag on GitHub — the release notes are only a changelog link, so the code and tests are your source of truth for what actually changed between v0.1.1 and v0.1.2.
2. Register the bundle in config/bundles.php (Symfony) and check for a DependencyInjection/Configuration.php to see what config keys exist.
3. Find the "run a task in the background" entry point — typically an attribute, a service method, or a messenger-like dispatcher. Start there.
4. First use case: take one slow, non-critical side effect from a request cycle (sending a notification, resizing an image, writing an audit log) and move it into a background task to validate the round-trip.

If you are on Laravel and need background work, the equivalent native tools are queued jobs (ShouldQueue), dispatch(), and php artisan queue:work. Only reach for this bundle if you maintain a Symfony service alongside your Laravel app and want a consistent pattern across both.

Implementation Patterns

• Attribute-driven dispatch — if the bundle exposes a PHP attribute (common for this style of package), apply it to a handler/service method and let the bundle fork or spawn the process. Keep the attribute target a small, serializable payload.
• Service-per-task — wrap each unit of background work in a dedicated class with a single __invoke() or run() method. This mirrors Laravel's job classes and keeps the bundle's surface area small.
• Fire-and-forget at the controller edge — dispatch after the response is prepared, never before a DB transaction commits. If you need "after commit" semantics, defer the dispatch yourself (Symfony kernel.terminate listener, or Laravel's DB::afterCommit).
• Idempotency by contract — because there is no durable queue visible to the caller, treat every task as potentially executed more than once. Pass an idempotency key in the payload and check it in the handler.
• Configuration-as-code — put any concurrency, timeout, or log-level settings in config/packages/*.yaml and commit them; do not rely on defaults across environments.
• Integration tip for mixed stacks — if a Laravel app calls into a Symfony service that uses this bundle, wrap the dispatch behind a thin HTTP endpoint on the Symfony side rather than sharing the bundle directly. Keeps the two applications independently deployable.

Gotchas and Tips

• It is not a Laravel package. There is no service provider, no config/background-tasks.php, and no facade. Do not expect dispatch() or Bus::dispatch() idioms. You are wiring Symfony services by hand.
• Patch release with no notes. v0.1.2 is a 0.1.x patch, and the only public artifact is a compare link. Before upgrading from v0.1.1, diff the tags (git diff v0.1.1..v0.1.2) and check the CHANGELOG.md — pre-1.0 projects can and do ship behavior changes in patch versions.
• Pre-1.0 stability. At v0.1.2 the public API is not frozen. Pin the exact version in composer.json ("vtitar/background-tasks-symfony": "0.1.2") and read the source before relying on any method signature.
• No observability out of the box. Background tasks fail silently by definition. Wrap every handler in a try/catch that logs with a correlation ID, and add a health check that asserts recent task completions.
• Signal/fork behavior differs across PHP SAPIs. Test under both CLI and PHP-FPM; some process-spawning approaches behave differently when the parent is the FPM worker. Verify with a deliberate sleep() in the task.
• Serialization limits. Anything you pass into a background task must survive process boundaries — no closures, no live PDO connections, no Request objects. Use scalars, arrays, or DTOs implementing \Serializable.
• Worker-less design has no retry by default. If the bundle does not ship a retry policy (check the source), implement retries inside the handler with a bounded loop and a dead-letter log. This is the most common production surprise.
• Extension points — look for EventDispatcher integration and a TaskInterface/HandlerInterface. Those are the hooks for decorating behavior (metrics, tracing, retry) without forking the bundle.
• Debugging — set the bundle's logger to debug in config/packages/dev/, tail the Symfony log, and add a dump() inside the dispatch path to confirm the task is actually queued and not executed inline on the request thread.
