Order Checkout Bundle Laravel Package

Getting Started

tourze/order-checkout-bundle is at 0.0.1 — treat it as pre-alpha. There is no tagged documentation and the changelog is empty, so the source tree is your specification.

1. Install with an exact pin so a 0.0.2 patch cannot silently change behavior:

   composer require tourze/order-checkout-bundle:0.0.1
   

2. Read composer.json first. Check the type field (symfony-bundle vs library) and the require block — this determines whether you get auto-discovery or must wire everything by hand. Also note the minimum PHP version and whether it pulls in Doctrine, Symfony Workflow, or a tourze * support package.
3. Read src/ next, in this order: the domain model (Order / OrderItem / Checkout equivalents), any state or status enum, the service/repository interfaces, then the DI configuration (Resources/config/, config/, or DependencyInjection/).
4. First use case: construct an order, attach line items, and drive it through a checkout transition. Everything else in the package exists to support that path.

If there is no Illuminate\Support\ServiceProvider in the tree, this is a Symfony bundle consumed from Laravel — budget time for a manual adapter before you write any feature code.

Implementation Patterns

Bind the abstractions, don't extend the concretes. These bundles typically ship interfaces (OrderInterface, CheckoutServiceInterface) plus one default implementation. Register a Laravel service provider that maps the interfaces to the shipped implementations, then decorate where you need custom logic. This keeps the vendor namespace out of your application code and makes the package swappable if 0.0.x stalls.

Model the checkout as an explicit state machine. Even if the package does not ship one, the order lifecycle (cart → pending → paid → fulfilled → cancelled) is the part you will actually maintain. Keep transitions in your own service that calls into the package's operations, rather than scattering status writes across controllers. When the package's API shifts in a later 0.0.x release, only that one seam needs updating.

Repository indirection over Eloquent coupling. If the package expects a Doctrine-style repository interface, implement it against Eloquent and keep the mapping in one class. Your migrations, casts, and relationships stay native Laravel; the package only ever sees your interface implementation.

Listen to transitions, not to internals. If order events are dispatched, hook them with Laravel listeners for side effects (mail, inventory, webhooks). Do not call into private or @internal-marked methods to trigger side effects — those are the first thing to move in a patch release.

Test against in-memory implementations. Write a fake repository and fake payment/checkout gateway for your test suite. With no fixtures shipped and unstable contracts, your test doubles are the only stable interface you control.

Isolate behind a facade or thin app-level service. Wrap the package in App\Checkout\CheckoutManager with the handful of methods your app actually calls. Controllers and jobs depend on that wrapper, never on Tourze\... classes directly — this is the highest-value pattern for a 0.0.1 dependency.

Gotchas and Tips

• 0.0.x carries no backwards-compatibility promise. Under semver, anything below 1.0.0 may break in a patch. Pin exactly, commit the lockfile, and re-run your checkout test suite before bumping.
• "Bundle" almost certainly means Symfony Bundle. Symfony bundles register via DependencyInjection\*Extension and *Bundle classes, not Laravel's register()/boot(). Laravel package auto-discovery will not find it. You will need your own provider; check composer.json for a extra.laravel.providers key to confirm.
• Empty changelog. With no release notes, diff the tag against main before trusting it. https://github.com/tourze/order-checkout-bundle/commits/0.0.1 at least tells you what landed in the tag; the initial commit is usually the whole package, so read it as documentation.
• Config keys may not be publishable. Look for a Configuration class or a config tree. Symfony config trees do not translate to config/ files — you may have to pass an array into the extension's load() yourself, or construct services manually.
• Transitive tourze/* dependencies. These vendors ship many tiny interdependent packages; version constraints between them are frequently loose (^0.0, dev-main). If you see a dev-main requirement, expect to need a minimum-stability tweak and a prefer-stable guard, and audit what it drags in.
• Money handling is the classic trap. Verify the currency representation (integer minor units vs float vs a money value object) before you persist a single order. If it is float, wrap conversion at your boundary immediately.
• Debugging: php artisan tinker won't help if the container bindings are missing — first confirm app()->bound(OrderInterface::class). For DI-config issues, dump the resolved service with dd(app(OrderInterface::class)); for container-compile errors under Symfony-style definitions, the failing service ID in the exception is your real starting point.
• Extension points to prefer, in order: implement the shipped interfaces → decorate a service → listen to dispatched events. Forking or editing vendor/ is a dead end here, because a 0.0.2 will overwrite you.
• Budget for replacement. At 0.0.1 with no docs and no changelog, assume you may outgrow or abandon this package. The wrapper-service pattern above turns that from a rewrite into a swap.
