Shoppingcart Laravel Package

Product Decisions This Supports

• Cart mechanics as a commodity build: The package supplies add/update/remove line items, quantities, Eloquent model association, subtotal/total calculation, and stackable conditions (tax, shipping, discounts). That lets a team stand up a credible purchase flow in days for internal tools, order pads, MVPs, pilots, and B2B quote carts where the cart is table stakes rather than the differentiator.
• Build vs. buy: Substitutes roughly 1–2 engineering sprints of undifferentiated cart logic — session or database persistence, condition stacking, total recalculation, model binding — and redirects that budget to checkout conversion, pricing, and fulfillment, which customers actually notice.
• Scope boundary decisions: It sharpens the line between "cart" and "commerce." Checkout, payments, inventory, subscriptions, refunds, and tax compliance are explicitly out of scope and must be separate build/buy calls (e.g., Stripe for payments, TaxJar/Stripe Tax for tax). Making that boundary explicit early prevents scope creep into a library that was never designed for it.
• Roadmap commitment: Adopting it creates an implicit maintenance obligation — every Laravel/PHP upgrade becomes a cart-compatibility check. Budget a small recurring upkeep line (pinning, CI upgrade tests, a named owner) or plan to fork. Release 3.4 (Laravel 12 support) is evidence the upstream is still tracking framework releases, which lowers — but does not eliminate — that carrying cost.
• Reversibility as a decision property: MIT license plus small surface area means the code is ours if the upstream stalls. This is a low-cost, reversible "yes," not a strategic platform bet — the right framing for a decision that shouldn't consume executive bandwidth.

When to Consider This Package

Adopt when:

• The product is already Laravel-based and the cart is a supporting capability, not the product itself.
• You are on Laravel 12 (explicitly supported as of 3.4) or a still-supported earlier major — confirm the version you actually run appears in the compatibility matrix rather than assuming the latest tag covers you.
• Requirements are conventional: single or lightly multi-currency, a handful of condition types (tax, shipping, one or two discount rules), carts tied to session or user, modest order volume.
• The team is small and time-to-market outweighs owning every line of cart code.
• You can accept a session/database cart model without real-time price revalidation on every page view.
• You are willing to pin the version, cover framework upgrades in CI, and fork if maintenance lags.

Look elsewhere when:

• You need a full commerce stack — catalog, checkout, payments, subscriptions, inventory, refunds. Evaluate Lunar PHP, Aimeos, or a hosted platform instead.
• You need complex promotions: stacking conflicts, priority rules, B2B price lists, tiered or tax-inclusive regional pricing. The conditions API is simple by design and will be outgrown.
• You need a cart ledger at high concurrency across nodes; sessions are the wrong store for that.
• You need financial-grade auditability of cart/order history — persist your own immutable snapshots.
• You are not on a supported Laravel/PHP version, or you require a vendor SLA. With ~356 stars and effectively zero recorded dependent packages, the maintainer base is thin — 3.4 confirms the project is alive and current with Laravel 12, but verify the compatibility matrix, read recent commits, and confirm the release actually supports your exact framework and PHP version.
• Security posture is immature: totals held in session or client state are tamper-prone, so server-side recomputation from trusted prices is mandatory, not optional.

Pre-approval gates: confirmed Laravel/PHP compatibility (3.4 covers Laravel 12 — check your specific major and PHP constraint), verified recent commit activity, a named internal owner, and a thin internal adapter so the dependency can be swapped.

How to Pitch It (Stakeholders)

Executives: A free, MIT-licensed Laravel library that gives us a working shopping cart — line items, quantities, totals, tax, shipping and discount lines — in days rather than a sprint or more. It is commodity plumbing, not a differentiator, so buying over building is the right call: it moves engineering capacity to checkout conversion, pricing, and fulfillment, which do drive revenue. The project just shipped Laravel 12 support, so it is actively tracking the framework rather than drifting. The cost is a dependency plus light upkeep, and the code is ours to fork if the project ever stalls, so this is a low-risk, reversible decision rather than a platform commitment. It does not handle payments, checkout, inventory, or tax compliance — those stay as explicit decisions we make separately.

Engineering: Treat it as a cart engine, not a commerce platform. Wrap it behind our own CartService/repository so no controller touches Cart::* directly — that preserves a swap path and gives us one place to enforce invariants. Recompute all prices and totals server-side at checkout from trusted sources; never trust session-stored values. Pin the version, add framework-upgrade coverage to CI, and monitor upstream — 3.4 adds Laravel 12 support, which is a good sign, but it remains a fork of the Cyber-Duck original with a small maintainer base and no recorded dependents on Packagist, so the upgrade check is still on us. Expect roughly 1–2 sprints saved on basic cart behavior, plus 1–2 days for the wrapper, tests, and pricing validation. If the roadmap includes complex promotions, multi-warehouse inventory, or subscription billing, scope those outside this package now rather than bending its conditions API.
