Laravel Locking Laravel Package

Product Decisions This Supports

• Data-integrity features on concurrent edits. Any screen where two users can open the same record and both hit "Save" (admin panels, CMS pages, support tickets, CRM contacts, inventory items, price lists, ledger entries) is a lost-update bug waiting to happen. Optimistic locking with a version column is the cheapest correct fix, and this package is a drop-in implementation of that pattern for Eloquent models.
• Build-vs-buy on concurrency control. The real decision this informs is whether to (a) adopt a package, (b) copy the ~100-line trait into your codebase, or (c) move to pessimistic row locks. The package's profile — 3 stars, 0 dependents, last release July 2022 — argues strongly for treating it as a reference implementation rather than a dependency.
• Roadmap sequencing for collaboration and multi-tenant features. If the roadmap includes shared editing, approvals, or any workflow with more than one editor per entity, optimistic locking needs to land before those features, not after. Retrofitting a version column onto live tables and every write path is materially more expensive than including it in the initial schema.
• API contract decisions. Optimistic lock failures must map to a specific client response — HTTP 409 Conflict (or 412 Precondition Failed) with a machine-readable code — and drive UX copy ("Someone else changed this record; reload to see the latest"). Adopting the pattern forces that contract to be defined deliberately rather than discovered in production.
• Scope discipline on locking. The package addresses optimistic concurrency only. It does not replace DB transactions, unique constraints, idempotency keys, or pessimistic SELECT ... FOR UPDATE for high-contention counters. A PM decision to adopt it should explicitly exclude those problems from its remit so nobody assumes concurrency is "solved."
• Not a fit for: single-writer systems, append-only event/log tables, analytics pipelines, or anything where last-write-wins is genuinely acceptable. In those cases the version column is pure overhead and an extra migration per table.

When to Consider This Package

Consider it (or, more precisely, the pattern it implements) when all of the following hold:

• The stack is Laravel/PHP and the affected entities are Eloquent models with a stable primary key.
• Writes are low-to-moderate contention — collisions are rare but costly when they occur. Optimistic locking degrades badly under heavy contention because retries spike; that's when you want pessimistic locks or a queue.
• The team is small enough that a bespoke concurrency layer is not worth building from scratch, but sophisticated enough to read and vendor a small trait.
• You need the behavior quickly for an internal tool, admin backend, or MVP where "someone reloads and retries" is acceptable UX.

Look elsewhere (or build in-house) when:

• Maintenance risk is unacceptable. Last release 2022-07-17, 3 stars, zero dependents, no evident community. There is no signal that this supports Laravel 10/11, PHP 8.2+, or current Eloquent internals. A PM should assume it is effectively unmaintained and price in the cost of forking.
• The concurrency semantics are more complex than a single version column — multi-row invariants, cross-aggregate consistency, or optimistic checks that must span a transaction. This package will not model that for you.
• Contention is high. Hot rows, counters, inventory decrements under load: use SELECT ... FOR UPDATE, atomic UPDATE ... WHERE version = ? with retry budgeting, or a serialized write path.
• You already depend on a maintained alternative (webpatser/laravel-uuid-style versioning, Spatie-style audit/versioning packages, or Laravel's own lockForUpdate primitives plus a hand-rolled trait).
• Compliance or supply-chain review is in play. MIT helps, but an unreviewed, unmaintained package touching every write path is a hard sell to security teams. In-house implementation of the same trait is usually the faster approval.

Practical recommendation: do not composer require this as a production dependency. Read it, extract the trait and migration stub, add tests for the conflict path, and own it. That converts a 0.115-score dependency into ~150 lines of first-party code with the same product benefit and none of the abandonment risk.

How to Pitch It (Stakeholders)

To executives (one paragraph): We have a class of bugs where two people edit the same record at the same time and one person's work silently disappears — it shows up as data corruption, support tickets, and occasionally financial or inventory discrepancies. The standard fix is optimistic locking: every record carries a version number, and a save only succeeds if nobody else changed it in the meantime; otherwise the user is told to reload. This package implements that pattern for our Laravel stack under an MIT license. It is small and unmaintained, so my recommendation is to adopt the pattern, not the dependency — roughly one sprint-day of engineering to implement first-party, with lasting protection on our highest-value tables. It is cheap, well-understood, and eliminates a whole category of incidents.

To engineering: The package is a version-column optimistic lock for Eloquent — WHERE id = ? AND version = ? on update, throw/increment on mismatch. Do not take it as a dependency: last release July 2022, no dependents, no evidence of Laravel 10/11 support, and it sits on the hot path of every write. Use it as a spec. We implement a HasOptimisticLock trait ourselves, add version unsigned integers with sensible defaults to the tables that need it, define the 409 Conflict API contract and the front-end "reload" flow, and write tests that simulate two concurrent writers. Also be explicit about what this is not: it does not replace transactions, unique constraints, idempotency keys, or row-level locks for high-contention writes. Budget the work as a schema decision plus a trait plus a UX contract — not as an integration.
