L5 Repository Laravel Package

Product Decisions This Supports

• Architecture: repository layer or not. The central decision this informs is whether to insert an abstraction between application/domain code and Eloquent. Adopting the package is effectively buying the "yes" answer pre-built rather than debating it from scratch.
• Build vs. buy for boilerplate. Teams that say yes to a repository layer almost always end up writing their own BaseRepository, criteria pipeline, caching decorator, and presenters. This package is the "buy" option for that slice of work.
• Feature: consistent list/filter/sort/paginate endpoints. RequestCriteria converts query-string filtering into a convention. That is a product decision about API contract consistency across endpoints and teams, not just a code choice.
• Feature: response shaping. Presenters/transformers let you commit to a stable public API surface independent of schema changes — a product promise to consumers, not an implementation detail.
• Feature: caching as a decorator. A cacheable repository lets you decide "we cache read paths" without rewriting every query site; relevant when scale or latency targets land on the roadmap.
• Roadmap: onboarding and standardization. A shared base repository plus a criteria vocabulary reduces per-team invention — useful when headcount grows faster than architecture review capacity.
• Use cases it fits: internal admin/back-office CRUD, B2B APIs with many near-identical resource endpoints, products with a small data-access team and several API consumers, and codebases that need a mockable persistence seam for tests.
• Risk/exit decision. MIT license and a pattern-based (not framework-forking) design mean exit cost is "refactor our repository classes," not "replatform." That lowers the stakes enough to justify a bounded trial.

When to Consider This Package

Consider it when most of these hold:

• You've already decided (or are strongly leaning) on a repository/abstraction layer. This package does not make that architectural argument for you.
• You have a high count of similar resource endpoints — value scales with number of models, not complexity of any single one.
• You want declarative, reusable query composition (filters, eager loads, scopes) shared across HTTP handlers, jobs, and console commands.
• You want caching and presenter plumbing available without bespoke implementation.
• Your Laravel version is one the package demonstrably supports — verify against your target version before committing, not after.
• Your team is disciplined about keeping business logic out of repositories and letting criteria do the query shaping.

Look elsewhere when:

• The app is small (a handful of models). The repository layer is pure ceremony and will be the first thing deleted.
• Your team's idiom is Eloquent/ActiveRecord and there's no appetite for the abstraction. A package won't resolve a genuine disagreement about architecture.
• You need true domain/persistence separation. This abstracts the query, not the model — repositories still return Eloquent models and collections, which leaks persistence into callers.
• You're moving toward event sourcing, CQRS with separated read models, or DB-level read/write split; criteria-based repositories pull you back toward a single-model shape.
• You require vendor SLAs or demonstrated maintainer responsiveness. The signals here are thin relative to the star count — treat maintenance as something to verify directly (release cadence, issue triage, age of open PRs, bus factor).
• Your platform roadmap includes moving off Laravel or onto a different persistence store.

How to Pitch It (Stakeholders)

For executives: This is a small, reversible cost-avoidance decision, not a platform bet. It substitutes an MIT-licensed library for roughly 2–4 weeks of internal boilerplate — base repository, filtering/sorting conventions, cache decorator, response presenters. Upside is faster delivery of CRUD-heavy surfaces and more uniformity across teams. Downside is bounded because the pattern is generic: exit cost is a refactor of our repository classes, not a migration. The one item to check before approval is maintainer health, since the package's ecosystem signals are weaker than its 4k stars imply.

For engineering: It's a prettus/l5-repository-lineage package — BaseRepository with a criteria pipeline, RequestCriteria for query-string-driven filtering/sorting/eager loading, a cacheable repository decorator, presenters/transformers, and validators. It is a convention layer over Eloquent, not a replacement: you still write model-specific repositories, and the abstraction stops at the query surface. Adopt it if we've already agreed on a repository layer; skip it if we haven't, because it adds indirection without removing a real decision.

Recommended path: trial on one bounded module or service, capture the conventions in a short ADR (what belongs in criteria vs. repository vs. service layer), and set a checkpoint to measure whether it actually reduced code volume and review friction. Do not ratify it org-wide on star count alone.
