Collection Laravel Package

Product Decisions This Supports

• Build vs. buy for an in-memory query layer. The real decision isn't "should we adopt this package" — it's "do we want a reusable, framework-agnostic collection/selector primitive at all, or is Illuminate\Support\Collection plus a few private helpers good enough?" The package is small enough to be a reference implementation even if we never install it.
• Architecture: framework-agnostic domain layer. If a roadmap item is "decouple domain logic from Laravel so it can move to workers, CLI tools, or another runtime," a plain-PHP collection type with its own selector is a concrete enabler. This package is a candidate shape for that boundary.
• Feature: user-defined filtering and saved views. A selector that turns a structured query (filters, sorts, projections) into predicates on an in-memory set is exactly the mechanism behind "build your own report," "save this filter," or admin-side ad-hoc querying without new endpoints per filter combination.
• Use cases worth prototyping: report/export generation over modest result sets, ETL and backfill scripts, config- or YAML-driven filter rules, test fixtures and seeders, and internal admin tooling where a small DSL beats a growing pile of if statements.
• Sequencing signal. 0 stars / 0 dependents / opportunity score ~25 is a low-signal package. It should not appear on a roadmap as a dependency; at most it appears as a one-day spike with a written exit criterion. Treat the decision as "borrow the idea," not "take the dependency."

When to Consider This Package

Adopt only if all of these hold:

• The code in question is outside or at the edge of Laravel (a library, a shared domain package, a standalone CLI/worker) where importing Illuminate\Support\Collection would be an unwanted coupling.
• Datasets are small and bounded — collections are eager and materialized; this is not a streaming or large-table tool. Verify memory behavior against your real payload sizes before committing.
• You specifically need the selector/query-DSL layer, not just map/filter/groupBy. The base collection value alone is trivially reproducible in an afternoon.
• Someone owns the vendor/fork risk: license, PHP version support, security review, and a plan to fork or reimplement if the upstream project stalls. A repo on an unfamiliar host with no dependents gets extra scrutiny on provenance and supply chain.
• You've confirmed interop cost at the boundaries — converting between this type and Laravel collections at controller/job edges is real glue code and a recurring source of bugs.

Look elsewhere (or build in-house) when:

• You're staying inside Laravel. Illuminate\Support\Collection / LazyCollection already covers most of this and is maintained, documented, and known to every hire.
• You need performance at scale — prefer generators, LazyCollection, or pushing the query down to the database. In-memory selection is a convenience, not a scaling strategy.
• The system is long-lived or regulated: you need a maintainer with a track record, a release cadence, and a security response path.
• The selector semantics would become a public contract (customer-facing query API). Then you want to own the grammar, versioning, and error messages.

Gating step: a 1–2 day timeboxed spike against a real use case, with explicit pass/fail on (a) does the selector cover our filter shapes, (b) what does the boundary glue cost, (c) can we fork it in a day if needed. If any answer is uncomfortable, reimplement the ~200 lines internally.

How to Pitch It (Stakeholders)

To executives: This is a small, unproven open-source library that offers PHP collection classes plus a query selector for filtering in-memory data. It is not a recommended dependency today — zero adoption signals and an unfamiliar hosting origin mean we'd be taking on maintenance and supply-chain risk for something we could write ourselves in a day or two. The reason to look at it is narrower and more useful: it's a cheap reference design for two things on our roadmap — keeping domain logic framework-agnostic, and giving users self-serve filtering/reporting without a new endpoint per filter. Recommendation: fund a short, timeboxed evaluation, not adoption. Cost is low; the downside of skipping it is that we keep hand-rolling filter logic in several places.

To engineering: Treat small/collection as prior art. It bundles a collection type with a selector that maps a structured query onto predicates — interesting only if we want that outside Laravel's ecosystem. Concerns to validate: eager evaluation and memory profile, PHP version and framework compatibility, license and provenance, and the conversion tax at every boundary with Illuminate\Support\Collection. Default position is to stay on Laravel's collections; the exception is a genuinely framework-agnostic domain package, and even then we should compare "fork this" against "write a minimal internal version with only the operators we actually need." Success criteria for the spike: a working filter path for one real feature, a measured interop cost, and a written fork/exit plan — otherwise we close it out and move on.
