Nest Tool Laravel Package

Product Decisions This Supports

• Feature scoping for hierarchical data. Any roadmap item that needs trees — category/taxonomy management, multi-level navigation menus, org and team hierarchies, threaded comments, permission/role trees, product bundles — is the addressable surface. This package is a candidate implementation detail for that class of feature, not a feature in itself.
• Build vs. buy vs. borrow. The package gives engineering a concrete, small worked example of the nested-set model in Eloquent (left/right boundary columns, subtree moves, ancestor/descendant queries). That makes it useful as a reference implementation for estimating in-house effort, which is the decision actually on the table.
• De-risking a spike, not a commitment. If tree support is 1–2 quarters out, a half-day spike against this repo validates query patterns and admin UI ergonomics before the team commits to a library or a custom schema. Cheap learning, zero production exposure.
• Migration planning. If we already have a flat parent_id structure that is straining under recursive queries, this is a readable contrast case for what a nested-set migration would cost in writes and integrity checks.
• Portfolio hygiene / dependency policy. Evaluating it forces an explicit answer to "what is our minimum bar for a third-party dependency?" — which is a reusable decision for every future package review, not just this one.

When to Consider This Package

Consider it only as:

• A learning/reference artifact for engineers designing a tree feature.
• A prototype or internal-tool dependency where a broken hierarchy is an annoyance, not an incident, and there is no external exposure.
• A comparison baseline when benchmarking maintained alternatives during a library selection.

Do not consider it when any of the following are true:

• The feature is customer-facing, write-heavy, or integrity-critical (concurrent subtree moves, reordering under load, audit requirements).
• We need current Laravel/PHP support. Last release was June 2020, which predates Laravel 9/10/11 and modern PHP — expect version-constraint conflicts before you hit any logic.
• We require security review, an SLA, or a named maintainer. 2 stars, 0 dependents, single author, no activity in ~5 years means bus factor of one and no patch path if a vulnerability lands. Our own dependency policy should stop this at the door.
• A compliance or procurement review will ask "who maintains this?" — the honest answer is "nobody."

Look elsewhere for production:

• Maintained nested-set library (e.g. kalnoy/nestedset) — the default answer for this exact data model; check its current Laravel support before adopting.
• Adjacency list + recursive CTE (e.g. staudenmeir/laravel-adjacency-list) if writes outnumber reads and the tree is shallow.
• Closure table if we need arbitrary many-to-many-ish ancestry with heavy read patterns.
• Build in-house — for a tree of 2–3 levels with modest volume, a plain parent_id column plus a scoped recursive query is often a few days of work and beats adding a dependency at all.

Before any adoption, require a 30-minute source audit: test suite existence and coverage, migration/rollback support, PHP and Laravel version constraints in composer.json, and whether the query builder is safe against concurrent writes. Given the signals above, expect this audit to fail — and treat that as a valid, fast outcome.

How to Pitch It (Stakeholders)

Executives: This is a small, unmaintained PHP package for storing hierarchical data — category trees, menus, org structures. It is not a recommendation to add a dependency. With two stars, no downstream users, and no release since mid-2020, adopting it in production would mean owning abandoned code with no security patch path. The value here is informational: it gives the team a cheap reference point for sizing the tree feature already on the roadmap, and it lets us settle the build-vs-buy question with evidence rather than opinion. Ask: half a day of engineering time for a spike; no production commitment.

Engineering: Treat it as a design input, not a library. Read it to see a minimal nested-set implementation in Eloquent, then benchmark against a maintained alternative or a parent_id-plus-recursive-query approach. The spike's deliverable is a one-page recommendation — library, in-house, or defer — with the schema, integrity guarantees, and write-path costs spelled out, and a note on which option survives our next Laravel upgrade.

Bottom line: Low cost to evaluate, high cost to depend on. Use it to make a decision; don't let it become one.
