Tree Laravel Package

Product Decisions This Supports

• Feature scoping for hierarchy-heavy workflows. Use this package when a feature needs to model, traverse, and reason about parent/child relationships in memory: category and navigation menus, org charts, permission/resource hierarchies, comment threads, decision/workflow trees, dependency or bill-of-materials structures, and breadcrumb generation.
• Build vs. buy. The package replaces a small but error-prone custom layer of recursive array walking, ancestor lookup, depth/height calculation, and traversal ordering. At MIT license and a small API surface, the “buy” cost is near zero, and the “build” alternative is only justified if requirements are highly specialized.
• Roadmap input for hierarchy features. Its visitors (pre-order, post-order, yield/leaves) and node metrics (size, depth, height, root, ancestors, neighbors) map directly to user-facing capabilities such as subtree export, ordered rendering, “show only leaf categories,” dependency resolution, and scoped permission checks.
• Architecture and dependency decisions. Because it is an in-memory data structure rather than a persistence layer, it supports decisions about where hierarchy logic lives: domain/service layer versus database schema. That distinction matters for Laravel applications that already use Eloquent relationships, nested sets, or adjacency lists.
• Risk and maintenance planning. With 574 stars, zero dependents in the observed data, and a 0.x version line, it is a low-cost, low-blast-radius dependency. The PM decision is less “is this strategic?” and more “does the team want to own a small tree utility or delegate it?”

When to Consider This Package

Consider adoption when:

• The application needs in-memory tree construction and traversal rather than database-backed hierarchy querying.
• The domain naturally forms a strict tree (each node has one parent), not a graph, DAG, or many-to-many hierarchy.
• The team wants fluent tree building for fixtures, seed data, configuration-driven menus, or generated organizational structures.
• Features need ancestor/descendant traversal, leaf detection, depth/height, subtree size, or ordered visitors without writing recursive utilities.
• The stack is PHP 8.x/Laravel and the MIT license is acceptable.
• The dependency can be wrapped behind an internal interface, keeping the option to swap implementations later.

Look elsewhere when:

• Hierarchy must be persisted and queried efficiently in a relational database. Use a nested-set or adjacency-list package (for example, Laravel-oriented nested-set/adjacency-list solutions) or recursive CTEs instead.
• Requirements include graphs, multiple parents, cross-links, or DAG semantics. This package models a strict tree.
• The team needs a stable 1.x API contract. The package is still on a 0.x line, so minor releases may introduce breaking changes; pin versions and isolate usage.
• Ecosystem validation is a hard procurement criterion. Zero observed dependents and a narrow feature set mean limited peer evidence.
• Performance requirements involve very large trees or high-frequency mutations; an in-memory PHP object graph may not be the right fit without benchmarking.
• The product needs authorization-aware, database-integrated hierarchy behavior out of the box. This package provides structure and traversal, not persistence, caching, or Laravel integration.

How to Pitch It (Stakeholders)

For executives: This is a small, MIT-licensed PHP utility that gives our teams a reliable way to represent and traverse hierarchical data — menus, categories, org structures, permission trees — without building bespoke recursive code. It is cheap to adopt, easy to remove, and does not add a platform or vendor commitment. The main caveat is that it is an in-memory structure, not a database hierarchy solution, and it is still pre-1.0, so we should pin the version and keep it behind our own interface.

For engineering: The package provides a NodeInterface/Node implementation with parent, child, ancestor, neighbor, depth, height, size, root, and leaf operations, plus a fluent NodeBuilder and pre-order/post-order/yield visitors. It supports PHP 8.4, is MIT-licensed, and has CI, coverage, changelog, and release signals. Adopt it for in-memory tree composition and traversal; do not use it as a replacement for Eloquent-backed nested sets or adjacency lists. Wrap it in a small internal adapter so a future swap is a contained change, and pin the 0.x version to avoid surprise breaks.

Recommendation: Approve for narrow, in-memory hierarchy use cases where the alternative is custom recursive code. Do not standardize on it as the organization’s hierarchy persistence layer.
