## What it is
A Laravel Eloquent extension that adds recursive relationships for traversing tree and graph data structures using common table expressions (CTEs). It supports one-to-many hierarchies like nested comments and many-to-many graphs, with features like depth, path, cycle detection, and nested results.

## Use cases
- query hierarchical categories with parent-child relationships in Laravel
- traverse nested comments or page hierarchies with Eloquent
- load entire ancestor or descendant trees of a node recursively
- model many-to-many graph relationships with multiple parents
- detect cycles in recursive data structures
- get node depth and path in a hierarchy via CTEs

## When to choose
- you use Laravel Eloquent and need recursive tree or graph queries
- your database supports CTEs (MySQL 8+, PostgreSQL, SQLite, SQL Server)
- you need hierarchical data features like depth, path, or cycle detection out of the box

## When to avoid
- you are not using Laravel or Eloquent ORM
- your database does not support recursive CTEs
- you only need simple one-level parent-child relations without recursion
