What problem does it solve?

Prevents slow Laravel pages caused by inefficient Eloquent relationship loading and N+1 query patterns, while keeping relationship behavior correct and predictable.

Core Features & Use Cases

• N+1-safe eager loading: Use with() and filtered eager loading to fetch only the needed related records and avoid per-row queries.
• Efficient aggregates and counts: Prefer withCount, withSum, withMax for common summary needs without loading full related collections.
• Safe pivot operations: Update many-to-many links atomically with sync() and add without detaching with syncWithoutDetaching().

Quick Start

Apply constrained eager loading with with() plus withCount() for a paginated endpoint so the ORM returns posts with their author and tags while also including a comments count without triggering N+1 queries.
