Laravel Unique Violation Detector Laravel Package

A lightweight Laravel helper for detecting unique constraint violations raised as Illuminate\Database\QueryException. Instead of brittle string matching against driver-specific error messages, it inspects SQLSTATE codes and native error numbers, so your code can reliably distinguish a duplicate-key failure from unrelated database errors—useful for retrying inserts, implementing upserts, or converting duplicates into friendly validation messages.

• Driver-aware detection for MySQL, PostgreSQL, and SQLite unique violations
• Simple trait-based API: pass a QueryException, get a boolean
• Works with Eloquent, the query builder, and raw statements
• Ideal for idempotent writes, retries, and validation error mapping
• Zero configuration, no service provider required
