This is a Laravel package that integrates the HTMLPurifier library to sanitize and purify HTML input, primarily for XSS protection. It provides a service provider, a facade, a global helper function (`clean()`), and custom Eloquent casts (`CleanHtml`, `CleanHtmlInput`, `CleanHtmlOutput`) for automatic sanitization on model attributes. The core `Purifier` class wraps HTMLPurifier with Laravel's config and filesystem, supporting dynamic configuration, custom HTML definitions, and a non-string bypass option. The package is well-tested and supports Laravel 5.8 through 13.0, with active maintenance and low technical drift.
