Description #
Blade is a clean and powerful templating engine provided with Laravel, the popular PHP web framework. It allows developers to write expressive templates using familiar HTML and embedded directives.
History #
Blade was introduced in 2011 as part of the Laravel framework by Taylor Otwell. It was created to offer a more elegant alternative to raw PHP templates, providing a syntax similar to other popular templating engines but deeply integrated with Laravel’s features and routing system.
