Blade Optimizations

BladeServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\View\Compilers\BladeCompiler;

// @see https://laravel-news.com/faster-laravel-optimizations
class BladeServiceProvider extends ServiceProvider
{
    public function register()
    {
        // This is needed as when compiling a string the footers are
        // overwriten and the partials are processed before other templates
        $this->app->singleton('partial.compiler', static fn ($app) => clone $app['blade.compiler']);
    }

    public function boot(BladeCompiler $blade)
    {
        $blade->directive('loop', static fn ($expression) => "<?php foreach ($expression): ?>");
        $blade->directive('endloop', static fn () => '<?php endforeach; ?>');

        $blade->directive('partial', function ($expression) {
            $parts = \explode(',', $expression, 2);
            $parts = \array_map(static fn ($string) => \trim($string), $parts);

            $view = \trim($parts[0], '"\'');
            $variables = $parts[1] ?? '[]';

            $path = $this->app['view']->getFinder()->find($view);

            $compiler = $this->app->make('partial.compiler');
            $compiledPath = $compiler->getCompiledPath($path);

            if (! \is_file($compiledPath)) {
                $previousPath = $compiler->getPath();
                $compiler->compile($path);
                $compiler->setPath($previousPath);
            }

            $contents = $this->app['files']->get($compiledPath);

            return <<<PHP
            <?php call_user_func(function (\$__variables) use (\$__env) { 
                extract(\$__env->getShared(), EXTR_SKIP); 
                if (count(\$__variables)) extract(\$__variables); 
            ?>
            {$contents}
            <?php }, {$variables}) ?>
            PHP;
        });
    }
}

If someone figures out how to avoid having a second Blade compiler instance, please let me know :)

Kind of not possible right now due to this line:

https://github.com/laravel/framework/blob/1066e3955bfd0a7877707786efbf4fda9d450502/src/Illuminate/View/Compilers/BladeCompiler.php#L241

Currently overwrites BladeCompiler@$footer, which breaks if a partial is added inside a template using @extends
