composer update protonemedia/laravel-spladenpm upgrade @protonemedia/laravel-splade
Make sure to clear Laravel's view cache after upgrading:
php artisan view:clear
Lastly, if you've published the config file or the Blade templates, make sure your customizations are up-to-date with the defaults.
Verify installed packages
You may use the built-in Artisan Command to show the installed versions of the packages:
php artisan splade:show-versions
