I worked on a different solution.
I forked js-beautify and published a new package to format Blade files as HTML
you can find it from here: https://github.com/ThePlanet-Tech/js-beautify
I still need more contributors & testers to make sure everything is smooth and working fine.
you can install the package by npm install js-beautify-with-blade
then use it html-beautify -r resources/views/**/*.blade.php
you can also configure all the rules you want on .jsbeautifyrc
