For those looking for something similar in PHP/Laravel, I strongly recommend checking out Livewire: https://laravel-livewire.com/

I still use React for more complex projects but it’s always a breath of fresh air to be able to write everything in Blade/PHP while keeping the reactive UI elements.

Edit: Although I have not used, I remember seeing this package which lets you render React/Vue components within Livewire when you need it: https://minglejs.unitedbycode.com/ an interesting escape hatch for when you want to pull in existing packages
