Just to offer an alternate opinion for anyone reading -- check out Next.js
Still seems like most people write separate backend and Nest.js is most popular. I am not a biggest fan yet personally.
Laravel Livewire is pretty nice for basic interactivity, which is all many sites need, but React becomes useful as soon as you start needing app-like features. At that point, using Next, which is already plugged in to that ecosystem, is a very nice experience.
Next is great for static sites, too, so nowadays I prefer putting my time into that vs. fragmenting between a more purely server-side framework like Laravel.
Trying to build a "full stack" application with just Next.js is suiciding everyone that comes to the project after you leave.
