I write PHP for a living and I only write headless apps with Symfony and Laravel. Blade is an awful template engine with a primitive parser. Twig is tolerable, but for me nothing beats the DX of Inertia with Vue.
You are most likely right. I just fear spreading complexity everywhere. But I also want to take advantage of the vast compute available at clients. So, I am conflicted. Vue is probably a good compromise. Please share your best references on Inertia/Vue.
Only deployments of Inertia I have are internal code I can't readily share, but all it does is replace the very typical pattern of passing json-encoded props to a a blade template that contains a single React/Vue/Svelte component. Now you just return Inertia::render('My/Component', $arr) from your controller or route handler function, and you're good to go.
It also has various magic for router links that do partial refreshes and working with classic (non-json) forms and whatnot. I use none of those, I'm all about json and useFetch() instead, and Inertia's pretty good about getting out of your way when you don't need it. It lets you write as much or as little in SPA style as you want, it's more or less your favorite JS framework as a view layer directly without having to interpose another view as a middleman (the middleman is there, but it's all implicit: you add the @inertia directive inside your <div id="app">, and that's it)
