Get data from server only on first page load

[Aniket-IN]

Hi guys,
I'm very new to Inertia,
My Stack: laravel, Inertia, React.

I have got a few data that needs to be included on every page,

I tried using HandleInertiaRequests Middleware
but it fetches the data from the database on every Inertia Request (which I don't want).

What I want is very similar to Inertia::lazy( ... ), but the only difference is I want the data to load on the first page by default.
Then maybe I can store that data to localstorage or something like that.

Hey @Aniket-IN
you can check for Inertia's Header - it will only be there on an Inertia vist. Initial visits do not contain the header. This way you can achieve the desired "load once" behaviour, e.g.

use Illuminate\Http\Request;
use Inertia\Inertia;
use Inertia\Response;

class ExampleController
{
    public function __invoke(Request $request): Response
    {
        return Inertia::render('Example', [
            'onlyOnInitialVisit' => !$request->inertia() ? 'Hello World' : null,
        ]);
    }
}

You are awesome @ajnsn,
This is exactly what I was looking for.

Now on the first load after getting the data from the server, I'm storing it in localStorage and whenever the server sends the data again I'm overwriting the localStorage :)

Thank you so much :)
