Inertia Share with a condition to check for inertia load or regular site load

share.php

// Give me a better way of describing the two different loads. full request vs inertia request? idk

// Here is my original share in a service provider

public function boot(SidebarService $sidebar): void
{
    // Share sidebar items with Inertia for global access
    Inertia::share('sidebarItems', $sidebar->getItems());
}


    
// Updated fix for lazy loading

public function boot(SidebarService $sidebar): void
{
    // Share sidebar items with Inertia for global access
    Inertia::share('sidebarItems', function () use ($sidebar) {
        if (request()->header('X-Inertia')) {
            return null; // Skip on navigation
        }
        return Cache::remember('sidebar_items', 3600, fn () => $sidebar->getItems());
    });
}
