pLayout.js

import BaseLayout from "@/Layouts/BaseLayout.vue"; // Should contain `<slot>`

export const pLayout = (title) => {
    return (h, page) => h(BaseLayout, { title }, () => page);
};

Usage:

import {pLayout} from '@/Utils/pLayoutUtil';
// ...
defineOptions({
    layout: pLayout('Dashboard'),
});

With this, the Inertia/Vue routing will not cause full re-render of the page.
