how to know when dynamic component has fully loaded

Question

So I'm loading some components dynamically like so:

const Page0 = () => import("@/components/pages/tutorial/Pages/Page0")
const Page1 = () => import("@/components/pages/tutorial/Pages/Page1")

There are 10 more pages like this, which will be called depending on the route params.

I was wondering how I would know if a certain Page was loaded, for the purposes of creating a loading screen, and how I would know when it was being switched.

This is how I'm using it altogether.

<template>
    <div>
        <component :is="current_page"></component>
    </div>
</template>

<script>
    const Page0 = () => import("@/components/pages/tutorial/Pages/Page0/index.vue")
    const Page1 = () => import("@/components/pages/tutorial/Pages/Page1/index.vue")

    export default {
        scrollToTop:
            true,
        components:
            {
                Page0,
                Page1,
            },
        computed:
            {
                current_page ()
                {
                    return "Page" + this.page
                }
            },
        asyncData ({
            route, store, env, params, query, req, res, redirect, error
        })
        {
            return {
                page:
                    params.page
            }
        }
    }
</script>

how to know when dynamic component has fully loaded ?

You can use @hook:mounted for every component dynamic or not to indicate that the component is loaded.

e.g.

<component :is="current_page" @hook:mounted="doSomething"></component>
