Vue components in Inertia with Laravel seems to load twice - laravel

Question

With a newly created Laravel with Inertia and Vue project, I have an error that it runs code inside my vue components twice.
For a simple test demo, I have a Test.vue, with this code
<template>
<div>
TEST
</div>
</template>
<script>
export default {
name: "Test",
mounted() {
console.log('test')
}
}
</script>
<style scoped>
</style>
Route in web.php:
Route::get('/test', array(App\Http\Controllers\DashboardController::class, 'test'));
In controller:
public function test(): Response
{
return Inertia::render('Test');
}
When I go to the route /test, it echoes out 'test' twice on mounted in my console. In more advanced components which calls APIs and such, also calls them twice.
I suspect maybe my project is set up wrongly, in app.blade.php or app.js but cannot figure it out.
I followed the guides on https://inertiajs.com/server-side-setup and https://inertiajs.com/client-side-setup to set this up.
My source code is here: https://github.com/ekstremedia/laravel-inertia
Edit: It seems to only echo out twice in the first component I load. If I in that component link to another component, and go there, it doesn't load that twice.

I found that this is solved by modifying your app.js file in your resources directory thus:
import Vue from 'vue'
import { App as InertiaApp, plugin as InertiaPlugin } from '#inertiajs/inertia-vue'
Vue.use(InertiaPlugin)
new Vue({
render: (h) =>
h(InertiaApp, {
props: {
initialPage: JSON.parse(app.dataset.page),
resolveComponent: (name) => require(`./Pages/${name}`).default,
},
}),
}).$mount(app);
Your problem seems to have been in how you initialized your inertia app.
