I am following the following this guide, that shows how to enable "Route Based Modals" in Inertia.js.
The post is written for Vue2, and I am using Vue3 - and I am having some issues getting it to work.
This is my "Composable" for my "useModal" method:
//Composables/useModal.js
const useModal = {
computed: {
modalComponent() {
return this.$page.props.modal
? () => import(`@/Pages/${this.$page.props.modal}`)
: false
}
}
}
export { useModal }
I then declare it in my app.js file as per below:
//app.js
//...
import {useModal} from "@/Composables/useModal";
createInertiaApp({
title: (title) => `${title}`,
resolve: (name) => require(`./Pages/${name}.vue`),
setup({ el, app, props, plugin }) {
return createApp({ render: () => h(app, props) })
.use(plugin)
.component("Link", Link)
.mixin(useModal)
.mixin({ methods: { route } })
.mount(el);
},
});
In my main layout, called AppLayout I have declared the Component:
<body>
<!-- Main elements are here, removed for clarity -->
<Component
v-bind="$page.props"
v-if="$root.modalComponent"
:is="$root.modalComponent"
/>
</body>
Further, I have declared the modal() method in my AppServiceProvider:
public function boot()
{
ResponseFactory::macro('modal', function ($modal) {
inertia()->share(['modal' => $modal]);
});
}
Now, I am trying to render a Vue component in a modal like so:
//FileController.php
public function show(File $file){
\inertia()->modal('File/Show');
return $this->index($file);
}
When linking to the modal component, the following Warning is issued:
[Vue warn]: Invalid VNode type: undefined (undefined) at <Anonymous key=0 ...
I ended up fixing this by using defineAsyncComponent instead:
//Composables/useModal.js
import {defineAsyncComponent} from "vue";
const useModal = {
computed: {
modalComponent() {
return this.$page.props.modal
? defineAsyncComponent(() => import(`@/Pages/${this.$page.props.modal}`))
: false
}
}
}
export { useModal }
