Create Welcome.vue

<template>
    Hello World
</template>

<script>
export default {};
</script>

To make shared component

<template>
    <h1>Home</h1>
    <Nav />
    
</template>

<script>
import Nav from '../Shared/Nav.vue';
export default {
    components: { Nav }
};
</script>
Home.vue
<template>
    <nav>
        <ul>
            <li><Link href="/">Home</Link></li>
            <li><Link href="/users">Users</Link></li>
            <li><Link href="/settings">Settings</Link></li>
        </ul>
    </nav>
</template>

<script>
import {Link} from "@inertiajs/vue3";
export default {
    components: {Link}
}
</script>
Shared/Nav.vue
Route::get('/users', function(){
    return Inertia::render('Users', [
        'time' => now()->toTimeString()
    ]);
});

<div style="margin-top: 400px;">
    <p>The current time is {{ time }}</p>
    <Link href="/users" preserve-scroll>Refresh</Link>
</div>

export default {
    props: { time: String }
};
to pass data
<Link href="/users" preserve-scroll>Refresh</Link>
to preserve scroll ( same as e.preventDefault() )

Shared data

public function share(Request $request): array
    {
        return array_merge(parent::share($request), [
            'auth' => [
                'user' => [
                    'username' => 'John Doe'
                ]
            ]
        ]);
    }

<p>Welcome {{ username }}</p>

export default {
		...
    computed: {
        username() {
            return this.$page.props.auth.user.username;
        }
    }
};
middleware HandleInertiaRequests

Global Component

createApp({ render: () => h(App, props) })
      .use(plugin)
      .component('Link', Link)
      .mount(el)

Persistent Layout

export default {
    components : { Layout }
};

// to

export default {
    layout: Layout
};

Default Layout

import Layout from './Shared/Layout.vue'

createInertiaApp({
  resolve: name => {
    const pages = import.meta.glob('./Pages/**/*.vue', { eager: true })
    let page = pages[`./Pages/${name}.vue`]
    page.default.layout = page.default.layout || Layout
    return page
  },
  // ...
})

Dynamic title and meta tags

<template>
    <Head>
        <title>My app - Home</title>
    </Head>
    <h1 class="text-3xl">Home</h1>
</template>
<script setup>
import { Head } from '@inertiajs/vue3';
</script>

OR

<template>
    <Head title="App - Home" />
    <h1 class="text-3xl">Home</h1>
</template>
<script setup>
import { Head } from '@inertiajs/vue3';
</script>

OR

createInertiaApp({
  ...
  title: title => 'My App - ' + title
});

Listing users

Route::get('/users', function(){
    return Inertia::render('Users', [
        'users' => User::all()->map(fn($user) => [
            'name' => $user->name
        ])
    ]);
});

<template>
    <Head title="Users" />
    <h1 class="text-3xl">Users</h1>
    <ul>
        <li v-for="user in users" :key="user.id" v-text="user.name"></li>
    </ul>
</template>

<script setup>
defineProps({ users: Array });
</script>

Pagination

<template>
    <Head title="Users" />
    <h1 class="text-3xl">Users</h1>
    <div class="overflow-hidden rounded-lg border border-gray-200 shadow-md m-5">

Inertia and SPA Technique

Import Aliases

I’m using Vite so this is the code

const path = require('path');

export default defineConfig({
    resolve: {
        alias: {
            '@' : path.resolve('resources/js')
        },
    },
});

npx mix -p // production

mix.extract() // to extract node modules

Api Resource

php artisan make:resource UserResource

return UserResource::collection(User::all());

UserResource::collection(
    User::query()
    ->when(\\Request::input('search'), function($query, $search) {
        $query->where('name', 'like', '%'.$search.'%');
    })
    ->paginate(10)
    ->withQueryString()
),

Wrap In a Module

example Home.vue
move it to js/services/SyntaxHighlighting.js
back to Home.vue
