Laravel 9 with Inertia Vue 3 Implement Flash Message

In this short tutorial we will see how implement session flash message laravel with inertia vue 3. For this section we will use Vue 3 SFCs method <script setup>

CategoryController.php

public function store(Request $request)
{
    $request->validate([
        'name' => 'required|string|max:255',
        'slug' => 'required|string|max:255',
    ]);


    Category::create([
        'name' => $request->name,
        'slug' => \Str::slug($request->slug)
    ]);
    sleep(1);


    return redirect()->route('category.index')->with('message', 'Category Created Successfully');
}


app/Http/Middleware/HandleInertiaRequests.php

<?php

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Inertia\Middleware;
use Tightenco\Ziggy\Ziggy;

class HandleInertiaRequests extends Middleware
{
    /**
     * The root template that is loaded on the first page visit.
     *
     * @var string
     */
    protected $rootView = 'app';

    /**
     * Determine the current asset version.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return string|null
     */
    public function version(Request $request)
    {
        return parent::version($request);
    }

    /**
     * Define the props that are shared by default.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function share(Request $request)
    {
        return array_merge(parent::share($request), [
            'auth' => [
                'user' => $request->user(),
            ],
            'ziggy' => function () {
                return (new Ziggy)->toArray();
            },
            'flash' => [
                'message' => session('message')
            ]
        ]);
    }
}

You need to add flash message in HandleInertiaRequests.php shared data.

'flash' => [
    'message' => fn () => $request->session()->get('message')
],

// Or
'flash' => [
   'message' => session('message')
]


Category/Index.vue

<script setup>

defineProps({
    categories: {
        type: Object,
        default: () => ({}),
    },
});
function destroy(id) {
    if (confirm("Are you sure you want to Delete")) {
        Inertia.delete(route("category.destroy", id));
    }
}

</script>

                </div>
            </div>
        </div>
    </BreezeAuthenticatedLayout>
</template>

You can also add flash message in main components.

<template>
  <main>
    <header></header>
    <content>
      <div v-if="$page.props.flash.message" class="alert">
        {{ $page.props.flash.message }}
      </div>
      <slot />
    </content>
    <footer></footer>
  </main>
</template>
