Laravel 9 - Livewire SPA CRUD

Published on May 15, 2022

Hello Artisans, today we'll discuss about SPA (single page application) CRUD with Laravel & Livewire. Livewire is a full-stack frontend framework for Laravel that makes building dynamic interfaces simple, without leaving the comfort of Laravel. It is a frontend framework. For more you can check here So, no more talk, let's see how we can easily crate a simple SPA CRUD application using Laravel & Livewire Application.

Note: Tested on Laravel 9.11

  1. Install and configure Livewire
  2. Create and Configure Livewire Component & View
  3. Define Routes
  4. Create and Setup blade File
  5. Output

Install and configure Livewire

To install Livewire, we just need to fire the below command

composer require calebporzio/livewire

That's it, we've successfully install the Livewire.

Create and Configure Livewire Component & View

Fire the below command to create the Livewire Component & view.

php artisan make:livewire user

After running the command, it'll create two file in the following path.

  1. app/Http/Livewire/User.php
  2. resources/views/livewire/user.php

In this step, we'll work with only component file named User.php. Later we'll work with blade file. So, open the User.php and replace with following codes.

app/Http/Livewire/User.php
<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\Models\User as UserModel;

class User extends Component
{
    public $data, $name, $email, $password, $selected_id;
    public $updateMode = false;

    public function render()
    {
        $this->data = UserModel::all();
        return view('livewire.user');
    }
    private function resetInput()
    {
        $this->name = null;
        $this->email = null;
        $this->password = null;
    }
    public function store()
    {
        $this->validate([
            'name' => 'required|min:5',
            'email' => 'required|email:rfc,dns',
            'password' => 'required|min:6'
        ]);

        UserModel::create([
            'name' => $this->name,
            'email' => $this->email,
            'password' => $this->password
        ]);
        $this->resetInput();
    }
    public function edit($id)
    {
        $record = UserModel::findOrFail($id);
        $this->selected_id = $id;
        $this->name = $record->name;
        $this->email = $record->email;
        $this->password = $record->password;
        $this->updateMode = true;
    }
    public function update()
    {
        $this->validate([
            'selected_id' => 'required|numeric',
            'name' => 'required|min:5',
            'email' => 'required|email:rfc,dns',
            'password' => 'required|min:6'
        ]);
        if ($this->selected_id) {
            $record = UserModel::find($this->selected_id);
            $record->update([
                'name' => $this->name,
                'email' => $this->email,
                'password' => $this->password
            ]);
            $this->resetInput();
            $this->updateMode = false;
        }
    }
    public function destroy($id)
    {
        if ($id) {
            UserModel::destroy($id);
        }
    }
}

Define Routes

Now put the below routes in our web.php.

routes/web.php
Route::view('users', 'users');

Create and Setup blade File

Now we need to create a blade files for viewing the users component and from where we'll create/update user as well as we can see the list of user. So, create four files called

  1. users.blade.php under resources/views
  2. app.blade.php under resources/views/layouts
  3. create.blade.php under resources/views/livewire
  4. update.blade.php under resources/views/livewire

Now open the files replace with the following corresponding files.

users.blade.php

resources/views/users.blade.php
@extends('layouts.app')
@section('content')
    <div class="flex justify-center">
        @livewire('user')
    </div>
@endsection

app.blade.php

resources/views/layouts/app.blade.php
<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="csrf-token" content="{{ csrf_token() }}">
    <title>{{ config('app.name', 'Laravel') }}</title>

    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
    @livewireStyles
</head>
<body>
<div id="app">
    <nav class="navbar navbar-expand-md navbar-light bg-white shadow-sm">
        <div class="container">
            <a class="navbar-brand" href="{{ url('/') }}">
                {{ config('app.name', 'Laravel') }}
            </a>
            <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="{{ __('Toggle navigation') }}">
                <span class="navbar-toggler-icon"></span>
            </button>

        </div>
    </nav>

    <main class="py-4">
        @yield('content')
    </main>
</div>
@livewireScripts
</body>
</html>

user.blade.php (which we create in #step2)

resources/views/livewire/user.blade.php
<div class="container" style="background: #eeeeee; padding: 20px">
    <div class="row justify-content-center">
        <div class="col-md-8">

            @if (count($errors) > 0)
                <div class="alert alert-danger">
                    <a href="#" class="close" data-dismiss="alert">&times;</a>
                    <strong>Sorry!</strong> invalid input.<br><br>
                    <ul style="list-style-type:none;">
                        @foreach ($errors->all() as $error)
                            <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                </div>
            @endif


            @if($updateMode)
                @include('livewire.update')
            @else
                @include('livewire.create')
            @endif


            <table class="table table-striped" style="margin-top:20px;">
                <tr>
                    <td>NO</td>
                    <td>NAME</td>
                    <td>EMAIL</td>
                    <td>ACTION</td>
                </tr>

                @foreach($data as $row)
                    <tr>
                        <td>{{$loop->index + 1}}</td>
