  • Download Laravel App
  • Create Routes
  • Create Model and Migration
  • Install Livewire
  • Create Livewire Component and View
  • Create Blade File
  • Run Project

Step 1 : Download Laravel 7

In this laravel livewire crud tutorial i will explain it from step by step. So download the latest laravel app by the following command.

composer create-project --prefer-dist laravel/laravel livewire

Step 2 : Create Routes

Now we need to create our routes. So paste this below code in web.php file.

routes/web.php

Route::view('contacts', 'users.contacts');

Here we used view route and users.contacts indicates blade view directories. So make it like below image.

Now paste this following code to contacts.blade.php.

resources/views/users/contacts.blade.php

@extends('layouts.app')
@section('content')
    <div class="flex justify-center">
        @livewire('contact')
    </div>
@endsection

Step 3 : Create Model and Migration

Now we have to create our model and migration to submit form data in database so that we can check laravel livewire example crud tutorial. So make it by below command.

php artisan make:model Contact -m

now open Contact model and paste below code.

app/Contact.php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Contact extends Model
{
    protected $guarded = [];
}

now add this two field to your contacts table and run migrate command to save it database.

database/migrations/create_contacts_table.php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateContactsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('contacts', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('contacts');
    }
}

and then run

php artisan migrate

Step 4 : Install Livewire

To setup livewire in your project, run below command

composer require livewire/livewire 

After running this command open your app.blade.php and paste this below code.

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="{{ asset('js/app.js') }}" defer></script>
    <link href="{{ asset('css/app.css') }}" rel="stylesheet">
    @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 class="collapse navbar-collapse" id="navbarSupportedContent">
                    <ul class="navbar-nav mr-auto">
                    </ul>
                    <ul class="navbar-nav ml-auto">
                        @guest
                            <li class="nav-item">
                                <a class="nav-link" href="{{ route('login') }}">{{ __('Login') }}</a>
                            </li>
                            @if (Route::has('register'))
                                <li class="nav-item">
                                    <a class="nav-link" href="{{ route('register') }}">{{ __('Register') }}</a>
                                </li>
                            @endif
                        @else
                            <li class="nav-item dropdown">
                                <a id="navbarDropdown" class="nav-link dropdown-toggle" href="#" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" v-pre>
                                    {{ Auth::user()->name }} <span class="caret"></span>
                                </a>

                                <div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown">
                                    <a class="dropdown-item" href="{{ route('logout') }}"
                                       onclick="event.preventDefault();
                                                     document.getElementById('logout-form').submit();">
                                        {{ __('Logout') }}
                                    </a>

                                    <form id="logout-form" action="{{ route('logout') }}" method="POST" style="display: none;">
                                        @csrf
                                    </form>
                                </div>
                            </li>
                        @endguest
                    </ul>
                </div>
            </div>
        </nav>

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

Step 5 : Create Livewire Component and View

Run the below command to create livewire view and component.

php artisan make:livewire contact

After running this command you will find two file in the following path app/Http/Livewire/Contact.php and resources/views/livewire/contact.blade.php

app/Http/Livewire/Contact.php

namespace App\Http\Livewire;
use App\Contact;
use Livewire\Component;
class Contact extends Component
{
    public $data, $name, $email, $selected_id;
    public $updateMode = false;

    public function render()
    {
        $this->data = Contact::all();
        return view('livewire.contact');
    }
    private function resetInput()
    {
        $this->name = null;
        $this->email = null;
    }
    public function store()
    {
        $this->validate([
            'name' => 'required|min:5',
            'email' => 'required|email:rfc,dns'
        ]);
        Contact::create([
            'name' => $this->name,
            'email' => $this->email
        ]);
        $this->resetInput();
    }
    public function edit($id)
    {
        $record = Contact::findOrFail($id);
        $this->selected_id = $id;
        $this->name = $record->name;
        $this->email = $record->email;
        $this->updateMode = true;
    }
    public function update()
    {
        $this->validate([
            'selected_id' => 'required|numeric',
            'name' => 'required|min:5',
            'email' => 'required|email:rfc,dns'
        ]);
        if ($this->selected_id) {
            $record = Contact::find($this->selected_id);
            $record->update([
                'name' => $this->name,
                'email' => $this->email
            ]);
            $this->resetInput();
            $this->updateMode = false;
        }
    }
    public function destroy($id)
    {
        if ($id) {
            $record = Contact::where('id', $id);
            $record->delete();
        }
    }
}

Step 6 : Create Blade File

Now create a folder structure like below image. We are in the last past of our livewire tutorial.

Now paste this below code to you blade file. Here we will create contact, create and update file to create our laravel livewire crud example.

resources/views/livewire/contact.blade.php

<div>
    
    <div class="col-md-6">

    @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>
                <td>{{$row->name}}</td>
                <td>{{$row->email}}</td>
                <td>
                    <button wire:click="edit({{$row->id}})" class="btn btn-sm btn-outline-danger py-0">Edit</button> | 
                    <button wire:click="destroy({{$row->id}})" class="btn btn-sm btn-outline-danger py-0">Delete</button>
                </td>
            </tr>
        @endforeach
    </table>
    </div>

</div>

resources/views/livewire/create.blade.php

<div>
    <div class="form-group">
        <label for="exampleInputPassword1">Enter Name</label>
        <input type="text" wire:model="name" class="form-control input-sm"  placeholder="Name">
    </div>
    <div class="form-group">
        <label>Enter Email</label>
        <input type="email" class="form-control input-sm" placeholder="Enter email" wire:model="email">
    </div>
    <button wire:click="store()" class="btn btn-primary">Submit</button>
</div>

resources/views/livewire/update.blade.php


<div>
    <input type="hidden" wire:model="selected_id">
    <div class="form-group">
        <label for="exampleInputPassword1">Enter Name</label>
        <input type="text" wire:model="name" class="form-control input-sm"  placeholder="Name">
    </div>
    <div class="form-group">
        <label>Enter Email</label>
        <input type="email" class="form-control input-sm" placeholder="Enter email" wire:model="email">
    </div>
    <button wire:click="update()" class="btn btn-primary">Update</button>
</div>

Now all are set to go. Just visit this below url to test our laravel livewire crud example project.

http://127.0.0.1:8000/contacts

Now if you checked it then i think you must say that if vue and blade had a baby it would be a jellyfish. Isn't it? Hope it can help you.
