In this post we will make Laravel Livewire Crud application from Scratch level. From this Laravel Livewire CRUD example, you can learn How to do CRUD operation in Laravel 7 framework by using Livewire package.

So now you have understand what is Laravel Livewire package and it is full stack framework in Laravel and by using this package we can make dynamic interfaces without loosing the comfort of Laravel framework. Now we have focused on Laravel Livewire CRUD application tutorial. From this tutorial you can learn how to use Livewire package in Laravel framework for perform Mysql insert update delete operation. For learn this things you have to follow following steps.
- Download Fresh Laravel 7 Framework
- Make Database Connection
- Create Mysql Table
- Create Model Class
- Install Livewire Package
- Create Livewire Component
- Run Laravel 7 Application
1. Download Fresh Laravel 7 Framework
In first step we have to download fresh copy of Laravel 7 framework. For download latest version of Laravel framework, we have to go to the command prompt and go to the directory in which you want to download Laravel 7 framework and write following command.
composer create-project --prefer-dist laravel/laravel livewire
This command will make livewire directory and under that directory it will download Laravel 7 framework. So this way we can download latest version of Laravel framework.
2. Make Database Connection
In second step we have to make Mysql database connection in Laravel 7 framework. For this we have open .env and under this file we have to define following mysql database configuration.
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=testing
DB_USERNAME=root
DB_PASSWORD=
The above configuration will make database connection in Laravel 7 framework.
3. Create Mysql Table
After making Mysql database connection, now we want to create table in Mysql database from this Laravel 7 application. So, first want to create migration file. So for create migration file we have to go the command prompt and write following command.
php artisan make:migration sampledata
This command will create migration file under database/migrations directive. So we have to open that file and under that file we have to define table column details, which you can find below.
database/migrations/2020_08_28_060357_sampledata.php
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class Sampledata extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('sampledatas', function(Blueprint $table) {
$table->id();
$table->text('first_name');
$table->text('last_name');
$table->text('gender');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('sampledatas');
}
}
Now we want to migrate above table defination to mysql database. For this we have go to the command prompt and write following command.
php artisan migrate
Above command will migrate table defination to mysql database and create sampledatas table in define mysql database.
4. Create Model Class
In next step we have to create model class file for perform mysql database related operation. So for create model class file, we have to go to the command prompt and write following command.
php artisan make:model Sampledata
This command will create Sampledata.php model class file in app directory. In this file we have to define table column name which you can find below.
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Sampledata extends Model
{
protected $fillable = ['first_name', 'last_name', 'gender'];
}
?>
5. Install Livewire Package
Now we have come on to the main part, how can we install Livewire package in Laravel 7 framework. So it is very easy, you have to just go to command prompt and write following command.
composer require livewire/livewire
This command will download Livewire package in Laravel 7 framework application and now we can use Livewire package in Laravel framework.
6. Create Livewire Component
For create livewire component in Laravel framework you should go to command prompt and run following command.
php artisan make:livewire posts
Above command will create two file in your project. One file at app/Http/Livewire/Posts.php and other file at resources/views/livewire/posts.blade.php. First file will use for back-end operation and second file will used for front-end operation for create CRUD application.
app/Http/Livewire/Posts.php
<?php
namespace App\Http\Livewire;
use Livewire\Component;
use App\Sampledata;
class Posts extends Component
{
public $sampledata, $first_name, $last_name, $gender, $data_id;
public function render()
{
$this->sampledata = Sampledata::all();
return view('livewire.posts');
}
public function resetInputFields()
{
$this->first_name = '';
$this->last_name = '';
$this->gender = '';
}
public function store()
{
$validation = $this->validate([
'first_name' => 'required',
'last_name' => 'required',
'gender' => 'required'
]);
Sampledata::create($validation);
session()->flash('message', 'Data Created Successfully.');
$this->resetInputFields();
$this->emit('userStore');
}
public function edit($id)
{
$data = Sampledata::findOrFail($id);
$this->data_id = $id;
$this->first_name = $data->first_name;
$this->last_name = $data->last_name;
$this->gender = $data->gender;
}
public function update()
{
$validate = $this->validate([
'first_name' => 'required',
'last_name' => 'required',
'gender' => 'required'
]);
$data = Sampledata::find($this->data_id);
$data->update([
'first_name' => $this->first_name,
'last_name' => $this->last_name,
'gender' => $this->gender
]);
session()->flash('message', 'Data Updated Successfully.');
$this->resetInputFields();
$this->emit('userStore');
}
public function delete($id)
{
Sampledata::find($id)->delete();
session()->flash('message', 'Data Deleted Successfully.');
}
}
resources/views/livewire/posts.blade.php
<div>
@if(session()->has('message'))
<div class="alert alert-success">{{ session('message') }}</div>
@endif
@include('livewire.create')
@include('livewire.update')
<br />
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Gender</th>
<th>Action</th>
</tr>
</thead>
<tbody>
@foreach($sampledata as $data)
<tr>
<td>{{ $data->first_name }}</td>
<td>{{ $data->last_name }}</td>
<td>{{ $data->gender }}</td>
<td>
<button data-toggle="modal" data-target="#updateModal" class="btn btn-primary btn-sm" wire:click="edit({{ $data->id }})">Edit</button>
<button wire:click="delete({{ $data->id }})" class="btn btn-danger btn-sm">Delete</button>
</td>
</tr>
@endforeach
</tbody>

7. Run Laravel 7 Application
At the end of the steps, we have to run Laravep application. So for run Laravel application, first we should go to command prompt terminal and write following command.
php artisan serve
This command will start Laravel server and provide you a base url of your Laravel application, which you can find below.
http://127.0.0.1:8000/
So, you may go to browser and paste above base url and you can run above Laravel 7 Crud application which has been made by using Livewire package.
