Most of the developers are facing a select2 style removing issue when livewire renders the component.

We can resolve this issue by using a livewire javascript hook.

Here is my screen with select2 before livewire component rendering.

And when the livewire component is refreshed means re-render the select2 style is gone ☹️

How to Fix it ?? 🤔

Well, you just need to add some JQuery code to your livewire component. Here we are going to use afterDomUpdate webhook of livewire. add the following code to your livewire component :

document.addEventListener('livewire:load', function (event) {
   window.livewire.hook('afterDomUpdate', () => {         
   $('#select2ID').select2();     
   }); 
});

livewire:load is listening events when the livewire component is loaded and we can add our code within it.

And now when your livewire component is refreshed your select2 style will be still there as we are again applying it.

Laravel Livewire is used to build dynamic web pages that work without ajax or any javascript code. We can build dynamic components with livewire with less code and more functionalities.

I hope this basic introduction will be enough to start laravel livewire.

Now let's move to the installation steps, and I hope you already have set up your laravel project.

Install Livewire

 composer require livewire/livewire 

Include the javascript and styles (On your master blade file)

  ...      
@livewireStyles   

   ...
     @livewireScripts

Create Your Component

Here we are going to create a component to create a summation of 2 values without hitting any buttons, it will do a summation of 2 values as you type in text boxes.

Now let's create our component by hitting the following command :

php artisan make:livewire Summation

it will create 2 files as shown below:

// app/Http/Livewire/Summation/php
namespace App\Http\Livewire;

use Livewire\Component;

class Summation extends Component
{
    public function render()
    {
        return view('livewire.summation');
    } 
}

// resources/views/livewire/summation.blade.php

Include the component

Include the created component to your view where you want to show.

    ...
    @livewireStyles

    ...

    @livewireScripts

Now let's first do a change in our livewire component Summation.php

namespace App\Http\Livewire;

use Livewire\Component;

class Summation extends Component
{ 
   public $value1 = 0;
   public $value2 = 0;
   public $sum = 0;

   public function mount()
   {
      $this->sum = 0;
   }

   public function render()
   {
      $this->sum = $this->value1 + $this->value2;

      return view('livewire.summation');
   }
 }

Here we have to take 2 public properties value1, value2, and sum. and in the mounting method (which will be called when the page is loaded the first time) I have replaced the sum property value to 0.

And In the render method, I have done a summation of the 2 public property values. which will be directly accessed values of input from blade files directly here. but how ?? we will see soon.

Now let's change the livewire blade component.

  

Here we have bound all properties by using wire:model. so as we will type in input box 1 it will be directly accessed by $value1 into the component.

and the property $sum will be changed as we change the input box values.

So that's how cool livewire is. you can create different dynamic components as you need by using livewire.

Livewire is a very awesome thing that I have ever seen, the old school developers are still using the jquery and ajax concept to not refresh the page. But forget the jquery and ajax stuff. If you are good at PHP then you can do the same with Laravel Livewire.

Wait what?

Load dynamic data on the page without using ajax? Yes, it is possible with Laravel Livewire. So that is all about laravel livewire, and in this tutorial, we will see how to build laravel pagination with laravel livewire.

Let's start and I hope you have already set up the livewire. Let's say you already have created a component named UsersListing Now in the users listing, we want to paginate all users and we will list 10 records per page.

How to use pagination with Laravel Livewire

Livewire provides a trait called WithPagination and you have to add it into your component UsersListing. Check out the following code:

use Livewire\WithPagination; 
use Livewire\Component; 
class UsersListing extends Component 
{ 
   use WithPagination;

   public function render() 
     { 
       return view('livewire.users.index', [ 'users' => User::paginate(10), ]); 
     } 
} 

And to load pagination you have to add the following code:

@foreach ($users as $user) ... 

@endforeach {{ $users->links() }} 

That's it, and your laravel pagination now works like charm without page refresh. There is much more about pagination like how to use it with a custom view, how to use it with a custom theme. We will see it in our next tutorial, until then enjoy the code
