Key Features of Laravel Livewire
Now, let’s take a look at the important features of Livewire. So, that we can get to know why we can use Livewire. These are the following:
Reactive Components
The Livewire introduces the concept of reactive components. These are PHP classes that represent a part of your web page and include both the view (Blade template) and the logic. Livewire makes it easy to bind data and actions to the component. So changes to the component’s state automatically trigger updates in the browser.
No JavaScript Framework Required
One of the most significant advantages of using Livewire is that it reduces the reliance on JavaScript frameworks like React, Vue.js, Angular, etc. While these frameworks are powerful, they can introduce complexity and a steep learning curve. However, Livewire allows you to create interactive features with PHP and Laravel’s Blade templating engine.
Real-Time Validation and Error Handling
The next amazing feature of Livewire is Real-time validation for form fields. Yes, this provides real-time form validation and error handling. You can validate user input as they type, making the form-filling experience smooth and user-friendly. Also, the error messages are displayed instantly. So it provides immediate feedback to users in terms of any validation errors.
Lifecycle Hooks
Livewire components have lifecycle hooks that allow you to define actions that should occur at different stages of a component’s lifecycle. For example, you can perform actions when a component is initialized, updated, or removed from the DOM.
Server-Side Rendering
With Livewire, the rendering happens on the server side. So, it helps in reducing the amount of JavaScript required on the client side. This can lead to faster initial page loads and better SEO performance.
These are the important features of Livewire. However, we will work on these in our upcoming posts. For now, let’s quickly dive into the installation and kickstart with Laravel Livewire.

Getting Started with Livewire in Laravel 10
Now that we’ve covered the key features of Livewire. Therefore, let’s dive into how to get started with Laravel Livewire.
Prerequisites
Before we dive into the hands-on part, ensure you have the following prerequisites in place:
- A basic understanding of PHP and Laravel.
- A Laravel project up and running. If you don’t have one, you can create a new project using Composer.
Step 1 – Create a Laravel Project For Livewire Setup
For creating the Laravel project, simply open the terminal and play with the below command.
composer create-project --prefer-dist laravel/laravel laravel-livewire-appI am assuming you are ready with the Laravel project. Hence, I am moving to the next step of installation of Livewire.

Step 2 – Installing Laravel Livewire
Navigate to the project folder. Now, let’s get Livewire installed in your Laravel project. Open your terminal and run the following command:
composer require livewire/livewireThis command will download and install the Livewire package into your Laravel project.
After the successful installation of Livewire, you will have to import it’s style and script in your blade file.
Step 3 – Import Livewire Styles and Scripts
In order to use Livewire, you will have to import it in your main blade file or wherever you want in your Laravel project.
Here, I am going to create a master blade for it. So that I can use it globally across all the other views in our project. It totally depends on your project if you don’t want to import it globally in the master layout then you can import it in any single blade file as well.
So, the livewireStyles will go between the head tag and the livewireScripts will go before closing the body in your blade file.
Take a look at the below syntax.
<!doctype html><head> .... .... @livewireStyles</head><body> .... .... ....@livewireScrips</body></html>So, after creating the blade file as master.blade.php. I have imported the styles and scripts of the Livewire as shown below.
<!doctype html><html lang="en"><head> <title>Kickstart of Laravel Livewire</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Other CSS Libraries or import --> .... .... <!-- Livewire Styles --> @livewireStyles</head><body> <main class="pt-3 px-5"> @yield('content') </main> <!-- Other JavaScript Libraries and Scripts --> .... .... <!-- Livewire Scripts --> @livewireScripts </body></html>Now, link this blade with any of your route and run your application to see the changes. For that, you will have to click on the page source by doing right click in the browser.
In the head section, you will notice the Livewire has added some styles over there.
Similary, you will notice in the scripts section, livewire has added Livewire.js and some script as well.
So, behind the scene, livewire will work based on these added styles and scripts to make Ajax call. However, we will discuss this more on the upcoming tutorials.
As of now, let’s see how you can create your first Livewire component in Laravel.
Step 4 – Creating Your First Livewire Component
For creating the livewire component, you will have to hit the below command.
php artisan make:livewire "ComponentName"Here, the artisan command will be used to create livewire component. You will have to put the desired component name.
I am going to create a first component as HelloWorld.
php artisan make:livewire HelloWorldThe command will create a component having two files. That is a PHP class file and a blade (view) file.
- The class file will be located in the app/Http/Livewire folder. Here, you can write the functional logic.
- But, the blade file will be created in the resources/views/livewire folder. This will be used to render the HTML part.
While creating the component in Livewire, it will create the livewire folder automatically for both (Class and View).
Step 5 – Building Your Component
Open the HelloWorld.php file in your preferred code editor. You’ll see something like this:
<?phpnamespace App\Http\Livewire;use Livewire\Component;class HelloWorld extends Component{ public function render() { return view('livewire.hello-world'); }}Let me give you the explanation on above snippet.
- We have the render() function inside the component. This render() function specifies the Blade view that will be used to render your component.
Now, open the corresponding Blade template at resources/views/livewire/hello-world.blade.php. This is where you’ll define the HTML and user interface for your component.
Let’s add something inside that blade file.
<div> <h1>Hello, Livewire!</h1></div>Yeah, it’s done. Now, you have to include this component in a blade view in order to see the result.
Step 6 – Including the Component in a View
To include your Livewire component in a view, you can use the @livewire Blade directive. For instance, let’s include our HelloWorld component in the master.blade.php file.
<!doctype html><html lang="en"><head> <title>Kickstart of Laravel Livewire</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Livewire Styles --> @livewireStyles</head><body> <main class="pt-3 px-5"> @livewire('hello-world') </main> <!-- Livewire Scripts --> @livewireScripts</body></html>After importing the component in the master blade, you will have to render this blade file. Hence, we can do this in route itself without any controller.
<?phpuse App\Http\Controllers\BookController;use Illuminate\Support\Facades\Route;/*|--------------------------------------------------------------------------| Web Routes|--------------------------------------------------------------------------|| Here is where you can register web routes for your application. These| routes are loaded by the RouteServiceProvider and all of them will| be assigned to the "web" middleware group. Make something great!|*/Route::get('/livewire', function() { return view('master');});That’s it, now you can run the application. Visit http://localhost:8000/livewire in your web browser, and you should see your Hello, Livewire! message displayed.
Consequently, you will see the result as shown below.
Congratulations, you’ve successfully created and included your first Livewire component in Laravel.
