Introduction
What is Laravel Livewire?
Laravel Livewire is an open-source PHP framework that allows developers to quickly and easily create dynamic, reactive user interfaces (UIs) without writing JavaScript. It is based on the popular PHP web application framework, Laravel, and provides a simple and intuitive way for developers to create dynamic UIs that can interact with the server without refreshing the page.
Livewire allows developers to quickly create complex, dynamic UIs with just a few lines of code. It is designed to make it easy for developers to create UIs that can interact with the server without relying on complex JavaScript libraries. Livewire components are written using a simple, intuitive syntax that is similar to other Laravel components, such as controllers and models.
Livewire is designed to be used with the Laravel framework, but it can also be used with other frameworks, such as Symfony and Zend. The framework supports a wide range of features, such as AJAX requests, form validation, and data binding. It also supports advanced features, such as reactive components, which allow developers to instantly update the UI when a value changes on the server.
Livewire is easy to learn and use, making it a great choice for developers who are just starting out with dynamic UIs. It also provides a powerful and efficient way for developers to create dynamic UIs without knowing a lot of JavaScript. Livewire is fast, reliable, and secure, making it a great choice for creating dynamic UIs for any project.

Prerequisites
Laravel Livewire is a modern front-end framework for Laravel, allowing developers to create dynamic, reactive, and interactive user interfaces without writing any JavaScript. Livewire combines the ease of data binding, composability, and simplicity of Vue.js with the robustness of Laravel to make building dynamic applications easier than ever.
Before you can start developing with Laravel Livewire, there are a few prerequisites you need to have in place.
First and foremost, you need to have a basic understanding of Laravel and its components. If you’ve never used Laravel before, it is highly recommended that you take some time to familiarize yourself with the framework. There are plenty of tutorials and resources available online to help you out.
You should also be familiar with modern web technologies such as HTML, CSS, and JavaScript. Although Livewire does not require you to write any JavaScript, it does rely on JavaScript to communicate with the server and render dynamic components.
Finally, you will need to have a working installation of the Laravel framework. You can find the instructions for installing Laravel here. Once you have a working installation, you’ll need to install the Livewire package. You can find the instructions for doing so here.
Once you have all of these prerequisites in place, you’re ready to start developing with Laravel Livewire. Have fun!
Setting up Laravel Livewire
In this article, we'll walk through the steps of setting up Laravel Livewire with an example. We'll start by creating a new Laravel project and installing Livewire. Then, we'll create a simple Livewire component that displays the current date and time. Finally, we'll add some live updating functionality to the component.
Create a new Laravel project
The first step is to create a new Laravel project. You can do this by running the following command in your terminal:
composer create-project --prefer-dist laravel/laravel livewire-example
Install Livewire
Now that you have a new Laravel project, you can install Livewire by running the following command in your terminal:
composer require livewire/livewire
Create a Livewire component
Livewire components are the building blocks of Livewire applications. They contain the logic and data that are used to render the frontend. To create our first component, run the following command in your terminal:
php artisan make:livewire date-time
This will create a new file called DateTime.php
in the app/Http/Livewire
directory. This is where we will define the logic for our component.
Add logic to the component
Open the DateTime.php
file and add the following code:
namespace App\Http\Livewire;
use Livewire\Component;
class DateTime extends Component
{
public $time;
public function mount()
{
$this->time = now();
}
public function render()
{
return view('livewire.date-time');
}
}
This code defines a Livewire component called DateTime
. The mount()
method is called when the component is first created, and we use it to set the $time
variable to the current date and time. The render()
method is used to render the view that will display the data.
Create the view
Now that we have defined the logic for our component, we need to create the view that will display the data. To do this, create a new file called date-time.blade.php
in the resources/views/livewire
directory and add the following code to it:
<div>
The current date and time is {{ $time }}
</div>
This will display the value of the $time variable.
Add the component to a page
Now that we have the component and the view, we need to add the component to a page. To do this, open the resources/views/welcome.blade.php
file and add the following code to it:
@livewire('date-time')
This will display the DateTime
component on the page.
Add live updating functionality
Finally, we can add some live updating functionality to the component. To do this, open the DateTime.php
file and add the following code to it:
public function updatedTime()
{
$this->time = now();
}
This will update the $time variable every time the updatedTime()
method is called. To call the method, we need to add the following code to the date-time.blade.php
view:
@livewire('date-time', ['updateTime' => true])
This will call the updatedTime()
method every second, causing the date and time to be updated automatically.
Responding to User Input
Responding to user input is an important part of any web application, and Livewire makes it easy. Livewire provides a simple, intuitive API to handle user input with JavaScript. It provides a reactive interface, so when a user interacts with an element it is updated in real-time. This makes it easier to create dynamic and interactive user interfaces.
Livewire provides a number of ways to respond to user input. For example, you can use the built-in JavaScript functions to trigger a response when a user interacts with an element. You can also use the built-in event handlers to respond to user input. For example, you can use the onChange
event to respond to a user changing the value of an input field, or the onSubmit
event to respond to a user submitting a form.
Livewire also provides a way to create custom components that can be used to respond to user input. Custom components allow you to create reusable pieces of code that can be used in multiple places in your application. For example, you could create a custom component that displays a confirmation dialog when a user clicks a button. This allows you to easily reuse the code throughout your application and keep it DRY.
Finally, Livewire provides a way to create custom JavaScript functions that can be used to respond to user input. For example, you can create a custom function that displays a confirmation dialog when a user clicks a button. This makes it easy to create dynamic user interfaces and quickly respond to user input.
Conclusion
Laravel Livewire is a relatively new library created by the founder of Laravel, Taylor Otwell. It is a full-stack framework for creating powerful, interactive web applications without leaving the comfort of your PHP code. It allows developers to create dynamic, responsive front-end user interfaces with minimal effort.
Livewire is based on the concept of reactive components, which are defined with PHP classes. These components can be used to create powerful web applications with minimal JavaScript code. Livewire components communicate with the server over AJAX, allowing for a smooth, user-friendly experience.
