How to Create a Livewire Component in Laravel 12 (Guide)

Building interactive user interfaces in Laravel no longer requires heavy JavaScript frameworks. With Livewire 3.x and Laravel 12, you can create dynamic, reactive components using PHP and Blade alone.

In this guide, you’ll learn how to create a Livewire component in Laravel 12, step by step. This tutorial is beginner-friendly and practical, making it ideal for developers who want clean, maintainable solutions.

What Is a Livewire Component?

A Livewire component is a self-contained unit that combines:

PHP logic (component class)
Blade markup (component view)

Livewire handles communication between the browser and the server automatically, allowing your UI to update without full page reloads.

Prerequisites

Before starting, make sure you have:

PHP 8.2 or higher
Laravel 12 installed
Basic understanding of Blade templates

Installing Livewire in Laravel 12

Install Livewire using Composer:

composer require livewire/livewire

Then include Livewire assets in your main layout file:

@livewireStyles
@livewireScripts

That’s all you need to get started.

Creating Your First Livewire Component

Use the Artisan command:

php artisan make:livewire Counter

This generates:

app/Livewire/Counter.php
resources/views/livewire/counter.blade.php

Include the component in a Blade file:

<livewire:counter />

Understanding the Component Structure

Component Class (PHP)

namespace App\Livewire;

use Livewire\Component;

class Counter extends Component
{
    public int $count = 0;

    public function increment()
    {
        $this->count++;
    }

    public function render()
    {
        return view('livewire.counter');
    }
}

Component View (Blade)

<button wire:click="increment">
    Increment {{ $count }}
</button>

Livewire automatically syncs the UI when $count changes.

Handling User Interaction

Livewire listens to events using directives like:

wire:click
wire:model
wire:submit

This makes handling user actions intuitive and readable.

Passing Data to Livewire Components

You can pass parameters to components like this:

<livewire:counter :start="10" />

Then receive them in the component:

public function mount(int $start)
{
    $this->count = $start;
}

Best Practices for Livewire Components

Keep components small and focused
Avoid heavy database queries in render()
Use computed properties where possible
Reuse components across pages

These practices improve performance and maintainability.

Common Mistakes to Avoid

Performing logic inside Blade views
Overusing Livewire for static content
Forgetting pagination for large datasets

Avoiding these mistakes will save time and headaches.
