In this short snippet, we'll get started with running Livewire on an existing Laravel project.
To install Laravel Livewire you can make use of the composer package manager.
Step 1: Install Laravel Livewire
To install Laravel Livewire you can make use of the composer package manager.
composer require livewire/livewire
Step 2: Define The Livewire Styles and Scripts
Next, you have to define the livewire styles and scripts on the HTML head and body tag.
<!doctype html> <html> <head> <!-- ... --> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <link href="/tailwind.css" rel="stylesheet"> @livewireStyles </head> <body> <!-- ... --> @livewireScripts </body> </html>
Optional: Publish Config and Front-end Assets
If you want to publish the configuration which contains the settings for Livewire namespace, layouts and etc you can run the command below.
php artisan livewire:publish --config
For the assets, you can make use of this command.
php artisan livewire:publish --assets
It's also highly recommended to specify the above command in composer.json file to automatically update it when new version is available.
{
"scripts": {
"post-autoload-dump": [
"Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
"@php artisan package:discover --ansi",
"@php artisan vendor:publish --force --tag=livewire:assets --ansi"
]
}
}Step 3: Create Simple Livewire Counter Component
You can create a simple component using the "livewire:make" command. For this example, we'll be using the Tailwind CSS component for the front-end UI.
php artisan make:livewire counter
The content of the Component should be as follows.
<?php
class Counter extends Component
{
public $count = 0;
public function increment()
{
$this->count++;
}
public function render()
{
return view('livewire.counter');
}
}The content of the "counter" views component will be:
<div style="text-align: center">
<button wire:click="increment">+</button>
<h1>{{ $count }}</h1>
</div>Update the Laravel Blade Code
Now you can reference the Livewire counter component using the livewire tag like below.
<!doctype html> <html> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <link href="/tailwind.css" rel="stylesheet"> @livewireStyles </head> <body> <livewire:counter /> @livewireScripts </body> </html>
