Lifecycle Hooks

Class Hooks

Each Livewire component undergoes a lifecycle (mount, updating, updated). Lifecycle hooks allow you to run code at any part of the component's lifecyle, or before specific properties are updated.

Hooks	Description
mount	Runs once, immediately after the component is instantiated, but before `render()` is called
hydrate	Runs on every request, immediately after the component is hydrated, but before an action is performed, or `render()` is called
updating	Runs before any update to the Livewire component's data
updated	Runs after any update to the Livewire componenta's data
updatingFoo	Runs before a property called `$foo` is updated
updatedFoo	Runs after a property called `$foo` is updated

use Livewire\Component;

class HelloWorld extends Component
{
    public $foo;

    public function mount()
    {
        //
    }

    public function hydrate()
    {
        //
    }

    public function updating($name, $value)
    {
        //
    }

    public function updatingFoo($value)
    {
        //
    }

    public function updatedFoo($value)
    {
        //
    }

    public function updated($name, $value)
    {
        //
    }
}

Javascript Hooks

Livewire gives you the opportunity to execute javascript during certain events.

Hooks	Description
beforeDomUpdate	Runs after Livewire receives a response from the server, but before any DOM diffing/patching takes place
afterDomUpdate	Runs after livewire updates the DOM

<script>
    document.addEventListener("livewire:load", function(event) {
        window.livewire.hook('beforeDomUpdate', () => {
            // Add your custom JavaScript here.
        });

        window.livewire.hook('afterDomUpdate', () => {
            // Add your custom JavaScript here.
        });
    });
</script>
