I have a Livewire component and I want to do some async operations with it. However I could not figure out how to force refresh the update whenever I need.
To illustrate the problem, check out the example below.
Think like I'm trying to create a stop-watch. I'll click a button to start the stop-watch and everytime the $counter changes, I want to dispatch the value to my view.
class MyComponent extends Component {
public $counter = 0;
public function startTimer() {
for ($i = 0; $i < 10; $i++) {
$this->counter = $this->counter + 1;
// I want to tell "send data to view/update data in view here"
sleep(3);
}
}
}
<button wire:click="startTimer">Start</button>
<h1>{{ $counter }}</h1>
This is a dummy example and I don't want to do it with polling.
Is there a way to tell to component something like$this->updateDataInView()
?
In Livewire you can use the magic method$refresh
to manually refresh the view.
Option 1, in the view
<div>
<button wire:click="$refresh">Reload Component</button>
</div>
See also a blog post on this.
Option 2, inside the component class
protected $listeners = [
'refreshComponent' => '$refresh'
];
Here you need to emit therefreshComponent
event, of course.
