Polling is a technique used in web applications to "poll" the server (send requests on a regular interval) for updates. It's a simple way to keep a page up-to-date without the need for a more sophisticated technology like WebSockets.

Basic usage

Using polling inside Livewire is as simple as adding wire:poll to an element.

Below is an example of a SubscriberCount component that shows a user's subscriber count:

namespace App\Livewire;
use Illuminate\Support\Facades\Auth;
use Livewire\Component;
class SubscriberCount extends Component
public function render()
return view('livewire.subscriber-count', [
'count' => Auth::user()->subscribers->count(),
<div wire:poll>
Subscribers: {{ $count }}

Normally, this component would show the subscriber count for the user and never update until the page was refreshed. However, because of wire:poll on the component's template, this component will now refresh itself every 2.5 seconds, keeping the subscriber count up-to-date.

You can also specify an action to fire on the polling interval by passing a value to wire:poll:

<div wire:poll="refreshSubscribers">
Subscribers: {{ $count }}

Now, the refreshSubscribers() method on the component will be called every 2.5 seconds.

Timing control

The primary drawback of polling is that it can be resource intensive. If you have a thousand visitors on a page that uses polling, one thousand network requests will be triggered every 2.5 seconds.

The best way to reduce requests in this scenario is simply to make the polling interval longer.

You can manually control how often the component will poll by appending the desired duration to wire:poll like so:

<div wire:poll.15s> <!-- In seconds... -->
<div wire:poll.15000ms> <!-- In milliseconds... -->

Background throttling

To further cut down on server requests, Livewire automatically throttles polling when a page is in the background. For example, if a user keeps a page open in a different browser tab, Livewire will reduce the number of polling requests by 95% until the user revisits the tab.

If you want to opt-out of this behavior and keep polling continuously, even when a tab is in the background, you can add the .keep-alive modifier to wire:poll:

<div wire:poll.keep-alive>

Viewport throttling

Another measure you can take to only poll when necessary, is to add the .visible modifier to wire:poll. The .visible modifier instructs Livewire to only poll the component when it is visible on the page:

<div wire:poll.visible>

If a component using wire:visible is at the bottom of a long page, it won't start polling until the user scrolls it into the viewport. When the user scrolls away, it will stop polling again.
