Polling#

Demo#

Explanation#

<div
    data-signals="{count: 0}"
    data-on-interval__delay.1s="$count++"
>
    Count: <span data-text="$count">Count</span>
</div>

You can use the data-on-interval attribute to execute an expression at a regular interval. In this example, we are incrementing the count signal every 1 second.

An alternative approach is use the data-on-load attribute with the __delay modifier to control the polling frequency from the backend. Using this method, you can control back-pressure.

<div data-on-load__delay.1s="@get('/endpoint')">
    Count: 0
</div>

The backend endpoint can merge the same fragment but with a different delay value to determine the polling frequency.
