WakeLockSentinel: type property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The type read-only property of the WakeLockSentinel interface returns a string representation of the currently acquired WakeLockSentinel type.

Value

A string representation of the currently acquired wake lock type. Currently, the value is always screen, which represents a screen wake lock. It prevents devices from dimming or locking the screen.

Examples

This example shows an asynchronous function that acquires a WakeLockSentinel, then logs the type to the console.

js
const requestWakeLock = async () => {
  wakeLock = await navigator.wakeLock.request("screen");
  console.log(wakeLock.type); // logs 'screen'
};

requestWakeLock();
