The type read-only property of the WakeLockSentinel interface returns a string representation of the currently acquired WakeLockSentinel type.
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.
This example shows an asynchronous function that acquires a WakeLockSentinel, then logs the type to the console.
const requestWakeLock = async () => {
wakeLock = await navigator.wakeLock.request("screen");
console.log(wakeLock.type); // logs 'screen'
};
requestWakeLock();
