IdleDetector.start()
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The start()
method of the IdleDetector
interface returns a
Promise
that resolves when the detector starts listening for changes in the
user's idle state. This
method takes an optional options
object with the threshold
in milliseconds
where inactivity should be reported and signal
for an AbortSignal
to abort
the idle detector.
Syntax
IdleDetector.start();
IdleDetector.start(options);
Parameters
options
Optional-
An object with the following properties:
threshold
: The minimum number of idle milliseconds before reporting should begin.signal
: A reference to anAbortSignal
instance allowing you to abort idle detection.
Return Value
A Promise
.
Examples
The following example shows how to start idle detection using the options
argument. It retrieves an instance of AbortSignal
from an instance of AbortController
.
const controller = new AbortController();
const signal = controller.signal;
await idleDetector.start({
threshold: 60_000,
signal,
});
console.log('IdleDetector is active.');
