Stopping a pressure observer
The following example collects 20 samples and then disconnects the pressure observer to disable receiving any more pressure records.
js
const samples = [];
function pressureChange(records, observer) {
for (const record of records) {
samples.push(record.state);
// We only want 20 samples
if (samples.length === 20) {
observer.disconnect();
return;
}
}
}
try {
const observer = new PressureObserver(callback);
await observer.observe("cpu", {
sampleInterval: 1000, // 1000ms
});
} catch (error) {
// report error setting up the observer
}
