Chrome Extension - event page inactive after less than 20 seconds

Question

I am trying to create a feed reader that checks for an updated version of the feed every hour or so.

My problem is that the event page seems to turn inactive after

Answer 1

Using setInterval to periodically run some code works fine on background pages, but not on event pages, because the event page goes inactive when the page is idle for a long while.

The correct way to schedule a periodic task on event pages is to use the chrome.alarms API:

chrome.alarms.onAlarm.addListener(function(alarm) {
    if (alarm.name == 'name-of-alarm') {
        // Do something...
        testFunc();
    }
});

// Create the alarm:
chrome.alarms.create('name-of-alarm', {
    periodInMinutes: 60
});
