Chrome extension for kiosk monitoring and reboot if necessary

I have a kiosk that handles portraits of people. He works in chrome.

One in 200 people who use a kiosk ends up freezing it during the process. When it freezes, I never get "ah snap", and the page is just curious.

I was wondering if it is possible to make an extension to control the page and check for heart rate - if this is not visible after 30 seconds, reload the window.

Any help would be great.

  • You have script content on the kiosk page, send a message every X seconds back to the wallpaper

    In the contents of the script:

    var port = chrome.extension.connect({ name: "keep-alive" });

port.postMessage('is-alive', { alive: true });

setInterval(function () {
    port.postMessage('is-alive', { alive: true });
}, 1000 * 15);

  • , ,

    :

    var last = Date.now();
var interval = 1000 * 15;

chrome.extension.onConnect.addListener(function (port) {
    if (port.name === 'keep-alive') {
        port.onMessage.addListener(function (data) {
            if (data.type === 'is-alive' && data.payload.alive === true) {
                last = Date.now();
            }
        });
    }
});

setInterval(function () {
    if (Date.now() - last > interval) {
        // Reload the tab...
    }
}, interval);
