Plugins update with Script

[mchandr]

Is there any way the plugins can be updated using background scripts, other than directly updating from UI or downloading it from store?

(function() {

    var grSSA = new GlideRecord('sys_store_app');

    grSSA.addActiveQuery();

    grSSA.addQuery('update_available', true);

    grSSA.setLimit(10);

    grSSA.query();

    if (grSSA.next()) {

        var storeVersion = grSSA.getValue('latest_version');

        var appSysId = grSSA.getUniqueValue();

        try {

            var worker = new sn_appclient.AppUpgrader();

            worker.upgrade(appSysId, storeVersion, false);

            gs.print("SUCCESS: Remote handshake completed! Upgrade task handed over to background node.");

            gs.print("Check 'sys_upgrade_history.list' to monitor progress.");

        } catch (ex) {

            gs.print("ERROR during upgrade processing: " + ex);

        }

    } else {

        gs.print("ERROR: Could not find any app record matching ID: " + targetAppId);

    }

})();
