Electron windows are rendered in their own process. Because of this there is little if any communication between main process and render processes. The best you can do is catch errors in the render process and use Electrons IPC module to pass them back to your main process.

In your render process:

var ipc = require('electron').ipcRenderer;
window.onerror = function(error, url, line) {
    ipc.send('errorInWindow', error);
};

In your main process:

var ipc = require('electron').ipcMain;

ipc.on('errorInWindow', function(event, data){
    console.log(data)
});

Additionally your main process can watch for a limited set of events directly on the window (or on the windows webContents):

window.on('unresponsive', function() {
    console.log('window crashed');
});

...

window.webContents.on('did-fail-load', function() {
    console.log('window failed load');
});
