javascript - How can I automatically log warnings and errors from the console in Electron? -

i'd log these automatically generated errors , warnings in application can debug issues users have, far i've not been able find solution logging these. know of package or method?

thank you.

the basic idea listen errors subscribing window.onerror:

window.onerror = function (msg, url, lineno, columnno, error) {   // log server    return false; } 

but browsers don't provide stacktrace, have wrap functions calls @ top of stack chain try catch :

function wraperrors(fn) {   // don't wrap function more once   if (!fn.__wrapped__) {     fn.__wrapped__ = function () {           try {         return fn.apply(this, arguments);       } catch (e) {         logerrortoyourserver(e); // report error         throw e; // re-throw error       }     };   }    return fn.__wrapped__; }  var invoke = wraperrors(function(obj, method, args) {   return obj[method].apply(this, args); });  invoke(math, 'highest', [1, 2]); // no method math.highest 

this function has called:

• at start of application (e.g. in $(document).ready if use jquery)
• in event handlers, e.g. addeventlistener or $.fn.click
• timer-based callbacks, e.g. settimeout or requestanimationframe

for example:

$(wraperrors(function () { // application start   dosynchronousstuff1(); // doesn't need wrapped    settimeout(wraperrors(function () {     dosynchronousstuff2(); // doesn't need wrapped   });    $('.foo').click(wraperrors(function () {     dosynchronousstuff3(); // doesn't need wrapped   }); }));
