What does it do?

Provides JavaScript error details in a readable format. You can log these errors remotely by enabling remoteLogging. After enabling, logerr will send a post request to the desired action/url with exception details along with custom parameters (if provided using additionalParams).

Install via :-


bower install logerr


Download logerr.js and follow the setup instructions below.


Just include logerr.js file and the init() i.e initializer in the <head> section of your page, before you include any other JavaScript. init() will initialize the lib, where later you can pass an object to customize.

<!DOCTYPE html>
<html lang="en">
    <script src="logerr.js"></script>

Enable remote logging

Make sure you have CORS enabled if logging cross-domain.

//Request type is POST

  remoteLogging: true, //Checkout https://github.com/i-break-codes/logerr-remote
  remoteSettings: {
    url: 'REMOTE_URL',
    additionalParams: {
      logged_by: 'Sam'
    successCallback: function () {
      console.log('Im logged.');
    errorCallback: function () {
      console.log('Err! Something went wrong.');

Also checkout Logerr Remote to log these exceptions remotely. (Powered by NodeJS)
