Debugging AngularJS with Batarang
Debugging most of the AngularJS part of your MEAN application is usually done in the browser. However, debugging the internal operations of AngularJS can be a bit trickier. For this purpose, the AngularJS team created a Chrome extension called Batarang. Batarang extends the Chrome Developer Tools with a new tab where you can debug different aspects of your AngularJS application. Installing Batarang is quite straightforward; all you have to is to visit the Chrome web store at https://chrome.google.com/webstore/detail/angularjs-batarang/ighdmehidhipcmcojjgiloacoafjmpfk and install the Chrome extension.
Note
Batarang will only work on the Google Chrome browser.
