title: How to debug Angular2 in Chrome
body: <p>All:</p>
  
  <p>I am pretty new to Angular2, I find it is even harder than Angular1 to debug in Chrome( this is just my feeling, when I follow the tutorial on Angular2 official site, when there is error in the code, most time, the console output is from system.js or angular.dev.js etcs, I do not remember what js file names those error from, but one thing is most time, it can not helpfully point out the real place where the error originated). </p>
  
  <p>I wonder where can I find a tutorial about how to trace back the error in Chrome for Angular2?</p>
  
  <p>Thanks</p>
