Debug Angular App - Adding a breakpoint is taking too much time

Open vhristov5555 opened this issue 6 years ago • 1 comments

  1. Create angular app tns create testNG --ng
  2. Run debug tns debug android
  3. Add a breakpoint in some ts file Actual: When you add a breakpoint you should wait some time around 10 seconds Expected: Adding a breakpoint should be as fast as in javascript app comment: In HMR this is causing a late response to changes in ts files.
