debug nodejs

I have used console.log to debug Grunt for a long time until I found node-inspector

it is pretty easy to setup debug enviroment

1. install node-inspector globally

    npm install -g node-inspecor
   

2. inspect debug port

    node-inspecor &  //& means run in background
   

3. node –debug-brk $(whick grunt) task if you saw debugger listening on port 5858 then you success

4. open chrome goto http://localhost:8080/debug?port=5858

if you are working under windows. then you need enter the absolut path of node.exe as well as grunt-cli

D:\work\projects\itms>"c:\Program Files\nodejs\node.exe" --debug-brk "C:\Program
 Files\nodejs\node_modules\grunt-cli\bin\grunt" release

use node debug to debug node debug node js
